Detailed Description

Manages the connection among the GDB debugger and the stub which communicates with the processor; it is responsible of handling socket connection and of the coding and decoding of the messages. For more details on the internal workings of GDB look at http://sourceware.org/gdb/current/onlinedocs/gdb_33.html

Member Function Documentation

bool trap::GDBConnectionManager::checkInterrupt

(

)

Keeps waiting for a character on the channel with the GDB debugger

References error_code.

void trap::GDBConnectionManager::disconnect

(

)

Closes the connection with the GDB debugger.

void trap::GDBConnectionManager::initialize

(

unsigned int

port

)

Creates a socket connection waiting on the specified port; this will be later used to communicate with GDB

References THROW_ERROR.

Referenced by trap::GDBStub< unsigned int >::initialize().

trap::GDBRequest trap::GDBConnectionManager::processRequest

(

)

Waits for the sending of a packet from GDB; it then parses it and translates it into the correct request

Here is the call graph for this function:

void trap::GDBConnectionManager::sendInterrupt

(

)

Sends and interrupt message to the GDB debugger signaling that the execution of the program halted: this way the GDB debugger becomes responsive and it is possible to debug the program under test

References trap::GDBResponse::payload, trap::GDBResponse::S_rsp, SIGTRAP, and trap::GDBResponse::type.

void trap::GDBConnectionManager::sendResponse

(

GDBResponse &

response

)

Sends the response to the GDB debugger connected.
