note: we would appreciate a bug report: https://github.com/rust-lang/rust-clippy/issues/new?template=ice.yml

note: please attach the file at `/home/gh-matthiaskrgr/vcs/github/rust_icemaker/rustc-ice-2024-03-16T09_08_43-265551.txt` to your bug report

The text was updated successfully, but these errors were encountered:

Noratrieb · 2024-03-16T09:16:28Z

that's expected, the float types are still being added and will panic, please don't fuzz them yet.

matthiaskrgr · 2024-03-16T09:35:46Z

the file is from the rustc repo, have you not read the ticket?

Noratrieb · 2024-03-16T09:41:57Z

Yes, the file tests that float name resolution works. A lot of areas, including clippy, are stubbed out with todo!() for now, so it's expected that clippy would die on such a file.

With the current way feature gating works, it's inevitable that it will lead to these kinds of problems. it might make sense to make feature gating fatal. either way I don't think this has a particularly high priority

apiraino · 2024-03-20T21:18:40Z

WG-prioritization assigning priority (Zulip discussion).

@rustbot label -I-prioritize +P-low

tgross35 · 2024-03-26T04:37:52Z

Yeah, I will be updating Clippy after I have some slightly improved libs support

@rustbot claim

tgross35 · 2024-03-26T04:38:08Z

Feel free to ping / assign me on any f16/f128 issues btw

Noratrieb · 2024-03-26T06:21:30Z

As an org member, I think you should be able to configure notifications for this repo so that you get notified whenever someone applies the F label.

tgross35 · 2024-03-26T06:29:51Z

Thanks, I had no clue that was a thing. Awesome.

(looks like you don't even need to be an org member to do this, just tried with something else)

It turns out there is a bit of a circular dependency - I cannot add anything to `core` because Clippy fails, and I can't actually add correct Clippy implementations without new implementations from `core`. Change some of the Clippy stubs from `unimplemented!` to success values and leave a FIXME in their place to mitigate this. Fixes <rust-lang#122587>

Hmm which line does it say it's panicking at? I am running with

That seems to work fine, not sure if there is a less clunky way to build and run clippy in-tree

…xyas Change `f16` and `f128` clippy stubs to be nonpanicking It turns out there is a bit of a circular dependency - I cannot add anything to `core` because Clippy fails, and I can't actually add correct Clippy implementations without new implementations from `core`. Change some of the Clippy stubs from `unimplemented!` to success values and leave a FIXME in their place to mitigate this. Fixes <rust-lang/rust#122587>

also fun fact: I found this code from 2014 which also panics again 😅

#![feature(quad_precision_float)]

static x: f128 = 1.0 + 2.0;

fn foo(a: f128) -> f128 { a }

pub fn main() {
    let y = x;
    foo(y);
}

I don't even think the old gate is needed for that (though funny that it exists). Unfortunately anything that can get const evaled will ICE until I can update that portion of the code, which can't happen until we have arithmetic working on all platforms, which won't work until I have compiler_builtins updated, which is a huge pain that I am currently working on... Dependencies 😆

tgross35 · 2024-06-19T03:59:58Z

@matthiaskrgr is there anything in tree testing this? #126636 should fix it but I don't see anything to update if it exists

tgross35 · 2024-06-21T03:00:48Z

The above checks fine since #126636 but I forgot the Fixes tag, could somebody close this?

Ah, that last ICE point should be covered by #123088. Is there something edition-specific?

does not seem to be edition dependant.

Fixes <rust-lang#122587>

tgross35 · 2024-06-26T00:01:46Z

@matthiaskrgr no more 🧊 in the latest nightly, a previously-panicking test was included in https://github.com/rust-lang/rust/blob/fda509e817abeeecb5b76bc1de844f355675c81e/tests/ui/consts/const_in_pattern/f16-f128-const-reassign.rs.

Could we close this broad-ish issue and just open new ones if new ICEs pop up? (There are some unimplemented!s floating around in const casting and math still, but hopefully gone in the next few weeks)

matthiaskrgr · 2024-06-26T06:02:13Z

Cranelift still has problems, but I dunno if you want to tackle this 😅

tgross35 · 2024-06-26T06:09:45Z

Yeah, lower priority :) rust-lang/rustc_codegen_cranelift#1461 is tracking that one. cg_gcc has the issue too but that one is fixed in the rustc_codegen_gcc repo, just waiting on a sync.

tgross35 · 2024-07-19T06:55:21Z

Going to close this since the obvious codepaths have been taken care of, anything less obvious is probably better off in its own issue.
