SH Debugging Question

[Jmills at TGA.com (John Mills)]

I have built the .../tests/samples/hello/init.c for the 'sh-rtems' target,
as the first step in porting to the SH-2.

1) Can I run the executable under a version of 'gdb' built with RTEMS
patches? What files or macros will I need to define my target hardware
(which can be any viable configuration)?

2) I build 'sh-hms-gdb' and 'sh-hms-run' from the GNUPro and eCos toolsets.
'info architecture' replies:
'Available architectures are:
  sh sh3 sh3e sh4'
'sh-hms-gdb' seems to load the sample OK, will list symbols and 'Init()'
source, and sets breakpoints. Can I use this combination to run the "Hello"
test?

Should I recompile parts of RTEMS with "-g" set to add debugging data to the
object? Which parts would folks suggest?

I'm working through the "plumbing" for SH-2 interrupt vectors, CPU
registers, etc., but wanted to see some sign of existing life in the SH-1
build meanwhile.

Thanks for any suggestions.
