Christoph Franck said:
I have a nice example here of very simple, legal C code that will break completely when run through the IAR ARM compiler at the highest optimization setting. Just because it's "legal" C code is no guarantee that it'll actually run under any circumstances. Yes, compilers do have bugs - but, Presumably, you have checked that it's not a bad assumption in your code that just happens not to fail for all but the highest optimisation setting? Simply dismissing optimisations out-of-hand as "stupid" did not suggest that the OP had fully grasped the issues... |
