That's not a good way to learn assembler. A compiler adds lots of things to the assembly code that makes life simpler for the compiler itself but will get you confused in no time...
It's better to search a few good books about x86 assembler to start learning it.
Also, in case you didnt know, every family of processors uses its own instruction set / architecture. So if you plan on learning assembler to lear program microcontrollers (like pics) then you shouldnt be learning x86 (PC) assembler cause its totally diffirent.
