Please answer these questions before submitting your issue. Thanks!

What did you do?

If possible, provide a recipe for reproducing the error.
A complete runnable program is good.
A link on play.golang.org is best.

Reviewing file:

{name: "ADDSDmem", argLength: 3, reg: fp21load, asm: "ADDSD", aux: "SymOff", resultInArg0: true, faultOnNilArg1: true, symEffect: "Read"}, // fp32 arg0 + tmp, tmp loaded from arg1+auxint+aux, arg2 = mem

What did you expect to see?

ADDSD referenced as using fp64 args in its operation comment, and (nitpick) comes after the ADDSS op code in its respective code block.

What did you see instead?

ADDSD referenced as using fp32 args in its operation comment, and (nitpick) comes before the ADDSS op code in its respective code block.
