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 enabled.

       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. Additionally, 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 default.

       --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 combination with -o.

       --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  multiple  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.attribute sections and the section
              name table.

              For COFF objects, remove all symbols, debug  sections,  and  relocations  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 characters │ .*         │
                           ├───────────────┼──────────────────────────┼────────────┤
                           │?              │ Any single character     │ .          │
                           ├───────────────┼──────────────────────────┼────────────┤
                           │\              │ Escape     the      next │ \          │
                           │               │ character                │            │
                           ├───────────────┼──────────────────────────┼────────────┤
                           │[a-z]          │ Character class          │ [a-z]      │
                           ├───────────────┼──────────────────────────┼────────────┤
                           │[!a-z], [^a-z] │ Negated character class  │ [^a-z]     │
                           └───────────────┴──────────────────────────┴────────────┘

              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>.

COFF-SPECIFIC OPTIONS

       The  following  options are implemented only for COFF objects. If used with other objects,
       llvm-strip will either emit an error or silently ignore them.

       --only-keep-debug
              Remove the contents of non-debug sections from the output,  but  keep  the  section
              headers.

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 sections.

       --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  object  without  section
              headers.

       -T     Remove Swift symbols.

EXIT STATUS

       llvm-strip exits with a non-zero exit code if there is an error.  Otherwise, it exits with
       code 0.
