Hi!
I have some code do prefetching that I borrowed from src/runtime
// asm_amd64.s
TEXT ·prefetch(SB), $0-8
MOVQ addr+0(FP), AX
PREFETCHNTA (AX)
RET
This compiles fine, $ go tool objdump shows:
TEXT .prefetch(SB) asm_amd64.s
0x4f18e0 488b442408 MOVQ 0x8(SP), AX
0x4f18e5 0f1800 PREFETCHNTA 0(AX)
0x4f18e8 c3 RET
however go vet complains:
$ go vet .
asm_amd64.s:8: [amd64] prefetch: unknown variable addr; offset 0 is e+0(FP)
exit status 1
If I remove addr I get:
$ go build .
asm_amd64.s:8: cannot reference FP without a symbol
Which if the two tools is right?
