Alexandre Oliva April 14, 2022, midnight UTC 
[sorry, I failed to add [PATCH] to the subject of the two previous patches]

Though -mpower9-vector makes float128 support possible, some target
systems such as vxworks disable float128 types by default
(TARGET_FLOAT128_ENABLE_TYPE is defined to 0), so explicit -mfloat128
is needed to enable it, and then the fact that the full support may be
unavailable is flagged with a warning.

This patch adds -mfloat128 and prunes the warning in two tests that
use the _Float128 type without explicitly enabling it.

Tested on x86_64-linux-gnu x ppc64-vx7r2 with gcc-11.  Ok to install?


for  gcc/testsuite/ChangeLog

	* gcc.target/powerpc/pr82748-1.c: Add -mfloat128 and prune its
	warning.
	* gcc.target/powerpc/pr82748-2.c: Likewise.
