Multi-arch and simulators questions

Multi-arch and simulators questions

[Stephane Carrez]

Hi!

I'm trying to multi-arch the 68hc11 gdb target.

It has a simulator which uses the common framework.

Is there anything to do on that?

How can we integrate several simulators in GDB?

Have you ever tried gdb with both mips and sh for example?

What would be the configure command to get two targets in the same gdb?

Thanks,
	Stephane

That's just really hard with the sim/common framework - it is in a
similar shape as gdb was before multi-arch.  We may have some help to
offer with this problem on the way soon - hang on.

No.  For the moment GDB continues to assume that there is only one
simulator.

For the MIPS, that is separatly multi-arched.  N simulators are
accessible via that one interface.

To be done. People are currently only using multi-arch to handle ISA
variants.
When it happens, simulators will make for an interesting stumbling block
:-)

In theory, GDB would recognize the --enable-targets=... command just
like BFD.

Hope the process isn't too painful.
