    I use der8auer paste. Kind of cool to see how much effort he puts into it. $6 a gram seems like a bargain now.

    Because 3dnow registers used the MMX area and SSE was had its own.

    Nope, they are not spilled over to the stack because compiler is storing results on the stack because array is kept there;) So in other...

    The OoO may be opaque to the compiler. Compilers still produce code in ways that help the OoO engine take advantage of register...

    You took this this out of context. I said the compiler is reusing the same registers over and over. example code int xvals[8] =...

    They are aliased by name. If there are no dependence between them they can coexist at the same time with the same name and only the last...

    That is not exactly true, is it? I mean register file still has entries and limited number of these, of course much more than...

    Before pentium registers were exact memory locations. Fixed size. Smaller operands within the registers were mapped to lower bits...

    No they mapped AVX over SSE which was the reason I expounded above for the slow down and extra flush issues. They later solved this as...

    PS the pdf you linked to only goes to Westmere EX. This is like saying back in the day intel declared that the registers will be so and...

    Are we in a modern thread talking about Lakes or back in y2k?

    Actually it would be an 128b lane. In AVX256/512 you can't operate across a lane. You can transfer data across them but that's a special...

    Myopic! Register has evolved to a special type of operand. They are renamed on the fly to different memory/port areas. There isn't a...

  • Schmide replied to the thread Discussion Intel Meteor, Arrow, Lunar & Panther Lakes Discussion Threads.

    In a way now you don't really have registers, you have ports. Everything is out of order and pipelined. This doesn't mean there aren't...
