LLVM-STRIP(1) LLVM LLVM-STRIP(1) NAME llvm-strip - object stripping tool SYNOPSIS llvm-strip [options] inputs... DESCRIPTION llvm-strip is a tool to strip sections and symbols from object files. If no other stripping or remove options are specified, --strip-all will be en- abled. By default, the input files are modified in-place. If "-" is specified for the input file, the input is read from the program's standard input stream. If the input is an archive, any requested operations will be applied to each archive member individually. The tool is still in active development, but in most scenarios it works as a drop-in replacement for GNU's strip. GENERIC AND CROSS-PLATFORM OPTIONS The following options are either agnostic of the file format, or apply to multiple file formats. --disable-deterministic-archives, -U Use real values for UIDs, GIDs and timestamps when updating archive member headers. --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. Addition- ally, remove all debug sections. --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 de- fault. --help, -h Print a summary of command line options. --no-strip-all Disable --strip-all. -o <file> Write output to <file>. Multiple input files cannot be used in com- bination with -o. --only-keep-debug Produce a debug file as the output that only preserves contents of sections useful for debugging purposes. For ELF objects, this removes the contents of SHF_ALLOC sections that are not SHT_NOTE by making them SHT_NOBITS and shrinking the program headers where possible. --regex If specified, symbol and section names specified by other switches are treated as extended POSIX regular expression patterns. --remove-section <section>, -R Remove the specified section from the output. Can be specified mul- tiple times to remove multiple sections simultaneously. --strip-all-gnu Remove all symbols, debug sections and relocations from the output. This option is equivalent to GNU strip's --strip-all switch. --strip-all, -s For ELF objects, remove from the output all symbols and non-alloc sections not within segments, except for .gnu.warning, .ARM.at- tribute sections and the section name table. For COFF objects, remove all symbols, debug sections, and reloca- tions from the output. --strip-debug, -d, -g, -S Remove all debug sections from the output. --strip-symbol <symbol>, -N Remove all symbols named <symbol> from the output. Can be specified multiple times to remove multiple symbols. --strip-unneeded Remove from the output all local or undefined symbols that are not required by relocations. Also remove all debug sections. --version, -V Display the version of the llvm-strip executable. --wildcard, -w Allow wildcard syntax for symbol-related flags. On by default for section-related flags. Incompatible with --regex. Wildcard syntax allows the following special symbols: +----------------+----------------------+------------+ | Character | Meaning | Equivalent | +----------------+----------------------+------------+ | * | Any number of char- | .* | | | acters | | +----------------+----------------------+------------+ | ? | Any single character | . | +----------------+----------------------+------------+ | \ | Escape the next | \ | | | character | | +----------------+----------------------+------------+ | [a-z] | Character class | [a-z] | +----------------+----------------------+------------+ | [!a-z], [^a-z] | Negated character | [^a-z] | | | class | | +----------------+----------------------+------------+ Additionally, starting a wildcard with '!' will prevent a match, even if another flag matches. For example -w -N '*' -N '!x' will strip all symbols except for x. The order of wildcards does not matter. For example, -w -N '*' -N '!x' is the same as -w -N '!x' -N '*'. @<FILE> Read command-line options and commands from response file <FILE>. ELF-SPECIFIC OPTIONS The following options are implemented only for ELF objects. If used with other objects, llvm-strip will either emit an error or silently ignore them. --allow-broken-links Allow llvm-strip to remove sections even if it would leave invalid section references. Any invalid sh_link fields will be set to zero. --discard-locals, -X Remove local symbols starting with ".L" from the output. --keep-file-symbols Keep symbols of type STT_FILE, even if they would otherwise be stripped. --keep-section <section> When removing sections from the output, do not remove sections named <section>. Can be specified multiple times to keep multiple sec- tions. --keep-symbol <symbol>, -K When removing symbols from the output, do not remove symbols named <symbol>. Can be specified multiple times to keep multiple symbols. --preserve-dates, -p Preserve access and modification timestamps in the output. --strip-sections Remove from the output all section headers and all section data not within segments. Note that many tools will not be able to use an ob- ject without section headers. -T Remove Swift symbols. EXIT STATUS llvm-strip exits with a non-zero exit code if there is an error. Other- wise, it exits with code 0. BUGS To report bugs, please visit <- https://github.com/llvm/llvm-project/labels/tools:llvm-objcopy%2Fstrip>.
