Simplify loop in optimizer's incorporate_inner

I don't know why this splice was originally commented out and not used, but it works.

Micro-optimize the sift_down sub in sorted_keys

Exit early if there are 0 to 2 keys to sort, also pull some variable declarations out of a loop to reduce the number of BOOTInts allocated.

MasterDuke34 what causes indirect name lookups? 13:34
vrurg MasterDuke34: like self."$method"()? 13:36
MasterDuke34 hm, that's the same as ::()? 13:37
vrurg No, it only traverses MRO.
MasterDuke34 github.com/rakudo/rakudo/blob/mast...#L216-L279 is what i'm curious about 13:38
vrurg But then I don't really get your question.
13:39 morayj joined
vrurg I see it used in Actions and Ops. Gimme a sec... 13:39
term:sym<name> is using it. Doc phaser. require. Likely more, if you search by make_indirect_lookup method references. 13:42
MasterDuke34 gitlab.com/jjatria/raku-game-entit...ng-loops.t causes 22k calls to INDIRECT_NAME_LOOKUP 13:43
oh, ^name() perhaps 13:44
vrurg I'd rather suspect @components. .^name should only result in a method lookup. 13:47
jjatria is very interested in this 13:48
MasterDuke34 jjatria: do you need the gather/takes? those are pretty slow 13:49
btw, profiles show your short test file causing 850k deoptimizations, and the long one causing 300k deopts 13:51
jjatria No, I can do away with them. I wasn't aware they'd be a bottleneck
vrurg Last note and back to the main job. I think the most likely cause is token variable -> Actions method variable. 13:52
jjatria My optimisation game in Raku is weak, I was mostly focused on getting it to run, and then to get it to run fast enough. But if it can be faster, I'm very keen

Speed up setup of NativeCall subs and reduce memory usage

When replacing a native sub's stub body with a generated one, we need to remove the scheduled fixups, lest they undo our replacement. The easiest way to do this is to just run the compiler thunk, which takes care of this after dynamic compilation. This however is a very expensive operation as it not only compiles that body but has to create setup code for the lexical scope. This makes ... (6 more lines)

lizmat hmmm.. make spectest failed on 2 files, but these run fine by themselves 21:22
[Coke] we don't have modules.raku.org setup here with Geth, I guess. 21:28

vrurg lizmat: I think they're flappers after all. 22:06
lizmat can't remember having these flap, though :-(
didn't flap when I bumped NQP either
vrurg It's just my experience. Most of the time if something fails when is ran in a bunch but not individually – try it 50+ times and it eventually reveal a problem. 22:11
22:15 hankache left
vrurg I just've pulled the master, t/spec/S17-supply/syntax-nonblocking-await.t fails under spectest. Trying it in a loop. 22:19
lizmat I've just reverted 3b7fef2e7de6bb915da0 locally, then will start a spectest run and look at the result tomorrow& 22:20
