LLVM-LIB(1)

πŸ’… LLVM-LIB (that's the LLVM manual, bestie, hi 🫢)

okay so picture this: you're on Windows-adjacent vibes, you need a library tool, and llvm-lib is literally right there being iconic. yes it's the LLVM one, and yes we're gonna go through it together. grab a snack πŸ“


✨ SYNOPSIS ✨

the whole shape of it, no cap:

llvm-lib [/libpath:<path>] [/out:<output>] [/llvmlibthin] [/ignore]
         [/machine] [/nologo] [files...]

see how it's laid out? the slash-flags come first (with their <path> and <output> placeholders being all cute in angle brackets), and then [files...] at the end β€” that's your actual files, slurp 'em in last πŸ’–


🌸 DESCRIPTION 🌸

so llvm-lib is intended to be a lib.exe compatible tool. like, that's its whole thing. if you want the general deets on what that even means in the Microsoft ecosystem, the page points you at:

go read that for the big-picture description, because this page is about the extras ✨


πŸ¦‹ the llvm-lib extensions (the fun part, lowkey the main character energy)

llvm-lib has the following extensions:

  • Bitcode files in symbol tables. llvm-lib pulls symbols from both bitcode files and regular object files into the symbol table. both. at once. equal treatment. slay πŸ”₯
  • Creating thin archives. the /llvmlibthin option makes llvm-lib create a thin archive that contains only the symbol table and the header for the various members. these files are much smaller, which is gorgeous, BUT β€” and this is the important bit, don't skip it β€” they are not compatible with link.exe. lld can handle them. that's the tradeoff, iykyk πŸ’€
ok so real talk on that second one: smaller files, sure, but if you're rolling with link.exe you're gonna have a bad time. lld only. periodt.
