Debugger execution statistics #375

Open svaarala opened 9 years ago

svaarala commented 9 years ago

Useful execution-related statistics:

Cumulative opcode execution count (with and without debugger Evals etc)
Cumulative statement count (not easily available)
Native call count
Ecmascript call count
setjmp count
longjmp count

The easiest statistic available would be cumulative opcode execution count, with debugger executed opcodes excluded.

Statement count would be very difficult I think, you could probably count lines easily (with some potential for inaccuracy, and not a very useful statistic in the case of, e.g. minified code), but counting at the statement level would need, at the very least, instrumentation from the compiler.
