[mlir][MemRef] Migrate memref dialect alias op folding to interface (#187168) This PR adds code to FoldMemRefAliasOps / --fold-memref-alias-ops to use the new IndexedMemoryAccessOpInterface and IndexedMemCopyOpInterface and implement those operations for relevant operations in the memref dialect. This is a reordering of the changes planned in #177014 and #177016 to make them more testable. There are no behavior changes expected for how memref.load and memref.store behave within the alias ops folding pass, though support for new operations, like memref.prefetch, has been added. Some error messages have been updated because certain laws of memref.load/memref.store have been moved to IndexedAccessOpInterface. Assisted-by: Claude 4.6 (helped deal with some of the boilerplate in the rewrite patterns and with extracting the patch)
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.

The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
