Full Discussion: C multiplication with GCC
Top Forums Programming C multiplication with GCC Post 302544700 by pheonix on Thursday 4th of August 2011 04:07:33 PM
Old 08-04-2011
Thanx for reply, however maybe title a little misleading? I am trying to write "C"
code, usable by different processors. On an Intel processor using GCC or Clang
I wish to have:
Code:
(int)(((unsigned long long)result * (unsigned)2290649225) >> 37);

to look like:
Code:
mov $2290649225, %eax
imul (%ebp)
mov %edx, %eax
shr   %5, %eax
instead of:
imul $-2004318071, %edx, %esi
mov $-2004318071,%ecx
mov (%ebp), %eax
mull %ecx
lots more code
shr %5, %eax

if I use the second "C" language code:
Code:
(int)(((unsigned long long)result * (unsigned)1145324613) >> 36);

which is half of $2290649225 i get the first compiled result.
On i386 vs x86_64 the above codes should only differ in extension "l""d", but I believe the exact register reference with get you though both as "asm".
Again, I am trying to write "C" code, so I guess is there a way to tell compilers that (unsigned)2290649225, (uint32_t)2290649225, 2290649225U is an unsigned 32-bit number so shorter code is used?

Thanx Corona688! You got me in the direction I needed! Had me explain so understood what GCC might think? Strange that the 31st bit of a constant does this. Apparently the int result gets converted as long long then unsigned long long.
Resolved!
Code:
(int)(((unsigned long long)((unsigned)result) * (unsigned)2290649225) >> 37);

Sincere thanks! Pheonix
