Hi,
I want to know if the intel compiler has an intrinsic function to compute the higher part of the product of two 64-bit integers on 64 bits processors. Visual c++ has the function _mul128 which perform this operation.
And for intel c ++ on linux or macos X ?
What is the similar intrinsic functions ( or two if needed) on xeon to _m64_xmah available on itanium in order to perform the multiplication and the addition ?
Thanks,
Mickael,
