+LLD 4.0.0 Release Notes
+=======================
+
+.. contents::
+ :local:
+
+Introduction
+============
+
+LLD is a linker which supports ELF (Unix), COFF (Windows) and Mach-O
+(macOS). It is generally faster than the GNU BFD/gold linkers or the
+MSVC linker.
+
+LLD is designed to be a drop-in replacement for the system linkers, so
+that users don't need to change their build systems other than swapping
+the linker command.
+
+This document contains the release notes for LLD 4.0.0.
+Here we describe the status of LLD, including major improvements
+from the previous release. All LLD releases may be downloaded
+from the `LLVM releases web site <http://llvm.org/releases/>`_.
+
+
+What's New in LLD 4.0?
+======================
+
+ELF Improvements
+----------------
+
+LLD provides much better compatibility with the GNU linker than before.
+Now it is able to link the entire FreeBSD base system including the kernel
+out of the box. We are working closely with the FreeBSD project to
+make it usable as the system linker in a future release of the operating
+system.
+
+Multi-threading performance has been improved, and multi-threading
+is now enabled by default. Combined with other optimizations, LLD 4.0
+is about 1.5 times faster than LLD 3.9 when linking large programs
+in our test environment.
+
+Other notable changes are listed below:
+
+* Error messages contain more information than before. If debug info
+ is available, the linker prints out not only the object file name
+ but the source location of unresolved symbols.
+
+* Error messages are printed in red just like Clang by default. You
+ can disable it by passing ``-no-color-diagnostics``.
+
+* LLD's version string is now embedded in a .comment section in the
+ result output file. You can dump it with this command: ``objdump -j -s
+ .comment <file>``.
+
+* The ``-Map`` option is supported. With that, you can print out section
+ and symbol information to a specified file. This feature is useful
+ for analyzing link results.
+
+* The file format for the ``-reproduce`` option has changed from cpio to
+ tar.
+
+* When creating a copy relocation for a symbol, LLD now scans the
+ DSO's header to see if the symbol is in a read-only segment. If so,
+ space for the copy relocation is reserved in .bss.rel.ro instead of
+ .bss. This fixes a security issue that read-only data in a DSO
+ becomes writable if it is copied by a copy relocation. This issue
+ was disclosed originally on the
+ `binutils mailing list <https://sourceware.org/ml/libc-alpha/2016-12/msg00914.html>`_.
+
+* Compressed input sections are supported.
+
+* ``--oformat binary``, ``--section-start``, ``-Tbss``, ``-Tdata``,
+ ``-Ttext``, ``-b binary``, ``-build-id=uuid``, ``-no-rosegment``,
+ ``-nopie``, ``-nostdlib``, ``-omagic``, ``-retain-symbols-file``,
+ ``-sort-section``, ``-z max-page-size`` and ``-z wxneeded`` are
+ supported.
+
+* A lot of linker script directives have been added.
+
+* Default image base address for x86-64 has changed from 0x10000 to
+ 0x200000 to make it huge-page friendly.
+
+* ARM port now supports GNU ifunc, the ARM C++ exceptions ABI, TLS
+ relocations and static linking. Problems with ``dlopen()`` on systems
+ using eglibc fixed.
+
+* MIPS port now supports input files in new R6 revision of MIPS ABIs
+ or N32 ABI. Generated file now contains .MIPS.abiflags section and
+ complete set of ELF headers flags.
+
+* Relocations produced by the ``-mxgot`` compiler flag is supported
+ for MIPS. Now it is possible to generate "large" GOT that exceeds the 64K
+ limit.
+
+COFF Improvements
+-----------------
+
+* Performance on Windows has been improved by parallelizing parts of the
+ linker and optimizing file system operations. As a result of these
+ improvements, LLD 4.0 has been measured to be about 2.5 times faster
+ than LLD 3.9 when linking a large Chromium DLL.

+Driver

+
+Introduction
+============
+
+This document describes the lld driver. The purpose of this document is to
+describe both the motivation and design goals for the driver, as well as details
+of the internal implementation.
+
+Overview
+========
+
+The lld driver is designed to support a number of different command line
+interfaces. The main interfaces we plan to support are binutils' ld, Apple's
+ld, and Microsoft's link.exe.
+
+Flavors
+-------
+
+Each of these different interfaces is referred to as a flavor. There is also an
+extra flavor "core" which is used to exercise the core functionality of the
+linker it the test suite.
+
+* gnu
+* darwin
+* link
+* core
+
+Selecting a Flavor
+^^^^^^^^^^^^^^^^^^
+
+There are two different ways to tell lld which flavor to be. They are checked in
+order, so the second overrides the first. The first is to symlink :program:`lld`
+as :program:`lld-{flavor}` or just :program:`{flavor}`. You can also specify
+it as the first command line argument using ``-flavor``::
+
+ $ lld -flavor gnu
+
+There is a shortcut for ``-flavor core`` as ``-core``.
+
+
+Adding an Option to an existing Flavor
+======================================
+
+#. Add the option to the desired :file:`lib/Driver/{flavor}Options.td`.
+
+#. Add to :cpp:class:`lld::FlavorLinkingContext` a getter and setter method
+ for the option.
+
+#. Modify :cpp:func:`lld::FlavorDriver::parse` in :file:
+ `lib/Driver/{Flavor}Driver.cpp` to call the targetInfo setter
+ for corresponding to the option.
+
+#. Modify {Flavor}Reader and {Flavor}Writer to use the new targtInfo option.
+
+
+Adding a Flavor
+===============
+
+#. Add an entry for the flavor in :file:`include/lld/Driver/Driver.h` to
+ :cpp:class:`lld::UniversalDriver::Flavor`.
+
+#. Add an entry in :file:`lib/Driver/UniversalDriver.cpp` to
+ :cpp:func:`lld::Driver::strToFlavor` and
+ :cpp:func:`lld::UniversalDriver::link`.
+ This allows the flavor to be selected via symlink and `-flavor`.
+
+#. Add a tablegen file called :file:`lib/Driver/{flavor}Options.td` that
+ describes the options. If the options are a superset of another driver, that
+ driver's td file can simply be included. The :file:`{flavor}Options.td` file
+ must also be added to :file:`lib/Driver/CMakeLists.txt`.
+
+#. Add a ``{flavor}Driver`` as a subclass of :cpp:class:`lld::Driver`
+ in :file:`lib/Driver/{flavor}Driver.cpp`.

+The ELF and COFF Linkers
+========================
+
+We started rewriting the ELF (Unix) and COFF (Windows) linkers in May 2015.
+Since then, we have been making a steady progress towards providing
+drop-in replacements for the system linkers.
+
+Currently, the Windows support is mostly complete and is about 2x faster
+than the linker that comes as a part of Micrsoft Visual Studio toolchain.
+
+The ELF support is in progress and is able to link large programs
+such as Clang or LLD itself. Unless your program depends on linker scripts,
+you can expect it to be linkable with LLD.
+It is currently about 1.2x to 2x faster than GNU gold linker.
+We aim to make it a drop-in replacement for the GNU linker.
+
+We expect that FreeBSD is going to be the first large system
+to adopt LLD as the system linker.
+We are working on it in collaboration with the FreeBSD project.
+
+The linkers are notably small; as of October 2016,
+the COFF linker is about 7k lines and the ELF linker is about 18k lines,
+while gold is 165K lines.
+
+The linkers are designed to be as fast and simple as possible.
+Because it is simple, it is easy to extend to support new features.
+It already supports several advanced features such section garbage
+collection and identical code folding.
+
+The COFF linker supports i386, x86-64 and ARM. The ELF linker supports
+i386, x86-64, x32, MIPS32, MIPS64, PowerPC, AMDGPU, ARM and Aarch64,
+although the quality varies depending on platform. By default, LLD
+provides support for all targets because the amount of code we have for
+each target is so small. We do not even provide a way to disable
+targets at compile time.
+
+There are a few key design choices that we made to achieve these goals.
+We will describe them in this document.
+
+The ELF Linker as a Library
+---------------------------
+
+You can embed LLD to your program by linking against it and calling the linker's
+entry point function lld::elf::link.
+
+The current policy is that it is your reponsibility to give trustworthy object
+files. The function is guaranteed to return as long as you do not pass corrupted
+or malicious object files. A corrupted file could cause a fatal error or SEGV.
+That being said, you don't need to worry too much about it if you create object
+files in the usual way and give them to the linker. It is naturally expected to
+work, or otherwise it's a linker's bug.
+
+Design
+======
+
+We will describe the design of the linkers in the rest of the document.
+
+Key Concepts
+------------
+
+Linkers are fairly large pieces of software.
+There are many design choices you have to make to create a complete linker.
+
+This is a list of design choices we've made for ELF and COFF LLD.
+We believe that these high-level design choices achieved a right balance
+between speed, simplicity and extensibility.
+
+* Implement as native linkers
+
+ We implemented the linkers as native linkers for each file format.
+
+ The two linkers share the same design but do not share code.
+ Sharing code makes sense if the benefit is worth its cost.
+ In our case, ELF and COFF are different enough that we thought the layer to
+ abstract the differences wouldn't worth its complexity and run-time cost.
+ Elimination of the abstract layer has greatly simplified the implementation.
+
+* Speed by design
+
+ One of the most important things in archiving high performance is to
+ do less rather than do it efficiently.
+ Therefore, the high-level design matters more than local optimizations.
+ Since we are trying to create a high-performance linker,
+ it is very important to keep the design as efficient as possible.
+
+ Broadly speaking, we do not do anything until we have to do it.
+ For example, we do not read section contents or relocations
+ until we need them to continue linking.
+ When we need to do some costly operation (such as looking up
+ a hash table for each symbol), we do it only once.
+ We obtain a handler (which is typically just a pointer to actual data)
+ on the first operation and use it throughout the process.
+
+* Efficient archive file handling
+
+ LLD's handling of archive files (the files with ".a" file extension) is different
+ from the traditional Unix linkers and similar to Windows linkers.
+ We'll describe how the traditional Unix linker handles archive files,
+ what the problem is, and how LLD approached the problem.
+
+ The traditional Unix linker maintains a set of undefined symbols during linking.
+ The linker visits each file in the order as they appeared in the command line
+ until the set becomes empty. What the linker would do depends on file type.
+
+ - If the linker visits an object file, the linker links object files to the result,
+ and undefined symbols in the object file are added to the set.
+
+ - If the linker visits an archive file, it checks for the archive file's symbol table
+ and extracts all object files that have definitions for any symbols in the set.
+
+ This algorithm sometimes leads to a counter-intuitive behavior.
+ If you give archive files before object files, nothing will happen
+ because when the linker visits archives, there is no undefined symbols in the set.
+ As a result, no files are extracted from the first archive file,
+ and the link is done at that point because the set is empty after it visits one file.
+
+ You can fix the problem by reordering the files,
+ but that cannot fix the issue of mutually-dependent archive files.
+
+ Linking mutually-dependent archive files is tricky.
+ You may specify the same archive file multiple times to
+ let the linker visit it more than once.
+ Or, you may use the special command line options, `--start-group` and `--end-group`,
+ to let the linker loop over the files between the options until
+ no new symbols are added to the set.
+
+ Visiting the same archive files multiple makes the linker slower.
+
+ Here is how LLD approached the problem. Instead of memorizing only undefined symbols,
+ we program LLD so that it memorizes all symbols.
+ When it sees an undefined symbol that can be resolved by extracting an object file
+ from an archive file it previously visited, it immediately extracts the file and link it.
+ It is doable because LLD does not forget symbols it have seen in archive files.
+
+ We believe that the LLD's way is efficient and easy to justify.
+
+ The semantics of LLD's archive handling is different from the traditional Unix's.
+ You can observe it if you carefully craft archive files to exploit it.
+ However, in reality, we don't know any program that cannot link
+ with our algorithm so far, so it's not going to cause trouble.
+
+Numbers You Want to Know
+------------------------
+
+To give you intuition about what kinds of data the linker is mainly working on,
+I'll give you the list of objects and their numbers LLD has to read and process
+in order to link a very large executable. In order to link Chrome with debug info,
+which is roughly 2 GB in output size, LLD reads
+
+- 17,000 files,
+- 1,800,000 sections,
+- 6,300,000 symbols, and
+- 13,000,000 relocations.
+
+LLD produces the 2 GB executable in 15 seconds.
+
+These numbers vary depending on your program, but in general,
+you have a lot of relocations and symbols for each file.
+If your program is written in C++, symbol names are likely to be
+pretty long because of name mangling.
+
+It is important to not waste time on relocations and symbols.
+
+In the above case, the total amount of symbol strings is 450 MB,
+and inserting all of them to a hash table takes 1.5 seconds.
+Therefore, if you causally add a hash table lookup for each symbol,
+it would slow down the linker by 10%. So, don't do that.
+
+On the other hand, you don't have to pursue efficiency
+when handling files.
+
+Important Data Strcutures
+-------------------------
+
+We will describe the key data structures in LLD in this section.
+The linker can be understood as the interactions between them.
+Once you understand their functions, the code of the linker should look obvious to you.
+
+* SymbolBody
+
+ SymbolBody is a class to represent symbols.
+ They are created for symbols in object files or archive files.
+ The linker creates linker-defined symbols as well.
+
+ There are basically three types of SymbolBodies: Defined, Undefined, or Lazy.
+
+ - Defined symbols are for all symbols that are considered as "resolved",
+ including real defined symbols, COMDAT symbols, common symbols,
+ absolute symbols, linker-created symbols, etc.
+ - Undefined symbols represent undefined symbols, which need to be replaced by
+ Defined symbols by the resolver until the link is complete.
+ - Lazy symbols represent symbols we found in archive file headers
+ which can turn into Defined if we read archieve members.
+
+* Symbol
+
+ A Symbol is a container for a SymbolBody. There's only one Symbol for each
+ unique symbol name (this uniqueness is guaranteed by the symbol table).
+ Each global symbol has only one SymbolBody at any one time, which is
+ the SymbolBody stored within a memory region of the Symbol large enough
+ to store any SymbolBody.
+
+ As the resolver reads symbols from input files, it replaces the Symbol's
+ SymbolBody with the "best" SymbolBody for its symbol name by constructing
+ the new SymbolBody in place on top of the existing SymbolBody. For example,
+ if the resolver is given a defined symbol, and the SymbolBody with its name
+ is undefined, it will construct a Defined SymbolBody over the Undefined
+ SymbolBody.
+
+ This means that each SymbolBody pointer always points to the best SymbolBody,
+ and it is possible to get from a SymbolBody to a Symbol, or vice versa,
+ by adding or subtracting a fixed offset. This memory layout helps reduce
+ the cache miss rate through high locality and a small number of required
+ pointer indirections.
+
+* SymbolTable
+
+ SymbolTable is basically a hash table from strings to Symbols
+ with a logic to resolve symbol conflicts. It resolves conflicts by symbol type.
+
+ - If we add Defined and Undefined symbols, the symbol table will keep the former.
+ - If we add Defined and Lazy symbols, it will keep the former.
+ - If we add Lazy and Undefined, it will keep the former,
+ but it will also trigger the Lazy symbol to load the archive member
+ to actually resolve the symbol.
+
+* Chunk (COFF specific)
+
+ Chunk represents a chunk of data that will occupy space in an output.
+ Each regular section becomes a chunk.
+ Chunks created for common or BSS symbols are not backed by sections.
+ The linker may create chunks to append additional data to an output as well.
+
+ Chunks know about their size, how to copy their data to mmap'ed outputs,
+ and how to apply relocations to them.
+ Specifically, section-based chunks know how to read relocation tables
+ and how to apply them.
+
+* InputSection (ELF specific)
+
+ Since we have less synthesized data for ELF, we don't abstract slices of
+ input files as Chunks for ELF. Instead, we directly use the input section
+ as an internal data type.
+
+ InputSection knows about their size and how to copy themselves to
+ mmap'ed outputs, just like COFF Chunks.
+
+* OutputSection
+
+ OutputSection is a container of InputSections (ELF) or Chunks (COFF).
+ An InputSection or Chunk belongs to at most one OutputSection.
+
+There are mainly three actors in this linker.
+
+* InputFile
+
+ InputFile is a superclass of file readers.
+ We have a different subclass for each input file type,
+ such as regular object file, archive file, etc.
+ They are responsible for creating and owning SymbolBodies and
+ InputSections/Chunks.
+
+* Writer
+
+ The writer is responsible for writing file headers and InputSections/Chunks to a file.
+ It creates OutputSections, put all InputSections/Chunks into them,
+ assign unique, non-overlapping addresses and file offsets to them,
+ and then write them down to a file.
+
+* Driver
+
+ The linking process is driven by the driver. The driver
+
+ - processes command line options,
+ - creates a symbol table,
+ - creates an InputFile for each input file and put all symbols in it into the symbol table,
+ - checks if there's no remaining undefined symbols,
+ - creates a writer,
+ - and passes the symbol table to the writer to write the result to a file.
+
+Link-Time Optimization
+----------------------
+
+LTO is implemented by handling LLVM bitcode files as object files.
+The linker resolves symbols in bitcode files normally. If all symbols
+are successfully resolved, it then runs LLVM passes
+with all bitcode files to convert them to one big regular ELF/COFF file.
+Finally, the linker replaces bitcode symbols with ELF/COFF symbols,
+so that they are linked as if they were in the native format from the beginning.
+
+The details are described in this document.
+http://llvm.org/docs/LinkTimeOptimization.html
+
+Glossary
+--------
+
+* RVA (COFF)
+
+ Short for Relative Virtual Address.
+
+ Windows executables or DLLs are not position-independent; they are
+ linked against a fixed address called an image base. RVAs are
+ offsets from an image base.
+
+ Default image bases are 0x140000000 for executables and 0x18000000
+ for DLLs. For example, when we are creating an executable, we assume
+ that the executable will be loaded at address 0x140000000 by the
+ loader, so we apply relocations accordingly. Result texts and data
+ will contain raw absolute addresses.
+
+* VA
+
+ Short for Virtual Address. For COFF, it is equivalent to RVA + image base.
+
+* Base relocations (COFF)
+
+ Relocation information for the loader. If the loader decides to map
+ an executable or a DLL to a different address than their image
+ bases, it fixes up binaries using information contained in the base
+ relocation table. A base relocation table consists of a list of
+ locations containing addresses. The loader adds a difference between
+ RVA and actual load address to all locations listed there.
+
+ Note that this run-time relocation mechanism is much simpler than ELF.
+ There's no PLT or GOT. Images are relocated as a whole just
+ by shifting entire images in memory by some offsets. Although doing
+ this breaks text sharing, I think this mechanism is not actually bad
+ on today's computers.
+
+* ICF
+
+ Short for Identical COMDAT Folding (COFF) or Identical Code Folding (ELF).
+
+ ICF is an optimization to reduce output size by merging read-only sections
+ by not only their names but by their contents. If two read-only sections
+ happen to have the same metadata, actual contents and relocations,
+ they are merged by ICF. It is known as an effective technique,
+ and it usually reduces C++ program's size by a few percent or more.
+
+ Note that this is not entirely sound optimization. C/C++ require
+ different functions have different addresses. If a program depends on
+ that property, it would fail at runtime.
+
+ On Windows, that's not really an issue because MSVC link.exe enabled
+ the optimization by default. As long as your program works
+ with the linker's default settings, your program should be safe with ICF.
+
+ On Unix, your program is generally not guaranteed to be safe with ICF,
+ although large programs happen to work correctly.
+ LLD works fine with ICF for example.

+Windows support
+===============
+
+LLD supports Windows operating system. When invoked as ``lld-link.exe`` or with
+``-flavor link``, the driver for Windows operating system is used to parse
+command line options, and it drives further linking processes. LLD accepts
+almost all command line options that the linker shipped with Microsoft Visual
+C++ (link.exe) supports.
+
+The current status is that LLD can link itself on Windows x86/x64
+using Visual C++ 2013 as the compiler.
+
+Development status
+==================
+
+Driver
+ :good:`Mostly done`. Some exotic command line options that are not usually
+ used for application develompent, such as ``/DRIVER``, are not supported.
+ Options for Windows 8 app store are not recognized too
+ (e.g. ``/APPCONTAINER``).
+
+Linking against DLL
+ :good:`Done`. LLD can read import libraries needed to link against DLL. Both
+ export-by-name and export-by-ordinal are supported.
+
+Linking against static library
+ :good:`Done`. The format of static library (.lib) on Windows is actually the
+ same as on Unix (.a). LLD can read it.
+
+Creating DLL
+ :good:`Done`. LLD creates a DLL if ``/DLL`` option is given. Exported
+ functions can be specified either via command line (``/EXPORT``) or via
+ module-definition file (.def). Both export-by-name and export-by-ordinal are
+ supported. LLD uses Microsoft ``lib.exe`` tool to create an import library
+ file.
+
+Windows resource files support
+ :good:`Done`. If an ``.rc`` file is given, LLD converts the file to a COFF
+ file using some external commands and link it. Specifically, ``rc.exe`` is
+ used to compile a resource file (.rc) to a compiled resource (.res)
+ file. ``rescvt.exe`` is then used to convert a compiled resource file to a
+ COFF object file section. Both tools are shipped with MSVC.
+
+Safe Structured Exception Handler (SEH)
+ :good:`Done` for both x86 and x64.
+
+Module-definition file
+ :partial:`Partially done`. LLD currently recognizes these directives:
+ ``EXPORTS``, ``HEAPSIZE``, ``STACKSIZE``, ``NAME``, and ``VERSION``.
+
+Debug info
+ :none:`No progress has been made`. Microsoft linker can interpret the CodeGen
+ debug info (old-style debug info) and PDB to emit an .pdb file. LLD doesn't
+ support neither.
+
+
+Building LLD
+============
+
+Using Visual Studio IDE/MSBuild
+-------------------------------
+
+1. Check out LLVM and LLD from the LLVM SVN repository (or Git mirror),
+#. run ``cmake -G "Visual Studio 12" <llvm-source-dir>`` from VS command prompt,
+#. open LLVM.sln with Visual Studio, and
+#. build ``lld`` target in ``lld executables`` folder
+
+Alternatively, you can use msbuild if you don't like to work in an IDE::
+
+ msbuild LLVM.sln /m /target:"lld executables\lld"
+
+MSBuild.exe had been shipped as a component of the .NET framework, but since
+2013 it's part of Visual Studio. You can find it at "C:\\Program Files
+(x86)\\msbuild".
+
+You can build LLD as a 64 bit application. To do that, open VS2013 x64 command
+prompt and run cmake for "Visual Studio 12 Win64" target.
+
+Using Ninja
+-----------
+
+1. Check out LLVM and LLD from the LLVM SVN repository (or Git mirror),
+#. run ``cmake -G ninja <llvm-source-dir>`` from VS command prompt,
+#. run ``ninja lld``

+ATOM-based lld
+==============
+
+ATOM-based lld is a new set of modular code for creating linker tools.
+Currently it supports Mach-O.
+
+* End-User Features:
+
+ * Compatible with existing linker options
+ * Reads standard Object Files
+ * Writes standard Executable Files
+ * Remove clang's reliance on "the system linker"
+ * Uses the LLVM `"UIUC" BSD-Style license`__.
+
+* Applications:
+
+ * Modular design
+ * Support cross linking
+ * Easy to add new CPU support
+ * Can be built as static tool or library
+
+* Design and Implementation:
+
+ * Extensive unit tests
+ * Internal linker model can be dumped/read to textual format
+ * Additional linking features can be plugged in as "passes"
+ * OS specific and CPU specific code factored out
+
+Why a new linker?
+-----------------
+
+The fact that clang relies on whatever linker tool you happen to have installed
+means that clang has been very conservative adopting features which require a
+recent linker.
+
+In the same way that the MC layer of LLVM has removed clang's reliance on the
+system assembler tool, the lld project will remove clang's reliance on the
+system linker tool.

+Linker Design
+=============
+
+Introduction
+------------
+
+lld is a new generation of linker. It is not "section" based like traditional
+linkers which mostly just interlace sections from multiple object files into the
+output file. Instead, lld is based on "Atoms". Traditional section based
+linking work well for simple linking, but their model makes advanced linking
+features difficult to implement. Features like dead code stripping, reordering
+functions for locality, and C++ coalescing require the linker to work at a finer
+grain.
+
+An atom is an indivisible chunk of code or data. An atom has a set of
+attributes, such as: name, scope, content-type, alignment, etc. An atom also
+has a list of References. A Reference contains: a kind, an optional offset, an
+optional addend, and an optional target atom.
+
+The Atom model allows the linker to use standard graph theory models for linking
+data structures. Each atom is a node, and each Reference is an edge. The
+feature of dead code stripping is implemented by following edges to mark all
+live atoms, and then delete the non-live atoms.
+
+
+Atom Model
+----------
+
+An atom is an indivisible chunk of code or data. Typically each user written
+function or global variable is an atom. In addition, the compiler may emit
+other atoms, such as for literal c-strings or floating point constants, or for
+runtime data structures like dwarf unwind info or pointers to initializers.
+
+A simple "hello world" object file would be modeled like this:
+
+.. image:: hello.png
+
+There are three atoms: main, a proxy for printf, and an anonymous atom
+containing the c-string literal "hello world". The Atom "main" has two
+references. One is the call site for the call to printf, and the other is a
+reference for the instruction that loads the address of the c-string literal.
+
+There are only four different types of atoms:
+
+ * DefinedAtom
+ 95% of all atoms. This is a chunk of code or data
+
+ * UndefinedAtom
+ This is a place holder in object files for a reference to some atom
+ outside the translation unit.During core linking it is usually replaced
+ by (coalesced into) another Atom.
+
+ * SharedLibraryAtom
+ If a required symbol name turns out to be defined in a dynamic shared
+ library (and not some object file). A SharedLibraryAtom is the
+ placeholder Atom used to represent that fact.
+
+ It is similar to an UndefinedAtom, but it also tracks information
+ about the associated shared library.
+
+ * AbsoluteAtom
+ This is for embedded support where some stuff is implemented in ROM at
+ some fixed address. This atom has no content. It is just an address
+ that the Writer needs to fix up any references to point to.
+
+
+File Model
+----------
+
+The linker views the input files as basically containers of Atoms and
+References, and just a few attributes of their own. The linker works with three
+kinds of files: object files, static libraries, and dynamic shared libraries.
+Each kind of file has reader object which presents the file in the model
+expected by the linker.
+
+Object File
+~~~~~~~~~~~
+
+An object file is just a container of atoms. When linking an object file, a
+reader is instantiated which parses the object file and instantiates a set of
+atoms representing all content in the .o file. The linker adds all those atoms
+to a master graph.
+
+Static Library (Archive)
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+This is the traditional unix static archive which is just a collection of object
+files with a "table of contents". When linking with a static library, by default
+nothing is added to the master graph of atoms. Instead, if after merging all
+atoms from object files into a master graph, if any "undefined" atoms are left
+remaining in the master graph, the linker reads the table of contents for each
+static library to see if any have the needed definitions. If so, the set of
+atoms from the specified object file in the static library is added to the
+master graph of atoms.
+
+Dynamic Library (Shared Object)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Dynamic libraries are different than object files and static libraries in that
+they don't directly add any content. Their purpose is to check at build time
+that the remaining undefined references can be resolved at runtime, and provide
+a list of dynamic libraries (SO_NEEDED) that will be needed at runtime. The way
+this is modeled in the linker is that a dynamic library contributes no atoms to
+the initial graph of atoms. Instead, (like static libraries) if there are
+"undefined" atoms in the master graph of all atoms, then each dynamic library is
+checked to see if exports the required symbol. If so, a "shared library" atom is
+instantiated by the by the reader which the linker uses to replace the
+"undefined" atom.
+
+Linking Steps
+-------------
+
+Through the use of abstract Atoms, the core of linking is architecture
+independent and file format independent. All command line parsing is factored
+out into a separate "options" abstraction which enables the linker to be driven
+with different command line sets.
+
+The overall steps in linking are:
+
+ #. Command line processing
+
+ #. Parsing input files
+
+ #. Resolving
+
+ #. Passes/Optimizations
+
+ #. Generate output file
+
+The Resolving and Passes steps are done purely on the master graph of atoms, so
+they have no notion of file formats such as mach-o or ELF.
+
+
+Input Files
+~~~~~~~~~~~
+
+Existing developer tools using different file formats for object files.
+A goal of lld is to be file format independent. This is done
+through a plug-in model for reading object files. The lld::Reader is the base
+class for all object file readers. A Reader follows the factory method pattern.
+A Reader instantiates an lld::File object (which is a graph of Atoms) from a
+given object file (on disk or in-memory).
+
+Every Reader subclass defines its own "options" class (for instance the mach-o
+Reader defines the class ReaderOptionsMachO). This options class is the
+one-and-only way to control how the Reader operates when parsing an input file
+into an Atom graph. For instance, you may want the Reader to only accept
+certain architectures. The options class can be instantiated from command
+line options, or it can be subclassed and the ivars programmatically set.
+
+Resolving
+~~~~~~~~~
+
+The resolving step takes all the atoms' graphs from each object file and
+combines them into one master object graph. Unfortunately, it is not as simple
+as appending the atom list from each file into one big list. There are many
+cases where atoms need to be coalesced. That is, two or more atoms need to be
+coalesced into one atom. This is necessary to support: C language "tentative
+definitions", C++ weak symbols for templates and inlines defined in headers,
+replacing undefined atoms with actual definition atoms, and for merging copies
+of constants like c-strings and floating point constants.
+
+The linker support coalescing by-name and by-content. By-name is used for
+tentative definitions and weak symbols. By-content is used for constant data
+that can be merged.
+
+The resolving process maintains some global linking "state", including a "symbol
+table" which is a map from llvm::StringRef to lld::Atom*. With these data
+structures, the linker iterates all atoms in all input files. For each atom, it
+checks if the atom is named and has a global or hidden scope. If so, the atom
+is added to the symbol table map. If there already is a matching atom in that
+table, that means the current atom needs to be coalesced with the found atom, or
+it is a multiple definition error.
+
+When all initial input file atoms have been processed by the resolver, a scan is
+made to see if there are any undefined atoms in the graph. If there are, the
+linker scans all libraries (both static and dynamic) looking for definitions to
+replace the undefined atoms. It is an error if any undefined atoms are left
+remaining.
+
+Dead code stripping (if requested) is done at the end of resolving. The linker
+does a simple mark-and-sweep. It starts with "root" atoms (like "main" in a main
+executable) and follows each references and marks each Atom that it visits as
+"live". When done, all atoms not marked "live" are removed.
+
+The result of the Resolving phase is the creation of an lld::File object. The
+goal is that the lld::File model is **the** internal representation
+throughout the linker. The file readers parse (mach-o, ELF, COFF) into an
+lld::File. The file writers (mach-o, ELF, COFF) taken an lld::File and produce
+their file kind, and every Pass only operates on an lld::File. This is not only
+a simpler, consistent model, but it enables the state of the linker to be dumped
+at any point in the link for testing purposes.
+
+
+Passes
+~~~~~~
+
+The Passes step is an open ended set of routines that each get a change to
+modify or enhance the current lld::File object. Some example Passes are:
+
+ * stub (PLT) generation
+
+ * GOT instantiation
+
+ * order_file optimization
+
+ * branch island generation
+
+ * branch shim generation
+
+ * Objective-C optimizations (Darwin specific)
+
+ * TLV instantiation (Darwin specific)
+
+ * DTrace probe processing (Darwin specific)
+
+ * compact unwind encoding (Darwin specific)
+
+
+Some of these passes are specific to Darwin's runtime environments. But many of
+the passes are applicable to any OS (such as generating branch island for out of
+range branch instructions).
+
+The general structure of a pass is to iterate through the atoms in the current
+lld::File object, inspecting each atom and doing something. For instance, the
+stub pass, looks for call sites to shared library atoms (e.g. call to printf).
+It then instantiates a "stub" atom (PLT entry) and a "lazy pointer" atom for
+each proxy atom needed, and these new atoms are added to the current lld::File
+object. Next, all the noted call sites to shared library atoms have their
+References altered to point to the stub atom instead of the shared library atom.
+
+
+Generate Output File
+~~~~~~~~~~~~~~~~~~~~
+
+Once the passes are done, the output file writer is given current lld::File
+object. The writer's job is to create the executable content file wrapper and
+place the content of the atoms into it.
+
+lld uses a plug-in model for writing output files. All concrete writers (e.g.
+ELF, mach-o, etc) are subclasses of the lld::Writer class.
+
+Unlike the Reader class which has just one method to instantiate an lld::File,
+the Writer class has multiple methods. The crucial method is to generate the
+output file, but there are also methods which allow the Writer to contribute
+Atoms to the resolver and specify passes to run.
+
+An example of contributing
+atoms is that if the Writer knows a main executable is being linked and such
+an executable requires a specially named entry point (e.g. "_main"), the Writer
+can add an UndefinedAtom with that special name to the resolver. This will
+cause the resolver to issue an error if that symbol is not defined.
+
+Sometimes a Writer supports lazily created symbols, such as names for the start
+of sections. To support this, the Writer can create a File object which vends
+no initial atoms, but does lazily supply atoms by name as needed.
+
+Every Writer subclass defines its own "options" class (for instance the mach-o
+Writer defines the class WriterOptionsMachO). This options class is the
+one-and-only way to control how the Writer operates when producing an output
+file from an Atom graph. For instance, you may want the Writer to optimize
+the output for certain OS versions, or strip local symbols, etc. The options
+class can be instantiated from command line options, or it can be subclassed
+and the ivars programmatically set.
+
+
+lld::File representations
+-------------------------
+
+Just as LLVM has three representations of its IR model, lld has two
+representations of its File/Atom/Reference model:
+
+ * In memory, abstract C++ classes (lld::Atom, lld::Reference, and lld::File).
+
+ * textual (in YAML)
+
+
+Textual representations in YAML
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In designing a textual format we want something easy for humans to read and easy
+for the linker to parse. Since an atom has lots of attributes most of which are
+usually just the default, we should define default values for every attribute so
+that those can be omitted from the text representation. Here is the atoms for a
+simple hello world program expressed in YAML::
+
+ target-triple: x86_64-apple-darwin11
+
+ atoms:
+ - name: _main
+ scope: global
+ type: code
+ content: [ 55, 48, 89, e5, 48, 8d, 3d, 00, 00, 00, 00, 30, c0, e8, 00, 00,
+ 00, 00, 31, c0, 5d, c3 ]
+ fixups:
+ - offset: 07
+ kind: pcrel32
+ target: 2
+ - offset: 0E
+ kind: call32
+ target: _fprintf
+
+ - type: c-string
+ content: [ 73, 5A, 00 ]
+
+ ...
+
+The biggest use for the textual format will be writing test cases. Writing test
+cases in C is problematic because the compiler may vary its output over time for
+its own optimization reasons which my inadvertently disable or break the linker
+feature trying to be tested. By writing test cases in the linkers own textual
+format, we can exactly specify every attribute of every atom and thus target
+specific linker logic.
+
+The textual/YAML format follows the ReaderWriter patterns used in lld. The lld
+library comes with the classes: ReaderYAML and WriterYAML.
+
+
+Testing
+-------
+
+The lld project contains a test suite which is being built up as new code is
+added to lld. All new lld functionality should have a tests added to the test
+suite. The test suite is `lit <http://llvm.org/cmds/lit.html/>`_ driven. Each
+test is a text file with comments telling lit how to run the test and check the
+result To facilitate testing, the lld project builds a tool called lld-core.
+This tool reads a YAML file (default from stdin), parses it into one or more
+lld::File objects in memory and then feeds those lld::File objects to the
+resolver phase.
+
+
+Resolver testing
+~~~~~~~~~~~~~~~~
+
+Basic testing is the "core linking" or resolving phase. That is where the
+linker merges object files. All test cases are written in YAML. One feature of
+YAML is that it allows multiple "documents" to be encoding in one YAML stream.
+That means one text file can appear to the linker as multiple .o files - the
+normal case for the linker.
+
+Here is a simple example of a core linking test case. It checks that an
+undefined atom from one file will be replaced by a definition from another
+file::
+
+ # RUN: lld-core %s | FileCheck %s
+
+ #
+ # Test that undefined atoms are replaced with defined atoms.
+ #
+
+ ---
+ atoms:
+ - name: foo
+ definition: undefined
+ ---
+ atoms:
+ - name: foo
+ scope: global
+ type: code
+ ...
+
+ # CHECK: name: foo
+ # CHECK: scope: global
+ # CHECK: type: code
+ # CHECK-NOT: name: foo
+ # CHECK: ...
+
+
+Passes testing
+~~~~~~~~~~~~~~
+
+Since Passes just operate on an lld::File object, the lld-core tool has the
+option to run a particular pass (after resolving). Thus, you can write a YAML
+test case with carefully crafted input to exercise areas of a Pass and the check
+the resulting lld::File object as represented in YAML.
+
+
+Design Issues
+-------------
+
+There are a number of open issues in the design of lld. The plan is to wait and
+make these design decisions when we need to.
+
+
+Debug Info
+~~~~~~~~~~
+
+Currently, the lld model says nothing about debug info. But the most popular
+debug format is DWARF and there is some impedance mismatch with the lld model
+and DWARF. In lld there are just Atoms and only Atoms that need to be in a
+special section at runtime have an associated section. Also, Atoms do not have
+addresses. The way DWARF is spec'ed different parts of DWARF are supposed to go
+into specially named sections and the DWARF references function code by address.
+
+CPU and OS specific functionality
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Currently, lld has an abstract "Platform" that deals with any CPU or OS specific
+differences in linking. We just keep adding virtual methods to the base
+Platform class as we find linking areas that might need customization. At some
+point we'll need to structure this better.
+
+
+File Attributes
+~~~~~~~~~~~~~~~
+
+Currently, lld::File just has a path and a way to iterate its atoms. We will
+need to add more attributes on a File. For example, some equivalent to the
+target triple. There is also a number of cached or computed attributes that
+could make various Passes more efficient. For instance, on Darwin there are a
+number of Objective-C optimizations that can be done by a Pass. But it would
+improve the plain C case if the Objective-C optimization Pass did not have to
+scan all atoms looking for any Objective-C data structures. This could be done
+if the lld::File object had an attribute that said if the file had any
+Objective-C data in it. The Resolving phase would then be required to "merge"
+that attribute as object files are added.

+.. _Readers:
+
+Developing lld Readers
+======================
+
+Introduction
+------------
+
+The purpose of a "Reader" is to take an object file in a particular format
+and create an `lld::File`:cpp:class: (which is a graph of Atoms)
+representing the object file. A Reader inherits from
+`lld::Reader`:cpp:class: which lives in
+:file:`include/lld/Core/Reader.h` and
+:file:`lib/Core/Reader.cpp`.
+
+The Reader infrastructure for an object format ``Foo`` requires the
+following pieces in order to fit into lld:
+
+:file:`include/lld/ReaderWriter/ReaderFoo.h`
+
+ .. cpp:class:: ReaderOptionsFoo : public ReaderOptions
+
+ This Options class is the only way to configure how the Reader will
+ parse any file into an `lld::Reader`:cpp:class: object. This class
+ should be declared in the `lld`:cpp:class: namespace.
+
+ .. cpp:function:: Reader *createReaderFoo(ReaderOptionsFoo &reader)
+
+ This factory function configures and create the Reader. This function
+ should be declared in the `lld`:cpp:class: namespace.
+
+:file:`lib/ReaderWriter/Foo/ReaderFoo.cpp`
+
+ .. cpp:class:: ReaderFoo : public Reader
+
+ This is the concrete Reader class which can be called to parse
+ object files. It should be declared in an anonymous namespace or
+ if there is shared code with the `lld::WriterFoo`:cpp:class: you
+ can make a nested namespace (e.g. `lld::foo`:cpp:class:).
+
+You may have noticed that :cpp:class:`ReaderFoo` is not declared in the
+``.h`` file. An important design aspect of lld is that all Readers are
+created *only* through an object-format-specific
+:cpp:func:`createReaderFoo` factory function. The creation of the Reader is
+parametrized through a :cpp:class:`ReaderOptionsFoo` class. This options
+class is the one-and-only way to control how the Reader operates when
+parsing an input file into an Atom graph. For instance, you may want the
+Reader to only accept certain architectures. The options class can be
+instantiated from command line options or be programmatically configured.
+
+Where to start
+--------------
+
+The lld project already has a skeleton of source code for Readers for
+``ELF``, ``PECOFF``, ``MachO``, and lld's native ``YAML`` graph format.
+If your file format is a variant of one of those, you should modify the
+existing Reader to support your variant. This is done by customizing the Options
+class for the Reader and making appropriate changes to the ``.cpp`` file to
+interpret those options and act accordingly.
+
+If your object file format is not a variant of any existing Reader, you'll need
+to create a new Reader subclass with the organization described above.
+
+Readers are factories
+---------------------
+
+The linker will usually only instantiate your Reader once. That one Reader will
+have its loadFile() method called many times with different input files.
+To support multithreaded linking, the Reader may be parsing multiple input
+files in parallel. Therefore, there should be no parsing state in you Reader
+object. Any parsing state should be in ivars of your File subclass or in
+some temporary object.
+
+The key method to implement in a reader is::
+
+ virtual error_code loadFile(LinkerInput &input,
+ std::vector<std::unique_ptr<File>> &result);
+
+It takes a memory buffer (which contains the contents of the object file
+being read) and returns an instantiated lld::File object which is
+a collection of Atoms. The result is a vector of File pointers (instead of
+simple a File pointer) because some file formats allow multiple object
+"files" to be encoded in one file system file.
+
+
+Memory Ownership
+----------------
+
+Atoms are always owned by their File object. During core linking when Atoms
+are coalesced or stripped away, core linking does not delete them.
+Core linking just removes those unused Atoms from its internal list.
+The destructor of a File object is responsible for deleting all Atoms it
+owns, and if ownership of the MemoryBuffer was passed to it, the File
+destructor needs to delete that too.
+
+Making Atoms
+------------
+
+The internal model of lld is purely Atom based. But most object files do not
+have an explicit concept of Atoms, instead most have "sections". The way
+to think of this is that a section is just a list of Atoms with common
+attributes.
+
+The first step in parsing section-based object files is to cleave each
+section into a list of Atoms. The technique may vary by section type. For
+code sections (e.g. .text), there are usually symbols at the start of each
+function. Those symbol addresses are the points at which the section is
+cleaved into discrete Atoms. Some file formats (like ELF) also include the
+length of each symbol in the symbol table. Otherwise, the length of each
+Atom is calculated to run to the start of the next symbol or the end of the
+section.
+
+Other sections types can be implicitly cleaved. For instance c-string literals
+or unwind info (e.g. .eh_frame) can be cleaved by having the Reader look at
+the content of the section. It is important to cleave sections into Atoms
+to remove false dependencies. For instance the .eh_frame section often
+has no symbols, but contains "pointers" to the functions for which it
+has unwind info. If the .eh_frame section was not cleaved (but left as one
+big Atom), there would always be a reference (from the eh_frame Atom) to
+each function. So the linker would be unable to coalesce or dead stripped
+away the function atoms.
+
+The lld Atom model also requires that a reference to an undefined symbol be
+modeled as a Reference to an UndefinedAtom. So the Reader also needs to
+create an UndefinedAtom for each undefined symbol in the object file.
+
+Once all Atoms have been created, the second step is to create References
+(recall that Atoms are "nodes" and References are "edges"). Most References
+are created by looking at the "relocation records" in the object file. If
+a function contains a call to "malloc", there is usually a relocation record
+specifying the address in the section and the symbol table index. Your
+Reader will need to convert the address to an Atom and offset and the symbol
+table index into a target Atom. If "malloc" is not defined in the object file,
+the target Atom of the Reference will be an UndefinedAtom.
+
+
+Performance
+-----------
+Once you have the above working to parse an object file into Atoms and
+References, you'll want to look at performance. Some techniques that can
+help performance are:
+
+* Use llvm::BumpPtrAllocator or pre-allocate one big vector<Reference> and then
+ just have each atom point to its subrange of References in that vector.
+ This can be faster that allocating each Reference as separate object.
+* Pre-scan the symbol table and determine how many atoms are in each section
+ then allocate space for all the Atom objects at once.
+* Don't copy symbol names or section content to each Atom, instead use
+ StringRef and ArrayRef in each Atom to point to its name and content in the
+ MemoryBuffer.
+
+
+Testing
+-------
+
+We are still working on infrastructure to test Readers. The issue is that
+you don't want to check in binary files to the test suite. And the tools
+for creating your object file from assembly source may not be available on
+every OS.
+
+We are investigating a way to use YAML to describe the section, symbols,
+and content of a file. Then have some code which will write out an object
+file from that YAML description.
+
+Once that is in place, you can write test cases that contain section/symbols
+YAML and is run through the linker to produce Atom/References based YAML which
+is then run through FileCheck to verify the Atoms and References are as
+expected.

+
+Sphinx Introduction for LLVM Developers
+=======================================
+
+This document is intended as a short and simple introduction to the Sphinx
+documentation generation system for LLVM developers.
+
+Quickstart
+----------
+
+To get started writing documentation, you will need to:
+
+ 1. Have the Sphinx tools :ref:`installed <installing_sphinx>`.
+
+ 2. Understand how to :ref:`build the documentation
+ <building_the_documentation>`.
+
+ 3. Start :ref:`writing documentation <writing_documentation>`!
+
+.. _installing_sphinx:
+
+Installing Sphinx
+~~~~~~~~~~~~~~~~~
+
+You should be able to install Sphinx using the standard Python package
+installation tool ``easy_install``, as follows::
+
+ $ sudo easy_install sphinx
+ Searching for sphinx
+ Reading http://pypi.python.org/simple/sphinx/
+ Reading http://sphinx.pocoo.org/
+ Best match: Sphinx 1.1.3
+ ... more lines here ..
+
+If you do not have root access (or otherwise want to avoid installing Sphinx in
+system directories) see the section on :ref:`installing_sphinx_in_a_venv` .
+
+If you do not have the ``easy_install`` tool on your system, you should be able
+to install it using:
+
+ Linux
+ Use your distribution's standard package management tool to install it,
+ i.e., ``apt-get install easy_install`` or ``yum install easy_install``.
+
+ Mac OS X
+ All modern Mac OS X systems come with ``easy_install`` as part of the base
+ system.
+
+ Windows
+ See the `setuptools <http://pypi.python.org/pypi/setuptools>`_ package web
+ page for instructions.
+
+
+.. _building_the_documentation:
+
+Building the documentation
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In order to build the documentation, all you should need to do is change to the
+``docs`` directory and invoke make as follows::
+
+ $ cd path/to/project/docs
+ $ make html
+
+Note that on Windows there is a ``make.bat`` command in the docs directory which
+supplies the same interface as the ``Makefile``.
+
+That command will invoke ``sphinx-build`` with the appropriate options for the
+project, and generate the HTML documentation in a ``_build`` subdirectory. You
+can browse it starting from the index page by visiting
+``_build/html/index.html``.
+
+Sphinx supports a wide variety of generation formats (including LaTeX, man
+pages, and plain text). The ``Makefile`` includes a number of convenience
+targets for invoking ``sphinx-build`` appropriately, the common ones are:
+
+ make html
+ Generate the HTML output.
+
+ make latexpdf
+ Generate LaTeX documentation and convert to a PDF.
+
+ make man
+ Generate man pages.
+
+
+.. _writing_documentation:
+
+Writing documentation
+~~~~~~~~~~~~~~~~~~~~~
+
+The documentation itself is written in the reStructuredText (ReST) format, and Sphinx
+defines additional tags to support features like cross-referencing.
+
+The ReST format itself is organized around documents mostly being readable
+plaintext documents. You should generally be able to write new documentation
+easily just by following the style of the existing documentation.
+
+If you want to understand the formatting of the documents more, the best place
+to start is Sphinx's own `ReST Primer <http://sphinx.pocoo.org/rest.html>`_.
+
+
+Learning More
+-------------
+
+If you want to learn more about the Sphinx system, the best place to start is
+the Sphinx documentation itself, available `here
+<http://sphinx.pocoo.org/contents.html>`_.
+
+
+.. _installing_sphinx_in_a_venv:
+
+Installing Sphinx in a Virtual Environment
+------------------------------------------
+
+Most Python developers prefer to work with tools inside a *virtualenv* (virtual
+environment) instance, which functions as an application sandbox. This avoids
+polluting your system installation with different packages used by various
+projects (and ensures that dependencies for different packages don't conflict
+with one another). Of course, you need to first have the virtualenv software
+itself which generally would be installed at the system level::
+
+ $ sudo easy_install virtualenv
+
+but after that you no longer need to install additional packages in the system
+directories.
+
+Once you have the *virtualenv* tool itself installed, you can create a
+virtualenv for Sphinx using::
+
+ $ virtualenv ~/my-sphinx-install
+ New python executable in /Users/dummy/my-sphinx-install/bin/python
+ Installing setuptools............done.
+ Installing pip...............done.
+
+ $ ~/my-sphinx-install/bin/easy_install sphinx
+ ... install messages here ...
+
+and from now on you can "activate" the *virtualenv* using::
+
+ $ source ~/my-sphinx-install/bin/activate
+
+which will change your PATH to ensure the sphinx-build tool from inside the
+virtual environment will be used. See the `virtualenv website
+<http://www.virtualenv.org/en/latest/index.html>`_ for more information on using
+virtual environments.

+// License. See LICENSE.TXT for details.
+//
+//===----------------------------------------------------------------------===//
+//
+// This file contains platform-independent functions to process relocations.
+// I'll describe the overview of this file here.
+//
+// Simple relocations are easy to handle for the linker. For example,
+// for R_X86_64_PC64 relocs, the linker just has to fix up locations
+// with the relative offsets to the target symbols. It would just be
+// reading records from relocation sections and applying them to output.
+//
+// But not all relocations are that easy to handle. For example, for
+// R_386_GOTOFF relocs, the linker has to create new GOT entries for
+// symbols if they don't exist, and fix up locations with GOT entry
+// offsets from the beginning of GOT section. So there is more than
+// fixing addresses in relocation processing.
+//
+// ELF defines a large number of complex relocations.
+//
+// The functions in this file analyze relocations and do whatever needs
+// to be done. It includes, but not limited to, the following.
+//
+// - create GOT/PLT entries
+// - create new relocations in .dynsym to let the dynamic linker resolve
+// them at runtime (since ELF supports dynamic linking, not all
+// relocations can be resolved at link-time)
+// - create COPY relocs and reserve space in .bss
+// - replace expensive relocs (in terms of runtime cost) with cheap ones
+// - error out infeasible combinations such as PIC and non-relative relocs
+//
+// Note that the functions in this file don't actually apply relocations
+// because it doesn't know about the output file nor the output file buffer.
+// It instead stores Relocation objects to InputSection's Relocations
+// vector to let it apply later in InputSection::writeTo.

+// File contains classes for implementation of --gdb-index command line option.
+//
+// If that option is used, linker should emit a .gdb_index section that allows
+// debugger to locate and read .dwo files, containing neccessary debug
+// information.
+// More information about implementation can be found in DWARF specification,
+// latest version is available at http://dwarfstd.org.
+//
+// .gdb_index section format:
+// (Information is based on/taken from
+// https://sourceware.org/gdb/onlinedocs/gdb/Index-Section-Format.html (*))
+//
+// A mapped index consists of several areas, laid out in order:
+// 1) The file header.
+// 2) "The CU (compilation unit) list. This is a sequence of pairs of 64-bit
+// little-endian values, sorted by the CU offset. The first element in each
+// pair is the offset of a CU in the .debug_info section. The second element
+// in each pair is the length of that CU. References to a CU elsewhere in the
+// map are done using a CU index, which is just the 0-based index into this
+// table. Note that if there are type CUs, then conceptually CUs and type CUs
+// form a single list for the purposes of CU indices."(*)
+// 3) The types CU list. Depricated as .debug_types does not appear in the DWARF
+// v5 specification.
+// 4) The address area. The address area is a sequence of address
+// entries, where each entrie contains low address, high address and CU
+// index.
+// 5) "The symbol table. This is an open-addressed hash table. The size of the
+// hash table is always a power of 2. Each slot in the hash table consists of
+// a pair of offset_type values. The first value is the offset of the
+// symbol's name in the constant pool. The second value is the offset of the
+// CU vector in the constant pool."(*)
+// 6) "The constant pool. This is simply a bunch of bytes. It is organized so
+// that alignment is correct: CU vectors are stored first, followed by
+// strings." (*)
+//
+// For constructing the .gdb_index section following steps should be performed:
+// 1) For file header nothing special should be done. It contains the offsets to
+// the areas below.
+// 2) Scan the compilation unit headers of the .debug_info sections to build a
+// list of compilation units.
+// 3) CU Types are no longer needed as DWARF skeleton type units never made it
+// into the standard. lld does nothing to support parsing of .debug_types
+// and generates empty types CU area in .gdb_index section.
+// 4) Address area entries are extracted from DW_TAG_compile_unit DIEs of
+// .debug_info sections.
+// 5) For building the symbol table linker extracts the public names from the
+// .debug_gnu_pubnames and .debug_gnu_pubtypes sections. Then it builds the
+// hashtable in according to .gdb_index format specification.
+// 6) Constant pool is populated at the same time as symbol table.

+// ICF is short for Identical Code Folding. This is a size optimization to

+//
+// In ICF, two sections are considered identical if they have the same

+// because two relocations are considered the same if they have the same
+// relocation types, values, and if they point to the same sections *in
+// terms of ICF*.
+//
+// Here is an example. If foo and bar defined below are compiled to the
+// same machine instructions, ICF can and should merge the two, although
+// their relocations point to each other.
+//
+// void foo() { bar(); }
+// void bar() { foo(); }
+//
+// If you merge the two, their relocations point to the same section and
+// thus you know they are mergeable, but how do you know they are
+// mergeable in the first place? This is not an easy problem to solve.

+// What we are doing in LLD is to partition sections into equivalence
+// classes. Sections in the same equivalence class when the algorithm
+// terminates are considered identical. Here are details:
+//
+// 1. First, we partition sections using their hash values as keys. Hash
+// values contain section types, section contents and numbers of
+// relocations. During this step, relocation targets are not taken into
+// account. We just put sections that apparently differ into different
+// equivalence classes.
+//
+// 2. Next, for each equivalence class, we visit sections to compare
+// relocation targets. Relocation targets are considered equivalent if
+// their targets are in the same equivalence class. Sections with
+// different relocation targets are put into different equivalence
+// clases.
+//
+// 3. If we split an equivalence class in step 2, two relocations
+// previously target the same equivalence class may now target
+// different equivalence classes. Therefore, we repeat step 2 until a
+// convergence is obtained.
+//
+// 4. For each equivalence class C, pick an arbitrary section in C, and
+// merge all the other sections in C with it.
+//
+// For small programs, this algorithm needs 3-5 iterations. For large
+// programs such as Chromium, it takes more than 20 iterations.
+//
+// This algorithm was mentioned as an "optimistic algorithm" in [1],
+// though gold implements a different algorithm than this.
+//
+// We parallelize each step so that multiple threads can work on different
+// equivalence classes concurrently. That gave us a large performance
+// boost when applying ICF on large programs. For example, MSVC link.exe
+// or GNU gold takes 10-20 seconds to apply ICF on Chromium, whose output
+// size is about 1.5 GB, but LLD can finish it in less than 2 seconds on a
+// 2.8 GHz 40 core machine. Even without threading, LLD's ICF is still
+// faster than MSVC or gold though.

+// sections from output. Unused sections are sections that are not reachable
+// from known GC-root symbols or sections. Naturally the feature is
+// implemented as a mark-sweep garbage collector.
+//
+// Here's how it works. Each InputSectionBase has a "Live" bit. The bit is off
+// by default. Starting with GC-root symbols or sections, markLive function
+// defined in this file visits all reachable sections to set their Live
+// bits. Writer will then ignore sections whose Live bits are off, so that
+// such sections are not included into output.

+//
+// LLD supports threads to distribute workloads to multiple cores. Using
+// multicore is most effective when more than one core are idle. At the
+// last step of a build, it is often the case that a linker is the only
+// active process on a computer. So, we are naturally interested in using
+// threads wisely to reduce latency to deliver results to users.
+//
+// That said, we don't want to do "too clever" things using threads.
+// Complex multi-threaded algorithms are sometimes extremely hard to
+// justify the correctness and can easily mess up the entire design.
+//
+// Fortunately, when a linker links large programs (when the link time is
+// most critical), it spends most of the time to work on massive number of
+// small pieces of data of the same kind, and there are opportunities for
+// large parallelism there. Here are examples:
+//
+// - We have hundreds of thousands of input sections that need to be
+// copied to a result file at the last step of link. Once we fix a file
+// layout, each section can be copied to its destination and its
+// relocations can be applied independently.
+//
+// - We have tens of millions of small strings when constructing a
+// mergeable string section.
+//
+// For the cases such as the former, we can just use parallel_for_each
+// instead of std::for_each (or a plain for loop). Because tasks are
+// completely independent from each other, we can run them in parallel
+// without any coordination between them. That's very easy to understand
+// and justify.
+//
+// For the cases such as the latter, we can use parallel algorithms to
+// deal with massive data. We have to write code for a tailored algorithm
+// for each problem, but the complexity of multi-threading is isolated in
+// a single pass and doesn't affect the linker's overall design.
+//
+// The above approach seems to be working fairly well. As an example, when
+// linking Chromium (output size 1.6 GB), using 4 cores reduces latency to
+// 75% compared to single core (from 12.66 seconds to 9.55 seconds) on my
+// Ivy Bridge Xeon 2.8 GHz machine. Using 40 cores reduces it to 63% (from
+// 12.66 seconds to 7.95 seconds). Because of the Amdahl's law, the
+// speedup is not linear, but as you add more cores, it gets faster.
+//
+// On a final note, if you are trying to optimize, keep the axiom "don't
+// guess, measure!" in mind. Some important passes of the linker are not
+// that slow. For example, resolving all symbols is not a very heavy pass,
+// although it would be very hard to parallelize it. You want to first
+// identify a slow pass and then optimize it.

+# This test shows an oddity in lld. When a linker script alternates among
+# different types of output section in the same command, the sections are
+# reordered.
+# In this test we go from regular, to merge and back to regular. The reason
+# for the reordering is that we need two create two output sections and
+# one cannot be in the middle of another.
+# If this ever becomes a problem, some options would be:
+# * Adding an extra layer in between input section and output sections (Chunk).
+# With that this example would have 3 chunks, but only one output section.
+# This would unfortunately complicate the non-script case too.
+# * Just create three output sections.
+# * If having three output sections causes problem, have linkerscript specific
+# code to write the section table and section indexes. That way we could
+# keep 3 sections internally but not expose that.

+/// This linker pass transforms all GOT kind references to real references.
+/// That is, in assembly you can write something like:
+/// movq foo@GOTPCREL(%rip), %rax
+/// which means you want to load a pointer to "foo" out of the GOT (global
+/// Offsets Table). In the object file, the Atom containing this instruction
+/// has a Reference whose target is an Atom named "foo" and the Reference
+/// kind is a GOT load. The linker needs to instantiate a pointer sized
+/// GOT entry. This is done be creating a GOT Atom to represent that pointer
+/// sized data in this pass, and altering the Atom graph so the Reference now
+/// points to the GOT Atom entry (corresponding to "foo") and changing the
+/// Reference Kind to reflect it is now pointing to a GOT entry (rather
+/// then needing a GOT entry).
+///
+/// There is one optimization the linker can do here. If the target of the GOT

+// This linker pass updates branch-sites whose target is a different mode
+// (thumb vs arm).
+//
+// Arm code has two instruction encodings thumb and arm. When branching from
+// one code encoding to another, you need to use an instruction that switches
+// the instruction mode. Usually the transition only happens at call sites, and
+// the linker can transform a BL instruction in BLX (or vice versa). But if the
+// compiler did a tail call optimization and a function ends with a branch (not
+// branch and link), there is no pc-rel BX instruction.
+//
+// The ShimPass looks for pc-rel B instructions that will need to switch mode.
+// For those cases it synthesizes a shim which does the transition, then
+// modifies the original atom with the B instruction to target to the shim atom.
