💅 emstrip(1) — bestie's guide to llvm-strip energy

okay so, hi. welcome to emstrip, the emscripten wrapper around llvm-strip. this manual is from the User Commands girlies, and she's serving stripping binaries, no cap. 🎀✨

✨ NAME ✨

emstrip — the emscripten wrapper around llvm-strip 🦋

🌸 DESCRIPTION 🌸

Here's the whole vibe, straight up:

OVERVIEW: llvm-strip tool

USAGE: llvm-strip [options] inputs...

like… that's it. that's the whole tool. now let's get into the options because there are so many and honestly she ate. 🔥

👑 OPTIONS 👑

  • --allow-broken-links — lets the tool go ahead and remove sections even when doing that would leave invalid section references behind (messy of her, but okay). when that happens, the appropriate sh_link fields get set to zero. problem solved, sorta. 💅
  • --disable-deterministic-archives — turns deterministic mode OFF when you're operating on archives, so it uses real values for UIDs, GIDs, and timestamps. 🕰️
  • --discard-all — removes most local symbols. different file formats may limit this to a subset though — for ELF, file and section symbols are not discarded. AND on top of that, it removes all debug sections too. double homicide. 💀
  • --discard-locals — removes local symbols starting with .L
  • -D — alias for --enable-deterministic-archives
  • -d — alias for --strip-debug
  • --enable-deterministic-archives — turns deterministic mode ON when operating on archives, using zero for UIDs, GIDs, and timestamps. ✨
  • -g — alias for --strip-debug
  • --keep-file-symbols — keeps symbols of type STT_FILE, even if they would otherwise be stripped. protective queen. 🫶
  • --keep-section=section — keep <section>
  • --keep-symbol=symbol — when removing symbols, do not remove <symbol>
  • -K <value> — alias for --keep-symbol
  • --no-strip-all — disables --strip-all
  • -N <value> — alias for --strip-symbol
  • --only-keep-debug — produces a debug file as the output that only preserves contents of sections useful for debugging purposes
  • -o <file> — write output to <file>
  • --preserve-dates — preserves access and modification timestamps
  • -p — alias for --preserve-dates
  • --regex — permits regular expressions in name comparison
  • --remove-section=section — remove <section>
  • -R <value> — alias for --remove-section
  • --strip-all-gnu — removes all symbols, debug sections and relocations. compatible with GNU's --strip-all 😌
  • --strip-all — for ELF, removes all symbols and non-alloc sections not within segments, EXCEPT for .gnu.warning*, .ARM.attribute, and the section name table. for COFF and Mach-O, removes all symbols, debug sections, and relocations
  • --strip-debug — removes all debug sections
  • --strip-sections — removes all section headers and all section data not within segments
  • --strip-symbol=symbol — strip <symbol>
  • --strip-unneeded — removes all symbols not needed by relocations
  • -S — alias for --strip-debug
  • -s — alias for --strip-all
  • -T — removes Swift symbols
  • -U — alias for --disable-deterministic-archives
  • --version — prints the version and exits.
  • -V — alias for --version
  • --wildcard — allows wildcard syntax for symbol-related flags. incompatible with --regex, fyi. lets you use * to match any number of characters, ? to match any single character, '' to escape special characters, and [] to define character classes. wildcards beginning with ! will prevent a match — for example "-N '*' -N '!x'" will strip all symbols except for "x". iconic behaviour tbh. 🧚
  • -w — alias for --wildcard
  • -X — alias for --discard-locals
  • -x — alias for --discard-all

🍎 OPTIONS (Mach-O specific) 🍎

just the apple girlies, don't worry about it:

  • --keep-undefined — do not remove undefined symbols
psst — pass @FILE as argument to read options from FILE. sneaky and efficient, love that for you. 📄💜

and that's the whole page, bestie!! rip it, strip it, slay it. 💅🌈
