buggable 🎺🎺🎺 It's time for the monthly Accidental /win Lottery 😍😍😍 We have 2 ballots submitted by 2 users! DRUM ROLL PLEASE!... 00:00
And the winning number is 10! Congratulations to samcv, nine! You win a roll of duck tape!
brrt .tell lizmat gc documentation here: github.com/MoarVM/MoarVM/blob/mast...c.markdown 13:48
yoleaux brrt: I'll pass your message to lizmat.
lizmat brrt: thanks! 13:49
yoleaux 13:48Z <brrt> lizmat: gc documentation here: github.com/MoarVM/MoarVM/blob/mast...c.markdown
brrt :-) 14:16
lizmat brrt: opinions about github.com/MoarVM/MoarVM/pull/882 ? 15:44
brrt i was actually looking through that 15:50
i wanted to give that a proper review, but it looks alright
lizmat .ask jnthn is github.com/MoarVM/MoarVM/blob/mast...c.markdown still up to date, or could it use an update / refinement ? 15:51
yoleaux lizmat: I'll pass your message to jnthn.
lizmat brrt: so you're ok with merging ?
brrt ehm. well, if it passes the test suite, then my hand-review is not likely to contribute much 15:54
but if it's all the same to you please give me 15 more minutes :-)
lizmat yeah, I can wait 15 minutes
:-)
brrt so I learned is that we actually know a lot about the templates that we're not currently exploiting 16:06
lizmat is intrigued
brrt ok, for instance, we're computing the operand types and sizes at runtime 16:07
we don't actually need to do that
and we're inserting casts
also at runtime
and that as well can be eliminated, since we know (per oplist) the proper size of all things going in 16:08
and types
lizmat that sounds like an interesting optimization opportunity ? 16:14
brrt well, the result of it will probably be very minor since it is compiler internal 16:18
what it does do however is make it much easier to assert that a given template actually is correct 16:19
that is kind of a valuable thing, I think
lizmat indeed :-) 16:20
brrt I reviewed and left comments on a bunch of *very* minor things 16:50

Used fixed size allocator for hashes. Nice speedup for table expansion

Factor out our hashing function and speed up hashing flat strings

Factor out our string hashing code into one function which adds three graphemes and another one which finishes the hash adding 0, 1 or 2 further graphemes.
This makes it easier for us to provide faster hashing for flat 8 or 32 bit strings by not having to use a grapheme iterator.		 23:40
