[AMDGPU][Scheduler] Simplify scheduling revert logic (#177203) When scheduling must be reverted for a region, the current implementation re-orders non-debug instructions and debug instructions separately; the former in a first pass and the latter in a second pass handled by a generic machine scheduler helper whose state is tied to the current region being scheduled, in turns limiting the revert logic to only work on the active scheduling region. This makes the revert logic work in a single pass for all MIs, and removes the restriction that it works exclusively on the active scheduling region. The latter enables future use cases such as reverting scheduling of multiple regions at once.
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.
