Reapply [AMDGPU] prevent shrinking udiv/urem if either operand exceeds signed max (#119325) This reverts commit 254d206ee2a337cb38ba347c896f7c6a14c7f218. +Added a fix in ExpandDivRem24 to disqualify if DivNumBits exceed 24. Original commit & msg: ce6e955ac374f2b86cbbb73b2f32174dffd85f25. Handle signed and unsigned path differently in getDivNumBits. Using computeKnownBits, this rejects shrinking unsigned div/rem if operands exceed signed max since we know NumSignBits will be always 0.
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.
