Dear Maintainer,
On ppc64el, the clang compiler crashed on buildd [1] during the
compilation of test_block_sort.cpp in the rocprim package. We're only
compiling HIP programs for ppc64el on a best-effort basis, as it is not
an officially supported architecture upstream. Nevertheless, a compiler
crash seemed to be worth reporting. I've reproduced this problem on my
local machine in a QEMU VM.
There were also linking errors related to half-floats in the build log
(__truncdfhf2), but that is unrelated. I fixed that bug in rocm-hipamd
locally before reproducing the crash.
The full log is linked below, but I'll include a snippet inline:

Does it happen with clang-16 ?
could you please try to provide a testcase with creduce ?
thanks
