From bfadc3a9b9cb4bbfacddf6e73adff23a3557852b Mon Sep 17 00:00:00 2001 From: Zalathar Date: Tue, 30 Apr 2024 23:36:08 +1000 Subject: coverage: `CoverageIdsInfo::mcdc_bitmap_bytes` is never needed This code for recalculating `mcdc_bitmap_bytes` doesn't provide any benefit, because its result won't have changed from the value in `FunctionCoverageInfo` that was computed during the MIR instrumentation pass. --- compiler/rustc_codegen_llvm/src/coverageinfo/mod.rs | 7 +------ 1 file changed, 1 insertion(+), 6 deletions(-) (limited to 'compiler/rustc_codegen_llvm/src') diff --git a/compiler/rustc_codegen_llvm/src/coverageinfo/mod.rs b/compiler/rustc_codegen_llvm/src/coverageinfo/mod.rs index c51a7744a30..26ea95f0f0d 100644 --- a/compiler/rustc_codegen_llvm/src/coverageinfo/mod.rs +++ b/compiler/rustc_codegen_llvm/src/coverageinfo/mod.rs @@ -207,13 +207,8 @@ impl<'tcx> CoverageInfoBuilderMethods<'tcx> for Builder<'_, '_, 'tcx> { let cond_bitmap = coverage_context .try_get_mcdc_condition_bitmap(&instance, decision_depth) .expect("mcdc cond bitmap should have been allocated for merging into the global bitmap"); - let bitmap_bytes = bx.tcx().coverage_ids_info(instance.def).mcdc_bitmap_bytes; + let bitmap_bytes = function_coverage_info.mcdc_bitmap_bytes; assert!(bitmap_idx < bitmap_bytes, "bitmap index of the decision out of range"); - assert!( - bitmap_bytes <= function_coverage_info.mcdc_bitmap_bytes, - "bitmap length disagreement: query says {bitmap_bytes} but function info only has {}", - function_coverage_info.mcdc_bitmap_bytes - ); let fn_name = bx.get_pgo_func_name_var(instance); let hash = bx.const_u64(function_coverage_info.function_source_hash); -- cgit 1.4.1-3-g733a5
