Detailed Description
Structure used to store a statement, the constant value to which it was evaluated (if any), and whether or not the statement is an integral constant expression (if known).

◆ 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 896 of file Decl.h.

◆ 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.

◆ HasICEInit
| bool clang::EvaluatedStmt::HasICEInit |
In C++98, whether the initializer is an ICE.
This affects whether the variable is usable in constant expressions.

◆ WasEvaluated
| bool clang::EvaluatedStmt::WasEvaluated |
Whether this statement was already evaluated.
