 Tristan Ross | aleksana 🏳️⚧️ (force me to bed after 18:00 UTC): I saw loongarch64-unknown-linux-gnu now bootstraps. Do we support loongarch32-unknown-linux-gnu cross? | 17:24:30 |

| Tristan Ross | Fun | 17:25:12 |
| aleksana 🏳️⚧️ (force me to bed after 18:00 UTC) | And I'm in bed | 17:25:18 |
| Tristan Ross | Oh ok | 17:25:23 |
 Alyssa Ross | I don't think so | 17:25:25 |
| aleksana 🏳️⚧️ (force me to bed after 18:00 UTC) | I'll see if I can do anything tomorrow | 17:25:32 |
| Alyssa Ross | It's only very recent that anything supports that AIUI | 17:25:37 |
| Tristan Ross | Gotcha, I've opened https://github.com/NixOS/nixpkgs/pull/401821. | 17:39:07 |

 trofi | It's not idea, but it's intentional by nixpkgs. | 05:25:08 |
| trofi | It's embedded at https://github.com/NixOS/nixpkgs/blob/1ee8b713821882c66f5ecfde5c4e5874b1cb5e2f/pkgs/development/libraries/glibc/default.nix#L113 | 05:25:57 |
| trofi | Specifically glibc ever gets build by a handicap xgcc from early stages during the bootstrap:
$ nix-store --query --graph $(nix-instantiate -A glibc) |& grep -P -- '.*gcc.*->.*glibc'
"qn5vjz1dxigfax34am4k4zxcx1y3q3v0-bootstrap-stage2-gcc-wrapper-14.2.1.20250322.drv" -> "q9rikjkwdf1qnlypwxr78jfmh9q99k1g-glibc-2.40-66.drv" [color = "blue"];

| aleksana 🏳️⚧️ (force me to bed after 18:00 UTC) | There isn't any consumer for these micro-architectures https://github.com/NixOS/nixpkgs/blob/master/lib/systems/architectures.nix | 12:08:25 |
| aleksana 🏳️⚧️ (force me to bed after 18:00 UTC) | How are they supposed to be applied to a package or stdenv? | 12:08:54 |
| aleksana 🏳️⚧️ (force me to bed after 18:00 UTC) | I'm hitting a similar situation for loongarch64, where I'm advised to raise march level by default, but I still want to preserve the possibility to build with lower march level. See doc https://github.com/loongson/la-softdev-convention/blob/master/la-softdev-convention.adoc#10-operating-system-package-build-requirements | 12:10:29 |

| aleksana 🏳️⚧️ (force me to bed after 18:00 UTC) | Okay, so any usage of lib.systems.architectures.features? | 14:56:46 |

Okay, so any usage of lib.systems.architectures.features? Not that I'm aware of but I'll have to look at what it is first. | 15:00:14 |
| aleksana 🏳️⚧️ (force me to bed after 18:00 UTC) | It doesn't look like an exhausive list of either gcc features or /proc/cpuinfo | 15:03:42 |
| aleksana 🏳️⚧️ (force me to bed after 18:00 UTC) | Also what is the difference between lib.systems.platforms and lib.systems.examples? Why is armv7a-android in platforms while aarch64-android in examples? | 15:59:36 |
