New J.A Compiles

[JVMerlino]

Hi Jim,

I've almost entirely stopped working on Myrddin, but I wouldn't complain if you made one of your magic compiles that are 10-20% faster than mine.

Many thanks in advance, but certainly not expecting you to spend your time on a (nearly) dead engine.

My goodness you did a LOT of stuff. I'll run a gauntlet and let you know the results.

Thank you SO MUCH, Jim. You're a wonder....

Hi again, Jim,

Your build is definitely faster than mine. For example, from the initial position, with one core, your build gets to depth 20 in 43.98 seconds, getting 2.27M NPS. My build needs 51.64 seconds, getting only 1.97M NPS. Clear improvement!

However, and I hate to say it, and I'm still trying to track down the issue, I think there's a problem with Gaviota egtb access.
For this position, for example:
5k2/pp3N2/5K2/5B2/8/8/8/8 w - - 15 1

My build gets:

Huge slowdown!
Any ideas?

Thanks again for all of your work for Myrddin, and the community!

Dear Mastero Jim,

Thank you for compiling Alexandria.

There seems to be quite a difference in size of your compiled 7.0.14 bmi2 (1,654 KB) vs the official compile 7.0 bmi2 (5,246 KB). I'm curious: is something amiss?

Best wishes,
Koh, Kah Huat
