If "\-" is specified for the +input file, the input is read from the program\(aqs standard input stream. +.sp +If the input is an archive, any requested operations will be applied to each +archive member individually. +.sp +The tool is still in active development, but in most scenarios it works as a +drop\-in replacement for GNU\(aqs \fBstrip\fP\&. +.SH GENERIC AND CROSS-PLATFORM OPTIONS +.sp +The following options are either agnostic of the file format, or apply to +multiple file formats. +.INDENT 0.0 +.TP +.B \-\-disable\-deterministic\-archives, \-U +Use real values for UIDs, GIDs and timestamps when updating archive member +headers. +.UNINDENT +.INDENT 0.0 +.TP +.B \-\-discard\-all, \-x +Remove most local symbols from the output. Different file formats may limit +this to a subset of the local symbols. For example, file and section symbols in +ELF objects will not be discarded. Additionally, remove all debug sections. +.UNINDENT +.INDENT 0.0 +.TP +.B \-\-enable\-deterministic\-archives, \-D +Enable deterministic mode when stripping archives, i.e. use 0 for archive member +header UIDs, GIDs and timestamp fields. On by default. +.UNINDENT +.INDENT 0.0 +.TP +.B \-\-help, \-h +Print a summary of command line options. +.UNINDENT +.INDENT 0.0 +.TP +.B \-\-no\-strip\-all +Disable \fI\%\-\-strip\-all\fP\&. +.UNINDENT +.INDENT 0.0 +.TP +.B \-o +Write output to . Multiple input files cannot be used in combination +with \-o. +.UNINDENT +.INDENT 0.0 +.TP +.B \-\-regex +If specified, symbol and section names specified by other switches are treated +as extended POSIX regular expression patterns. +.UNINDENT +.INDENT 0.0 +.TP +.B \-\-remove\-section
, \-R +Remove the specified section from the output. Can be specified multiple times +to remove multiple sections simultaneously. +.UNINDENT +.INDENT 0.0 +.TP +.B \-\-strip\-all\-gnu +Remove all symbols, debug sections and relocations from the output. This option +is equivalent to GNU \fBstrip\fP\(aqs \fB\-\-strip\-all\fP switch. +.UNINDENT +.INDENT 0.0 +.TP +.B \-\-strip\-all, \-s +For ELF objects, remove from the output all symbols and non\-alloc sections not +within segments, except for .gnu.warning, .ARM.attribute sections and the +section name table. +.sp +For COFF objects, remove all symbols, debug sections, and relocations from the +output. +.UNINDENT +.INDENT 0.0 +.TP +.B \-\-strip\-debug, \-d, \-g, \-S +Remove all debug sections from the output. +.UNINDENT +.INDENT 0.0 +.TP +.B \-\-strip\-symbol , \-N +Remove all symbols named \fB\fP from the output. Can be specified +multiple times to remove multiple symbols. +.UNINDENT +.INDENT 0.0 +.TP +.B \-\-strip\-unneeded +Remove from the output all local or undefined symbols that are not required by +relocations. Also remove all debug sections. +.UNINDENT +.INDENT 0.0 +.TP +.B \-\-version, \-V +Display the version of the \fBllvm\-strip\fP executable. +.UNINDENT +.INDENT 0.0 +.TP +.B \-\-wildcard, \-w +Allow wildcard syntax for symbol\-related flags. On by default for +section\-related flags. Incompatible with \-\-regex. +.sp +Wildcard syntax allows the following special symbols: +.TS +center; +|l|l|l|. +_ +T{ +Character +T} T{ +Meaning +T} T{ +Equivalent +T} +_ +T{ +\fB*\fP +T} T{ +Any number of characters +T} T{ +\fB\&.*\fP +T} +_ +T{ +\fB?\fP +T} T{ +Any single character +T} T{ +\fB\&.\fP +T} +_ +T{ +\fB\e\fP +T} T{ +Escape the next character +T} T{ +\fB\e\fP +T} +_ +T{ +\fB[a\-z]\fP +T} T{ +Character class +T} T{ +\fB[a\-z]\fP +T} +_ +T{ +\fB[!a\-z]\fP, \fB[^a\-z]\fP +T} T{ +Negated character class +T} T{ +\fB[^a\-z]\fP +T} +_ +.TE +.sp +Additionally, starting a wildcard with \(aq!\(aq will prevent a match, even if +another flag matches. For example \fB\-w \-N \(aq*\(aq \-N \(aq!x\(aq\fP will strip all symbols +except for \fBx\fP\&. +.sp +The order of wildcards does not matter. For example, \fB\-w \-N \(aq*\(aq \-N \(aq!x\(aq\fP is +the same as \fB\-w \-N \(aq!x\(aq \-N \(aq*\(aq\fP\&. +.UNINDENT +.INDENT 0.0 +.TP +.B @ +Read command\-line options and commands from response file \fI\fP\&. +.UNINDENT +.SH COFF-SPECIFIC OPTIONS +.sp +The following options are implemented only for COFF objects.
