Is not posible to find all the buggy casts (between unsigned and signed ints) using this compiler flags?
I'm actually not sure.
Anyone did try it?
Once in a blue moon, yes. However, the number of warnings was so overwhelming that it felt to laborious a task (in particular considering that often you need to find your way backwards from the C code to the slang code and that inlining makes the problem worse).
Actually, I would not mind putting some time into this if there was a way to organize the work such that any changes I identified could be properly vetted. I recently came up with a way to browse generated C and inlined C code in Squeak (*), which makes the problem seem considerably less intimidating. I've also done the 64 bit updates for some plugins (OSPP et al), so I have a passing familiarity with the issues.
The suggestion of using -pedantic is a good one, but I'll note that there are compiler warnings generated simply by compiling the VM on a 64 bit host. Making those warnings go away would be a good first objective.
