>Description:
The simulator works fine, but gdb seems to unable to handle breakpoints / stop the simulator. It will stop with:

(gdb) b Suite_SuiteGetCmdLine
Breakpoint 1 at 0x8001cb7c: file suite_misc.c, line 55.
(gdb) run
Starting program: /home/csc/src/aos64cvs/aos64core/build/mips-gdbsim/images/image.elf

Program received signal SIGTRAP, Trace/breakpoint trap.
warning: Warning: GDB can't find the start of the function at 0xffffffff.
0xffffffffffffffff in ?? ()
>How-To-Repeat:
Compile gdb/insight for mipsisa64 target. Compile some mips64 program. Set a breakpoint somewhere. run it.

    Looks like a gdb bug. Please submit bug report in gdb. [Or email gdb@sources.redhat.com.] You will need to send them a complete dialog of the session. They'll want to know what you're attempting to talk to if you're not using the simulator.
