| Geth | MoarVM/event_loop_started_status_without_mutex: f4e5a0a78f | (Timo Paulssen)++ | 6 files Use atomic instead of mutex for "is event loop started" The theory is that reading an atomic that only very rarely changes is cheaper than locking and unlocking a mutex for reading. Coverity Scan pointed out in CID 501093 that another thread could see instance->event_loop_thread become nonzero before the other field writes would be complete, thus causing a data race. ...

| Geth | MoarVM/region_allocator_always_align_eight: 2d27f825f1 | (Timo Paulssen)++ | src/core/regionalloc.c Always align region allocator allocations to multiples of 8 GCC 15.1 on OpenSuse Leap 16 mysteriously started using SIMD to optimize functions working with the succ, pred, or child arrays of BBs in spesh, causing a segfault when the allocation behaviour of the program caused one of these arrays to land on an address divisible by 4 but not by 8. Hopefully it's not a huge penalty to always align to 8 here. Shout-out to denizens of the Compiler Explorer Discord server for helping me diagnose what the compiler was up to. |

| MoarVM/fewer_unneeded_prof_allocated_calls: 059151e703 | (Timo Paulssen)++ | src/spesh/disp.c profiler: eliminate prof_allocated at end of disp program translation When a disp program gets compiled from a dispatch_o to spesh ops and the result of the program comes from a temporary, then it will result in a simple "set" op, which means we doesn't need a prof_allocated check after what used to be the dispatch_o op. |

| MoarVM/fewer_unneeded_prof_allocated_calls: 28105e18ee | (Timo Paulssen)++ | src/spesh/inline.c profiler: eliminate prof_allocated for getarg in inlined code When we rewrite a sp_getarg_o op to just be a set, then there is no reason to keep the prof_allocated check on the value |

| korvo | Redirect from #raku: Is it known whether Rakudo can be compiled statically with e.g. musl libc? I see that Alpine has a community port (pkgs.alpinelinux.org/package/edge/...86/rakudo) but that still uses DSOs. | 20:21 | |
| japhb | I think the answer to that may well be that it is *not* known. I think some attempt was made at this in the past, but I don't recall anybody claiming success. | 20:49 | |
| lizmat | [21:47:28] <patrickb> I seem to recall, that moar offers a build tool target to create a static library, but it never worked. I don't know what the blocker was though. | 20:52 | |
| Voldenet | moarvm uses libuv, so there might be some problems regarding that | 21:05 | |
