The powerpcspe backend has been deprecated in GCC 8 and removed during GCC 9
development. See corresponding mailing list threads[1,2,3] for details.

The consensus here seemed to be to close them:
https://gcc.gnu.org/pipermail/gcc/2020-May/232591.html

So, I'm closing this.

Yes, but AFAIK none of the PRs specific to powerpcspe have been closed so far.
And, personally, I'd like them to stay open for another release cycle in the
hope Andrew would actually revive the target this year. But it's up to gcc
maintainers to decide, of course.

Looks like the powerpcspe target is being removed now...

AFAICT, it's still the case for powerpcspe target even on trunk (as of
r259982). While gcc apparently doesn't generate SPE instructions for both
attached testcases anymore, I've just easily reproduced the issue w/ our
internal codebase.

Is this still relevant now that powerpc and powerpcspe have been split into
separate targets?

This looks like an option parsing problem.

Building with the deprecated -mspe=no option suppresses all SPE instructions,
which is what I expect/want. There seems to be no need to specify -mabi=no-spe
if -mspe=no is set.

-mno-spe seems to be broken.
