◆ CompatibilityKind

enum class clang::LangOptionsBase::CompatibilityKind

strong

For ASTs produced with different option value, signifies their level of compatibility.

Enumerator
NotCompatible	Does affect the construction of the AST in a way that does prevent module interoperability.
Compatible	Does affect the construction of the AST in a way that doesn't prevent interoperability (that is, the value can be different between an explicit module and the user of that module).
Benign	Does not affect the construction of the AST in any way (that is, the value can be different between an implicit module and the user of that module).

◆ ComplexRangeKind

enum clang::LangOptionsBase::ComplexRangeKind

Controls the various implementations for complex multiplication and.

Enumerator
CX_Full	Implementation of complex division and multiplication using a call to runtime library functions(generally the case, but the BE might sometimes replace the library call if it knows enough about the potential range of the inputs). Overflow and non-finite values are handled by the library implementation. This is the default value.
CX_Improved	Implementation of complex division offering an improved handling for overflow in intermediate calculations with no special handling for NaN and infinite values.
CX_Promoted	Implementation of complex division using algebraic formulas at higher precision. Overflow is handled. Non-finite values are handled in some cases. If the target hardware does not have native support for a higher precision data type, an implementation for the complex operation will be used to provide improved guards against intermediate overflow, but overflow and underflow may still occur in some cases. NaN and infinite values are not handled.
CX_Basic	Implementation of complex division and multiplication using algebraic formulas at source precision. No special handling to avoid overflow. NaN and infinite values are not handled.
CX_None	No range rule is enabled.
