inlineprivate

Definition at line 121 of file remote_gdb.hh.

◆ data()

char* RiscvISA::RemoteGDB::RiscvGdbRegCache::data ( ) const

inlinevirtual

Return the pointer to the raw bytes buffer containing the register values.

Each byte of this buffer is literally encoded as two hex digits in the g or G RSP packet.

Implements BaseGdbRegCache.

Definition at line 128 of file remote_gdb.hh.

References r.

◆ getRegs()

void RemoteGDB::RiscvGdbRegCache::getRegs ( ThreadContext * )

virtual

Fill the raw buffer from the registers in the ThreadContext.

Implements BaseGdbRegCache.

◆ name()

const std::string RiscvISA::RemoteGDB::RiscvGdbRegCache::name ( ) const

inlinevirtual

Return the name to use in places like DPRINTF.

Having each concrete superclass redefine this member is useful in situations where the class of the regCache can change on the fly.

Implements BaseGdbRegCache.

Definition at line 134 of file remote_gdb.hh.

◆ setRegs()

void RemoteGDB::RiscvGdbRegCache::setRegs ( ThreadContext * ) const

virtual

Set the ThreadContext's registers from the values in the raw buffer.
