- * Header: remcom.c,v 1.34 91/03/09 12:29:49 glenne Exp $
- *
- * Module name: remcom.c $
- * Revision: 1.34 $
- * Date: 91/03/09 12:29:49 $
- * Contributor: Lake Stevens Instrument Division$
- *
- * Description: low level support for gdb debugger. $
- *
- * Considerations: only works on target hardware $
- *
- * Written by: Glenn Engel $
- * ModuleState: Experimental $
- *
- * NOTES: See Below $
- *
- * Modified for M32R by Michael Snyder, Cygnus Support.
- *
- * To enable debugger support, two things need to happen. 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 external function exceptionHandler() is
- * used to attach a specific handler to a specific M32R vector number.
- * It should use the same privilege level it runs at. It should
- * install it as an interrupt gate so that interrupts are masked
- * while the handler runs.
- *
- * 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
- * XAA..AA,LLLL: Write LLLL binary bytes at address OK or ENN
- * AA..AA
- *
- * 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
- *
- * ? What was the last sigval ? SNN (signal NN)
- *
- * All commands and responses are sent with a packet which includes a
- * checksum. A packet consists of
- *
- * $<packet info>#<checksum>.
- *
- * where
- * <packet info> :: <characters representing the command or response>
- * <checksum> :: <two hex digits computed as modulo 256 sum of <packetinfo>>
- *
- * When a packet is received, it is first acknowledged with either '+' or '-'.
- * '+' indicates a successful transfer. '-' indicates a failed transfer.
- *
- * Example:
- *
- * Host: Reply:
- * $m0,10#2a +$00010203040506070809101112131415#42
