[mlir][arith] Fix crash in IntRangeOptimizations due to stale solver state (#186187) When the IntRangeOptimizationsPass runs applyPatternsGreedily with constant folding enabled, constant folding can restructure blocks — for example by removing a block argument. The integer range solver, which pre-computed range information for the original block arguments, is now out of sync: subsequent range queries about the new (reused) argument positions return stale information computed for the old arguments, causing crashes. Fix by passing enableConstantFolding(false) in GreedyRewriteConfig so that the solver's state remains consistent with the IR throughout the rewrite. Fixes #122076 Assisted-by: Claude Code
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.
