◆ CompatibilityKind

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).

Definition at line 117 of file LangOptions.h.

◆ 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.

Possible float expression evaluation method choices.

Enumerator
FEM_Source Use the declared type for fp arithmetic.
FEM_Double Use the type double for fp arithmetic.
FEM_Extended Use extended type for fp arithmetic.
FEM_UnsetOnCommandLine Used only for FE option processing; this is only used to indicate that the user did not specify an explicit evaluation method on the command line and so the target should be queried for its default evaluation method instead.

◆ FPExceptionModeKind

Possible floating point exception behavior.

Enumerator
FPE_Ignore Assume that floating-point exceptions are masked.
