IRMaterializationUnit is a convenient base class for MaterializationUnits wrapping LLVM IR.

Represents materialization responsibility for all symbols in the given module. If symbols are overridden by other definitions, then their linkage is changed to available-externally.

Definition at line 32 of file Layer.h.

◆ SymbolNameToDefinitionMap

Create an IRMaterializationLayer.

Scans the module to build the SymbolFlags and SymbolToDefinition maps.

Definition at line 32 of file Layer.cpp.
