testing GDB with the simulator

testing GDB with the simulator

[Joel Brobecker]

Hello,

Is there a way to run the GDB testsuite on the GDB simulator?
Perhaps with a specific board file, as explained in the GDB Wiki
for testing with the gdbserver? I just did some powerpc-specific
work, and had to test it on ppc-aix, which is extremely slow
with the machines that AdaCore has. I think I could save quite
a bit of time if I could do the testing on the powerpc simulator
and the powerpc-elf target. If possible, I'll be happy to contribute
a Wiki page for it.

Thanks,

Of course -- but I'm not sure I remember specifically....

In gdb/testsuite/config I see sim.exp and sid.exp

In /usr/share/dejagnu/baseboards I see many *-sim.exp 
baseboard description files including powerpc-sim and 
powerpcle-sim.

As well, I see /usr/share/dejagnu/config/sim.exp

Hope these get you somewhere close to the answer...

Take a look at this:
  http://gcc.gnu.org/simtest-howto.html

The page is stale, so some of those targets won't work.  But the same
instructions should generally work for GDB once you have a toolchain.
mips-elf, powerpc-eabisim, and arm-eabi are the most common targets
with working simulators.
