Error in Register View using DSF MI for MIPS

Build ID: I20080617-2000

Steps To Reproduce:
1) Create a sample MIPS ELF project executable using any MIPS compiler. I have used MIPS SDE Lite compiler. 
2) Use DSF C/C++ Remote Application debug launch to debug the built application using MIPS target using a cross compiled MIPS gdb (based on gdb 6.8) and a MIPS GDB Server which can communicate with MIPS target using an EJTAG probe. 
3) I am able to connect to the target successfully. But the register view lists lot of “Unknown” registers with value as “Error: Failed to execute MI command: -data-list-register-values x 0 Error message from debugger back end: bad register number”  before and after the normal MIPS registers. (see attached screen shot) 
 
  When I tried to debug MIPS target with CDT Hardware Debugger launch configuration (which uses the CDI MI implementation) using the same gdb and GDB Server this behaviour was not there. 



More information:
I checked the output of -data-list-register-names MI command and I can see lot of empty strings(“”) in the register name list before and after MISP register names. 

Is it some difference in the way DSF MI and CDT MI implementation interprets the output of -data-list-register-names is causing the issue? 

Attached the debug logs for both DSF and CDI.
