Speed up the far back end of the JIT #6752

Open pkukol opened 7 years ago

The "Emit code" and "Emit GC+EH tables" phases of the JIT take up to 15% of total compile time which seems pretty high (this is esp. critical for the MinOpts path). Look for opportunities to speed these up.

Have we done any deeper analysis of this s.t. we can tell roughly where this time is going?

Is dotnet/coreclr#9231 related to this?

Yes, it was related to this issue.

As with https://github.com/dotnet/runtime/issues/6751, it would be interesting to re-evaluate this considering many improvements have been made since 2016/2017.
