Release Notes

The release notes for the ROCm platform.

ROCm 5.4.2

Deprecations and Warnings

HIP Perl Scripts Deprecation

The hipcc and hipconfig Perl scripts are deprecated. In a future release, compiled binaries will be available as hipcc.bin and hipconfig.bin as replacements for the Perl scripts.

Note

There will be a transition period where the Perl scripts and compiled binaries are available before the scripts are removed. There will be no functional difference between the Perl scripts and their compiled binary counterpart. No user action is required. Once these are available, users can optionally switch to hipcc.bin and hipconfig.bin. The hipcc/hipconfig soft link will be assimilated to point from hipcc/hipconfig to the respective compiled binaries as the default option.

`hipcc` Options Deprecation

The following hipcc options are being deprecated and will be removed in a future release:

The --amdgpu-target option is being deprecated, and user must use the –offload-arch option to specify the GPU architecture.
The --amdhsa-code-object-version option is being deprecated. Users can use the Clang/LLVM option -mllvm -mcode-object-version to debug issues related to code object versions.
The --hipcc-func-supp/--hipcc-no-func-supp options are being deprecated, as the function calls are already supported in production on AMD GPUs.

Known Issues

Under certain circumstances typified by high register pressure, users may encounter a compiler abort with one of the following error messages:

error: unhandled SGPR spill to memory
cannot scavenge register without an emergency spill slot!
error: ran out of registers during register allocation

This is a known issue and will be fixed in a future release.
