hipcc and clang++ both have logic to detect the installed hardware and to automatically select the appropriate AMDGPU target when it is left unspecified. When the AMDGPU_TARGETS property is initialized with a set of default values, it results in the addition of an explicit set of --offload-arch flags being passed. These explicit architecture flags disable the architecture autodetection in the compiler. The resulting behaviour from setting fixed defaults makes it unpleasant to compile with CMake because they increase the build times for projects unless they are overriden (as most users do not need to build for all five default architectures). The fixed defaults are also troublesome for users with hardware not included in the default set (e.g., gfx1011, gfx1031, gfx1100). A possible alternative might be to detect the architecture within hip-config.cmake rather than running the detection logic on each compiler invocation. However, this approach is simpler.

AMD CLR - Compute Language Runtimes
AMD Common Language Runtime contains source code for AMD's compute languages runtimes: HIP and OpenCL™.
Project Organisation
hipamd- contains implementation ofHIPlanguage on AMD platform. Previously this was hosted at ROCm-Developer-Tools/hipamdopencl- contains implementation of OpenCL™ on AMD platform. Previously this was hosted at RadeonOpenCompute/ROCm-OpenCL-Runtimerocclr- contains common runtime used inHIPandOpenCL™. Previously this was hosted at ROCm-Developer-Tools/ROCclr
How to build/install
Prerequisites
Please refer to Prerequisite Actions in ROCm Installation Guide in release documentation.
Linux
- Clone this repo
cd clr && mkdir build && cd build- For HIP :
cmake .. -DCLR_BUILD_HIP=ON -DHIP_COMMON_DIR=$HIP_COMMON_DIRHIP_COMMON_DIRpoints to HIP
- For OpenCL™ :
cmake .. -DCLR_BUILD_OCL=ON make: to buildmake install: to install
Users can also build OCL and HIP at the same time by passing -DCLR_BUILD_HIP=ON -DCLR_BUILD_OCL=ON to configure command.
