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
• -comment_only filter out comments
• -whitespace
• -library_functions try to filter out functions that belong in other libraries that are used (filtering is based on filepaths)
• -dont_mask_filenames always output the filename if available

Other parameters:

• -plt Also leaves out labels that End with @plt (without this, only labels that Start with .plt are left out)
• -nocompat Leaves some experimental extra information
• -stdin Reads assembly from STDIN instead of from a given file
• -outputtext Instead of writing to JSON, output the filtered assemblys

Feeding an objdump via stdin into asm-parser:

objdump -d a.out -l --insn-width=16 | asm-parser -stdin -binary

You'll need gcc 12 or later (or hack your settings to support your compiler).

1. setup.sh sets up a venv, installs conan2 in it and uses that to install packages (fmt needs to be explicitly built for some reason):

$ ./setup.sh

1. Then you can:

$ cd build
$ cmake .. -DCMAKE_BUILD_TYPE=Debug
$ make -j$(nproc)
$ make test

(see https://github.com/compiler-explorer/asm-parser/blob/main/build.sh for an example, you might need to configure PATH first before doing so)

The built executable should be found in the path ./build/src/asm-parser .
