Regarding powerpc bootstraps: on 13.1 rust builds fine without bfd. Would it be possible to build bootstraps against 13.1 for powerpc?

[pkubaj]

Use the following patch for powerpc (assuming 13.1):

That makes lang/rust build.
For lang/rust-bootstrap, you will probably also need changing /usr/local/freebsd-sysroot/powerpc/bin/c* (remove -fuse-ld="/usr/local/bin/powerpc-unknown-freebsd13.0-ld.bfd). Since the system compiler is used, build on 13.1

The problem with devel/racer is as follows:

• racer 2.1.48 doesn't build with rust 1.60.0
• racer 2.x requires rustc-dev from rust-nightly
• rustc-dev is not "fabricated" on lang/rust-nightly because we use x.py build instead of x.py dist

Probably time to resurrect https://reviews.freebsd.org/D28520

Racer 2.2.0 builds fine with rust 1.60.0 and rustc-dev (no need for the nightly version)

@mikael
I'm not sure what happened, but I can now build lang/rust-bootstrap@powerpc without additional patching. Do you want me to upload the bootstrap somewhere?

devel/racer has always been a problem. Let's remove it or if it builds now put an expiration date on it. People can build it themselves with cargo install or use rls or better rust-analyzer like upstream suggests anyway.

Using x.py dist starts making a whole lot of sense if FreeBSD Ports ever gets the long overdue support for generating subpackages. Every distfile is a natural subpackage.

Please let me know if you want me to test something for this update.

We should only have one of those. Remove mine. I'm going to ask clusteradm if we can have a /home/rust on freefall. Other groups also have one.

[mikael]

Here is an update. I still have to test a few things marked with XXX in the Makefile.
The DOC doesn't build but there is a patch available now, we should try to import it.
I'm still not sure if we should install rustc-dev on the stable channel (alpine installs it), it's only usefull to build devel/racer. It adds 120MB to rust-1.60.0.pkg

• Switch to using x.py dist instead of x.py in the do-build phase as we are missing the rustc-dev component (needed for devel/racer)
• Revert part of [1] as it causes cross build problem with lang/rust-bootstrap@powerpc

Just LOCAL/rust

This reenables rls on powerpc but it's excluded just above.

126–127

Should it use ${_PACKAGE_VERS} too?

134–136

Options helpers?

WASM_VARS=      _COMPONENTS+="rust-analysis-${_PACKAGE_VERS}-wasm32-unknown-unknown rust-std-${_PACKAGE_VERS}-wasm32-unknown-unknown"

[mikael]

• Mark devel/racer as broken and set an expiration date
• Only build rustc-dev on nightly (per https://rust-lang.github.io/rustup/concepts/components.html)

@jbeich @cmt gecko Rust 1.60.0 bundles LLVM 14 now. Please advise if there's anything that needs to happen for Gecko ports because of it.

It's missing DEPRECATED. I think we should point people to rust-analyzer in DEPRECATED.

Mk/bsd.gecko.mk

• Since 6ec985b72d58 bump local LLVM_DEFAULT in Mk/bsd.gecko.mk to match LLVM major version in lang/rust. Required at least by LLD to understand the new bytecode emitted by Rust compiler.
• Since f4c07f1834f7 create devel/wasi-compiler-rt* matching LLVM major version used by clang* (via LLVM_DEFAULT) and probably rustc (via wasm32-wasi target) then bump LLVM_VERSION in Mk/bsd.gecko.mk. See also WASM sandboxing, bug 260134, powerpc64 workaround (i.e. --without-wasm-sandboxed-libraries).

Firefox upstream upgraded both Rust to 1.60 and Clang to 14, see https://bugzilla.mozilla.org/show_bug.cgi?id=1758780

[cmt]

Not to be the party pooper here, but as of now devel/llvm14 doesn't even build with default options on 13.0 (I think brooks@'s rererevert of the libunwind dependency logic broke it, at least the error matches). Once that's sorted out, I can take care of the wasi-compiler-stuff. Totally excited about having a fourth llvm installation besides base.
