| timotimo | made some progress today for more detailed deopt | 00:54 | |
| MasterDuke | something for the profiler? | 01:06 | |
|

|
|||
| timotimo | aye | 01:07 | |
| the current profiler gives you "how often did which frames deopt_one or deopt_all" | |||
| i want the new one to display what expectations were violated, and by what. | |||

| timotimo | getting a strange segfault | 01:30 | |
| nine: if you could remove sp_* and prof_* and similar ops from the functions that write ops in MAST/Ops.nqp that'd be good | 02:09 | ||
| among other things because if you write any of these ops to your own code, the bytecode validator will yell at you | 02:11 | ||
| only spesh is allowed to build these | |||
| i wonder if perhaps a few of these functions should be re-used, i.e. whenever two opcodes have the exact same signature, which probably happens a bunch with the mathy ones | 02:13 | ||
| also, i wonder if $*MAST_FRAME is a major performance drain | 02:18 | ||
| rr replay being extremely slow right now :| | 02:24 | ||

|

| nine | timotimo: aye, $*MAST_FRAME cannot be good for performance. Alas adding a :$bytecode = $*MAST_FRAME.bytecode arg and passing it in in any place that already had access did not produce any measurable performance benefit :/ | 06:52 | |

nebuchad` is now known as nebuchadnezzar

| timotimo | OK! | 12:01 | |

| dogbert2_ | ok, so there seems to be one bug left in nine++ recent work | 14:13 | |
| nine | just one? :) | 14:36 | |

| dogbert2_ | :) one I 'know' | 14:54 | |

| timotimo | ugh, could this please finally crash properly under rr thanks | 15:07 | |
| nine | dogbert2_: timotimo may have been on the right track but in the wrong place. Look at lib/MAST/Nodes.nqp:853. Here's also a + but this time the operands are not guaranteed to be int32 | ||
| No idea though why this would fail only sometimes | 15:08 | ||

| dogbert2_ | nine: cool I'll try it out using timotimo's add_i suggestion | 15:19 | |
| nine, timotimo: I changed line 853 to '%!labels{nqp::iterkey_s($_)} := nqp::add_i(nqp::iterval($_), $insert_offset);' and now I get this instead ... | 15:33 | ||
| Duplicate label at 341678 at /home/dogbert/repos/rakudo/install/bin/../share/nqp/lib/MAST/Nodes.nqp:1088 (/home/dogbert/repos/rakudo/install/share/nqp/lib/MASTNodes.moarvm:add-label) | |||
| the number given for the duplicate label changes with each run | 15:34 | ||
| timotimo | what the heck ... | 15:35 | |
| nine | the number is just the objectid | 15:37 | |
| timotimo | so maybe it gets further after something borked earlier ... | 15:38 | |
| grrr | 15:41 | ||
| now i'm trying to debugprint something and gdb believes that MVMP6int doesn't exist | |||
