Hello,

I was able reproduce this issue on ppc64el.
I will look into this and update you soon.


Thanks,
Trupti.

Hello,

The failure is caused by unconditional HIP device compilation being
triggered during the build, even on ppc64el systems without ROCm GPU
support. This leads to compiler failures in the HIP/clang device path
and breaks the build at configure time.

This previously built because earlier versions did not enforce HIP
device compilation in the same way; recent changes in the build system
now attempt HIP device compilation unconditionally.

I have reported this issue upstream to the rocFFT
project(https://github.com/ROCm/rocFFT/issues/651) so it can be
addressed properly in the build system. I will update this bug once
there is feedback or a proposed fix from upstream.


Thanks,
Trupti

Hello,

The build failures of rocfft on ppc64el are caused by a crash in
clang/LLVM when compiling HIP code.
Specifically, compiling HIP client test sources triggers an internal
compiler error in the LLVM PowerPC backend during code generation.
This is an upstream toolchain issue and not a functional problem in
rocfft itself.

The compiler crash has been reported upstream and is tracked in the LLVM
issue tracker: https://github.com/llvm/llvm-project/issues/168727

I tested a targeted workaround on ppc64el by disabling HIP client tests,
while keeping the core rocfft library unchanged. With this change,
rocfft builds and installs successfully on ppc64el.

Given this, would it be acceptable to apply a targeted workaround that
disables HIP client tests on ppc64el, instead of removing the ppc64el
binaries at this stage?


Thanks,
Trupti

Hi Trupti,

It depends. For example, it's fairly typical to temporarily disable
individual tests, pending upstream resolution.

Could this be an option here? Is the internal compiler error triggered
only on some code paths that could be temporarily be disabled with a
patch, or is this an issue closer to the core?

Disabling all tests would need a good justification, but I'm not sure
it's present here. If the package's own tests fail to build, then I
don't see what good keeping the library would do, as anyone else
building their own code against it would (presumably) run into the same
error.

Another approach could be to force the use of an older LLVM. Cory's
comments on #1118435 [1] seem to suggest that this is possible, by
adding the older LLVM to Build-Depends and adapting d/rules to it.

Though a bit of work, that might actually be the simplest solution to
keeping ppc64el rocblas, hipblas and rocfft.

Best,
Christian

[1]: https://bugs.debian.org/1118435

prefer not to maintain ppc64el packages, because new issues might still
pop up and we're back to square one.

From experience, I myself tend to be very conservative about what
architectures to support.

Best,
Christian

In my experience, bugs triggered on one architecture have a high chance
of being present but silently hidden on other architectures, and thus
keeping a program running on widly different architectures is a net gain
for both code quality and robustness of a program.  So I tend to be
liberal with which architectures to list in the Architecture field in
d/control, and only limit it if the alternative is not sustainable.

I also try to ensure the build will test the generated binary before
calling the build a success, to reduce the risk of broken binaries
making it into the archive.  There is no advantage from a release
critical bug in a architecture where no-one can use the package anyway,
keeping the package out of the next stable release in Debian.

Yes, agree with you.

Thanks,
Trupti

Hello Christian,

Thank you for the suggestion, and apologies for the delayed response.
I went through Debian bug #1118435, and as suggested, I tried building
rocfft with an older LLVM version (LLVM 19).

With clang-19, the current segmentation fault no longer occurs; however,
it results in the following error:

6.4.3/library/src/device/generator/../kernels/../../../../shared/rocfft_complex.h:34:9:
error: _Float16 is not supported on this target 34 | typedef _Float16
rocfft_fp16; | ^ 1 error generated.


I tried to disable the code that triggers this error but I think I am
missing something

Thanks,
Trupti
