One, a - * call to set_debug_traps() is necessary in order to allow any breakpoints - * or error conditions to be properly intercepted and reported to gdb. - * Two, a breakpoint needs to be generated to begin communication. This - * is most easily accomplished by a call to breakpoint(). Breakpoint() - * simulates a breakpoint by executing a trap #1. The breakpoint instruction - * is hardwired to trap #1 because not to do so is a compatibility problem-- - * there either should be a standard breakpoint instruction, or the protocol - * should be extended to provide some means to communicate which breakpoint - * instruction is in use (or have the stub insert the breakpoint). - * - * Some explanation is probably necessary to explain how exceptions are - * handled. When an exception is encountered the 68000 pushes the current - * program counter and status register onto the supervisor stack and then - * transfers execution to a location specified in it's vector table. - * The handlers for the exception vectors are hardwired to jmp to an address - * given by the relation: (exception - 256) * 6. These are decending - * addresses starting from -6, -12, -18, ... By allowing 6 bytes for - * each entry, a jsr, jmp, bsr, ... can be used to enter the exception - * handler. Using a jsr to handle an exception has an added benefit of - * allowing a single handler to service several exceptions and use the - * return address as the key differentiation. The vector number can be - * computed from the return address by [ exception = (addr + 1530) / 6 ]. - * The sole purpose of the routine _catchException is to compute the - * exception number and push it on the stack in place of the return address. - * The external function exceptionHandler() is - * used to attach a specific handler to a specific m68k exception. - * For 68020 machines, the ability to have a return address around just - * so the vector can be determined is not necessary because the '020 pushes an - * extra word onto the stack containing the vector offset - * - * Because gdb will sometimes write to the stack area to execute function - * calls, this program cannot rely on using the supervisor stack so it - * uses it's own stack area reserved in the int array remcomStack. - * - ************* - * - * The following gdb commands are supported: - * - * command function Return value - * - * g return the value of the CPU registers hex data or ENN - * G set the value of the CPU registers OK or ENN - * - * mAA..AA,LLLL Read LLLL bytes at address AA..AA hex data or ENN - * MAA..AA,LLLL: Write LLLL bytes at address AA.AA OK or ENN - * - * c Resume at current address SNN ( signal NN) - * cAA..AA Continue at address AA..AA SNN - * - * s Step one instruction SNN - * sAA..AA Step one instruction from AA..AA SNN - * - * k kill - * - * ?
