 Tristan Ross | Yeah if you find a case where things just completely do not match then report it to the stdenv team. | 02:18:58 |
 @rosssmyth:matrix.org | And then Zig, at least last I checked, the triples were different from GCC and Clang. | 02:19:11 |
| Tristan Ross | Sort of | 02:19:50 |
| Tristan Ross | Most things should work. | 02:19:58 |
| @rosssmyth:matrix.org | I don't particularly care about most things though | 02:20:08 |
| Tristan Ross | But if you find an issue with Zig, lmk since I maintain it. | 02:20:13 |
| @rosssmyth:matrix.org | I've not tried using Zig as a C compiler in about two years because of the mess I had triying to use it before, | 02:20:39 |
| Tristan Ross | Yeah, though it's hard to know what the cases are without knowing what the cases are. So for now, we've stuck with a best effort thing. | 02:20:43 |

| Tristan Ross | Ok, you could try it now lol. A lot has changed in two years. | 02:21:05 |
| @rosssmyth:matrix.org | This is the arm-none-eabi | 02:21:08 |
| Tristan Ross | Yeah, I'll have to look into this when I have time. | 02:21:34 |
| Tristan Ross | Also, LLVM doesn't really use arch-os-abi. That actually might cause problems. | 02:22:03 |
| Tristan Ross | arch-vendor-os-abi is a better way of doing it. | 02:22:13 |
| @rosssmyth:matrix.org | yes | 02:22:19 |
| @rosssmyth:matrix.org | I am glad LLVM tries to be mostly sane | 02:22:29 |
| @rosssmyth:matrix.org | Looks like Zig forwards the triples to the Clang backend now days. Which is great. I remember the blog post Andrew Kelly wrote about it being a drop-in replacement for Clang for cross-compilation and it just wasn't true at all when the blog post was written because the triples were so different | 02:23:44 |
| Tristan Ross | Tbf, there's always going to be edge cases that aren't always going to be checked. | 02:24:34 |
| @rosssmyth:matrix.org | The edge case was...all of windows | 02:24:45 |
| Tristan Ross | Oh | 02:27:33 |
|  lazyLambda set a profile picture. | 03:24:14 |

 FliegendeWurst | Are there really platforms where the byte order is different for floats and integers? | 19:09:55 |
| FliegendeWurst | * Are there really platforms where the byte order is different for floats and integers?
I'm wondering, because I found this check: https://github.com/john30/ebusd/blob/25.1/CMakeLists.txt#L139-L165
But could not find any platform on godbolt that would trigger the other case. | 19:15:46 |
| @rosssmyth:matrix.org | For IEEE floats, no. | 19:38:59 |
| @rosssmyth:matrix.org | I think PDP had a funny thing where this was not true, but that was also before IEEE floats | 19:39:34 |
| @rosssmyth:matrix.org | * I think PDP had a funny thing where this was not always true, but that was also before IEEE floats | 19:39:50 |
| @rosssmyth:matrix.org | LLVM makes a lot of assumptions about the fp environment, so I would be surprised if llvm even supported such a thing. | 19:41:27 |
| @rosssmyth:matrix.org | * LLVM makes a lot of implicit assumptions about the fp environment, so I would be surprised if llvm even supported such a thing. | 19:43:28 |
