[AArch64][ISel] Select constructive SVE2 ext instruction This adds patterns for selecting EXT_ZZI_B. They are tested for fixed vectors using extract shuffles, and for scalable vectors using llvm.vector.splice intrinsics. We will get better codegen when enabling subreg liveness. Without it, any use of a zpr2 tuple is always considered as using both zpr registers of the pair.
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.
