[RISCV] Update MicroOpBufferSize in P400 & P600 scheduling models (#128786) The numbers we previously picked for MicroOpBufferSize in both P400 and P600's scheduling models turned out to be too conservative and didn't properly reflect the characteristics of our microarchitectures. This patch updates these numbers to be more faithful to our hardware. This is unlikely to have any significant impact on MachineScheduler as it only uses MicroOpBufferSize in few places. That said, it is supposed to improve the accuracy of llvm-mca.
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.
