--- Comment #11 from Manolis Tsamis <manolis.tsamis at vrull dot eu> ---
Hi all,

I will also go ahead and try to reproduce that, although it may take me some
time due to my limited experience with HPPA. Once I manage to reproduce, mo=
st
f-m-o issues are straightforward to locate by bisecting the transformed
instructions.

> I think the key object is Python/compile.o, but not certain yet.

In this case the dump file of fold-mem-offsets
(-fdump-rtl-fold_mem_offsets-all) could also be useful, as it contains all =
the
information needed to see whether a transformation is valid. If it would be
easy for anyone to provide the dump file, I could look at it and see if
anything stands out (until I manage to reproduce this).

Thanks,
Manolis=
