// Check that we emit some kind of diagnostic when MC/DC instrumentation sees
// code that exceeds the limit of 6 conditions per decision, and falls back
// to only instrumenting that code for branch coverage.
//
// See also `tests/coverage/mcdc/condition-limit.rs`, which tests the actual
// effect on instrumentation.
//
// (The limit is enforced in `compiler/rustc_mir_build/src/build/coverageinfo/mcdc.rs`.)
