[LV] Fix branch weights in epilogue min iteration check block (#152534) I've changed how we construct the EpilogueVectorizerEpilogueLoop and EpilogueVectorizerMainLoop classes so that we construct the parent class with an additional boolean parameter indicating whether we're vectorising the main or epilogue loop. The InnerLoopAndEpilogueVectorizer class uses this new argument in combination with the EpilogueLoopVectorizationInfo struct to set the right UF and VF values. This then allows EpilogueVectorizerEpilogueLoop to access the correct values of VF and UF for the main loop, which are required when setting branch weights in the minimum iteration check block.
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.
