ICE: not implemented: f16_f128 #122587
Description
Activity
that's expected, the float types are still being added and will panic, please don't fuzz them yet.
the file is from the rustc repo, have you not read the ticket?
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.mvce:
const b: f16 = 0.0f16; pub fn main() { let b = 0.0f16; }

@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)Cranelift still has problems, but I dunno if you want to tackle this 😅
thread 'rustc' panicked at src/common.rs:67:29: 'not implemented: f16_f128''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.
Going to close this since the obvious codepaths have been taken care of, anything less obvious is probably better off in its own issue.
