| ItchyPlant | Hi, just checking in to tell you that I managed to compile Rakudo on AIX (works both on 7.1, 7.2). :) | 08:42 | |
| I used "truss" to get more details about how that moar process dies during compilation and found "Err#12 ENOMEM" entries before it got segfault. | 08:44 | ||
| So I googled and found this in some pages but maybe this one tells it best: www-01.ibm.com/support/docview.wss...wg1PK94490 | |||
| So MoarVM's Makefile has this linking flag, and after that, all NQP, Rakudo compiles, all tests pass: | 08:45 | ||
| LDFLAGS = -Wl,-bmaxdata:0x80000000,-brtl -O3 -DNDEBUG -L"//opt/rakudo/lib" | |||

| samcv | ItchyPlant: so we need that compile flag on all AIX? | 09:35 | |
| just to have -bmaxdata:0x80000000 added? | |||
| ah looks like only 32 bit builds maybe? | 09:38 | ||
| anyway, i need to sleep now. will check on messages tomorrow :) good work | 09:41 | ||

| ItchyPlant | I was also experimenting what if I add block to 3rdparty/dyncall/dyncall/dyncall_macros.h about _AIX and not use libffi. In that case it passed the initial phase but failed here: | 09:53 | |
| dyncall_callvm_ppc32.c:57:2: error: #error Unsupported OS for ppc32 architecture. | |||
| So I reverted to the original solution, to just use "--has-libffi" | 09:57 | ||
| I wrote a step-by-step instruction about what had to be done to get it working... I'm still working on it. May I do it on Reddit or is there a better place for it? | 10:00 | ||
| lizmat | ItchyPlant: perhaps a PR for MoarVM documentation ? | 10:04 | |
| ItchyPlant | or rather on gist.github.com? | ||
| what is that? :) | |||
| lizmat | ItchyPlant: wherever you want to put it... | 10:05 | |
| ItchyPlant | OK | ||
| lizmat | someone will make sure it won't get lost by putting it in some repo where it will be kept | 10:06 | |
| nine | 11.878s! master is at 11.576s. Soooo close now | 10:17 | |
| ItchyPlant: that's great! Thanks for pushing this through! | 10:24 | ||
| ItchyPlant | Thank you all for all your help! It's a great community! :) | 10:25 | |

| Geth | MoarVM/master: 16 commits pushed by (Stefan Seifert)++ review: github.com/MoarVM/MoarVM/compare/0...db36d761c2 |
10:55 | |
| nine | ^^^ fixes, (read|write)(u?int|num) ops (jnthn++'s suggestion for the new API for handling binary buffers), serializetobuf and buffertocu ops and improved support for uints | 10:58 | |
| timotimo | will nqp get these ops right away, even before the new mast compiler? | 10:59 | |
| nine | That's the plan, yes | 11:00 | |
| timotimo | cool. | ||
| nine | If for no other reason than to make my rebases easier :) | 11:01 | |
| timotimo | right | ||
| i'll also be rebasing a thing or two | |||
| Geth | MoarVM: d8065362a3 | (Timo Paulssen)++ | src/spesh/optimize.c decont on nativeref shall become decont_* + box_* this way we should later be able to use the deconted value directly without boxing it first, and then more easily get rid of a native ref taking instruction. |
11:15 | |
| MoarVM: 950fb0e1f5 | (Timo Paulssen)++ | src/spesh/optimize.c set flags & known type on spesh slot unblocks optimizing the box_* into a fastbox, in the case of box_i it will even go through the int cache. |
|||
| timotimo | this, for example | ||
| nine | very nice :) | ||
| timotimo | maybe you can get the remaining ~0.4s by getting rid of the coerce_iu that follows the const_i64_16 :) :) | 11:17 | |
| lizmat | timotimo nine: time for a version bump ? | 11:18 | |
| nine | I wouldn't bet on it.... so far such clear optimizations have always yielded results that were hardly measurable. Only the sum of the optimizations has driven the time down | ||
| timotimo | right | 11:19 | |
| it was tongue-in-cheek anyway :) | |||
| it's just that sometimes really wasteful-seeming bytecode offends me :D | 11:20 | ||
| nine | Same here | ||
| timotimo | i mean, coerce_iu is surely extremely cheap | ||
| but using it on a constant is just silly | |||

| nine | Damn....rebasing my nqp branch brought me straight back into bootstrap hell. | 11:49 | |
| lizmat wonders why ItchyPlant just removed a new reddit post ? | 12:40 | ||
| ItchyPlant | I didn't post it under r/perl6 first, then I removed, but that didn't look disappeared, reposted... now it should be OK I guess. I'm new on reddit too. :) | 12:42 | |
| lizmat comments again :) | 12:43 | ||
| ItchyPlant | thanks | 12:46 | |
| nine | Finally....dug myself out again | 12:54 | |

| timotimo | \o/ | 13:59 | |
| nine: write_buf doesn't check for the slot type of the array before it uses the .u8 slot | 14:31 | ||
| that could go kind of wrong if it's used on a 16bit integer or 32bit integer vmarray | 14:32 | ||

| nine | Ok, this is becoming absurd. How on earth can it be that I get better times for stage mast if MVM_SPESH_LOG=spesh.log is set? | 15:31 | |
| The first two or three times I just thought it's random fluctuation. But it's...surprisingly consistent. | 15:32 | ||
| New record: 11.695s | |||

| timotimo | you can use MVM_SPESH_BLOCKING to get it to be more consistent | 16:33 | |
