asm-parser

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

Example usage

Feeding an objdump via stdin into asm-parser:

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