LLVM-SIZE(1)

💖 LLVM-SIZE(1): llvm-size is here to measure ur objects 💖

🌸 NAME 🌸

llvm-size — manual page for llvm-size 18 💅 this is literally the one, bestie.

🦋 DESCRIPTION 🦋

OVERVIEW: LLVM object size dumper. It’s giving “I inspect object files and dump their sizes” energy, and honestly? iconic.

USAGE:

build-llvm/tools/clang/stage2-bins/bin/llvm-size [options] <input object files>

Run it with [options] plus those <input object files> and you’re good 🫶.

💅 OPTIONS: 💅

• -A — alias for --format ✨
• -B — alias for --format ✨
• --common — prints common symbols in the ELF file. When using Berkeley format, this is added to bss 👑
• -d — alias for --radix=10
• --format=<value> — specify output format 🎀
• --help — displays this help, bestie
• -h — alias for --help
• -m — alias for --format
• -o — alias for --radix=8
• --radix=<value> — prints the size in radix 🔢
• --totals — prints totals of all objects — Berkeley format only 💀
• -t — alias for --totals
• --version — displays the version 🌈
• -x — alias for --radix=16

🦋 OPTIONS (Mach-O specific): 🦋

• --arch=<value> — architecture(s) from a Mach-O file to dump 🧚
• -l — when the format is darwin, use long format to include addresses and offsets ✨

Pass @FILE as argument to read options from FILE 📝 — yes, that’s the exact move.
