I find a doc https://golang.org/doc/asm#unsupported_opcodes, it says "One is to update the assembler to support that instruction". But I can't find any further doc about this. I also find a previous CL which add some instruments https://go-review.googlesource.com/c/go/+/183225, but I don't fully understand the patch, especially the asm6.go part.

I'm not aware of any other documentation on the assembler internals.

If you have a specific question we can try to answer it.
