"ADDL runtime.m0+8(SB)(BX*4), AX" is accepted by the 386 assembler, but denied by the amd64 assembler. With error message,

Building Go cmd/dist using /usr/lib/go-1.6.

Building Go bootstrap cmd/go (go_bootstrap) using Go toolchain1.
asm: invalid instruction: 00175 (/home/local/SPREADTRUM/ben.shi/Desktop/go-old/src/runtime/asm_amd64.s:74)	ADDL	runtime.m0+8(SB)(BX*4), AX

go tool dist: open /tmp/go-tool-dist-417590703/runtime/asm_amd64.o: no such file or directory

But there is no error if the instruction is added to src/runtime/asm_386.s
