[cmake-developers] New RelWithDebInfo flags?

[Ben Boeckel]

Hi,

I just discovered today that it looks like GCC 4.8 shipped with a new
optimization level:

   -Og Optimize debugging experience.  -Og enables optimizations that do
       not interfere with debugging. It should be the optimization level
       of choice for the standard edit-compile-debug cycle, offering a
       reasonable level of optimization while maintaining fast
       compilation and a good debugging experience.

Would using this (if available) rather than -O2 in RelWithDebInfo
configurations be something developers would want?

Mailing list thread about the patch:

Thanks,
