Using longlong.h for wide-int.cc failed on 32-bit x86 because the 64-bit
x86_64 patterns were being defined for i386 too. Specifically:
#define umul_ppmm(w1, w0, u, v) \
__asm__ ("mul{q} %3" \
: "=a" ((UDItype) (w0)), \
"=d" ((UDItype) (w1)) \
: "%0" ((UDItype) (u)), \
"rm" ((UDItype) (v)))
was being used if __i386__ was defined.
Tested on x86_64-linux-gnu and i686-linux-gnu. I put a:
#if defined (__i386__)
#error FOO
#endif
trap in the old block just to make sure that libgcc wasn't using any
of the other macros. Approved by Richard B. on irc and applied.
Thanks,
Richard
