◆ CheckedForICEInit

bool clang::EvaluatedStmt::CheckedForICEInit

Definition at line 910 of file Decl.h.

Referenced by EvaluatedStmt(), and clang::VarDecl::hasICEInitializer().

◆ CheckedForSideEffects

bool clang::EvaluatedStmt::CheckedForSideEffects

Definition at line 913 of file Decl.h.

Referenced by EvaluatedStmt(), clang::VarDecl::hasInitWithSideEffects(), and clang::ASTDeclReader::ReadVarDeclInit().

◆ Evaluated

APValue clang::EvaluatedStmt::Evaluated

Definition at line 916 of file Decl.h.

Referenced by clang::VarDecl::getEvaluatedValue(), and clang::ASTDeclReader::ReadVarDeclInit().

◆ HasConstantDestruction

bool clang::EvaluatedStmt::HasConstantDestruction

Whether this variable is known to have constant destruction.

That is, whether running the destructor on the initial value is a side-effect (and doesn't inspect any state that might have changed during program execution). This is currently only computed if the destructor is non-trivial.

Definition at line 905 of file Decl.h.

Referenced by EvaluatedStmt(), clang::ASTNodeImporter::ImportInitializer(), clang::VarDecl::needsDestruction(), and clang::ASTDeclReader::ReadVarDeclInit().

◆ HasConstantInitialization

bool clang::EvaluatedStmt::HasConstantInitialization

Whether this variable is known to have constant initialization.

This is currently only computed in C++, for static / thread storage duration variables that might have constant initialization and for variables that are usable in constant expressions.

Definition at line 898 of file Decl.h.

Referenced by clang::VarDecl::checkForConstantInitialization(), EvaluatedStmt(), clang::VarDecl::hasConstantInitialization(), clang::ASTNodeImporter::ImportInitializer(), and clang::ASTDeclReader::ReadVarDeclInit().

◆ HasICEInit

bool clang::EvaluatedStmt::HasICEInit

In C++98, whether the initializer is an ICE.

This affects whether the variable is usable in constant expressions.

Definition at line 909 of file Decl.h.

Referenced by EvaluatedStmt(), and clang::VarDecl::hasICEInitializer().

◆ HasSideEffects

bool clang::EvaluatedStmt::HasSideEffects

Definition at line 912 of file Decl.h.

Referenced by EvaluatedStmt(), clang::VarDecl::hasInitWithSideEffects(), and clang::ASTDeclReader::ReadVarDeclInit().

◆ IsEvaluating

bool clang::EvaluatedStmt::IsEvaluating

Whether this statement is being evaluated.

Definition at line 892 of file Decl.h.

Referenced by EvaluatedStmt().

◆ Value

LazyDeclStmtPtr clang::EvaluatedStmt::Value

Definition at line 915 of file Decl.h.

Referenced by clang::VarDecl::ensureEvaluatedStmt(), and clang::ASTDeclReader::ReadVarDeclInit().

◆ WasEvaluated

bool clang::EvaluatedStmt::WasEvaluated

Whether this statement was already evaluated.

Definition at line 889 of file Decl.h.
