[MLIR] Improve compose expand(collapse) pattern (#117768) If expand(collapse) has a dimension that gets collapsed and then expanded to the same shape, the pattern would fail to canonicalize this to a single collapse shape. Line 341 was changed because the expand(collapse) could be a reinterpret-cast like sequence where the shapes differ but the rank is the same. This cannot be represented by a single `collapse_shape` op. Signed-off-by: Ian Wood <ianwood2024@u.northwestern.edu>
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.
