[InlineSpiller] Check rematerialization before folding operand (#134015)
Current implementation tries to fold the operand before
rematerialization because it can reduce one register usage. But if there
is a physical register available we can still rematerialize it without
causing high register pressure.
This patch do this check to find the better choice. Then we can produce
xorps %xmm1, %xmm1
ucomiss %xmm1, %xmm0
instead of
ucomiss LCPI0_1(%rip), %xmm0
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.
Join the LLVM Discourse forums, Discord chat, LLVM Office Hours or Regular sync-ups.
The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
