| brrt | so, i've finally found all commits i want rebased on top of master | 07:10 | |
| nine | brrt: cool! That was probably the hardest part | 07:23 | |
| brrt | yeah, the next part is removing all accidentally added stuff from even-moar-jit | 07:27 | |
| samcv | yay | 07:29 | |
| nine | I wonder how many conflicts I'll get with the jit_nativecall branch after your merge | 07:31 | |
| brrt | not too many i hope, since you're not using the internal jit graph builder structure | ||
| fwiw, regarding the pain of building a jit graph by hand | |||
| i feel you :-) | |||
| the problems, or at least what i think is the problem, is that the 'legacy' jit has nonuniform objects, so you have to specify every damn thing by name | 07:32 | ||
| the expr JIT has a single 'type' of object (a node), and it's an integer, and it's stored in an array that can be modfiied by all the usual array methods | 07:33 | ||
| and… it's just much, much easier to do, even 'by hand' | |||
| the uniformity is a big part of why we can have templates, and tiling, and pattern matching, etc | 07:34 | ||
| and a universal tree traverser, etc | 07:37 | ||
| nine | I have no idea how long my code will survive in MoarVM, but at least I now have a very good idea how the lego JIT works (it's really that simple :)) and what the motivation for even-moar-jit was | 07:38 | |
| brrt | :-) | 07:42 | |
| samcv: i will publish my slides, yes, but i'ld like to add a transcript at the same time | |||
| or at least | |||
| some description that approximates the talk i gave with it | |||
| samcv | ok :) | 07:43 | |

| nine | brrt: is that all the changes? | 08:41 | |
| samcv | i need to start putting together my resume and looking for a job | 09:27 | |
| brrt | not yet | 09:43 | |
| nine | I think, I'm gonna do the unboxing of arguments in the generated native sub body, rather than in JITed code. That way spesh will be able to strip out unneeded unboxing (same as deconts). | 09:49 | |
| Also a somewhat funny part: at one point I will want to jit the nativecallinvokejit op itself to enable JITing those deconting and unboxing ops | 09:51 | ||

| MasterDuke | timotimo: do i just need your MoarVM branch for the binary heap analyzer change? or also a branch of the analyzer itself? | 12:38 | |

| Geth | MoarVM/jit-legacy-cleanup: 0ceb38a9ea | (Bart Wiegmans)++ | 6 files Replace explicit JIT function return frame check This greatly simplifies the JIT compiler driver and jump-out logic. MVM_frame_try_return is now called within the JIT-compiled code. |
15:15 | |
| MoarVM/jit-legacy-cleanup: 975bbb09b9 | (Bart Wiegmans)++ | 7 files Wrap dasm_State in MVMJitComiler structure This changes function signatures, but is not very exciting otherwise. It prevents spilling the dasm_State structure, and we can use it to collect all compiler state in a single object. |

| timotimo | i don't think anybody has used moarvm's tracing support in a loooooong time | 21:58 | |
| look it doesn't even get the op's name for you | |||
| MasterDuke | timotimo: gonna be afk for a bit, but do you have any thoughts on my INTERPOLATE questions in #perl6-dev? | 22:01 | |
| timotimo | why it gets called so often? | 22:03 | |
| i'd say "check out the --target=mast" or something, but i'm not sure | |||
