[TTI][AArch64] Detect OperandInfo from scalable splats. (#122469) Pulled out of #122236, this allows Splats constants to be recognized by getOperandInfo, allowing "better" costs for instructions like divides by constants to be produced (which are expanded into mul+add+shift). Some of the costs are not very accurate yet, but the comparison of scalar vs fixed-width vs scalable for the same div can become more accurate, especially with patches like #122236.
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.

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