ForwardingStatement

Statement whose symbol table contains foreach index variables in a local scope and forwards other members to the parent scope. This wraps a statement.

Members

Functions

flatten Statements* flatten(Scope* sc): ForwardingStatements are distributed over the flattened sequence of statements. This prevents flattening to be "blocked" by a ForwardingStatement and is necessary, for example, to support generating scope guards with `static foreach`:

Variables

statement Statement statement;: The wrapped statement.
sym ForwardingScopeDsymbol sym;: The symbol containing the static foreach variables.
