Expand description
Extra per-CGU context/state needed for coverage instrumentation.

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
.
