| timotimo figured out why lots and lots of smrt_numify and smrt_strify in nqp code weren't being optimized: | 02:44 | ||
| spesh couldn't figure out whether or not BOOTInt, BOOTNum, or BOOTStr could have .Str or .Num called on them | |||
| so i put in a cheat saying "no, there's no methods on these types" | |||
| and since there were plenty int-to-num-to-ints in there as well, i gave spesh an opt for that | 02:45 | ||
| int-to-num-to-int is safe, whereas num-to-int-to-num isn't, since num can have values larger than int can handle | 02:46 | ||
| and since it's nqp and almost all num usage is accidental, i don't think we need to emulate precision loss at higher numbers | |||
| would be interesting to see if it makes Perl6 code unhappy | 02:47 | ||
| could perhaps limit it to places where the HLL is nqp | 02:49 | ||
| many coerce_in (that is, int to num) remain because of deopt usage and such | 02:50 | ||
| but at least we don't have to intify the num any more | |||
| it does pass spec tests, so there might be a hole there perhaps | 02:58 | ||

| timotimo | oh, neat: gdb has $_regex and $_streq convenience functions available in breakpoint conditions | 13:48 | |

| brrt | \o | 14:49 | |
| timotimo++ | 14:50 | ||
| (for your late night research) | |||
| something that bothers me | 14:55 | ||
| MoarVM uses the name 'num' for floating points | |||
| lizmat | so does Perl 6 | ||
| brrt | everything else in the world uses 'float' | 14:57 | |
| which is, to be honest, far more accurate | |||
| lizmat was not involved in the naming | 15:01 | ||
| mornfall | yes i get regularly bitten by Num :( | 15:07 | |
| i expect that to be the root of the numerical type hierarchy | |||
| specifically i'm prone to write Num as a type constraint and then go wtf do you mean Int is not a Num /o\ | 15:09 | ||
| brrt | i wonder what is the top of the number chain | 15:10 | |
| jnthn | The Numeric role | 15:12 | |
| timotimo | oh, Real ly? | ||
| lucasb | timotimo :D | 15:14 | |
| timotimo | fwiw, javascript, which everybody loves, also calls floats "number" | 15:17 | |
| brrt | well, not everybody loves javascript, tbh | 15:18 | |
| lucasb | it's the only kind of Number JS has :) | ||
| brrt | also for lua | 15:19 | |
| and it works well for them, tbh | 15:20 | ||
| jnthn | I suspect "make all the basic numeric types 3 letters long" was a design consideration too :) | ||
| brrt | flt | 15:24 | |
| oh well :-) | |||
| timotimo | Cpx | ||
| brrt | heh, I can even understand that | ||
| timotimo | ctrl-printscrn-x? emacs users these days ... | ||

| .tell samcv - minilua can be compiled with just '-lm', and it'll work on any platform | 16:51 | ||
| yoleaux | brrt: I'll pass your message to samcv. | ||
| brrt | And that also fixes issue #999 (or at least I believe it ought to) | ||
| I'm beginning to think that having size parameters to operands was a bad idea | 16:55 | ||

| samcv | .tell brrt then we don't need to worry about libraries on the users computer changing? | 17:58 | |

| timotimo | Frame size: 33046 bytes (3318 from inlined frames) | 20:41 | |
| Specialization took 26781us (total 83586us) | |||
| JIT was successful and compilation took 56558us | |||
| Bytecode size: 141470 byte | |||
| oh | 20:42 | ||
| i have --optimize=0 | |||
| that will make a difference | |||
| the code is doing "save the $_ around this block" apparently | 20:43 | ||
