Detailed Description

provides to architecture dependent registers as defined by gdb

gdb requires a predefined archtecture specific list of registers. Information about this list is provided by this class

Member Function Documentation

getInstructionPointer()

etiss::uint64 GDBCore::getInstructionPointer ( ETISS_CPU *  cpu )

virtual

allows to calculate the index of the instruction to be executed for breakpoint checks.

returns cpu->instructionPointer by default.

the OR1K architecture uses this to account for an invalid instruction pointer in case of a delay slot instruction

Reimplemented in RV64IMACFDGDBCore, and RV32IMACFDGDBCore.

Definition at line 74 of file GDBCore.cpp.

References ETISS_CPU::instructionPointer.

Referenced by etiss::plugin::gdb::Server::preInstructionCallback().

Here is the caller graph for this function:

isLittleEndian()

bool GDBCore::isLittleEndian ( )

virtual

returns true if the values are expected to be little endian

Reimplemented in RV64IMACFDGDBCore, and RV32IMACFDGDBCore.

Definition at line 70 of file GDBCore.cpp.

Referenced by etiss::plugin::gdb::Server::handlePacket().

Here is the caller graph for this function:

mappedRegisterCount()

unsigned GDBCore::mappedRegisterCount ( )

virtual

returns the number of registers in the gdb defined register list

Reimplemented in RV64IMACFDGDBCore, and RV32IMACFDGDBCore.

Definition at line 66 of file GDBCore.cpp.

mapRegister() [1/2]

unsigned GDBCore::mapRegister ( std::string  name )

virtual

returns the index of the given register name in the list of registers as defined by gdb.

max return INVALIDMAPPING if the passed name is not in the list

Reimplemented in RV64IMACFDGDBCore, and RV32IMACFDGDBCore.

Definition at line 62 of file GDBCore.cpp.

References INVALIDMAPPING.

mapRegister() [2/2]

std::string GDBCore::mapRegister ( unsigned  index )

virtual

the returned string identifies the register at the given index as defined by gdb.

the returned string must match the get/setRegisterXX() functions of etiss::CPUArch

Reimplemented in RV64IMACFDGDBCore, and RV32IMACFDGDBCore.
