Changelog for hipObject

(Unreleased) hipObject 0.1.0

Added

Changed

• hipObject is now built as plain C/C++ instead of HIP. It contains no GPU kernels, so the HIP language (and its per-architecture device compilation pass) is no longer enabled. The HIP runtime is still used via the hip::host CMake target. CMAKE_HIP_COMPILER no longer needs to be set when configuring.
• hipObject is now built as C++20 (without compiler extensions) instead of C++17, so a C++20-capable compiler is required. The HIPOBJ_CXX_STANDARD CMake cache variable now defaults to 20.
• hipObject is now built as a shared library (libhipobj.so) by default. The BUILD_SHARED_LIBS CMake option, which was previously ignored, now selects between a shared and a static library and defaults to ON. Set it to OFF to build the static library (libhipobj.a) as before. The shared library exports only the public C API declared in hipobj.h.
• The hipobj::hipobj CMake target no longer passes hip::host and hsa-runtime64::hsa-runtime64 on to consumers, since hipobj.h doesn't include HIP or HSA headers. Consumers that use HIP themselves must link hip::host directly.

Removed

• The OFFLOAD_ARCH CMake cache variable and its rocminfo-based GPU architecture detection. It was never used to set the target architecture and is unnecessary now that nothing is compiled for the GPU.
• The hipObjInitV2() declaration in hipobj.h. The function was never implemented, so calls to it failed at link time. They now fail to compile.
