Peter Waller 2d574a1104 [CodeGen][AArch64][SVE] Canonicalize intrinsic rdffr{ => _z} Follow up to D101357 / `3fa6510f6`. Supersedes D102330. Goal: Use flags setting rdffrs instead of rdffr + ptest. Problem: RDFFR_P doesn't have have a flags setting equivalent. Solution: in instcombine, canonicalize to RDFFR_PP at the IR level, and rely on RDFFR_PP+PTEST => RDFFRS_PP optimization in AArch64InstrInfo::optimizePTestInstr. While here: * Test that rdffr.z+ptest generates a rdffrs. * Use update_{test,llc}_checks.py on the tests. * Use sve attribute on functions.

The LLVM Compiler Infrastructure
================================

This directory and its subdirectories contain source code for LLVM,
a toolkit for the construction of highly optimized compilers,
optimizers, and runtime environments.

LLVM is open source software. You may freely distribute it under the terms of
the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.

If you are writing a package for LLVM, see docs/Packaging.rst for our
suggestions.
