MPLAB C32 compiler optimisationPosted by ulmus on February 21, 2012 Do you know about something i have to remember when compiler optimisation is used? I have a working big project with lots peripheria and tasks, now i turned on optimisation and.... my app is not working as it should :( RE: MPLAB C32 compiler optimisationPosted by MEdwards on February 21, 2012 Not an easy question to answer, but the kernel should not have a problem with optimization. Normally either the compiler optimizer has bugs, running the code faster shows up weeknesses in your code (time dependencies), you are relying on code that the compiler rightly thinks is not doing anything and removes (using a null loop for a delay for example), but most commonly you are missing volatile qualifiers on a variable. RE: MPLAB C32 compiler optimisationPosted by ulmus on February 21, 2012 Yeah, i think so, that i am missing somewhere 'volatile' qualifier. I just have asked if there is something more i have to know and remember. Thanx for help. I must now dig deep in my project to find that buggy variable :(
