* 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 |

+\`configure' configures this package to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
+ --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
+ --localstatedir=DIR modifiable single-machine data [PREFIX/var]
+ --libdir=DIR object code libraries [EPREFIX/lib]

+ --oldincludedir=DIR C header files for non-gcc [/usr/include]
+ --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
