            Bug ID: 17026
           Summary: Cannot backtrace on executable generated by TI C6x
                    compiler
           Product: gdb
           Version: 7.7
            Status: NEW
          Severity: normal
          Priority: P2
         Component: backtrace
          Assignee: unassigned at sourceware dot org
          Reporter: ubrindis at ti dot com

GDB cannot handle backtracing on executables generated by the TI C6x compiler.
When running the bt command this is the frame information that is shown 

Program received signal SIGTRAP, Trace/breakpoint trap.
0x008105e6 in $C$L4 () at ../main.c:54
54      ../main.c: No such file or directory.
(gdb) bt
#0  0x008105e6 in $C$L4 () at ../main.c:54
PC not saved

If the command "info frame" is run, sometimes this is the output - 
(gdb) info frame
Stack level 0, frame at 0x81b4b8:
 PC = 0x8105e6 in myTask (../main.c:54); saved PC = <not saved>
 called by frame at
frame.c:472: internal-error: get_frame_id: Assertion `fi->this_id.p' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)

I have included a test executable.

This was found by compiling GDB for --host=arm-linux-gnueabi
--target=tic6x-*-elf
