Subject: gcc.dg/pr44194-1.c: Skip for mmix.
X-Git-Tag: upstream/12.2.0~14335
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fb9e3f7946440e513e897aa2ce45ddd1001d5871;p=platform%2Fupstream%2Fgcc.git

gcc.dg/pr44194-1.c: Skip for mmix.

The test makes sense only for targets that return the
"struct { int a, b, c; }" in registers (not in memory).

Starting a skip-construct is IMHO better than another iteration of
that obscuring "{ ... && { !  mytarget-*-* } }".  New targets can just
append to the list without additional {}:s.  I chose not to "convert"
any of the previous exclusions, as without targets to test, I'd surely
mess up {}-pairs.

A new effective_target would be even better, but such a
check_effective_target_returns_struct_in_memory (or complementary,
_in_registers) would surely have to be parametrized on the size and
type of the returned blob.

Maybe best to restrict to just x86_64, as seems to have been the
original problem target.
