◆ HasConstantDestruction

unsigned 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.

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

◆ HasConstantInitialization

unsigned 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.

◆ HasICEInit

unsigned clang::EvaluatedStmt::HasICEInit

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

This affects whether the variable is usable in constant expressions.

◆ IsEvaluating

unsigned clang::EvaluatedStmt::IsEvaluating

Whether this statement is being evaluated.

◆ WasEvaluated

unsigned clang::EvaluatedStmt::WasEvaluated

Whether this statement was already evaluated.
