Struct rustc_codegen_llvm::coverageinfo::map_data::ZeroExpressions

source · 
struct ZeroExpressions(FxIndexSet<ExpressionId>);
Expand description

Set of expression IDs that are known to always evaluate to zero. Any mapping or expression operand that refers to these expressions can have that reference replaced with a constant zero value.
