ICE `assertion failed: matches!(self.def_kind(ct.def), DefKind :: AnonConst)` if fn has generic param

[matthiaskrgr]

Code

#![feature(inline_const_pat)]

fn foo<const V: usize>() {
    match 0 {
        const { 1 << 5 } | _ => {}
    }
}

fn main() {}

interestingly the code compiles as soon as I remove <const V: usize> and just make it a boring foo() {...}

[oli-obk]

just needs to check for inline const along with anon consts in

rust/compiler/rustc_middle/src/mir/interpret/queries.rs

Line 98 in 3ed2a10

assert!(matches!(self.def_kind(ct.def), DefKind::AnonConst));

@rustbot claim

@oli-obk do you mean literally just adding | DefKind::InlineConst? Seems to fix the ICE on my end
