Member Data Documentation

◆ Context

ExpressionEvaluationContext clang::Sema::ExpressionEvaluationContextRecord::Context

The expression evaluation context.

Definition at line 1136 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 1169 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 1165 of file Sema.h.

◆ ExprContext

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

◆ ImmediateInvocationCandidates

llvm::SmallVector<ImmediateInvocationCandidate, 4> clang::Sema::ExpressionEvaluationContextRecord::ImmediateInvocationCandidates

Set of candidates for starting an immediate invocation.

Definition at line 1179 of file Sema.h.

Referenced by HandleImmediateInvocations().

◆ IsDecltype

bool clang::Sema::ExpressionEvaluationContextRecord::IsDecltype

Whether we are in a decltype expression.

Definition at line 1142 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 1156 of file Sema.h.

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

◆ 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 1161 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 1146 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 1150 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 1139 of file Sema.h.

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

◆ PossibleDerefs

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

Definition at line 1171 of file Sema.h.

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

◆ ReferenceToConsteval

llvm::SmallPtrSet<DeclRefExpr *, 4> clang::Sema::ExpressionEvaluationContextRecord::ReferenceToConsteval

Set of DeclRefExprs referencing a consteval function when used in a context not already known to be immediately invoked.

Definition at line 1183 of file Sema.h.

Referenced by HandleImmediateInvocations().

◆ SavedMaybeODRUseExprs

MaybeODRUseExprSet clang::Sema::ExpressionEvaluationContextRecord::SavedMaybeODRUseExprs

Definition at line 1152 of file Sema.h.

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

◆ VolatileAssignmentLHSs

SmallVector<Expr*, 2> clang::Sema::ExpressionEvaluationContextRecord::VolatileAssignmentLHSs

Expressions appearing as the LHS of a volatile assignment in this context.

We produce a warning for these when popping the context if they are not discarded-value expressions nor unevaluated operands.
