โ—† ClangABI

Clang versions with different platform ABI conformance.

Definition at line 188 of file LangOptions.h.

โ—† 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 82 of file LangOptions.h.

โ—† CompilingModuleKind

Enumerator
CMK_None 

Not compiling a module interface at all.

CMK_ModuleMap 

Compiling a module from a module map.

Definition at line 116 of file LangOptions.h.

โ—† 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.

Definition at line 375 of file LangOptions.h.

โ—† CoreFoundationABI

Enumerator
Unspecified 

No interoperability ABI has been specified.

Standalone 

CoreFoundation does not have any language interoperability.

Swift5_0 

Interoperability with the Swift 5.0 runtime.

Swift4_2

Swift4_1 

Interoperability with the Swift 4.1 runtime.

FEM_Extended

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.
