LLVM-DIS(1)

💅 LLVM-DIS(1) — the llvm-dis manual, bestie edition ✨

okay so you opened the manual for llvm-dis, part of the LLVM fam, and honestly? it's a short one, we love a low-effort icon. let's get into it 🫶

---

🌸 NAME 🌸

llvm-dis — the LLVM disassembler. that's it, that's the name. short, sweet, main character energy 👑

---

✨ SYNOPSIS ✨

llvm-dis [options] [filename]

literally just that. options, then a filename, no drama 🎀

---

🦋 DESCRIPTION 🦋

so llvm-dis is the LLVM disassembler, and what it does is take an LLVM bitcode file and turn it into human-readable LLVM assembly language. glow-up translation, basically. machine soup in, readable text out 💖

if you skip filename entirely, or pass it as -, then llvm-dis reads its input from standard input. no filename needed, she'll take it straight from the pipe 🧚

and here's the output tea ☕ — if the input is coming from standard input, the output goes to standard output by default. but if the input is a real 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. so thing.bc becomes thing.ll, iconic behaviour. you can override the whole output-file situation with the -o option if you're feeling picky 💅

---

🔥 OPTIONS 🔥

• -f — enables binary output on terminals. normally llvm-dis will refuse to write raw bitcode output if the output stream is a terminal, like a bouncer at the club 🚫. with this option, llvm-dis will write raw bitcode regardless of the output device. no cap, it just does it.
• -help — prints a summary of command line options. your little cheat sheet, bestie 📝
• -o filename — specify the output file name. and if filename is -, then the output is sent to standard output. dash means stdout, always and forever 🫶

⚠️ heads up: that -f thing exists because dumping raw bitcode at a terminal is normally a whole mess. only reach for it when you actually mean it, okay? 💀

---

🌈 EXIT STATUS 🌈

if llvm-dis succeeds, it exits with 0. slay. otherwise, if an error occurs, it exits with a non-zero value. so like, check your exit codes, that's the vibe check 😭
