## Change: * Added `--dump-dot-func` command-line option that allows users to dump CFGs only for specific functions instead of dumping all functions (the current only available option being `--dump-dot-all`) ## Usage: * Users can now specify function names or regex patterns (e.g., `--dump-dot-func=main,helper` or `--dump-dot-func="init.*`") to generate .dot files only for functions of interest * Aims to save time when analysing specific functions in large binaries (e.g., only dumping graphs for performance-critical functions identified through profiling) and we can now avoid reduce output clutter from generating thousands of unnecessary .dot files when analysing large binaries ## Testing The introduced test `dump-dot-func.test` confirms the new option does the following: - [x] 1. `dump-dot-func` can correctly filter a specified functions - [x] 2. Can achieve the above with regexes - [x] 3. Can do 1. with a list of functions - [x] No option specified creates no dot files - [x] Passing in a non-existent function generates no dumping messages - [x] `dump-dot-all` continues to work as expected
