Dear FTP Masters,
Please remove from unstable the ppc64el binaries for rocfft and all
its reverse dependencies. I believe hipfft is the only other package
to be removed. The spfft package was a reverse dependency of rocfft
on ppc64el in spfft 1.1.1-4 and earlier, but the ROCm backend for
ppc64el was removed in spfft 1.1.1-5.
rocfft 6.4.3-1 FTBFS on ppc64el due to an internal compiler error [1].
This is blocking migration of the new rocfft package to testing.
The cost-benefit ratio for fixing the compiler on ppc64el is poor
because the ROCm packages don't seem to work on ppc64el anyway. I've
included an explanation about why ROCm was built on ppc64el in the
first place in my rocblas removal request [2].
The rocfft ICE appears to be in a different part of the compiler than
the rocblas ICE, which is a lot more concerning to me than if there
were multiple packages affected by the same compiler bug.
I think we should drop the ppc64el builds of the ROCm math libraries
until we have evidence that they work on that platform. As such, we
need to remove the existing ppc64el binaries.
Thank you for your help!
Sincerely,
Cory Bloor

rocfft built successfully on ppc64el in earlier releases (up to
6.1.2).The failures seen with 6.4.X are caused by upstream build system
changes that now enable HIP device compilation by default.
On ppc64el, HIP device compilation is not supported and leads to
compiler failures. This looks like a regression in how HIP is enabled
rather than an inherent limitation of the architecture.I reported this
issue upstream.
It would be preferable to first clarify or fix the build system behavior
before considering removal of ppc64el binaries.
Thanks,
Trupti
