Member Data Documentation

ExpressionEvaluationContext clang::Sema::ExpressionEvaluationContextRecord::Context

The expression evaluation context.

Definition at line 798 of file Sema.h.

Referenced by isUnevaluated(), and clang::Sema::PopExpressionEvaluationContext().

SmallVector<CXXBindTemporaryExpr *, 8> clang::Sema::ExpressionEvaluationContextRecord::DelayedDecltypeBinds

If we are processing a decltype type, a set of temporary binding expressions for which we have deferred checking the destructor.

Definition at line 838 of file Sema.h.

SmallVector<CallExpr *, 8> clang::Sema::ExpressionEvaluationContextRecord::DelayedDecltypeCalls

If we are processing a decltype type, a set of call expressions for which we have deferred checking the completeness of the return type.

Definition at line 834 of file Sema.h.

bool clang::Sema::ExpressionEvaluationContextRecord::IsDecltype

Whether we are in a decltype expression.

Definition at line 804 of file Sema.h.

SmallVector<LambdaExpr *, 2> clang::Sema::ExpressionEvaluationContextRecord::Lambdas

The lambdas that are present within this context, if it is indeed an unevaluated context.

Definition at line 818 of file Sema.h.

Referenced by clang::Sema::PopExpressionEvaluationContext().

IntrusiveRefCntPtr<MangleNumberingContext> clang::Sema::ExpressionEvaluationContextRecord::MangleNumbering

The context information used to mangle lambda expressions and block literals within this context.

This mangling information is allocated lazily, since most contexts do not have lambda expressions or block literals.

Definition at line 830 of file Sema.h.

Decl* clang::Sema::ExpressionEvaluationContextRecord::ManglingContextDecl

The declaration that provides context for lambda expressions and block literals if the normal declaration context does not suffice, e.g., in a default function argument.

Definition at line 823 of file Sema.h.

unsigned clang::Sema::ExpressionEvaluationContextRecord::NumCleanupObjects

The number of active cleanup objects when we entered this expression evaluation context.

Definition at line 808 of file Sema.h.

Referenced by clang::Sema::PopExpressionEvaluationContext().

unsigned clang::Sema::ExpressionEvaluationContextRecord::NumTypos

The number of typos encountered during this expression evaluation context (i.e. the number of TypoExprs created).

Definition at line 812 of file Sema.h.

Referenced by clang::Sema::PopExpressionEvaluationContext().

bool clang::Sema::ExpressionEvaluationContextRecord::ParentNeedsCleanups

Whether the enclosing context needed a cleanup.

Definition at line 801 of file Sema.h.
