Hi,
This fixes the scan-assembler errors as seen on power9. While verifying
that fix and ensuring coverage, cleaned up some nearby bits as well.
builtins-3.c: Add/update options and skip-if stanzas, this test specifically
targets vsx/power6.
builtins-3-p9.c: Update stanzas to require -mcpu=power9 capability. For better
coverage, added tests here (from builtins-3.c) that have different code-gen
when targeting p9.
builtins-3-p8.c: Update stanzas to require -mcpu=power8 capability.
builtins-3-runnable.c: Update requires to indicate p8vector_hw is required
for running the test. Fixed the do-not-override stanza typo so this test
can run.
builtins-3-vec_reve-runnable.c: Update stanzas to require vsx_hw capability
to run. Removed the skip-if stanza (by direct inspection, this runs OK on
P8,P9, and vsx_hw requirement prevents run attempts on earlier systems).
Sniff-testing across systems looks good.
Will kick off a regtest in clean environments shortly.
OK for trunk? (and gcc-7 backport)?
Thanks
