Sorry for replying late (I am in holiday during these days, and no any x86
environments). Your patch is OK to me. But I guess, providing more details will
be helpful for other members:


For ia32, gcc includes intel common environments (e.g. linux) and mac
environments. Size of long double can be get by "echo | gcc -m32 -dM -E - |
grep LONG_DOUBLE", linux is 12, mac is 16.

For long double alignment can be get by building the c code: "int
alignof_long_double = _Alignof (long double); long double ld = 1;", linux is 4,
mac is 16.

For most archs, size of long double should be 16, so checking the special case
should be OK (check intel common ia32, and remove "{ target { ! { ia32 } } }").
If any other archs report failure, we can add another switch macros just like
this patch has done.


Thanks.
