FLD is missing in x86 about golang-asm HOT 6 CLOSED

Sometimes the developers don't implement an instruction if its superfluous. Lemme find you an example of loading a float, brb.

from golang-asm.

I'm also trying to work-around this by using XMM registers instead, but getting:

invalid instruction: 00026 (<unknown line number>)      MOVQ    $(DI), X0

from golang-asm.

For more context: I'm trying to process float64-s from one array and put the result into another.

from golang-asm.

You should be able to MOVL (32bit) or MOVQ (64bit) a float to one of the X* registers, from another register.

And heres an example of some floating point operations.

https://github.com/go-interpreter/wagon/blob/master/exec/internal/compile/backend_amd64.go#L818

from golang-asm.

Heres an example: 3c8ad97

from golang-asm.

Thank you! I've managed to do it (with your help). I'll publish the code, soon. Though it is ugly (and slow), but still works as a proof of concept.

UPDATE: Just if somebody else is struggling the same issue, then here's a one more example: https://github.com/xaionaro-go/rpn/blob/master/implementations/compile/op_amd64.go#L250

from golang-asm.
