* lib/gdb.exp(gdb_step_for_stub): New function.
(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. * gdb.base/opaque.exp: Ditto. * gdb.base/printcmds.exp: Ditto. Use a loop to emit multiple similar tests. * gdb.base/setshow.c: Add set_debug_traps/breakpoint calls. * 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.
