[Bug middle-end/37443] fast 64-bit divide by constant on 32-bit platform

[ajrobb at bigfoot dot com]

------- Comment #2 from ajrobb at bigfoot dot com  2008-09-16 07:15 -------
I changed the summary as it is equally applicable to all 64-bit constant
divides on 32-bit x86 that are already compiled as multiplies on 64-bit x64. It
might be worth implementing as another API call, replacing the 64-bit divisor
with a 64-bit multiplier and a shift count.
