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
12:07 reportable6 left
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

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.
MoarVM: b1069f7c6c | (Stefan Seifert)++ | 6 files

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
