 dramforever | or is it like, theoretical? | 06:18:26 |

NOTE: not always true! Some arm64 cpus don’t support arm32 mode
okay, not very confidence inspiring

| dramforever | chat should x64.canExecute x32 be true? it's not default enabled in linux | 06:23:29 |
| dramforever | i gave it false because it's false on my machine, currently at least, and now we have x86_64-unknown-linux-gnux32-gcc | 06:37:46 |
| dramforever | * i gave it false because it's false on my machine, currently at least, and now we are building x86_64-unknown-linux-gnux32-gcc | 06:42:25 |
| dramforever | hell yeah now we got business

| dramforever | let's see what the nixpkgs overlords have to say about this https://github.com/NixOS/nixpkgs/pull/398802 | 08:47:55 |
| dramforever | muslx32 hello also works | 09:14:30 |
| dramforever | my laptop working hard today | 09:14:41 |
| dramforever | sadly i can't get boost or python working | 11:07:27 |
| 16 Apr 2025 |
| dramforever | I found the boost problem. We package boost-build separately and use that instead because it's for pkgsBuildHost. I was wondering what on earth is going on... | 12:34:58 |
| dramforever | and libffi installed itself to libx32, which confused python | 12:56:12 |
| dramforever | we'll see | 12:56:16 |
| dramforever | we're at nix | 13:42:52 |

| dramforever | one sample per benchmark but the memory usage is fairly repeatable | 15:00:02 |

I got some good news from loongarch, apart from adding bootstrap tarball 😶🌫️ So just one 3C6000 borrowed from loongson community, but will probably be more to come | 04:58:03 |
