Detailed Description
This class represents a collection of SymbolTables.
This simplifies certain algorithms that run recursively on nested symbol tables. Symbol tables are constructed lazily to reduce the upfront cost of constructing unnecessary tables.

Lookup, or create, a symbol table for an operation.

◆ invalidateSymbolTable()
|
virtual |
Invalidate the cached symbol table for an operation.
This is important when doing IR modifications that erase and also create operations having the 'OpTrait::SymbolTable' trait. If a symbol table of an erased operation is not invalidated, a new operation sharing the same address would be associated with outdated, and wrong, information.

virtual |
Returns the operation registered with the given symbol name within the closest parent operation of, or including, 'from' with the 'OpTrait::SymbolTable' trait.
Returns nullptr if no valid symbol was found.
