[LLVMdev] Default implementations for __ashldi3, __ashrdi3, __divdi3, __udivdi3, etc?

[Daniel M Gessel]

Are there existing "generic" implementations for these functions under  
the same license as LLVM? By generic I mean C or IR that doesn't use  
any particular HW intrinsics.

I read up on divides in Knuth's Seminumerical book, but decided to use  
base-2 long division on the first go-around for simplicity. I know  
it's not very efficient and I'm looking for shortcuts to something  
better.

Pointers to divide algo's could also be of use.

Thanks,

Dan
