#![allow(unused_braces)]

// FIXME(bootstrap): This isn't a known bug, we just don't want to write any error annotations.
// this is hard because macro expansion errors have their span be inside the *definition* of the
// macro rather than the line *invoking* it. This means we would wind up with hundreds of error
// annotations on the macro definitions below rather than on any of the actual lines
// that act as a "test".
//
// It's also made more complicated by the fact that compiletest generates "extra" expected
// notes to give an assertable macro backtrace as otherwise there would *nothing* to annotate
// on the actual test lines. All of these extra notes result in needing to write hundreds of
// unnecessary notes on almost every line in this file.
//
// Even though this is marked `known-bug` it should still fail if this test starts ICEing which
// is "enough" in this case.

// Test that we correctly create definitions for anon consts even when
// the trivial-ness of the expression is obscured by macro expansions.
//
// Acts as a regression test for: #131915 130321 128016
