First debugging optimized code May be hard, or not. The compiler may combine lines, eliminate code that does not thing, not perform calculations that are not used, and other neat tricks. That means the code may not single step or take a break point where you need it.
Second code that does not work when it is optimized may still be the coders fault. Just because the code works that does not mean it is correct and bug free. That means optimizing, adding code or variables, anything may make it fail. newbies are very quick to blame the compiler. Third compiler bugs they do exist. If you "do not want" take the time to send it to the manufacturer then tough. Unless the company has a reputation for not fixing bugs. Most companies will accept bug even if you support has expired. Modifying the compiler output to fix a bug to me would be the final act of desperation. Making the same fix after each compile. Documenting it to be sure you can still do it next year. Or the next guy can do it. |
