Detailed Description

A GDB target-description union type.

Each field is an alternative view of the same register data. Referenced field types must outlive the union.

◆ DumpToLog()

void RegisterTypeUnion::DumpToLog ( Log * log ) const

Definition at line 165 of file RegisterType.cpp.

References lldb_private::RegisterType::GetID(), LLDB_LOG, and m_fields.

◆ GetByteSize()

std::optional< uint64_t > RegisterTypeUnion::GetByteSize ( ) const

overridevirtual

Return this type's fixed size in bytes, if it has one.

No byte size means it depends on the target.

Reimplemented from lldb_private::RegisterType.

Definition at line 131 of file RegisterType.cpp.

References m_fields.

Referenced by IsByteSizeCompatible().

◆ GetFields()

const std::vector< Field > & lldb_private::RegisterTypeUnion::GetFields ( ) const

inline

Definition at line 154 of file RegisterType.h.

References m_fields.

◆ IsByteSizeCompatible()

bool RegisterTypeUnion::IsByteSizeCompatible ( uint64_t byte_size ) const

Definition at line 142 of file RegisterType.cpp.

References GetByteSize(), and m_fields.

◆ ToXMLElement()

void RegisterTypeUnion::ToXMLElement	(	Stream &	strm,
		const RegisterType *	user = nullptr ) const

overridevirtual

Output the register type as an XML element.

That is, "<foo ...>" until the closing </foo>, including any child types in between. For example the flags in a register flag set.

Implements lldb_private::RegisterType.
