[Clang] Permit '--target=amdgcn--' for binaries (#191451) Summary: We always accepted `--target=amdgcn--` to create IR object files but it doesn't allow creating actual binaries without user intervention. This is because it would fall-through to the GCC toolchain which does not know how to handle AMGCN / AMDGPU targets. This PR just adds a single line to handle it, which effectively allows this as a 'bare' target. Perhaps the argument could be made that AMDGPU should not support anything but strictly HSA because it has many assumptions in the compiler itself, such as implicit arguments, but I feel like it is relatively harmless to support this case if users decide they really do not need it.
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.
Consult the Getting Started with LLVM page for information on building and running LLVM.
