ROCm LLVM compiler infrastructure

The AMD llvm-project is a fork of llvm/llvm-project. The AMD code is open and hosted at ROCm/llvm-project.

Conceptual

• Using AddressSanitizer

• OpenMP support

• Code portability and compression

• ROCm support for SPIR-V (beta)

Reference

• AMD ROCm compiler reference

• Clang documentation

• Clang-tools documentation

• HIPCC documentation

• HIPIFY documentation

• LLD documentation

• LLVM documentation

ROCm includes multiple compilers of varying origins and purposes as described in the following table:

Name	Description
amdclang++	Clang/LLVM-based compiler that is part of rocm-llvm package. The source code is available at ROCm/llvm-project.
AOCC	Closed-source clang-based compiler that includes additional CPU optimizations. NOTE: AOCC is not delivered as part of ROCm. For more information, see https://developer.amd.com/amd-aocc.
HIP-Clang	Another name for the amdclang++ compiler.
HIPIFY	Tools used to automatically translate CUDA source code into portable HIP C++, including hipify-clang and hipify-perl. The source code is available at ROCm/HIPIFY.
hipcc	HIP compiler driver utility that invokes clang or nvcc and passes the appropriate include and library options for the target compiler and HIP infrastructure. See the ROCm/llvm-project for more information.

AMD ROCm also provides additional open-source utilities and libraries for building GPU code located in the llvm-project/amd directory:

Name	Description
amd/comgr	The Code Object Manager API, designed to simplify linking, compiling, and inspecting code objects. See the llvm-project/amd/comgr/README for more information.
amd/device-libs	The sources and CMake build system for a set of AMD-specific device-side language runtime libraries. See the llvm-project/amd/device-libs/README for more information.
