[mlir][SparseTensor] add `numSymbols` information to simplify affine expressions (#191649) Previously, the `translateShape` function hard-coded the `numSymbols` parameter to 0. This makes the affine expression fail when the sparse tensor encoding has symbols. This PR fixes the issue by extracting and passing the `numSymbols` information during translation. A regression test has also been added to ensure this behavior remains supported. Closes #191209
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.
