Hi!
The gcc trunk and thus gcc-7 contains a fix for the RTL optimizer that
affects powerpcspe [1]. Unfortunately, the patch for this PR (60818)
has not been backported to the gcc-6 trunk yet.
Would it be possible to include the patch to the gcc-6 package?
I'm attaching the patch taken from the trunk, already in the proper
format to be added to the gcc-6 package.
Thanks,
Adrian
