| nine | And it works! | 08:02 | |
| Though it doesn't seem to have done anything for performance :( | |||
| At least it got rid of those extra QAST::SVals, but there are still 6636 more QAST::Ops than on master (61446 vs 54810). Of course compiling ops takes much more time than just SVals, so the hope for a performance gain is not lost at all. | 08:05 | ||
| Geth | MoarVM/nqp-mbc: 25d12cdec6 | (Stefan Seifert)++ | 2 files Seed the deserialization string heap for getting correct indexes Originally there were two pieces of code for collecting the string heap: the data serialization (nqp::serialize) and the MAST compiler. The strings collected during serialization were used as seed for the MAST compiler's string heap. MVM_serialization_serialize assumed that it was passed an empty string heap to fill. Since we now assemble bytecode (and the string heap) before serializing data, we have to flip this. Serialization's string heap is now seeded with the bytecode compiler's. |

| ItchyPlant | Hi All! May I ask for help about compiling MoarVM on an AIX 7.1 LPAR? :) | 11:35 | |
| nine | ItchyPlant: of course you may ask! I hope we'll also be able to help | 11:36 | |

| make: *** [Makefile:602: libmoar.so] Error 1 | |||
| I had to comment out the block about "endian.h" in out the the block in src/strings/siphash/csiphash.h, and also replaced the "STAT" word by something else in src/io/syncfile.c, because the compilation failed in the beginning. Now it compiles for some minutes and ends with the above. | 11:43 | ||
| nine | According to their docs, libuv would support AIX | 11:44 | |
| ItchyPlant | the details about how I'm progressed for now can be found also in Reddit: www.reddit.com/r/perl6/comments/9q..._6_on_aix/ | 11:45 | |
| nine | There are some notes however: github.com/libuv/libuv#aix-notes | 11:46 | |
| ItchyPlant | OK, let's see... | ||
| the mentioned bos.ahafs is installed already | 11:47 | ||
| and it stops at "linking libmoar.so" | 11:48 | ||
| I also tried with passing the "--static" parameter to Configure.pl and interestingly the compilation passes the libmoar.so, and stops at "linking moar". | 11:50 | ||
| But is it possible to get fully functional Perl 6 on AIX, right? There are notes about it on MoarVM's site at Releases, so I was really excited about it. It is still possible, right? | 12:06 | ||
| jnthn | Once you get past having MoarVM linking, then that should be most of the platform-specific stuff. I don't think any of the regular MoarVM developers have AIX access, so I'd not be surprised if some tweaks are needed. | 12:22 | |

|||
| timotimo | did you get both the branches i told you about? | 20:26 | |
| actually, parent_thread_id is totally uninteresting to the frontend at the moment | |||
| so you can just throw it out of the sql query in ProfilerWeb.pm6 | |||

| nine | I did so and it worked :) | 21:19 | |
| And it showed me exactly where the superfluous QAST::Ops were coming from - I misread some code and accidentally removed an optimization. Easily fixed :) | 21:20 | ||
| Current numbers for stage mast: 12.133s on nqp-mbc vs. 11.576s on master | |||
| timotimo | \o/ | 21:21 | |
| fantastic | |||
| how does gc usage compare? | |||
| probably just compare number of gc runs during that stage? | |||
| nine | 246 collections on nqp-mbc vs 267 on master | 21:27 | |
| niner.name/files/profile.sql.zst and niner.name/files/profile-master.sql.zst if you want to play with them | 21:28 | ||
| timotimo | how big is the difference in time spent in gc? | 21:32 | |
