clippy crashes: couldn't extract literal #96721
Description
Code
clippy-driver crash.rs
macro_rules! foo {
() => {"bar.rs"};
}
#[path = foo!()] //~ ERROR malformed `path` attribute
mod abc;
fn main() {}CC @nnethercote you added this assert here: https://github.com/rust-lang/rust/pull/96546/files#diff-00567f9be31678eec46651e6157f0eaaa47d1f344eb61b8a63f87edfa7bf6b14R1589
looks like this triggers an ICE in clippy :(
