I made a simple test on a recent cygwin native gdb built from CVS tree.

>(gdb) set archdebug 1

(gdb) set archdebug 1
Warning: command 'set archdebug' is deprecated.
Use 'set debug arch'.
Maybe this should also be changed on html, unless there are still some hidden differences...

afterr setting debug arch to 1

(gdb) file ./gdb
gdbarch_update: info.bfd_arch_info i386
gdbarch_update: info.byte_order 1 (little)
gdbarch_update: info.abfd 0xa035030
gdbarch_update: info.tdep_info 0x0
gdbarch_update: Architecture 0x0a0281f0 (i386) unchanged
Reading symbols from ./gdb...done.

Is this all that is  defined in i386-tdep.c ?
I see more set_gdbarch_****
calls in i386-tdep.c source, but they are not reflected here....

If I try to set debug arch to higher values I get lots of
output, but not much understandable...
