With
GNU gdb 20000305
"--host=i686-pc-cygwin --target=sh-coff"
the command "set architecture sh2", causes a core
dump.
Â
I believe it
is because the sh_processor_type_table[] in sh-tdep.c does not include an entry
for the sh2. Adding an entry fixes the problem.
Â
The sh1 and
sh2 processors share the same register names.
Â
The following
snippet shows the necessary changes.

Robert.

A core dump or an internal_error ?
Anyway, I've applied the patch. Thanks!
