compress is intented to match vcompress from the ISA manual. Note that deinterleave is a subset of this, and is already tested elsewhere. decompress is the synthetic pattern defined in same - though we can often do better than the mentioned iota/vrgather. Note that some of these can also be expressed as interleave with at least one undef source, and is already tested elsewhere. repeat repeats each input element N times in the output. It can be described as as a interleave operations, but we can sometimes do better lowering wise.
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.
Getting the Source Code and Building LLVM
Consult the Getting Started with LLVM page for information on building and running LLVM.
