This is sort of vague, but in embedded applications that read from or write to particular memory addresses (ie hardware registers), is there any risk of these reads/writes being "optimized away"? Ie, if I have this in the code: int i; *((int *) 0xffee0000) = 5; i = *((int *) 0xffee0000); Are all lines guaranteed to execute with -O, -O2, and -O3? Thanks very much. -Ryan Hajdaj _______________________________ Do you Yahoo!? Declare Yourself - Register online to vote today! http://vote.yahoo.com
