asm-parser

This repo is extracted from compiler-explorer

I only included the cpp demangler, PR is welcomed.

Categorises and filters assembly in a way that's understood by Compiler Explorer.

Possible filters as command line parameters:

• --binary changes to the Binary mode filtering that's based on the assembly output from GNU Objdump
• --unused_labels try to filter out functions that aren't strongly used
• --directives filter out .directives
• --library_code try to filter out functions that belong in other libraries that are used (filtering is based on filepaths)
• --comment_only filter out comments
• --outputtext Instead of writing to JSON, output the filtered assemblys

Example usage

The filename has to be example.*

Feeding an objdump via stdin into asm-parser:

gcc -g -S -masm=intel -o - example.cpp | npm run --silent parse -- --unused_labels --library_code --directives --comment_only > example.asm

gcc -g -S -masm=intel -o - example.cpp | ./asm-parser-win.exe --unused_labels --library_code --directives --comment_only > example.asm
gcc -g -S -masm=intel -o - example.cpp | ./asm-parser-linux --unused_labels --library_code --directives --comment_only > example.asm
gcc -g -S -masm=intel -o - example.cpp | ./asm-parser-macos --unused_labels --library_code --directives --comment_only > example.asm
