---

✨ SYNOPSIS ✨

cg_diff [options] cachegrind-out-file1 cachegrind-out-file2

💅 DESCRIPTION 💅

cg_diff diffs two Cachegrind output files into a single Cachegrind output file. It is deprecated because cg_annotate can now do much the same thing, but better. no cap, that's literally the situation 😭

🎀 OPTIONS 🎀

• -h, --help — shows the help message.
• --version — shows the version number.
• --mod-filename=<expr> — [default: none] specifies an s/old/new/ search-and-replace expression that is applied to all filenames ✨
• --mod-funcname=<expr> — [default: none] like --mod-filename, but for filenames. yes bestie, that is what it says 🫶
