Can you remind the exact changes that -profiling does? There was some optimization that -profiling didn't do, but -g2 should not affect any optimizations? I recall you said that reading through the output code files with -profiling was slightly easier than with -g2, but wouldn't -g2 be better for users that only cared about Firefox/Chrome profiler results and only need function names intact?
