For pwr9, xxspltib is a byte splat with a range -128 to 127 - it can be used with a following vector extend sign to make splats of i16, i32, or i64 element size. For pwr8, vspltisw with a following vector extend sign can be used to make splats of i64 elements in the range -16 to 15. Add check for P8 to make sure the 64-bit vector ops are there.
The LLVM Compiler Infrastructure
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.
