Constructor & Destructor Documentation

◆ SymbolUserMap()

SymbolUserMap::SymbolUserMap ( SymbolTableCollection symbolTable,
Operation symbolTableOp 
)

Build a user map for all of the symbols defined in regions nested under 'symbolTableOp'.

A reference to the provided symbol table collection is kept by the user map to ensure efficient lookups, thus the lifetime should extend beyond that of this map.
