◆ ClangABI

enum class clang::LangOptionsBase::ClangABI

strong

Clang versions with different platform ABI conformance.

Enumerator
Ver3_8	Attempt to be ABI-compatible with code generated by Clang 3.8.x (SVN r257626). This causes <1 x long long> to be passed in an integer register instead of an SSE register on x64_64.
Ver4	Attempt to be ABI-compatible with code generated by Clang 4.0.x (SVN r291814). This causes move operations to be ignored when determining whether a class type can be passed or returned directly.
Ver6	Attempt to be ABI-compatible with code generated by Clang 6.0.x (SVN r321711). This causes determination of whether a type is standard-layout to ignore collisions between empty base classes and between base classes and member subobjects, which affects whether we reuse base class tail padding in some ABIs.
Ver7	Attempt to be ABI-compatible with code generated by Clang 7.0.x (SVN r338536). This causes alignof (C++) and _Alignof (C11) to be compatible with __alignof (i.e., return the preferred alignment) rather than returning the required alignment.
Ver9	Attempt to be ABI-compatible with code generated by Clang 9.0.x (SVN r351319). This causes vectors of __int128 to be passed in memory instead of passing in multiple scalar registers on x86_64 on Linux and NetBSD.
Ver11	Attempt to be ABI-compatible with code generated by Clang 11.0.x (git 2e10b7a39b93). This causes clang to pass unions with a 256-bit vector member on the stack instead of using registers, to not properly mangle substitutions for template names in some cases, and to mangle declaration template arguments without a cast to the parameter type even when that can lead to mangling collisions.
Ver12	Attempt to be ABI-compatible with code generated by Clang 12.0.x (git 8e464dd76bef). This causes clang to mangle lambdas within global-scope inline variables incorrectly.
Ver14	Attempt to be ABI-compatible with code generated by Clang 14.0.x. This causes clang to: mangle dependent nested names incorrectly. make trivial only those defaulted copy constructors with a parameter-type-list equivalent to the parameter-type-list of an implicit declaration.
Ver15	Attempt to be ABI-compatible with code generated by Clang 15.0.x. This causes clang to: Reverse the implementation for DR692, DR1395 and DR1432. pack non-POD members of packed structs. consider classes with defaulted special member functions non-pod.
Ver17	Attempt to be ABI-compatible with code generated by Clang 17.0.x. This causes clang to revert some fixes to its implementation of the Itanium name mangling scheme, with the consequence that overloaded function templates are mangled the same if they differ only by: constraints whether a non-type template parameter has a deduced type the parameter list of a template template parameter
Ver18	Attempt to be ABI-compatible with code generated by Clang 18.0.x. This causes clang to revert some fixes to the mangling of lambdas in the initializers of members of local classes.
Ver19	Attempt to be ABI-compatible with code generated by Clang 19.0.x. This causes clang to: Incorrectly mangle the 'base type' substitutions of the CXX construction vtable because it hasn't added 'type' as a substitution. Skip mangling enclosing class templates of member-like friend function templates.
Latest	Conform to the underlying platform's C and C++ ABIs as closely as we can.

◆ CompilingModuleKind

enum clang::LangOptionsBase::CompilingModuleKind

Enumerator
CMK_None	Not compiling a module interface at all.
CMK_ModuleMap	Compiling a module from a module map.
CMK_HeaderUnit	Compiling a module header unit.
CMK_ModuleInterface	Compiling a C++ modules interface unit.

Definition at line 99 of file LangOptions.h.

◆ 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.

Definition at line 441 of file LangOptions.h.

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

enum clang::LangOptionsBase::FPExceptionModeKind

Possible floating point exception behavior.

Enumerator
FPE_Ignore	Assume that floating-point exceptions are masked.
