| jnthn | nwc10: When I get a test fail in a ready-built NQP, I tend to assume the chances of NQP building aren't great :) | 14:29 | |
| (So didn't try it...) | |||
| nwc10 | ah right | 14:46 | |
| jnthn | It may be the JIT thing that I just didn't get to yet | 14:47 | |
| nwc10 | seesm to be. just passed all NQP tests after building/testing with MVM_SPESH_DISABLE=1 | 14:55 | |
| jnthn | What about MVM_JIT_DISABLE=1? | ||
| nwc10 | er, didn't find that first in shell history | 14:57 | |
| and also should I stop the rakudo build? | 14:58 | ||
| and also might be abducted by "Being socialable (TM)" | |||
| jnthn | Yeah, I need to get to the kitchen shortly too :) | 15:01 | |
| No worries, I don't think I'll have any problems reproducing the issue here :) | 15:02 | ||

| nwc10 | paste.scsys.co.uk/507024 -- valgrind output makes it look like a plain old NULL pointer dereference | 16:09 | |
| it's in MVM code, called from JIT generated code | 16:10 | ||
| which I think is pretty much what you thought | |||

| timotimo | hm | 18:46 | |
| so if i have a one-line patch for moarvm that makes nqp build and test on lazy-strings ... | 18:47 | ||
| should i push that? :) | |||
| dalek | arVM/lazy-strings: a501a41 | timotimo++ | src/jit/emit_x64.dasc: force sp_findmeth to decode strings in the CU makes nqp build&test and rakudo build. |
18:49 | |
| timotimo | we may want to actually use the return value of cu_string there, though | 18:50 | |
| but this makes things work already | |||
| hm. is Stage parse : 48.131 | 18:51 | ||
| kind of much faster than usually? | |||
| nope, not much faster | 18:56 | ||

| timotimo | i made a particle system for sdl2. it ends up taking a gigantic amount of IntLexRef and NumPosRef :( | 19:52 | |
| with the maximum particle count set to 1000 i get only about 30 fps average :| | 19:53 | ||
| hm, but there's also lots of Num objects being allocated by Bridge | |||
| and * and + | |||
| i can potentially fix those | |||

| timotimo | cool. i'm up to 51 median, 35 in the 5th percentile and 257 in the 95th percentile | 19:58 | |
| i guess the very high frame speeds come from having only few particles alive | 20:00 | ||

| timotimo | nwc10: what does? the whole thing with jit disabled? how about with my latest commit and jit & spesh re-enabled? | 21:11 | |
| nwc10 | oh, yes, it's your commit on what started as his branch | 21:12 | |
| oarVM/lazy-strings | |||
