Public Attributes

ScopeKind Kind
 What kind of scope we are describing.
bool HasBranchProtectedScope
 Whether this function contains a VLA, , try, C++ initializer, or anything else that can't be jumped past.
bool HasBranchIntoScope
 Whether this function contains any switches or direct gotos.
bool HasIndirectGoto
 Whether this function contains any indirect gotos.
DiagnosticErrorTrap ErrorTrap
 Used to determine if errors occurred in this function or block.
SmallVector< SwitchStmt *, 8 > SwitchStack
SmallVector< ReturnStmt *, 4 > Returns
 The list of return statements that occur within the function or block, if there is any chance of applying the named return value optimization.
SmallVector< CompoundScopeInfo, 4 > CompoundScopes
 The stack of currently active compound stamement scopes in the function.
SmallVector
< PossiblyUnreachableDiag, 4 > 
PossiblyUnreachableDiags
 A list of PartialDiagnostics created but delayed within the current function scope. These diagnostics are vetted for reachability prior to being emitted.
