Has anybody tried 64-bit x 32- bit signed/unsiged integral multiplication function giving 64-bit result and 64-bit/16-bit division or 64-bit/32-bit division in assembly?


I was able to do it activating 64-bit support and using intrinsic multiply functions LL_mult as mentioned in 56800e Targetting Manual. But since they add lot to code size, I need some compact functions in assembly. I hope somebody could have tried and would help me out in writing such function.
