Hello,
With the mips-sde-elf target I observe a problem with a test script from
the binutils testsuite looping as follows:
(gdb) file tmpdir/striprog
Reading symbols from [...]/tmpdir/striprog...(no debugging symbols found)...done.
(gdb) break _exit
Function "_exit" not defined.
Make breakpoint pending on future shared library load? (y or [n]) break
exit
Please answer y or [n].
Make breakpoint pending on future shared library load? (y or [n]) break
abort
Please answer y or [n].
Make breakpoint pending on future shared library load? (y or [n]) target
mdi 15:2
Please answer y or [n].
Make breakpoint pending on future shared library load? (y or [n]) WARNING:
Unable to connect to 15:2 with GDB.
quit
Please answer y or [n].
Make breakpoint pending on future shared library load? (y or [n])
Rebooting mipssim-sde
In this case the binary has been stripped, so no surprise there is no
_exit symbol to place a breakpoint on. As seen from config/gdb-comm.exp
the breakpoint is used to catch a runaway debugger only, so it is safe to
skip it if it cannot be set straight away; the return status from the
function may be used for further processing if need be.
The following patch fixes the problem for me.
2009-06-08 Maciej W. Rozycki <

* config/gdb-comm.exp (gdb_comm_add_breakpoint): Handle pending
breakpoints.
Please apply.
