Janus | the fact that e.g. recordDotSyntax is always on and can't be turned off means that lots of code isn't compatible | 04:37:06 |
Janus | I've just removed NonDecresingSyntax use from happy to make it compatible | 04:37:25 |

it sounds like [going via old GHC] is not the plan
I'd rather not because of old LLVM and worse support for old arches, but if nothing else works I will. | 04:38:47 |

Janus | In reply to @emilazy:matrix.org it doesn't seem out of the question for augustss to just go and implement every relevant GHC extension :) also , I think augustss might have some strong views on some of these newer extensions. I don't feel like digging now but it might be in the talks he did | 04:39:08 |
Janus | are you coming to zurihac ? augustss is going to be there this year | 04:39:37 |

I'd rather not because of old LLVM and worse support for exotic arches, but if nothing else works I will. some arches were better supported back then .. GHC was started on Sparc ;) | 04:41:25 |
Alex | Some of them have rotted? Unfortunate, but I'm most concerned about RISC-V support, which old versions definitely lack. | 04:42:48 |
Tristan Ross | RISC-V definitely isn't anything to worry about lol. I've struggled to get things working, even with a good setup. | 04:43:50 |
Janus | In reply to @alex:tunstall.xyz Some of them have rotted? Unfortunate, but I'm most concerned about RISC-V support, which old versions definitely lack. Sparc rotted everywhere since they were uncompetitive with Intel . basically sun gave up on having their own arch. | 04:45:04 |
Janus | anyway, exotic archs is ideally an orthogonal effort . bootstrapping is hard enough already , not sure why you want to make it even harder by considering exotics | 04:46:45 |
Janus | if you have it working on 32 bit Intel you can always try cross compiling from any point in the compiler chain | 04:47:17 |
Janus | I would even consider running on modern systems an unnecessary way to make things harder | 04:48:24 |
Janus | for example, nhc crashes on 64 bit IIRC | 04:48:40 |
Janus | it's likely that old GHC runtime systems have similar issues . even though Linux promises 100% backwards compat, they did Change the syscall Interface | 04:49:31 |
Janus | like, I think ghcup fails to install GHC 7.10 on modern ubuntus ? another example of broken compat | 04:51:46 |
Alex | Yeah I know about nhc98's reliance on 32-bit. I have much higher hopes that MicroHs doesn't have such silly issues and, even if it did, it would be much easier to patch & upstream.
Some exotics is better than none; right now, we only have what upstream has bindists for. | 04:54:46 |
emily | well, except that Nixpkgs barely supports i686-linux at this point | 04:54:54 |
