ABI voilation

["kanishk rastogi" <kanishk.85@xxxxxxxxx>]

hi all,
I wanted to know if when i specify -O[0-3] flag to gcc does gcc
optimize the code even violating ABI for that specific arch.
If yes can i specify gcc not to violate the ABI ....
I am mostly concerned witht he ABI specification which tells how to
call another function..

regards
kanishk
