| ItchyPlant | Hello | 07:41 | |
| Some hours ago the MoarVM/NQP/Rakudo 2018.11 packages were released, which is great, and I'd like to try them too on AIX 7.2. | |||
| While 2018.10 could be compiled the same way as I succeded with 2018.09, now this new one fails at MoarVM part: | 07:42 | ||
| gist.github.com/ItchyPlant/114c0ca...17906ccafb | |||
| make[1]: *** No rule to make target 'atomic_ops/sysdeps/loadstore/acquire_release_volatile.template', needed by 'atomic_ops/sysdeps/loadstore/acquire_release_volatile.h'. Stop. | 07:43 | ||
| samcv | hey ItchyPlant | 07:51 | |
| side note. this wasn't able to get into the newest release github.com/MoarVM/MoarVM/pull/1004 | 07:52 | ||
| i did some work to try and get things compiling on aix. but i haven't tested it myself | |||
| Geth | MoarVM/master: 5 commits pushed by (Samantha McVey)++ | 07:53 | |
| samcv | gonna merge that now | ||
| ItchyPlant, though what you just mentioned seems unrelated | |||
| ItchyPlant | yes, this is something new | 07:55 | |
| samcv | hmm since libatomic wasn't updated i don't think | 07:56 | |
| ItchyPlant | I wrote all my experience with previous two versions here: www.reddit.com/r/perl6/comments/9s...9_on_aix7/ | ||
| samcv | yeah i read that :) | ||
| which prompted my changes which i just merged | |||
| can you show me your 3rdparty/libatomicops/src/Makefile | 07:58 | ||
| ItchyPlant | I'm glad it had some values. :) | ||
| sure, moment... | |||
| gist.github.com/ItchyPlant/9970f24...5b3c92eb3f | 08:00 | ||
| samcv | ItchyPlant, ok can you give me the output of `makefile -n` in the main MoarVM directory | 08:02 | |
| ItchyPlant | you mean 'make -n' I guess | 08:07 | |
| samcv | oh. yes :) | ||

|
|||
| samcv | oh. does `make -n` not do anything hmm | 08:08 | |
| let me check the aix make manual | |||
| well hat's weird. it printed some stuff. but also ran some commands | 08:11 | ||
| -n usually just prints command it would run and not run any of them | |||
| ItchyPlant, are you using a clean working tree? | 08:21 | ||
| or did you update moarvm using git | |||
| ItchyPlant | this is GNU make, not the IBM one but yes, --help for make says "-n, --just-print, --dry-run, --recon Don't actually run any recipe; just print them." | 08:22 | |
| yes, it is a clean, just extracted MoarVM-2018.11 package | |||
| samcv | ok | 08:23 | |
| Geth | MoarVM: ef9e65cac6 | (Samantha McVey)++ | build/Makefile.in Make sure libatomicops build file is removed with make realclean |
08:29 | |
| samcv | ItchyPlant, i'm not sure what's going on yet. and need to go to sleep soon | 08:30 | |
| could you make a moarvm issue which links to the outputs you have linked to me so far? | 08:31 | ||
| `make` output and `make -n` | |||
| oh also the generated Makefile in that folder | |||
| ItchyPlant | doing it... | 08:36 | |
| samcv | ok great | 08:37 | |
| ItchyPlant | thank you | ||
| good night :) | 08:38 | ||
| samcv | night! | ||

| Geth | MoarVM/pea: 255a21f93b | (Jonathan Worthington)++ | 3 files Record registers holding attrs to use in deopt And add dumping of them. This also means there's now a way in the spesh log to see which registers are holding attributes of a replaced object. |
10:47 | |
| jnthn | So the log has stuff like this now: | ||
| Materializations: | |||
| 0: Scalar from regs r29, r30 | |||
| Deopt point materialization mappings: | |||
| At 1 materialize 0 into r0 | |||
| At 1 materialize 0 into r2 | |||
| Well, OK, it does with my local patches that actually use this stuff :) | |||
| Now need to handle merge of this info during inline. | 10:49 | ||

| Geth | MoarVM/pea: 67bdab661d | (Jonathan Worthington)++ | src/spesh/deopt.c Don't confuse deopt offsets and indices We need to resolve offset to index (maybe in the future we'll just spit out the indices into the specialized bytecode and JIT output, though). Also place a materialization deopt call into global deopt. |

| Geth | MoarVM/pea: 7d7da3ca51 | (Jonathan Worthington)++ | src/spesh/deopt.c Materialize objects with object attrs during deopt |
14:07 | |
| jnthn | That actually seems to work :) | 14:12 | |
| (For a very small, contrived example :)) | 14:15 | ||
| Geth | MoarVM/pea: 26 commits pushed by (Jonathan Worthington)++, (Carl Masak)++ review: github.com/MoarVM/MoarVM/compare/7...537c58761a |
14:19 | |
| jnthn | And that's a rebase to make sure a bug I was seeing wasn't froma missing master change | ||
| It's quite explosive once actually enabled, alas. | 14:26 | ||

| jnthn | Seems at least part of it is the materialization table entries should also be hypothetical :) | 14:51 | |
| Or at least, we need to filter them before adding them for real. | |||
| Geth | MoarVM/pea: 76597e616f | (Jonathan Worthington)++ | src/spesh/deopt.c Note if deopt offset -> index resolution fails |
15:01 | |
| dogbert11 | jnthn: is your branch making stuff faster now or is there still more work to be done? | 15:12 | |
| Geth | MoarVM/pea: 5cc493f340 | (Jonathan Worthington)++ | src/spesh/pea.c Only add deopt in for allocations we replace Otherwise, we end up with incomplete and wrong information in the table, and could potentially end up deopting something completely bogus. |
15:24 | |
| jnthn | dogbert11: Hard to say in general, but it's certainly able to do optimizations - especially in combination with a Rakudo branch that does more aggressive lexical to local lowering - that eliminate some allocations, yes. | 15:25 | |
| dogbert11: Still lots to do in terms of making the optimization cover more cases, though before that would come making it correctly handle deopt, which is what I'm working on at the moment. | 15:26 | ||
| Once it can handle *that*, and the Rakudo branch that makes this more useful can be merged, then this is probably sensible to merge. | |||
| dogbert11 | cool, timotimo explained a bit yesterday about the 'partial' part in pea | 15:28 | |
| I guess your deopt logic is for that | 15:30 | ||
| Geth | MoarVM/pea: c69b455080 | (Jonathan Worthington)++ | src/spesh/pea.c Don't forget synthetic annotations |
15:57 | |
| MoarVM/pea: 6c422b08a7 | (Jonathan Worthington)++ | src/spesh/deopt.c Log deopt offset to index outcome |
|||
| jnthn | None of those solve it, alas. | 16:01 | |
| jnthn saves it for when he has more brane :) | |||
| Geth | MoarVM/pea: 69f352d71a | (Jonathan Worthington)++ | 2 files Switch on using the PEA deopt mechanism This, at present, causes quite a lot of breakage; something is still not quite right. |
16:03 | |
| jnthn | Also, going to be traveling for the next week, so pushed the busted bit just in case I get chance to look :) | ||
