Series 700/800
The following options are also supported:
-snnn set the initial system load (ISL) start address to
nnn in the volume label. This is useful when
building boot media for Series 700/800 systems.
-lnnn specifies the length in bytes of the ISL code in
the LIF volume.
-ennn set the ISL entry point to nnn bytes from the
beginning of the ISL. For example, specifying -
e3272 means that the ISL entry point is 3272
(decimal) bytes from the beginning of the ISL
object module.
-Knnn forces the directory start location to be the
nearest multiple of nnn x 1024 bytes from the
beginning of the volume. This is necessary for
booting Series 700/800 systems from LIF media.
-n xxx Sets the volume name to be xxx.

It turns out the native cc and our current gcc produce series 700
output, so in this case it runs till if fills up the hard disk.

*
* Description: low level support for gdb debugger. $
*
* Considerations: only works on target hardware $
*
* NOTES: See Below $
*
* 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
*************
*
* 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
*
* ? What was the last sigval ? SNN (signal NN)
*
* bBB..BB Set baud rate to BB..BB OK or BNN, then sets
* baud rate
*
************
* 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

* This is a modified gmon.c by J.W.Hawtin <oolon@ankh.org>,
* 14/8/96 based on the original gmon.c in GCC and the hacked version
* solaris 2 sparc version (config/sparc/gmon-sol.c) by Mark Eichin. To do
* process profiling on solaris 2.X X86
*
* It must be used in conjunction with sol2-gc1.asm, which is used to start
* and stop process monitoring.
*
* Differences.
*
* On Solaris 2 _mcount is called by library functions not mcount, so support
* has been added for both.
*
* Also the prototype for profil() is different
*
* Solaris 2 does not seem to have char *minbrk which allows the setting of
* the minimum SBRK region so this code has been removed and lets pray malloc
* does not mess it up.
*
* Notes
*
* This code could easily be integrated with the original gmon.c and perhaps
* should be.
