Member Function Documentation

const EnumType * EnumType::GetAsConstType ( ) const
virtual

Get a const version of this type. If it's already const, then the old Type pointer is returned.

Implements Type.

Definition at line 749 of file type.cpp.

References EnumType(), and isConst.

const EnumType * EnumType::GetAsNonConstType ( ) const
virtual

Get a non-const version of this type. If it's already not const, then the old Type pointer is returned.

Implements Type.

Definition at line 761 of file type.cpp.

References EnumType(), and isConst.

const EnumType * EnumType::GetAsSOAType ( int  width) const
virtual

Implements Type.

Definition at line 737 of file type.cpp.

References EnumType(), Type::GetSOAWidth(), Variability::SOA, and variability.

const EnumType * EnumType::GetAsUnboundVariabilityType ( ) const
virtual

Get an instance of the type with unbound variability.

Implements Type.

Definition at line 725 of file type.cpp.

References EnumType(), Type::HasUnboundVariability(), Variability::Unbound, and variability.

const EnumType * EnumType::GetAsUniformType ( ) const
virtual

Return a "uniform" instance of this type. If the type is already uniform, its "this" pointer will be returned.

Implements Type.

Definition at line 689 of file type.cpp.

References EnumType(), Type::IsUniformType(), Variability::Uniform, and variability.

const EnumType * EnumType::GetAsVaryingType ( ) const
virtual

Return a "varying" instance of this type. If the type is already varying, its "this" pointer will be returned.

Implements Type.

Definition at line 713 of file type.cpp.

References EnumType(), Type::IsVaryingType(), variability, and Variability::Varying.

const EnumType * EnumType::GetBaseType ( ) const
virtual

Returns the basic root type of the given type. For example, for an array or short-vector, this returns the element type. For a struct or atomic type, it returns itself.

Implements Type.

Definition at line 683 of file type.cpp.

std::string EnumType::GetCDeclaration ( const std::string &  name) const
virtual

Returns a string that is the declaration of the same type in C syntax.

Implements Type.

Definition at line 799 of file type.cpp.

References Assert, Module::errorCount, g, Target::getVectorWidth(), isConst, lShouldPrintName(), m, name, Variability::SOA, Variability::soaWidth, Globals::target, Variability::Unbound, variability, and Variability::Varying.

llvm::DIType EnumType::GetDIType ( llvm::DIDescriptor  scope) const
virtual

Returns the DIType (LLVM's debugging information structure), corresponding to this type.

Implements Type.

Definition at line 851 of file type.cpp.

References Assert, Module::diBuilder, enumerators, FATAL, SourcePos::first_line, g, SourcePos::GetDIFile(), Target::getVectorWidth(), lCreateDIArray(), m, name, pos, Variability::SOA, Variability::soaWidth, Globals::target, Variability::type, Variability::Uniform, variability, and Variability::Varying.

const Symbol * EnumType::GetEnumerator ( int  i) const

Returns the symbol for the given enumerator number.

Definition at line 943 of file type.cpp.

References enumerators.

int EnumType::GetEnumeratorCount ( ) const

Returns the total number of enuemrators in this enum type.

Definition at line 937 of file type.cpp.

References enumerators.

const std::string& EnumType::GetEnumName ( ) const
inline

Returns the name of the enum type. (e.g. struct Foo -> "Foo".)

Definition at line 400 of file type.h.

References name.

std::string EnumType::GetString ( ) const
virtual

Returns a text representation of the type (for example, for use in warning and error messages).

Implements Type.

Definition at line 773 of file type.cpp.

References Variability::GetString(), isConst, name, and variability.

Variability EnumType::GetVariability ( ) const
virtual

Returns the variability of the type.

Implements Type.

Definition at line 647 of file type.cpp.

References variability.

Referenced by lCheckTypeEquality().

bool EnumType::IsBoolType ( ) const
virtual

Returns true if the underlying type is boolean. In other words, this is true for individual bools and for short-vectors with underlying bool type, but not for arrays of bools.

Implements Type.

Definition at line 653 of file type.cpp.

bool EnumType::IsConstType ( ) const
virtual

Returns true if this type is 'const'-qualified.

Implements Type.

Definition at line 677 of file type.cpp.

References isConst.

bool EnumType::IsFloatType ( ) const
virtual

Returns true if the underlying type is float or double. In other words, this is true for individual floats/doubles and for short-vectors of them, but not for arrays of them.

Implements Type.

Definition at line 659 of file type.cpp.

bool EnumType::IsIntType ( ) const
virtual

Returns true if the underlying type is an integer type. In other words, this is true for individual integers and for short-vectors of integer types, but not for arrays of integer types.

Implements Type.

Definition at line 665 of file type.cpp.

bool EnumType::IsUnsignedType ( ) const
virtual

Returns true if the underlying type is unsigned. In other words, this is true for unsigned integers and short vectors of unsigned integer types.

Implements Type.

Definition at line 671 of file type.cpp.

llvm::Type * EnumType::LLVMType ( llvm::LLVMContext *  ctx) const
virtual
std::string EnumType::Mangle ( ) const
virtual

Returns a string that represents the mangled type (for use in mangling function symbol names for function overloading). The various Types implementations of this method should collectively ensure that all of them use mangling schemes that are guaranteed not to clash.

Implements Type.

Definition at line 786 of file type.cpp.

References Assert, isConst, Variability::MangleString(), name, Variability::Unbound, and variability.

const EnumType * EnumType::ResolveUnboundVariability ( Variability  v) const
virtual

Implements Type.

Definition at line 701 of file type.cpp.

References EnumType(), Variability::Unbound, and variability.

void EnumType::SetEnumerators ( const std::vector< Symbol * > &  enumerators)

Provides the enumerators defined in the enum definition.
