# ROCm compilers disambiguation ROCm ships multiple compilers of varying origins and purposes. This article disambiguates compiler naming used throughout the documentation. ## Compiler terms | Term | Description | | - | - | | `amdclang++` | Clang/LLVM-based compiler that is part of `rocm-llvm` package. The source code is available at https://github.com/ROCm/llvm-project. | | AOCC | Closed-source clang-based compiler that includes additional CPU optimizations. Offered as part of ROCm via the `rocm-llvm-alt` package. See for details, https://developer.amd.com/amd-aocc/. | | HIP-Clang | Informal term for the `amdclang++` compiler | | HIPIFY | Tools including `hipify-clang` and `hipify-perl`, used to automatically translate CUDA source code into portable HIP C++. The source code is available at https://github.com/ROCm/HIPIFY | | `hipcc` | HIP compiler driver. A utility that invokes `clang` or `nvcc` depending on the target and passes the appropriate include and library options for the target compiler and HIP infrastructure. The source code is available at https://github.com/ROCm/HIPCC. | | ROCmCC | Clang/LLVM-based compiler. ROCmCC in itself is not a binary but refers to the overall compiler. |
