- aw1621107 4y agoHuh, first time I've seen that instruction. Thanks! Does seem that it converts its arguments first, though? > The FIMUL instructions convert an integer source operand to double extended-precision floating-point format before performing the multiplication. (Via https://www.felixcloutier.com/x86/fmul:fmulp:fimul https://www.felixcloutier.com/x86/fmul:fmulp:fimul) In addition, I thought compilers tended to avoid the x87 FPU registers nowadays?
