✨ LLVM-AS ✨

okay bestie, welcome to the llvm-as page — that's the LLVM assembler, living in section 1 of the LLVM manual 💅

🌸 NAME 🌸

llvm-as — the LLVM assembler, and yes she's that girl 🎀

🦋 SYNOPSIS 🦋

llvm-as [options] [filename]

💖 DESCRIPTION 💖

okay so llvm-as is the LLVM assembler. no cap. she reads a file that's full of human-readable LLVM assembly language, translates it into LLVM bitcode, and then writes the result either into a file or straight to standard output. it's giving translator, it's giving glow-up, she ate 💅

if filename is omitted, or if it's literally -, then llvm-as takes her input from standard input. she's flexible like that 🫶

and if you don't specify an output file with the -o option? she follows these rules to figure out where her output goes, lowkey iconic behaviour:

  • If the input is standard input, then the output is standard output. 💫
  • If the input is a file that ends with .ll, then the output file is of the same name, except that the suffix is changed to .bc. ✨
  • If the input is a file that does not end with the .ll suffix, then the output file has the same name as the input file, except that the .bc suffix is appended. 🌈

👑 OPTIONS 👑

  • -f — Enable binary output on terminals. normally, llvm-as will refuse to write raw bitcode output if the output stream is a terminal (she has boundaries 💀). with this option, llvm-as will write raw bitcode regardless of the output device. no vibe check, just send it.
  • -help — Print a summary of command line options. she'll tell you everything she can do, main character energy fr fr 👑
  • -o filename — Specify the output file name. and if filename is -, then llvm-as sends its output to standard output. classic move 🌸

💀 EXIT STATUS 💀

if llvm-as succeeds, she exits with 0. slay. otherwise, if an error occurs, she exits with a non-zero value. sad girl hours 😭
