Re: [drlvm][jit][abcd] HARMONY-1788 Inequality graph generation from HIR
Hello Egor,
I'm almost too embarrassed to ask, but if I started looking at your
ABCD code now, would it still be useful?
My "one week" of pressing tasks turned into over a month. Sorry.
Naveen

It actually *is* useful!
I have been busy with stability issues during this period, thus made
no progress in ABCD since my last update to HARMONY-1788. I want to
finish this work not later than January. If you have time to do it
faster, you can take it. I will be fixing Jitrino.OPT here and there
for a while yet...
