The FP pseudoreg has been dropped from assembly output (on tip). All
offsets are from SP. On previous versions the assembly output reported the
base register as FP but the offset was from SP.
See https://github.com/golang/go/issues/19458 and referents.

The assembly documentation in golang.org/doc/asm.html is accurate in this
respect, I believe. By "in this respect" I mean both what the assembler
accepts and interprets and what is intended.
The compiler output for -S has not been brought to the same standard and
may well use SP when FP would be m
I hope someone else knows. I've also been confused by the difference
in the offsets in the past, and when I asked about it I was told that
the output of go tool compile -S is just different than what you write
by hand. Unfortunately I don't think that the -S output is documented.
You might have to
