发帖数: 582 | 4 After I use gcc –S to get the assembly output:
1. Is there a good online manual to help understand the output assembly file
, its structure, its syntax?
2. How can I check the details about a specific assembly instruction, for
example “leal”? under ubuntu, we can use “man fork” to check the details
of fork. But is there a similar way to check the assembly instruction?
Thanks a lot. | b******n
发帖数: 592 | 5 why do you want assembly output when you don't even understand it?
If you want to learn assembly, this is not a good way. You can do better wit
h some pdf or online tutourials.
And you need to learn how to use google.

发帖数: 6806 | 6 gcc outputs at&t syntax by default. you may choose intel syntax by using
option -masm=intel. that is, if you understand i386 assembly with intel
syntax.
the difference is documented in GNU as (the assembler). use "info as" to
read it.
