Hi , I am a newbie in compilers, recently came across a problem that when i try to use optimization options( -O_ ) during compilation , i do not get the asembly for the processor that i am porting gcc to. Is there a simple thing i am missing somewhere? Secondly, are there some macros i need to define in regard with optimization. Kindly clarify the doubts and provide any other basic information that i need to have regarding optimizations, specifically peephole.
