Probably a good idea. I don't know enough about anything but Sparc
to comment. Sparc32 is fine, as the aggregate return pointer is
hidden in a special stack slot.
Sparc64 is not, as aggregates larger than 32 bytes are returned via
an in-band argument register pointer just as on Alpha. This should
not hold up egcs 1.1, as Sparc64 is not really supported well at the
Incidentally, we should have a variant of one of the thunk tests that
has a larger class size. The existing tests have size 16 on sparc64,
which would be returned in registers and so not show the bug.
