| nine | Looks like I've come across the first case where I have to change the actual compilation result. The result register kind of an nqp::if depends on the kind of the then and else branches. But I only know those after actually compiling them. So I may have to introduce intermediary registers. | 12:24 | |
| timotimo | nine: alternatively, use istrue_o and then if_i | 12:48 | |
| spesh does that anyway, but of course if_o results in smaller .moarvm files | 12:49 | ||

| timotimo | actually, i'm not entirely sure what problem you're actually edscribing | 13:14 | |
| i think i might have gotten it wrong | |||
| sorry about that | |||
| nine | The result type of nqp::if($cond, $then) is either the type of $cond if $cond and $then have the same type or just obj. The result type of nqp::if($cond, $then, $else) is either the type of $then if $then and $else have the same type or again just obj. In cases where $cond and $then or $then and $else have different types we also need to coerce the result to obj. | 13:18 | |
| My problem is that I only know the result type of $else after compiling it. So I don't know whether I need a coercer or not. | |||
| timotimo | oh! | 13:19 | |
| because the blocks return their result | |||
| i was thinking of the underlying bytecode %) | |||
| jnthn | Also I think there's a void handling where the return values don't matter | 13:28 | |
| nine | There is, yes. Which doesn't exactly make the code easier to digest ;) | 13:29 | |

ZzZombo joined,

|
|||
| nine | So I need an intermediary register for $then and coercion code which I emit after the $else and a goto in $else to jump over the $then coercer | 13:30 | |
| jnthn | Yeah, but the void context things have quite some nice performance impacts :) | 13:32 | |

| nine | Buuut....since I'm thinking of fixing up things afterwards already, would it be possible to fix up the register kind? That's really all that's dependent on the op's children. | 16:58 | |
| Of course that's not enough, since I also would need the coercing code | 17:02 | ||
| Geth | MoarVM: jstuder-gh++ created pull request #976: Exprjit Templates (09/20/18) |
17:35 | |
| MasterDuke | .ask brrt for function calls in templates, would there ever be anything in the arglist other than cargs? if not, would it makes to try and remove some of that boilerplate? | 17:49 | |
| yoleaux | MasterDuke: I'll pass your message to brrt. | ||

| Geth | MoarVM: e21836856f | (Samantha McVey)++ | 2 files Fix some printf format type specifiers Fix two in main.c that were causing warnings on clang. Fix some others that were not giving warnings, but should have been specified as unsigned, though they should never become big enough for that to actually matter. |

| samcv | what is this? JIT ERROR: Negative offset for dynamic label 8 | 21:59 | |
| it occured when i tried to call a method that doesn't exist for that type | 22:00 | ||
| No such method 'base' for invocant of type 'Str'. Did you mean any of these? | |||
| timotimo | well, that's pretty bad | 22:04 | |
| jnthn | Looks like a "the impossible happened" kind of error... | 22:05 | |
| Can check if it's expr-JIT sensitive with MVM_JIT_EXPR_DISABLE=1 | 22:06 | ||

| samcv | sec | 22:16 | |
| jnthn: yeah that gets rid of the error | |||
| code in question: | |||
| m: for <PRIMARY SECONDARY TERTIARY> { say 0x385.uniprop("MVM_COLLATION$_".base(16)) } | |||
| camelia | No such method 'base' for invocant of type 'Str'. Did you mean any of these? Hash asec hash take in block <unit> at <tmp> line 1 |
||
| samcv | working on updating us to unicode 11 | 22:17 | |
| jnthn | samcv++ | 22:20 | |
| timotimo | cool | 22:22 | |
| samcv | i'm glad there was nothing wrong with the collation, it just had a minor issue regenerating the file. because diving into that would be a huge pain | ||
| jnthn | Looks like some grapheme clustering changes, alas. | 22:24 | |
| samcv | i'm still amazed at how well it works. and there's only one function which looks a bit ugly | ||
| jnthn: yep | |||
| i have that fixed afaik already | |||
| jnthn | Though from the glimpse I took at it, it looked like it might just be a simpliciation. | ||
| timotimo | imgur.com/sW017ei - super crappy early look at my current task | ||
| jnthn | But maybe I'm just being an optimist :) | ||
| samcv | yeah i had to change some things | ||
| jnthn | NaN% :D | 22:25 | |
| samcv | it *did* make it simpler. my hours of time wasted! now i have to get rid of my code to workaround "should not break within emoji (you may have to modify these rules)" | ||
| timotimo | yeah, the columns will be replaced by allocation-related columns | ||
| samcv | something to that effect. i remember i thought the language used was humorous | ||
| Further customization of this rule may be necessary for best behavior of emoji zwj sequences [UTS51] | 22:26 | ||
| that's it | |||
| jnthn | hah, I loved that... | ||
| Might as well have said "Good luck with this!" | |||
| timotimo | can zwj become the new ffs ... | ||
| samcv | ffs? | ||
| timotimo | for f's sake | ||
| samcv | ah that's what i guessed but | ||
| wasn't 100% sure | 22:27 | ||
| timotimo | just make zwj an expletive | ||
| doesn't even matter what you invent for the expanded version | |||
| jnthn: you don't happen to have another blog post just about ready to release? :D | 22:33 | ||
| jnthn | No, 'fraid not :) | 22:37 | |
| Didn't decide what the next one will be about yet :) | |||
| timotimo | that's fair | 22:38 | |
