Problem identified by Ulrich Weigand.
* gdb.base/a2-run.exp: Use gdb_skip_stdio_test.
* gdb.base/corefile.exp: Expect the message "Program is being
debugged already" when we send the "corefile" command, since
the preceeding gdb_load may have connected gdb to a remote target.
* gdb.base/display.exp: Disable hardware watchpoints if new
board info variable "no_hardware_watchpoints" is true.
Replace single-letter commands with more readable ones.
* gdb.base/recurse.exp (recurse_tests): Disable hardware watchpoints
if new board info variable "no_hardware_watchpoints" is true.
* gdb.base/restore.exp (restore_tests): Call gdb_skip_stdio_tests
to see if stdio (printf) testing is possible.
* gdb.base/watchpoint.exp: Disable hardware watchpoints if new
board info variable "no_hardware_watchpoints" is true. Use new
proc "gdb_skip_stdio_tests" to see if printf tests are possible.
* gdb.base/recurse.exp: Run tests for all targets.
* gdb.base/so-impl-ld.exp: Added wildcard to handle the
gnu-oldld case on ARM.
* gdb.base/watchpoint.exp (test_stepping): Clear xfail
for ARM targets.
* gdb.base/help.exp: update help msg for INFO ADDR; add help test
for INFO SYMBOL; add help tests for OVERLAY commands.
* gdb.base/default.exp: add tests for INFO SYMBOL command;
add tests for OVERLAY commands
* gdb.base/overlays.c overlays.exp foo.c bar.c baz.c grbx.c ovlymgr.h

* gdb.base/watchpoint.c: turn on complex watchpoint test for M32R.
exit status and/or results from the target.
* gdb.base/watchpoint.exp, gdb.base/langs.exp: Likewise.
* lib/gdb.exp: Remove old (now bogus) initialization of
noinferior, noargs, noresults and nosignals.
More cleanups for new testing framework.
* config/slite.exp: Try to connect multiple times to the board
before rebooting. Only send a "monitor run" if need_monitor_run
is set.
* gdb.base/break.exp: Don't do the "stub continue" test if
the target has gdb_stub set.
* gdb.base/callfuncs.exp: Increase the timeout.
* gdb.base/interrupt.exp: Don't even try to compile the testcase
if the target has gdb,noinferiorio set.
* gdb.base/list.exp: Increase match_max to 10000 characters.
* gdb.base/sigall.exp: Check for gdb,nosignals on the target.
* gdb.base/watchpoint.exp: Check for gdb,noinferiorio on the
target.
* lib/gdb.exp(gdb_run_cmd): Fix for targets that use stubs.
Misc fixes for sparclite and SH.
parenthesis in case it contains multiple regexps separated
with |.
Fixes last nights native failures.
* gdb.base/watchpoint.exp: Use gdb_test.
* gdb.base/default.exp: Ditto.
More improvements.
* gdb.base/signals.exp: Check for a gdb,nosignals feature of
the target.
* gdb.base/watchpoint.exp: Fix regexp.
Random miscellaneous fixes. Gotta dig up all these global variables someday..
if $noresults if nonzero.
* gdb.base/langs.exp: Likewise.
* gdb.base/watchpoint.exp: Likewise.
For proelf targets were we can't even tell if a process exits.
config/rom68k.exp: New tcl glue for the appropriate monitors.
These all just end up calling monitor.exp.
* config/monitor.exp (gdb_target_monitor): Handle `Connection
refused' by retrying. Cleanup some timeout issues.
* (gdb_load): Reduce timeout. Cleanup some timeout issues.
* lib/gdb.exp (gdb_test gdb_test_exact): Upvar timeout so that
callers don't have to set/restore global timeout variable.
* The following set of changes centralizes management of the global
timeout variable. This way, it can be set in one target dependent
place instead of dozens of places scattered throughout the test suite.
If you need to lengthen a timeout, then you should either set timeout
in one of the config/{target}.exp files, or multiply it by a factor.
Setting it to an absolute value is always going to lose for some
targets.
* gdb.base/a1-selftest.exp (test_with_self): Only use local timeout.
* gdb.base/callfuncs.exp (do_function_calls): Don't set timeout.
* gdb.base/funcargs.exp: Don't set timeout.

test_print_array_constants): Don't set timeout.
* gdb.base/ptype.exp: Don't set timeout.
* gdb.base/recurse.exp: Don't set timeout.
* gdb.base/return.exp: Don't set timeout.
* gdb.base/watchpoint.exp: Don't set timeout.
* gdb.c++/classes.exp (do_tests): Don't set timeout.
* gdb.c++/virtfunc.exp (test_virtual_calls): Don't set timeout.
* TODO: Remove item about printing variables in nodebug.exp. Add
item about enabling tests which are only run on some targets.
* gdb.base/watchpoint.exp: Various cleanups (make each test pass or
fail, make test names unique, use new gdb_test convention
regarding pattern, use gdb_test more, etc.).
