[Clang][LLVM][AArch64]Add support for svrint{32|64}{z|x} intrinsics (#169661)

This patch add supports in Clang for these assembly intrinsics:

FRINT32X
FRINT32Z
FRINT64X
FRINT64Z

By adding support for these intrinsics:

// Variant is available for _f64
svfloat32_t svrint32x[_f32]_z(svbool_t pg, svfloat32_t zn); // Variant
is available for _f64
svfloat32_t svrint32x[_f32]_x(svbool_t pg, svfloat32_t zn); // Variant
is available for _f64
svfloat32_t svrint32x[_f32]_m(svfloat32_t inactive, svbool_t pg,
svfloat32_t zn);

// Variant is available for _f64
svfloat32_t svrint32z[_f32]_z(svbool_t pg, svfloat32_t zn); // Variant
is available for _f64
svfloat32_t svrint32z[_f32]_x(svbool_t pg, svfloat32_t zn); // Variant
is available for _f64
svfloat32_t svrint32z[_f32]_m(svfloat32_t inactive, svbool_t pg,
svfloat32_t zn);

// Variant is available for _f64
svfloat32_t svrint64x[_f32]_z(svbool_t pg, svfloat32_t zn); // Variant
is available for _f64
svfloat32_t svrint64x[_f32]_x(svbool_t pg, svfloat32_t zn); // Variant
is available for _f64
svfloat32_t svrint64x[_f32]_m(svfloat32_t inactive, svbool_t pg,
svfloat32_t zn);

// Variant is available for _f64
svfloat32_t svrint64z[_f32]_z(svbool_t pg, svfloat32_t zn); // Variant
is available for _f64
svfloat32_t svrint64z[_f32]_x(svbool_t pg, svfloat32_t zn); // Variant
is available for _f64
svfloat32_t svrint64z[_f32]_m(svfloat32_t inactive, svbool_t pg,
svfloat32_t zn);

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices libc++

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.

Getting the Source Code and Building LLVM

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.

Getting in touch

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.
