Go的汇编程序的条件跳转指令是什么？

Question

Go's 6a assembler has conditional jump instructions:

JCC
JCS
JCXZL
JEQ
JGE
JGT
JHI
JLE
JLS
JLT
JMI
JNE
JOC
JOS
JPC
JPL
JPS

But how do they map to x86 conditional jumps?

Answer 1

I'm answering this so I don't lose the information, and so other people don't have to go through the same sleuthing game as me. Looking at optab.c and the x86 jumps we can match up the instruction encodings to solve the puzzle.

JCC     JAE
JCS     JB
JCXZL   JECXZ

JHI     JA
JLE     JLE

JOC     JNO
JOS     JO
JPC     JNP, JPO
