Need to add NumSrcElts param to is..Mask functions in ShuffleVectorInstruction class for better mask analysis. Mask.size() not always matches the sizes of the permuted vector(s). Allows to better estimate the cost in SLP and fix uses of the functions in other cases. Differential Revision: https://reviews.llvm.org/D158449
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.
