 Yureka (she/her) | And you can decide to run any/most aarch64 hosts on 16k or 64k if you'd like to | 09:36:10 |
 K900 | Yeah aarch64 baseline includes support for bigger page sizes | 09:36:36 |
| K900 | It's just not particularly useful in most cases | 09:36:46 |
| K900 | Except Asahi machines because Apple IOMMU weirdness | 09:36:54 |
| Yureka (she/her) | Well depends on your workload | 09:36:58 |
| Yureka (she/her) | and tradeoffs | 09:37:14 |
 Vladimír Čunát | More precisely, POSIX chose that page size is not a compile-time constant. (I believe, after a bit of looking around) | 09:37:59 |
| Vladimír Čunát | * More precisely, POSIX chose that page size is not a compile-time constant. (I believe, after a bit of looking around) I think it would be too painful to diverge. | 09:38:31 |

| Yureka (she/her) | But yes it's definitely openblas 0.3.31 -> 0.3.32. Reverting that, I can also build scipy on my macbook again. I'll bisect openblas next. | 09:49:28 |

| Yureka (she/her) | Declare result as volatile to keep compilers from optimizing it out | 10:35:06 |
| Yureka (she/her) | Redacted or Malformed Event | 10:35:10 |

| Yureka (she/her) | https://github.com/OpenMathLib/OpenBLAS/issues/5708 | 10:36:10 |
| Yureka (she/her) | https://github.com/OpenMathLib/OpenBLAS/pull/5710 | 10:36:21 |
| Yureka (she/her) | https://github.com/NixOS/nixpkgs/pull/508576 | 10:42:20 |
| K900 | Oh yeah | 10:58:56 |
| K900 | @emily posted this before | 10:59:02 |
 emily | it was someone else. I just drive-by cringed at the terrifying workaround | 11:03:30 |
| Yureka (she/her) | Now only 17 failing tests in scipy | 11:04:12 |
| Yureka (she/her) | so there is something else borked | 11:04:20 |
| emily | I'm sceptical it's an actual miscompilation and not UB in OpenBLAS tbh | 11:04:31 |
| K900 | Should probably make it conditional on aarch64 | 11:04:33 |
| emily | not to say applying the upstream patch isn't the appropriate fix for now | 11:04:44 |
| emily | but very hard for me to imagine removing volatile turning correct code into a miscompilation esp. when it was added in a "fight the optimizer" folly. ah well | 11:05:57 |
| emily | libraries upstream of the whole universe and pervasive UB that actively breaks, name a more iconic duo | 11:06:55 |
 Randy Eckenrode | Alas, it appears the libiconv issue that Autoconf tests is not addressed. Still need to see on man-db. | 11:36:39 |
 Alyssa Ross | If upstream has applied it I don't think that makes sense (rebuilds aside) | 12:20:25 |
| K900 | Rebuilds yeah | 12:20:45 |
