debugging tmpdir-gcc.dg-struct-layout-1 failures

[Jack Howarth]

Eric,
    I filed a PR29090 for the gcc.dg-struct-layout-1 failure of

T(94,struct atal16{}a;,)

...out of the set of failures I see. I noticed that in the 
assembly from struct-layout-1_y.s, the follow occurs...

.comm _a94,1
	.stabs	"a94:G(0,1)=ar(0,2)=@s64;r(0,2);0;01777777777777777777777;;0;04;(1,1)",32,0,1,0
	.stabs	"long unsigned int:t(0,3)=@s64;r(0,3);0;01777777777777777777777;",128,0,0,0
	.stabs	"test_va:G(0,4)=k(1,4)",32,0,9,0
	.literal8
	.align 3

Does that match what you see in radar for the lack of aligned uninitialized variable
support on Darwin PPC at -m64? If so could you append the radar number for that
bug to my PR so they are marked as the same bug?
                  Jack
ps I assume there are no fixes in-house at Apple for this one yet?
