From 078144fdfa7ae627d43cd919d660a71bef1e4658 Mon Sep 17 00:00:00 2001 From: Zalathar Date: Fri, 9 May 2025 20:57:17 +1000 Subject: coverage: Detect unused local file IDs to avoid an LLVM assertion This case can't actually happen yet (other than via a testing flag), because currently all of a function's spans must belong to the same file and expansion. But this will be an important edge case when adding expansion region support. --- compiler/rustc_interface/src/tests.rs | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'compiler/rustc_interface/src') diff --git a/compiler/rustc_interface/src/tests.rs b/compiler/rustc_interface/src/tests.rs index 0ceda220134..8bcd0453624 100644 --- a/compiler/rustc_interface/src/tests.rs +++ b/compiler/rustc_interface/src/tests.rs @@ -776,7 +776,8 @@ fn test_unstable_options_tracking_hash() { CoverageOptions { level: CoverageLevel::Mcdc, no_mir_spans: true, - discard_all_spans_in_codegen: true + discard_all_spans_in_codegen: true, + inject_unused_local_file: true, } ); tracked!(crate_attr, vec!["abc".to_string()]); -- cgit 1.4.1-3-g733a5
