💅 NAME

llvm-dis — the LLVM disassembler, aka the girl who translates your cryptic bitcode back into something your eyeballs can actually read. We're in the LLVM manual, bestie, buckle up 🎀

✨ SYNOPSIS ✨

llvm-dis [options] [filename]

🦋 DESCRIPTION 🦋

Okay so picture this: the llvm-dis command is the LLVM disassembler. That's her whole job. She takes an LLVM bitcode file and converts it into human-readable LLVM assembly language. Glow-up of the century, literally 💅✨

If filename is left out entirely, or if you pass it as -, then llvm-dis reads its input from standard input. No file, no problem, she's flexible like that 🫶

Now here's the tea on where the output goes ☕ — if the input is coming from standard input, then llvm-dis sends its output to standard output by default. Iconic, symmetric, we love a matching set. Otherwise (i.e. you gave her an actual file), the output gets written to a file named after the input file, with a .ll suffix added — and any existing .bc suffix gets removed first, because we don't do redundant extensions in this house 🙈

And if you wanna be the main character and pick your own destination? You can override the choice of output file using the -o option. Go off, honestly 👑

🔥 OPTIONS 🔥

  • -f — Enable binary output on terminals. Bestie listen, normally llvm-dis will refuse to write raw bitcode output if the output stream is a terminal — she's got boundaries. But with this option, llvm-dis will write raw bitcode regardless of the output device. No vibe check, no hesitation, just raw bytes straight to your terminal 💀
  • -help — Print a summary of command line options. Your little cheat sheet, your bestie handing you the notes before class 📝✨
  • -o filename — Specify the output file name. And if filename is -, then the output is sent to standard output. Back to stdout we go, full circle moment 🌈

💖 EXIT STATUS 💖

If llvm-dis succeeds, she exits with 0 — a clean slay, no notes, we're thriving 🎀

Otherwise, if an error occurs, she'll exit with a non-zero value. Not every day can be a good day, and that's okay 😭
