[BOLT][AArch64] Speed up ICF pass (#172783) Add hashing support for MCSpecifierExpr, which is frequently used as an operand in AArch64 instructions. Proper hashing reduces collisions when placing functions into buckets, resulting in shorter Identical Code Folding (ICF) pass runtime. In one benchmark, the ICF wall time decreased from 272s to 124s.
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.
Consult the Getting Started with LLVM page for information on building and running LLVM.
For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.
