How to map memory for SH simulator?

How to map memory for SH simulator?

[William A. Gatliff]

Guys:


I've seen the commands used to control the memory map for the powerpc
instruction set simulator:

http://sources.redhat.com/ml/gdb/2001-11/msg00137.html

I need to do the same thing for SH, but it doesn't look like the SH
simulator takes the same commands.  Where can I find the list of
commands supported by the SH instruction set simulator?


Thanks!

The sim/common family of simulators (sh, etc.) uses an alternate
syntax to specify additional simulated memory regions.  See the
"memory-region" option as listed in "% sh-elf-run --help" or 
"(gdb) target sim ... sim help":

Er, are you sure about this?

Uh, good point, thanks for pointing that out.  Sorry - I was thinking
of another sh simulator.  There are a few stragglers in sim/*,
including the old "sh", that don't use enough common code to do this
configuration in a uniform way.  This hegemony is what the sim/common,
and the later sid frameworks have been aiming to correct, but these
old ports just won't go away by themselves. :-)

Anyway, gazing at sim/sh/interp.c, there is a possibly useful "sim
set-memory-size NUMBITS" gdb command, with a similar unadorned
"sh-*-run PROGRAM NUMBITS" command line argument.
