Okay. The following change allows all of the struct-layout-1 tests in gcc.dg
under i686-apple-darwin9 with current gcc trunk...

Oh, I see the problem.
We generate:
/* { dg-options -mno-mmx { target i?86-*-* x86_64-*-* } } */
/* { dg-options -fno-common { target ... *-*-darwin *-*-mingw32*
*-*-cygwin* } } */
However, x86 darwin, mingw32 and cygwin* matches both lines. Since dg-options
don't concatenate, latest match simply overwrites all previous matches.
So, these targets simply overwrite -mno-mmx option.

Uros,
I'll retry the testcase tonight with your committed changes.
http://gcc.gnu.org/ml/gcc-cvs/2008-11/msg00353.html
I do recall that I tried...
* { dg-options -mno-mmx { target i?86-*-* x86_64-*-* } } */
/* { dg-options -fno-common -mno-mmx { target ... *-*-darwin *-*-mingw32*
*-*-cygwin* } } */
and that causes many more tests in struct-layout-1 to fail.

(In reply to comment #15)
I do recall that I tried...
* { dg-options -mno-mmx { target i?86-*-* x86_64-*-* } } */
/* { dg-options -fno-common -mno-mmx { target ... *-*-darwin

and that causes many more tests in struct-layout-1 to fail.
This should work now. You have to remove inclusion of mmintrin.h and
xmmintrin.h for -mno-mmx, otherwise you will get the same problem as shown in
Comment #9 on targets where -msse2 is the default (this includes x86 darwin).
Fortunatelly, this is pure testsuite problem, see Comment #13.

--- Comment #12 from ubizjak at gmail dot com 2008-11-14 07:40 --- (In reply to comment #8) Let me know if I need to provide anything else to debug this. Again, this test case passes completely if I delete the second line of t027_test.h. The problem is, that %mm0 register is accessed in check2601(), as can be seen from t027_y.s assembler dump. This access blocks stack registers in check2601va(), so the check fails at this point. My patch disables all access to MMX registers, so V1DImode should be handled by generic moves. However, IIRC darwin doesn't use MMX registers to pass function args/return values. From t027_y.s dump that you provided, it is evident that check2601() returns its structure with only v1di member in %mm0. Is this OK? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38099
