I plan on doing more regression testing with different versions and
builds of GCC (at least 5.x, 6.3, and 7.2 in addition to 6.4) to see
if this is a regression or where the bug was introduced. It would be
much better to find the root cause of this breakage and include a
patch to gcc than to work around it with a specfile.
Also, I have so far not run into any issues with ppc64 BE with
- -fno-inline-small-functions but that could be masking a more subtle
compiler bug. It's all quite scary, to be blunt... but such is life
with very untested code... don't think anyone has ever used
- -mabi=elfv2 with ppc64 before.
