Hello,
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.
# Test Results #
Sim dejagnu tests were added specifically for openrisc and used to test
this. Please see the details of running the testsuite for sim below:
=== sim Summary ===
# of expected passes 18

- comment was flipped
- switched from saying macro to function
* Fixes to sim & testsuite patch
- removed 1996 copyrights throughout
- fixed 80 char column issues
- fixed comment typos
- fixed issue with '* current_cpu' vs '*current_cpu' throughout
- added comments about SR[LEE]
Changes since v4
* Added comments to most of the functions
* Implemented remainder fpu function
* Actually wire in fpu and error handling logic
* Added fpu test case
Changes since v3

Changes since v1
* Squashed sim patches into single sim patch
* Put Generated files in separate patch
* I have my sim/gdb copyright assignment complete
