Using Codewarrior Eclipse IDE version 10.6. Programming a 56f8367 with the USB Tap.
Due to a legacy code issue, I have a soft limit on the number of blocks I can use for programming space.
We recently just passed that mark. Now, I am sure there are many things I can do in the code to make it more efficient, but I tried to play around with the compiler optimization settings to see how much this would buy me.
Under the Optimization menu, I changed it to Size and Optimization Level 1. This dramatically decreased the size of the code and would be a great help. I was also able to load and test this and successful tested a large set of the functionality.
However, I pressed my luck and increased the optimization level to 4. When I did this, the program no longer ran. It would compile, and I could load it into the unit, but I would immediately crash. It looks like it crashed on a long division, if that helps at all.
Anyway, I decided that I would just back off back down to Level 1 as it would have been more than enough. However, THAT stopped working too. It would crash in the same way. I tried programming a different unit, I even tried a different project (the same code, with just a few different #defines) and none of them work either. Even if I turn Optimization Level to "Off" and set it to "size" my program still crashes in the same way. The only way I can get it to work now is to set it to "Speed" and "Off."
I am working with a repository, so I have another guy who can check out the same exact version of code I am working with, and he is able to compile with Optimization Level 1 and Size.
It seems like setting it to Level 4 broke my ability to optimize it at all. . .I can even set it to Size at all!
I am wondering if there is something that Cleaning the project does not actually clean where something about the optimization is getting stored which is why I am no longer able to optimize successfully even though I was able to do so before.
Any ideas?
