[PATCH v3 0/5] sim port for OpenRISC


Hello Again,

Please find attached the sim patches that allow to get a basic OpenRISC
system running.  This was used to verify the OpenRISC gdb port.

The main author is Peter Gavin who should have his FSF copyright in place.

Request for comments on:
 - The testcase has a few tests commented out. I do not plan to fix now,
   but hopefully be addressed after upstreaming.
 - Openrisc supports a l.rem instruction which has been implemented here
   using the drem() function from libmath.  It seems no other functions use
   libmath now, I hope this is ok.

Sim dejagnu tests were added specifically for openrisc and used to test
this.  Please see the details of running the testsuite for sim below:

# of expected passes            17

Thanks,
-Stafford
