[committed] rs6000: Fix test_mffsl.c effective target check
Commit Message
Hi!
Paul Clarke pointed out to me that I had wrongly used a compile-time check
instead of a run-time check in this executable test. This patch fixes
that. I also fixed a typo in a string that caught my eye.
Tested on powerpc64le-linux-gnu, committed as obvious.
Thanks!
Bill

* gcc.target/powerpc/test_mffsl.c: Change effective target to
a run-time check. Fix a typo in a debug print statement.

(The target clause is redundant fwiw, feel free to remove it).

This selector doesn't make too much sense, since nothing in here
requires vectors at all. p9modulo_hw makes more sense. Except the
name of that should just be power9_hw :-)
The OS can disallow vector insns (MSR[VEC] and/or MSR[VSX]), so
p9vector_hw tests it isn't doing that, and that the hardware is a p9.
p9modulo_hw does only the latter, and we have no reason to check
separately if we can run modulo insns anyway :-)
So please change the test here. And bonus points if you can rename
p9modulo_hw and _ok (in a separate patch of course).
