Member Data Documentation

◆ Context

ExpressionEvaluationContext clang::Sema::ExpressionEvaluationContextRecord::Context

The expression evaluation context.

Definition at line 960 of file Sema.h.

◆ DelayedDecltypeBinds

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 1000 of file Sema.h.

◆ DelayedDecltypeCalls

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 996 of file Sema.h.

◆ ExprContext

enum clang::Sema::ExpressionEvaluationContextRecord::ExpressionKind clang::Sema::ExpressionEvaluationContextRecord::ExprContext

◆ IsDecltype

bool clang::Sema::ExpressionEvaluationContextRecord::IsDecltype

Whether we are in a decltype expression.

Definition at line 966 of file Sema.h.

◆ Lambdas

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 980 of file Sema.h.

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

◆ MangleNumbering

std::unique_ptr<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 992 of file Sema.h.

◆ ManglingContextDecl

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 985 of file Sema.h.

◆ NumCleanupObjects

unsigned clang::Sema::ExpressionEvaluationContextRecord::NumCleanupObjects

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

Definition at line 970 of file Sema.h.

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

◆ NumTypos

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 974 of file Sema.h.

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

◆ ParentCleanup

CleanupInfo clang::Sema::ExpressionEvaluationContextRecord::ParentCleanup

Whether the enclosing context needed a cleanup.

Definition at line 963 of file Sema.h.

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

◆ PossibleDerefs

llvm::SmallPtrSet<const Expr *, 8> clang::Sema::ExpressionEvaluationContextRecord::PossibleDerefs

Definition at line 1002 of file Sema.h.

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

◆ SavedMaybeODRUseExprs

llvm::SmallPtrSet<Expr*, 2> clang::Sema::ExpressionEvaluationContextRecord::SavedMaybeODRUseExprs

Definition at line 976 of file Sema.h.
