-m and -m -m respectively ask the compiler to print and explain its inlining and escape analysis decisions. This is very useful. But almost always I am interested in inlining or in escape analysis, but not both, so I end up grepping through the output.

We should keep the existing flags, since they are used in documentation and blog posts the world over. But I'd like to add new flags to print just inlining or just escape analysis. (-ml and -me?)

Opinions? Bikesheds?

I usually prefer to inspect both at the same time to understand where things can be optimized. And wrote a separate tool for visualizing both. So maybe the better solution would be some nicer integration to editors rather than introducing new flags? Although, since the -m is preserved it might an orthogonal concern.
