Update handling of math errno. This change updates the logic for generation of math intrinics in place of math library function calls. The previous logic https://reviews.llvm.org/D151834 was incorrectly using intrinsics when math errno handling was needed at optimization levels above -O0. This also fixes issue mentioned in https://reviews.llvm.org/D151834 by @uabelho This is joint work with @andykaylor Andy.
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
