Fixes (keep it open) #130110. If the incoming value is PHI itself, we can skip this. If we can guarantee that the other incoming values are neither undef nor poison, then we can also guarantee that the value isn't either. If we cannot guarantee that, it makes no sense in calculating it. (cherry picked from commit 462eb7e28ef4507b16a4b45efb356bc6a3523615)
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.
