Expand description
A context object for maintaining all state needed by the coverageinfo module.
Fields§
§function_coverage_map: RefCell<FxIndexMap<Instance<'tcx>, FunctionCoverageCollector<'tcx>>>
Coverage data for each instrumented function identified by DefId.
pgo_func_name_var_map: RefCell<FxHashMap<Instance<'tcx>, &'ll Value>>

) -> Option<&'ll Value>
fn try_get_mcdc_condition_bitmap( &self, instance: &Instance<'tcx>, decision_depth: u16, ) -> Option<&'ll Value>
LLVM use a temp value to record evaluated mcdc test vector of each decision, which is called condition bitmap.
In order to handle nested decisions, several condition bitmaps can be
allocated for a function body.
These values are named mcdc.addr.{i}
and are a 32-bit integers.
They respectively hold the condition bitmaps for decisions with a depth of i
.
