Fields§

§function_coverage_map: RefCell<FxIndexMap<Instance<'tcx>, FunctionCoverageCollector<'tcx>>>

Coverage data for each instrumented function identified by DefId.

Implementations§

source§

impl<'ll, 'tcx> CrateCoverageContext<'ll, 'tcx>

source

pub fn new() -> Self

source

pub fn take_function_coverage_map( &self, ) -> FxIndexMap<Instance<'tcx>, FunctionCoverageCollector<'tcx>>

source

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.
