struct RiscvISA::RemoteGDB::RiscvGdbRegCache::@20 RiscvISA::RemoteGDB::RiscvGdbRegCache::__attribute__ ( (__packed__)  )

private

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 BaseRemoteGDB::BaseGdbRegCache.

Definition at line 73 of file remote_gdb.hh.

References RiscvISA::r.

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

virtual

Fill the raw buffer from the registers in the ThreadContext.

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 BaseRemoteGDB::BaseGdbRegCache.

Definition at line 79 of file remote_gdb.hh.

References BaseRemoteGDB::BaseGdbRegCache::gdb, and BaseRemoteGDB::name().

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

virtual

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

size_t RiscvISA::RemoteGDB::RiscvGdbRegCache::size ( ) const

inlinevirtual

Return the size of the raw buffer, in bytes (i.e., half of the number of digits in the g/G packet).

Implements BaseRemoteGDB::BaseGdbRegCache.
