rather than jumping back to command level. Modules that want to print
their own warnings without calling warning() can call warning_setup() to
handle the terminal compatibly with warning() and error().
first.
* main.c (main, print_gnu_advertisement, print_gdb_version):
Reformat legalese so it always prints, but acts as an "I'm here"
message while symbols are being read. If any errors occur,
print a few newlines to set off the message and start it at the
left margin. Remove mention of "help" command, and don't yak about
symbol reading.
(catch_errors): Error string is now printed first in case of
error, not last.
* command.c (undef_cmd_error, lookup_cmd): On undefined command,
suggest the "help" command.
* Makefile.in (VERSION): Set to 4.0.2.
* core.c (core_open): Open file ourselves, read or r/w, depending on
write_files. Use bfd_fdopenr.
* gdbcore.h (write_files): New variable.
* exec.c (write_files): Define variable, add set&show for it.
(exec_file_command): Use write_files to open for read or r/write.
Make shared library reading happen automatically. These changes
are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
* inferior.h (stop_soon_quietly): Add to exported variables.
* infrun.c (child_create_inferior): call solib hook, if defined.
(child_attach): call solib hook, if defined.
* solib.c: Include inferior.h. Add from_tty to so_list as kludge.
(find_solib): Use lookup_misc_func rather than hand-rolled.
(symbol_add_stub): New stub for catch_errors.
(solib_add): Avoid output if !from_tty. Catch errors rather
than just calling symbol_file_add and bombing.
(solib_create_inferior_hook): Interface with the target process
to let it read and alloc shared libs, then figure out what it did.
* core.c (validate_files): Fix typo, soften warning.
(Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
* utils.c (fputs_demangled): Avoid duplicate printing if
demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
* infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
(Fix from pierre@la.tce.com (Pierre Willard).)
* main.c (catch_errors): Change argument to a char * from an int,
since a char * can point to a struct full of glop, but an int
is not guaranteed to be able to hold a pointer.
* breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
breakpoint_re_set_one, breakpoint_re_set): Adapt.
* core.c (core_open, solib_add_stub): Adapt.
* remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
* tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
it causes recursive calls to error() when used in cleanups.
To do so requires that we make it a function, so we do.
* sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
* utils.c (do_cleanups): Remove the current cleanup from the
chain *before* calling it, in case error() is called from it.
The result won't be pretty, but won't be an infinite loop either.
(long_options): Terminate with a zero element.
[Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
(gdb_readline): Make call-compatible with readline.
(init_signals): Improve comments re vfork vs. signal.
* utils.c (prompt_for_continue): Use new gdb_readline().
If we prompt for continuation, we don't let CR repeat the previous
command, once we get back to a prompt. It's too easy to keep
hitting CR, expecting "--more--" prompts, and have some long
command start repeating on you.
