ICE: Span must not be empty and have no suggestion (E0308)

[Noratrieb]

⚠️ requires debug assertions ⚠️

Found with tree-crasher.

looks like a different root cause than #114251, but if you fix this also test that to be sure.

Code

fn a<F>(f: F) {
    loop {}
}

fn main() {
    a(
        for _ in 0.. {},
        {},
    );
}

Meta

rustc --version --verbose:

rustc 1.73.0-dev d56a73f75430fa8ae92e97beb8a0e21713289ba5

Error output

error: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

note: please attach the file at `/home/nils/projects/rust/tree-crasher/cases/rustc-ice-2023-07-30T15:15:05.737698896Z-3121992.txt` to your bug report

query stack during panic:
#0 [typeck] type-checking `main`
#1 [analysis] running analysis passes on this crate
end of query stack

There's more output about "no errors encountered even though delay_span_bug issued which doesn't really make sense as there were errors emitted, it just didn't fully complete emission.

Hello @Nilstrieb
I'm interested in taking this, but would you please give more context as to where to look for when fixing and how to test my modifications?

[Noratrieb]

The issue here is that the compiler wants to emit a suggestion in the error message, but the span (location) of the suggestion is empty/wrong. By looking at the backtrace, you can figure out where the error is emitted. Then you can look there to see why the span would be wrong.
See the rustc dev guide for help about building and running: https://rustc-dev-guide.rust-lang.org/building/how-to-build-and-run.html
You can also search the issue tracker for "Span must not be empty and have no suggestion" and look for issues that have been closed. The fixing PRs show how this issues was fixed in other places which may serve as inspiration, as this is an issue that keeps coming up in different places.

[meysam81]

@rustbot claim

[lukas-code]

This is actually (partially) fixed by #112500. ^{(Someone review that please?)}

But even though that PR makes the span no longer empty and technically correct, it could still use some improvements:

error[E0061]: this function takes 1 argument but 2 arguments were supplied
 --> src/main.rs:6:5
  |
6 |       a(
  |       ^
7 |           for _ in 0.. {},
  |  ________________________-
8 | |         {},
  | |         --
  | |_________||
  |           |help: remove the extra argument
  |           unexpected argument of type `()`
  |
note: function defined here
 --> src/main.rs:1:4
  |
1 | fn a<F>(f: F) {
  |    ^    ----

In particular, the "remove the extra argument" span should probably not include the previous , if that would make the span multi-line.

@meysam81 if you still want to work on this, the relevant code is here:

rust/compiler/rustc_hir_typeck/src/fn_ctxt/checks.rs

Lines 937 to 938 in 89acdae

	// Include previous comma
	span = prev.shrink_to_hi().to(span);

The SourceMap::is_multiline function may be useful and you can get a reference to the SourceMap with tcx.sess.source_map().
