## 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
The LLVM Compiler Infrastructure
Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called "LLVM". This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
