Hello all,
Once i want to develop a new simulator for my new architecture,
i can try to port the existing gdb target(ex:arm) for my new architecture.
I think that it is not an easy task.
So, does anyone knows that a tool that can generate the simulator for new
architecture(ISA).
thanks a lot!!
best regards

Hi
We need to have a list of which an ISA simulator is written by which
tool. For example, is it true that only PPC and MIPS were written in
IGEN?
Thanks

There are two tools, CGEN <http://sources.redhat.com/cgen/> and
IGEN, that generate simulators.
But a GDB port for a new architecture has to be written by hand.

PPC is handwritten . Its called PSIM if I am not wrong .MIPS is written
using IGEN. You could look at cgen too for a simulator infrastructure.
cgen is used for the m32r architecture. You could take a look at the
cgen directory in the src directory on sources.redhat.com for more info.

PSIM was written using an earlier version of IGEN. Other igen examples
are the mn10300 and v850.
