@qyliss:fairydust.spaceAlyssa Rossmips doesn't seem like the best arch to start with given how little CPU power most MIPS machines have…12:08:07
@lotte:chir.rs@lotte:chir.rs yeah… 12:11:00
@lotte:chir.rs@lotte:chir.rs building a server system on riscv already takes a week lol 12:11:14

right but unsure what would be the best way here
12:20:38
@raitobezarius:matrix.orgraitobezariusI can see easily mrustc bootstrap, keeping old Rust versions around is meh but also second best I suppose, in all cases, it seems like a cross system is better for mips (?)12:21:09
@lotte:chir.rs@lotte:chir.rs although i haven't figured out a way to express "cross compile from x target to host target" 12:22:44
@lotte:chir.rs@lotte:chir.rs although i haven't figured out a way to express "cross compile from x target to host target" in nixpkgs 12:22:45
@lotte:chir.rs@lotte:chir.rs cross compilation maybe? 12:22:47

in nixpkgs or nixos?
12:26:21
@raitobezarius:matrix.orgraitobezariusyou can set up your system as a cross system in nixos by instantiating nixpkgs with crossSystem12:26:32

nixpkgs
12:27:00
@lotte:chir.rs@lotte:chir.rs i was trying to port the rustc bootstrap to aarch64 12:27:05
@raitobezarius:matrix.orgraitobezarius import <nixpkgs> { localSystem = "x target"; crossSystem = "host target"; } ? 12:27:19
@lotte:chir.rs@lotte:chir.rs mrustc isn't supported iirc and so i just wanted to cross compile a bootstrap compiler from x86 to aarch64 12:27:35

import <nixpkgs> { localSystem = "x target"; crossSystem = "host target"; } ?
no, inside of nixpkgs
12:27:46
@raitobezarius:matrix.orgraitobezariusah no inside of nixpkgs this is an open problem12:27:59
@lotte:chir.rs@lotte:chir.rs yeah 12:28:04
@raitobezarius:matrix.orgraitobezariusbut also I'm not sure this is something we want to do12:28:41
@qyliss:fairydust.spaceAlyssa Ross I don't think we should keep an old version around for it. I'm going to drop it, and if somebody wants Rust MIPS they should probably work with upstream to make that happen, given the reason it was dropped was LLVM codegen bugs. 12:28:48

Gotcha, seems reasonable

More precisely: if you need your bootstrap compilers to be cross compiled, but you want to have your next stage compilers to be natively compiled, you need to boot your own stages I think
