Reapply "[mlir][linalg] Make conv dim inference return pairing (outputImage, filterLoop)" (#182740) The original method sorts all the dimensions which loses the information about pairing. It makes other transformation that works on generic op form harder. The revision ensures the pairing, so callers have more useful information when they work on transformations. The revision was reverted because of memory leak. The fix is using OwningOpRef to wrap ModuleOp, so the nested operations are destroyed at the end, which is similar to other MLIR unittests. --------- Signed-off-by: hanhanW <hanhan0912@gmail.com>
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.
