Export target information to environment.
(_gdbtk_xvfb_init): New proc to start Xvfb if available and
necessary.

a path acceptible as an argument to a tcl command.
(_gdbtk_export_target_info): New proc to export target info
into the environment for gdbtk testing.
(gdbtk_done): New proc to signal end-of-test.
* lib/gdb.exp (gdb_skip_float_test): New proc. Skip test if
no floating point support.
(gdb_skip_stdio_test): New proc. Skip test if no stdio support.
* gdb.base/call-ar-st.exp: Use above procs to skip tests.
* gdb.base/call-rt-st.exp: Ditto.
* gdb.base/call-strs.exp: Ditto.
* gdb.base/sizeof.exp (check_sizeof): Skip if no printf support.
* gdb.base/varargs.exp: Skip entire test if no printf support.
* gdb.base/ending-run.exp (Step to return): Skip if no printf supt.
* gdb.base/shlib-call.exp: Skip several tests if no printf support.
Add support for a variable object that tries to evaluate itself in
the currently selected frame, rather than in a fixed frame.
* wrapper.c,h (gdb_parse_exp_1): Added a wrapper for
gdb_parse_exp_1.
* varobj.h: Added USE_CURRENT_FRAME to varobj_type & changed def'n
of varobj_create.

variable's type has changed (for current frame variables).
(varobj_update): Handle the case where the variable's type has
changed.

been installed yet.
(new_root_variable): Initialize use_selected_frame variable.
(value_of_root): This is where most of the work to handle "current
frame" variables was added. Most of the complexity involves
handling the case where the type of the variable has changed.
(varobj_create): Add a "type" argument, to tell if the
variable is one of these "current frame" variables. Also protect
call to parse_exp_1 from long jumping.
* mi-var-block.exp: The error report from varobj_create changed
since I am now trapping parse_exp_1 errors. Change the tests to
match the new error message.
* mi-var-child.exp: Ditto.
* mi-var-cmd.exp: Ditto.
* lib/gdb.exp: Fix the gdbtk_start routine to correctly find all
the library directories.
* gdbtk-varobj.c (variable_create): Pass the correct
"how_specified" flag to the varobj_create routine.

suppress_flag has been set.
(gdb_step_for_stub): Check for gdb,use_breakpoint_for_stub
target feature.
(gdb_run_cmd): Look for gdb,do_reload_on_run target feature--if it
exists, reload the executable and do a "continue" instead of
doing a jump.
(runto_main): Use gdb_step_for_stub.
* gdb.base/break.exp: Use gdb_step_for_stub. Also, rename certain
tests to have unique names.
* gdb.base/callfuncs.exp: Ditto.
* gdb.base/commands.exp: Ditto.
* gdb.base/default.exp: Ditto.
* gdb.base/help.exp: Ditto.
* gdb.base/list.exp: Ditto.

similar tests.

* gdb.c++/cplusfuncs.cc: Ditto.
* gdb.c++/virtfunc.cc: Ditto.
* config/monitor.exp: Keep track of the last file we saw, rather
than trying to get the info from gdb.
* gdb.fortran/types.exp: Move comment to previous line.
Fixes for TCL8 miscellaneous problems, plus other changes.
if we can't get a debug format from GDB (we may be testing an
older GDB). Use a 10 second timeout when checking for the format.
* gdb.stabs/weird.exp: Fix quoting.
until it has been modified to work with the new testsuite.
* gdb.*/*.exp: Instead of causing 1 unresolved test when the
testcase won't compile, cause all of the testcases in the file to
fail instead.
* lib/gdb.exp(gdb_suppress_entire_file): New procedure.
(gdb_clear_suppressed): New procedure.
(gdb_stop_suppressing_tests): Only clear suppress_flag if
it contains a positive value.
(get_debug_format): New function to get debug format.
(debug_format): New global variable to hold last value set
by get_debug_format.
* gdb.base/list.exp: Call get_debug_format and expect some
tests to fail for DWARF 1 and COFF formats.
* gdb.c++/ptype.exp: Ditto.
* gdb.c++/classes.exp: Ditto.
* gdb.c++/cplusfuncs.exp: Ditto.
* gdb.c++/inherit.exp: Ditto.
* gdb.c++/templates.exp: Ditto.
* gdb.c++/virtfunc.exp: Ditto.
host doesn't have a currently-open connection.
* config/sparclet.exp: Cleanups and fixes to make it generic for
any gdb stub target. Handle cases where gdb doesn't respond when
interrupted in a sane fashion.
* config/m32r.exp: Load sparclet.exp instead of trying to do the
same thing in a totally different way.
* config/monitor.exp: Pass in timeouts to gdb_expect instead of
setting "timeout".
(gdb_start): We set the global gdb_prompt variable in
default_gdb_init now.
initialize.
(default_gdb_init): New procedure; allow gdb_init to be overridden
by a target configuration file.
(gdb_expect): Pass the timeout to remote_expect.
* config/dos.exp(dos_wait): Add timeout parameter.
* lib/remote.exp(remote_expect): Add timeout parameter.
(remote_wait): Ditto.
(standard_wait): Ditto. Also give up if the program outputs
more than 512,000 bytes.

timeout variable.
