Easy to read Golang assembly output?

Question

I\'m interested in examining the x86 assembly output of the standard Go compiler to see if my code is really being converted into reasonably efficient assembly code; hopeful

Answer 1

I don't recommend using the output of -S as the Go linker can change what gets written to the object code quite a lot. It does give you some idea as to what is going on.

The go assembler output is rather non-standard too.

When I want to do this I always use objdump which will give you a nice standard assembler output.

Eg for x86 / amd64

objdump -d executable > disassembly

And for ARM (to get the register names to be the same as Go uses)

objdump -M reg-names-raw -d executable > disassembly
