I'm calling this one invalid. We've got:
eax __d0 early clobber
ebx pic
ecx __d1 early clobber
edx __s input
esi __res early clobber
edi __d2 early clobber
ebp frame pointer forced by alloca
The problem with the "=&g"(__d3) operand is that (1) there are no more
registers, and (2) there is no memory that doesn't conflict with the
(*(struct { char __x[0xfffffff]; } *)__s) input, and thus there is no
memory that can satisfy the early clobber.
I'm not 100% certain why this was accepted before gcc 4, but I'm not
curious enough to go looking.
