timotimo in the optimizer, would i have to find_lexical("Signature") to access the $!params of a Signature? i would assume if Signature was redeclared lexically, i'd still get the Signature from core there, right? but just writing Signature instead doesn't seem to work. 07:51
07:52 dmol1 left
sorear if you do find_lexical("Signature"), make sure you start the search from the correct place so you get CORE::Signature and not COMPILING::Signature 07:53

08:09 berekuk joined
moritz diakopter: there's a subdir for build scripts in the p6eval repo 08:10
cognominal timotimo: or the plan is maybe to eventually compile rakudo in rakudo?
s/in/with/ 08:11
timotimo i'm not sure how to start my search at the CORE block; the previous code to see if some lexical comes from the core is just to look if there's a !CORE_MARKER in it ...
oh, i suppose i can just walk the block chain for a !CORE_MARKER to exist
and then just save that away
08:21 kaare_ joined, crab2313 joined 08:22 frdmn joined
moritz timotimo: rakudo would benefit from an nqp-level optimizer 08:22
for build times, and also because Actions, Grammar and World are written in NQP 08:23
and the meta model
08:23 berekuk left 08:26 domidumont left 08:27 arlinius joined
timotimo mhm 08:29
especially all those negative numbers having to be make-int + negate-int :P
moritz wwwhat?
timotimo is the prefix:<-> operator already inlined for nqp? 08:30
moritz a -1 in nqp produces a QAST::IVal.new(:value(-1)) 08:31
so no separate call to nqp::neg_i or so
timotimo ah, that's nice. 08:33
i seem to recall in rakudo it used to be non-inlined, but that must be because you can override - in rakudo but not in nqp?
moritz iirc jnthn++ improved the codegen a bit when he introduced PIRT 08:34
timotimo: probably
timotimo what is PIRT?
moritz the stage after QAST 08:35
$ ./perl6 --target=optimize -e 'say -1' > optimized 08:36
$ ./perl6 --target=ast -e 'say -1' > naive
$ diff -u naive optimized
08:37 ivan`` left
moritz shows that the call is constant-folded, but that we lose the polymorphism of the integer literal 08:37
08:37 tgt joined
moritz if somebody is looking for a fun little project in the optimizer, that would be a nice thing to fix 08:38
timotimo oh, i know it by the name "optimizer" ;) 08:39
hm, what's the use in getting that back?
08:40 berekuk joined
moritz if you write code like my int $x = 42; my int $y = -1 * $x 08:40
then since the -1 is currently not an int, but rather an Int, it'll used the infix:<*>(Int, Int) candidate instead of infix:<*>(int, int)
the latter would be more efficient 08:41
timotimo oh, so it doesn't create a Want node?
moritz correct
it just creates a bare QAST::WVal node 08:42
timotimo so if the optimizer creates a WVal with an Int in it, it could then optionally/optimally create an int from that Int, and turn that WVal into a Want 08:43
does the Want contain a WVal for the Int still?
moritz yes 08:45
timotimo just looks by themself
oh. neat. so the WVal node can still be reused
can the same thing be done with strings? is there a Str vs str?
moritz it should trans form the QAST::WVal(Int) into a QAST::Want(QAst::WVal(Int), 'Ii', QAST::Ival(unboxed Int))
yes, Int, Str and Num
timotimo unboxing ints works how? i thought p6decont would do that, but it seems that op isn't available in Optimizer.pm, so maybe only in the Setting? 08:47
sorear nqp::unbox_{ins} mayb 08:48
moritz nqp::unbox_i($value)
timotimo: containers and boxing are mostly orthogonal
timotimo ah, i think i can implement this now :)
moritz ++timotimo
sorear if you have a (pseudocode) Scalar[Int[int]], p6decont gives you the Int, unbox_i gives you the int
timotimo ah, so the container thing is $i vs \i, the boxing is Int vs int, is that about accurate?
sorear rooooooughly 08:49
moritz the problem is that \i doesn't remove the container, it just preserve it
whereas unboxing always removes the box
timotimo ah, ok. 08:50
sorear Every value you can touch in perl 6 logically has a container
timotimo i'll have to fix my junction fail first, which is kind of a back-and-forth with not really knowing how nqp does things and taking 3 minutes to compile and getting distracted
sorear in nqp, you get to choose between bare values and containers, and can use p6decont to switch between them
(this is complicated by an optimization: when perl 6 sees a bare value, it imagines a read-only container. this lets us avoid allocating well over half of the containers that are logically needed) 08:51
moritz sorear: does a literal "logically" have a container? 08:52
sorear moritz: i would say so
moritz sorear: why?
sorear because you can do "foo".flip and the literal's container needs to be passed to the string method 08:53
timotimo ah, that's a good point 08:54
moritz a method call doesn't need a container
at least not in my world view 08:55
sorear your world view made no sense until I learned to understand it as an internalized optimization of mine
moritz one could say that "everything has a container, but they can often be optimized away" is roughly equivalent to "not everything has a container, but certain operations vivify them"
sorear yes, there are two possible ontologies there 08:56
and since they are observationally equivalent I am going to avoid any possible useless debate and sleep& 08:57

Strange...
moritz timotimo: spectesting your pull request 09:26
timotimo thank you :)
moritz: how much do you think will the optimization to turn WVal into Want in the optimizer give in performance? surely it could give a bit of a boost in long arithmetic expressions? 09:28
moritz timotimo: it'll only help where native types are used in tight loops
and there are operators with native types to dispatch to 09:29
jnthn Need to be careful about optimizations with natives also.
Two things that fit into an int being multiplied together or added, for example, can easily give something in big int range that must be an Int. 09:30
So with literals we have to be careful. We used to have bugs where 123456 * 123456 or so would come out negative 'cus it used int * int
masak good forenoon, #perl6 09:31
moritz good UGT morning, masak
jnthn The current state is that there should be at least one non-literal thing that is known to be an int, iirc. I'm pretty sure there's a comment somewhere in Optimizer.pm that explains it... :)

timotimo jnthn: github.com/rakudo/rakudo/blob/nom/...er.pm#L341 - i think i'm looking at the right spot here?
jnthn timotimo: The bit I was talking about is at github.com/rakudo/rakudo/blob/nom/...er.pm#L537 09:34
moritz timotimo: that was the part I was talking about, yes 09:35
timotimo i'm not exactly sure how those interplay
09:35 SamuraiJack left
moritz probably not much 09:35
09:36 berekuk left
timotimo right. but i will still have to check that the Int would actually fit into an int, yes? is there something in nqp already that does that? 09:36
moritz nqp::isbig iirc
nqp::isbig_I
jnthn I thought for literals we were already emitting a QAST::Want when the thing isn't big.
timotimo maybe for literals, but not for compile-time-evaluated things
moritz jnthn: yes, but not for the result of constant folding stuff
jnthn Oh! 09:37
OK, I see :)
timotimo we're talking about things like -5 and friends
jnthn Ah, which we ain't folding today?
moritz we are
timotimo it's folding all right
but not into a Want
moritz but the result is just a QAST::WVal
jnthn OK.
moritz not a QAST::Want(WVal, 'Ii', IVal)
jnthn *nod*
timotimo do you think it's worth investing in, jnthn? 09:38
jnthn Well, need to be careful, - can apply to many things.
So need to check the type of the exact value
timotimo: Yes, almost certainly
09:38 berekuk joined
timotimo yes, i was going to see if the return value is an Int and if it's not nqp::isbig_I, i'll create an int from it using nqp::unbox_I 09:38
jnthn timotimo: Just like all things optimizer, tread carefully; it's easy to get wronger as well as faster :)
timotimo unbox_i actually 09:39
jnthn timotimo: unbox_i, but yes.
timotimo: You could also check if it's a Num, fwiw.
Those can become a Want with an NVal too
timotimo sure, but i wanted to start small ;)
jnthn
.oO( a small task...involving nqp::isbig :P )
Have any of the folks here going to YAPC::EU made travel plans, ooc? 09:40
timotimo nqp::isa($return_val, Int), will that work? or will i have to use $!SETTING.symbol("Int")<value>?
jnthn nqp::istype
Oh, you'll need to look up Int
jnthn probably won't be able to stay and hack *after* YAPC::EU. 09:41
Before, however, is do-able. I'll certainly be at the Perl 6 hackathon, especially as it has my name of it :) 09:42
lizmat how much before?
fwiw,. we still haven't decided to either drive or fly
moritz isn't sure he'll make it to YAPC::EU at all
my wife just got a new aortic valve, and I won't be able to travel before her complete recovery 09:43
though if I'll make it, my employer will pay for it :-)
jnthn lizmat: Well, the hackathon is the Sunday before YAPC::EU. If there's a reason to, I can be about on the Saturday also, for example.
timotimo moritz: she's a cyborg! :D 09:44
jnthn moritz: Best wishes for the recovery.
lizmat best wishes, moritz!
moritz thanks jnthn, lizmat
timotimo best wishes from me, too :) 09:45
masak fourthed. 09:46
best wishes.
moritz timotimo: she is, but not because of the valve (that's "tissue engineered" from a human aortic valve, which means that the cells were removed to reduce the risk of rejection)
thanks timotimo, masak
timotimo oooh, that's even cooler 09:47
(but not cool in the way that it had to be done ... er) 09:48
moritz yes, it's the best option that exists today, and still experimental, and thus only done in one hospital in .de
(afaict)
timotimo wow. I hope it'll turn out good! both for your wife and everyone in the future to need a similar procedure 09:49

FROGGS[mobile] timotimo: what are you up to? 10:58
timotimo FROGGS[mobile]: when an inlined thing (like -5) returns an Int, the optimizer will now create a Want for it with an unboxed int in it as well as the WVal Int 10:59
next thing i'll do is the same thing with Num, and then with Str.
FROGGS[mobile] and that is good? 11:03
timotimo it will hopefully cause more operations in tight loops and such to run with native values instead of boxed values 11:04
tadzik the release is to be in 4 days, do we have a volunteer? 11:05
FROGGS[mobile] timotimo: so ideally this would only run for loops? 11:06

jnthn nwc10: It'll make multi-dispatches faster
moritz timotimo: BUILD is only called with named args, normally
jnthn nwc10: But since QAST compilation is LOADS of multi-dispatches (one per QAST node) it'll speed those up.
moritz (by bless, that is)
timotimo moritz: how come it only fails when my optimization is turned on and otherwise never noticed?!
oh, there's a custom BUILD there, too 11:35
it takes positional args
moritz huh.
timotimo: what code triggers it? 11:36
timotimo oh, i forgot to paste it
the code is just my %h = a => 1, b => -2, c => 5; or something similar
is it because i fail to move the SpecialArg thing outwards into the Want? 11:37
(i don't even know what that is)
moritz what about just my $ = (a => $b) ?
does that also fail?
arnsholt jnthn: Right. So NQP/JVM without cache was faster than Parrot with cache? That's promising =) 11:38
timotimo moritz: no, that works (when i set my $b = -5 for example)
moritz timotimo: seems that SpecialArg is related to named arguments
timotimo: you have to do something like
if $original_op.named { $new_op.named($original_op.named) } or something along the lines 11:39
arnsholt Unrelated, I sort of wish mrhdias would drop by here for help
timotimo ah, that's what that is for!
arnsholt Some of his bug reports aren't really bug reports
moritz because we represent named arguments not by pairs, but by a .named or .name or so property in the QAST nodes that represent the arguments

IMHO, the whole reblessing of cursors seems really hackish in the first place as it assumes the grammars inherit from each other 19:35

pmurias which shouldn't be true for Perl 5 either 19:36

gtodd moritz: just fiddling with the example github.com/moritz/svg-plot/blob/ma...rogress.pl to change out the CSV::Simple 20:26
timotimo if anyone finds out, i'd love to know why code using Num is faster than code using num. 20:27
gtodd timotimo: in the channel there's m: are: n: for evaling ... but I guess perlito is too much of a subset ?
geekosaur is num repeatedly unboxing and reboxing or something? 20:28
jnthn timotimo: The typical answer is because if you pass a num somewhere that needs an object and is untyped, then it has to box it to a Num. Do this a lot and you'll be reboxing it all the time.
geekosaur or more accurately the reverse
box->op->unbox->box->op->unbox...
20:28 DreamingInCode left
timotimo oh, well that's an answer. 20:28
could that be helped by adding more multi candidates for basic arithmetic for unboxed nums and friends? 20:29
