[AMX][PreTileConfig] Ensure that PLDTILECFGV instruction is sinked closer to tile use instruction. (#155673) According AMX ABI, tile registers (including config) are volatile hence requiring caller to save/restore config register. This is done in X86's FastPreTileConfig pass. Currently the PLDTILECFGV instruction is emitted immediately after the call which can be problematic if call returns a value in say rax register and AMX tile is configured using the same register. This PR addresses this issue by ensuring that PLDTILECFGV is sinked closer to first instruction using a tile after the call.
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.
