digitalmars.D.learn - instruction set module
- nobody_ (6/6) Oct 11 2006 I might sound really ignorant, so please tell me if I do.
- Jarrett Billingsley (4/10) Oct 11 2006 Do you mean something like std.intrinsic:
- nobody_ (2/4) Oct 11 2006 Yup somthing like that :)
- Jarrett Billingsley (18/23) Oct 11 2006 Well, what instructions are you looking to use? This theoretical module...
- nobody_ (4/20) Oct 11 2006 Thx
I might sound really ignorant, so please tell me if I do. Instruction sets are only accessible throught assembler, right? Would it be possible to write an module which makes some of the more general instructions available through functions? Or is D already fully uptimized in such a way that this would not yield any performance increase?

Do you mean something like std.intrinsic: http://www.digitalmars.com/d/phobos/std_intrinsic.html ?Yup somthing like that :) But those aren't all instructions.. I think ;)

This theoretical module would also be quite platform-dependent, if you're looking to use things like SSE3 or something.. If you'd like, you could write your own functions to wrap the assembly instructions you'd like to use, like: // useless function void Move(int* dest, int* src) { asm { mov EBX, src; mov EAX, [EBX]; mov EBX, dest; mov [EBX], EAX; } }Do you mean something like std.intrinsic: http://www.digitalmars.com/d/phobos/std_intrinsic.html ?Yup somthing like that :) But those aren't all instructions..

I've been looking through all the instruction sets and, yes, it would be
really platform-dependent.
And the most interesting are still to come: SSE4 :)
