💖 NAME 💖

llvm-rtdyld — okay bestie, this is the manual page for llvm-rtdyld 22, and it is the llvm MC-JIT tool. that's the whole vibe. it takes your object files, links them up in memory, and actually runs them. no cap. 🦋

✨ DESCRIPTION ✨

OVERVIEW: llvm MC-JIT tool 🌈

USAGE:

llvm-rtdyld [options] <input files> --args <program arguments>...

so like, you feed it <input files>, sprinkle your <program arguments> in after --args, and it goes to work. underneath all of that is a big pile of OPTIONS, and we are gonna go through every single one, because that's what we do here. 💅

🎀 Color Options 🎀

  • --color — use colors in output. default is autodetect, so it decides for itself whether your terminal is cute enough. 👑

🫶 Generic Options 🫶

  • --help — display the available options. want the spicy hidden ones? that's --help-hidden for more. 😌
  • --help-list — display a list of the available options. again, --help-list-hidden gives you more if you're nosy (and you should be). 💖
  • --version — display the version of this program. slay.

🔥 RTDyld Options 🔥

  • --args <string>... — your <program arguments>... fr fr.
  • --check=<string> — a file containing RuntimeDyld verifier checks. it's giving "the receipts". 🧾
  • --dylib=<string> — add a library. yes, just add it, bestie. 📚
  • --entry=<string> — the function to call as the entry point. that's the main character. 👑
  • --mcpu=<cpu-name> — target a specific cpu type. and if you don't know your cpu types, -mcpu=help has the details for you. 🖥️
  • --preallocate=<ulong> — allocate memory upfront instead of on-demand. impatient icon behavior, and honestly? valid. ⚡
  • --show-times — show times for llvm-rtdyld phases. the stopwatch is ON. ⏱️
  • --triple=<string> — target triple for the disassembler. 🎯

🎬 Action to perform 🎬

pick your adventure, bestie — you gotta tell it what to do:

  • --execute — load, link, and execute the inputs. the full send. 🚀
  • --printline — load, link, and print line information for each function. 📝
  • --printdebugline — load, link, and print line information for each function, using the debug object. 🐛✨
  • --printobjline — like -printlineinfo but does not load the object first. subtle but so important. 💅
  • --verify — load, link and verify the resulting memory image. vibe check, but for bytes. 🔍
no cap: --printobjline skips loading the object first — that's genuinely different from the -printlineinfo behavior, so don't come for me when it behaves differently. 💀

okay that's the whole page, you ate it, periodt. 🫶💖✨

this lil sign-off is for llvm-rtdyld 22, dated September 2026, served piping hot from the LLVM source. bye bestie, go link something iconic. 🌸💜🌈
