There is builtin __uint128_t type recognized by gcc [reportedly] since
3.1, so that why does one have to clobber it with typedef? Could you
generate assembler listing for following snippet?
unsigned long long foo(unsigned long long a,unsigned long long b)
{ return ((__uint128_t)a*b)>>64; }
I mean run 'gcc -O3 -S file.c' and post file.s. Well, you might have to
add whatever appropriate platform flags to gcc, e.g. -mabi=[n32|64] and
-mips4.
Out of curiosity. What CPU is it? Which OS?
