| MasterDuke | anybody have a suggestion for what could be happening with that segv uncovered by my new ternary warning in the optimizer? | 15:14 | |
| m: my $v = 3; my $sign = $v +> 31 ?? -1 !! 1; say $sign # this one | |||
| camelia | (signal SEGV) | ||
| MasterDuke | if i'm stopped at dispatch_o in the interpreter, is there a good way to see what all the arguments are? | 15:28 | |
| nine | MasterDuke: yes, look at callsite and args | 16:19 | |
| Or just MVM_dump_bytecode(tc) and look at the registers. That's even easier | 16:20 | ||
| MasterDuke | the problem with dumping the bytecode is that it's large (in this case especially so) and looking back and forth for that `->` to see where i am is annoying | 16:28 | |
| but maybe i'm in the right place randomly. i see 'lang-hllize', and then '$!descriptor', and then 'raku-rv-decont' | 16:30 | ||
| so maybe this is where the VMHash is getting upgraded into a P6opaque | |||
| oh, and a callsite doesn't know the argument values | 16:32 | ||
| nine | callsite knows how many and what kind of arguments to expect. args holds the register numbers of registers holding these arguments. tc->cur_frame->work holds the registers holding the arguments | 16:33 | |
| MasterDuke | might be nice to create some debug function to prettily print them | 16:35 | |
| interesting, i | 16:39 | ||
| 'm here github.com/rakudo/rakudo/blob/mast...de.pm6#L25 | |||
| well, i noticed that `method prec` is `is raw` in traits.pm6, but no change if i make the one in Code.pm6 `is raw` also | 16:44 | ||
