| nine_ | I wonder for which problem would bitwise string ops be the best solution. | 09:01 | |
| Nicholas | "bitwise operations on byte buffers" I think | 09:03 | |
| I can't remember if I ever used them, or was just considering them as a solution to a problem, but using (equal length) "strings" of 0-255 gets you various efficient bitwise represtations, which was a potential solution for at least one problem | 09:05 | ||
| oh, that sentance needed better editing. | |||
| #moarvm, * good, *, *. ish. | 09:06 | ||
| nine_ | Yeah, that sounds more like byte buffers, for which I can totally see the need for bitwise operations | 09:11 | |
| Nicholas | but in perl 5 (and perl 4) all you have are hammers | 09:12 | |
| or something like that. Desert, floor polish, characters string and byte buffer. | 09:13 | ||

| Nicholas | ooh, fruitcake level shiny - lists.tetaneutral.net/pipermail/cf...00013.html | 10:47 | |
| I bet we can't build on them... | 10:48 | ||
| Geth | MoarVM: nwc10++ created pull request #1638: Add mimalloc submodule, and default to mimalloc where possible |

| dogbert11 | does anyone dare to merge github.com/MoarVM/MoarVM/pull/1636 ? | 12:07 | |

| Nicholas | Nope, can't build: | 12:17 | |
| 3rdparty/libatomicops/src/atomic_ops.h:430:5: error: #error Cannot implement AO_compare_and_swap_full on this architecture. | |||
| 430 | # error Cannot implement AO_compare_and_swap_full on this architecture. | |||
| | ^~~~~ | |||
| and oh my, updating submodules took a long time (and had to be edited to use ssh) | 12:18 | ||
| oh, mmm, I wonder if we could optionally use C11 atomics instead of libatomics API if we have the former... | 12:19 | ||
| nine_ | That would be nice | 12:48 | |
| Does MSVC support C11 atomics? | |||
| Nicholas | "Not enough" for the probe I created to pass. Turns out that mimalloc has #elif defined(_MSC_VER) | 12:51 | |
| and a special-snowflake implementation | 12:52 | ||

| [Coke] | good moarning. | 16:04 | |
| [Coke] wonders how hard it is to make this work in anything other than English | 16:05 | ||
| lizmat | goede moargen :-) | 16:07 | |
| Gute Moargen | |||
| Bon Joar (meh) | |||
| [Coke] | Danke! | 16:11 | |
| moarshi moarshi? . o O (Nope) | 16:12 | ||
| gfldex | In some parts of DE "Morgen" is acutally pronounced "Moargen". The "r" is almost lost tho. | 16:51 | |
| lizmat | yeah. "mogge" is also quite common in NL :-) which would be close to "moagge" :-) | 16:57 | |
| Geth | MoarVM: 9c2df858c3 | (Stefan Seifert)++ | 3 files Treat MVM_CALLSITE_ARG_(FLAT | NAMED) like FLAT_NAMED If both the FLAT and NAMED flags are set, this means exactly the same as the FLAT_NAMED flag, so we treat them the same. Later on we can free up the FLAT_NAMED flag. Doing this in two steps to avoid bootstrapping issues. |
16:59 | |
| MoarVM: b1069f7c6c | (Stefan Seifert)++ | 6 files Free up MVM_CALLSITE_ARG_FLAT_NAMED flag The flag is superseeded by the combination of MVM_CALLSITE_ARG_FLAT and MVM_CALLSITE_ARG_NAMED. Freeing it up, so we have a flag available for unsigned integers. |
|||
| lizmat feels a bump coming :-) | 17:00 | ||
| nine_ | lizmat: the NQP commit already contains a bump | 17:01 | |
| lizmat | aha! ok | ||
| nine_ | This is still preparatory work for the actual unsigned fixes | ||
| lizmat | yeah, got that :-) | ||
| nine_ | I'm glad that the branches are shrinking :) | 17:02 | |

| MasterDuke | Nicholas: many thanks for the mimalloc work. did you notice my concerns/questions about the telemeh-related changes? | 19:44 | |
| Nicholas | yes, sorry, hadn't got to a reply on that one yet | 19:46 | |
| MasterDuke | no worries, i just realized i made them on the old pr | ||
| hm. i did just compile CORE.c with telemetry logging and didn't get any errors... | 19:49 | ||
| which i honestly find surprising, i thought those particular changes were in fact incorrect. maybe not... | 19:51 | ||
| Nicholas++ | 19:58 | ||
| Nicholas | thank you for the sanity check | 20:01 | |
