[MLIR][Affine] Fix/complete access index invariance, add isInvariantAccess (#84602) isAccessIndexInvariant had outdated code and didn't handle IR with multiple affine.apply ops, which is inconvenient when used as a utility. This is addressed by switching to use the proper API on AffineValueMap. Add mlir::affine::isInvariantAccess exposed for outside use and tested via the test pass. Add a method on AffineValueMap. Add test cases to exercise simplification and composition for invariant access analysis. A TODO/FIXME has been added but this issue existed before.
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.
