[mlir][Transforms][NFC] `remove-dead-values`: Erase ops at the end (#174208) `remove-dead-values` performs various cleanups: 1. Erasing block arguments 2. Erasing successor operands 3. Erasing operations 4. Erasing function arguments / results 5. Erasing operands 6. Erasing results This commit moves Step 3 (erasing operations) to the end. While that does not fix any bugs by itself, it is potentially safer. If an operation is erased, we must be careful that the operation is not accessed in the following steps. That can no longer happen if IR is erased only in the final step and not before. This commit is prefetching a change from #173505 (to keep that PR shorter). With #173505, it will become necessary to erase IR in the final step.
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.
