Currently we have slightly different costing for the vp and non-vp version of the rounding intrinsics. We can delete this code and use the generic BasicTTIImpl code for the vp intrinsics which falls back to the non-vp versions. I'm not sure if the zvfh costing is correct, this should probably be fixed in a follow up patch. At the moment the non-vp cost is more important since it is what the loop vectorizer will use.
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.
