Test gcc.dg/asm-hard-reg-5.c might fail on powerpc64 with:
gcc.dg/asm-hard-reg-5.c:27:3: error: register 5 for operand 0 isn't suitable
for data type
gcc.dg/asm-hard-reg-5.c:34:3: error: register 5 for operand 0 isn't suitable
for data type
For powerpc64le there exists no CPU without altivec support which is why
-maltivec is implied. For powerpc64 this does not hold which is why for
this test -maltivec must be specified, or the other way around must be
skipped if there is no altivec support.
I'm not entirely sure whether I grasped all the nitty gritty details of
rs6000_target_modify_macros and whether I should use target selector
powerpc_vsx or as done by this patch powerpc_altivec_ok. Any comments?
Tested on cfarm121 where we have, now:
PASS: gcc.dg/asm-hard-reg-5.c (test for excess errors)
PASS: gcc.dg/asm-hard-reg-5.c scan-assembler-times foo\t5 2
