This is fairly straightforward for most targets. We use the element-wise sqrt builtin by default. We also remove a legacy pre-filtering of the input argument, which the intrinsic now officially handles. AMDGPU provides its own implementation of sqrt for double types. This commit moves this into the implementation of CLC sqrt. It uses weak linkage on the 'default' CLC sqrt to allow AMDGPU to only override the builtin for the types it cares about.
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.
