RE: new port

Florent,

I have also been porting to a new architecture, and recently solved similar
problems with next. The way next works is that, after a step, it checks
whether an extra frame has been added to the stack. If it has, and various
other checks are satisfied, then it places a breakpoint on the return
address and runs on. Otherwise it simply stops after the first step.

Try stepping into the function using stepi, stopping at its first
instruction, and then having a look at the stack frames (using bt and "info
frames"). If these look wrong then that is probably your problem.

Hi,

I work on porting GDB to a new arch.
I already ported GCC.

I meet some problems, I need help.

At the moment, I can use most of basic GDB commands.

I can set breakpoints and stop on them. I can set breakpoints on function
names.
I can step. I can read locals and registers.

When I use the command 'next', it should step and skip functions. The
problem is that
indeed it steps but it does not skip functions. It step into the function.

Please help.


Regards.

Florent
