The affine-loop-invariant-code-motion pass was hoisting side-effectful operations (e.g. affine.store) out of loops whose trip count is statically known to be zero. This caused stores to execute unconditionally even though the loop body should never run, producing incorrect results. The fix skips hoisting of non-memory-effect-free ops when getConstantTripCount returns 0. Pure/side-effect-free ops are still eligible for hoisting because they cannot change observable program state. Fixes #128273 Assisted-by: Claude Code
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.
