[Mono-dev] Profile with optimizations

[Alex Rønne Petersen]

What *might* work is calling mono_jit_parse_options () from your
mono_profiler_startup () callback. Something like:

    mono_jit_parse_options (1, (char*[]) { "-O=-all" });

Replace `-all` with whatever you need. I think your callback should be
called late enough that this'll override user flags (if that's really
what you want to do).

Alex
