[AArch64] Use pattern to select bf16 fpextend (#137212) Currently bf16 fpextend is lowered to a vector shift. Instead leave it as fpextend and have an instruction selection pattern which selects to a shift later. Doing this means that DAGCombiner patterns for fpextend will be applied, leading to better codegen. It also means that in some situations we use a mov instruction where we previously have a dup instruction, but I don't think this makes any difference.
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.

The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
