Jim Blandy e8930304b2 * solib.c (solib_add): Move all the code for loading symbol tables
below the code to sort out additions and removals.  That way, we
always catch all loaded shared libraries whose symbols we haven't
grabbed yet.

* solib.c (solib_add): Don't try to free a shared object's objfile
if it doesn't have one.  Duh.

* solib.c (solib_add): If a pattern was given, but it doesn't
match any currently loaded shared libraries, print a message;
don't just be silent.

* solib.c (open_symbol_file_object): to sneak an int argument
        past catch_errors, instead of casting it to a pointer, simply
        pass it by address.
2000-03-24 23:49:10 +00:00
Kevin Buettner 62557bbcee Make sure section addresses from a shared object are correctly set in
a new struct objfile.

Jim Blandy c2d3b4ed35 * solib.c (solib_add): Delete debugging code. 2000-03-17 20:12:23 +00:00
Jim Blandy 15588ebb21 * solib.c (current_sos): Be more careful about freeing the new
so_list node if an error occurs.
2000-03-16 23:12:42 +00:00
Jim Blandy 07cd4b9723 Deal with the inferior unloading shared objects.
* solib.c (current_sos): New function, replacing find_solib.
(find_solib): Deleted.
(free_so): New function.
(clear_solib): Call free_so, instead of writing it out.
(solib_add): Rewritten: compare the inferior's current list of
shared objects with GDB's list, and do the required loads and
unloads.
(info_sharedlibrary_command, solib_address): Don't use find_solib
to walk the list of shared libraries: call solib_add, and then
walk the list at so_list_head normally.
* objfiles.c (free_objfile): Don't call CLEAR_SOLIB, and don't
detach the core target.  These tasks are taken care of elsewhere.
* target.c (remove_target_sections): New function.
* target.h (remove_target_sections): New declaration.

* solib.c (symbol_add_stub): Check whether we've already created
an objfile for this shared object first, before doing all that
work to compute section addresses, etc.

* objfiles.c (unlink_objfile): Report an internal error if objfile
doesn't occur in the object_files list.

* solib.c (special_symbol_handling): Delete argument; it's not
used.

* solib.c (SOLIB_EXTRACT_ADDRESS):  New macro to extract addresses
from solib structures. Use it throughout solib.c, get rid of all
CORE_ADDR casts.
(struct so_list):  Change type of lmaddr to CORE_ADDR.
(first_link_map_member):  Change return value type to CORE_ADDR,
update callers.
(solib_add_common_symbols):  Change parameter type to CORE_ADDR,
update callers.
(open_symbol_file_object, find_solib):  Change type of lm variable
to CORE_ADDR.

(enable_break): For SVR4 systems, first try to use the debugger

read symbol tables.

Stu Grossman d261ece7ea Reference: gdb-pend/657
* target.c (target_read_string):  Create this routine to read null
terminated strings from the target.  It deals with running off the
end of memory elegantly as well.  solib.c (find_solib):  Use
target_read_string() to avoid problems with running off the end of
memory.
1992-01-15 00:40:30 +00:00
Fred Fish 431df2ebac * solib.c (locate_base): Fix uninitialized variable that was
causing return of random value to callee.

	* config/mh-amix, config/mh-i386v4:  Change to find alloca by
	compiling and linking alloca.c, even when it is not strictly
	required.  Also arrange to link with -ltermlib rather than
	-ltermcap.

	* Makefile.in:  Move TERMCAP definition to prior to inclusion
	of host makefile fragments so it can be overridden.
1991-12-23 03:43:48 +00:00
Fred Fish f8b76e70b7 Numerous small changes and a complete reorganization of solib.c, to support
SVR4 shared libraries in a manner very close to the original SunOS support.

John Gilmore 06b6c733ae Fix some infrastructure to be able to cope with host and target
machines with different sized basic types (ints, ptrs, etc).
(Idea from pierre@la.tce.com (Pierre Willard).)

* value.c (value_from_longest):  Rename from value_from_long.
Handle pointer types as well as integers, so that targets with
different pointer sizes from the host can be accomodated.
* breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
valarith.c, valops.c, valprint.c, value.h, values.c:  Rename
uses of value_from_long to value_from_longest.
* eval.c, findvar.c, printcmd.c, valarith.c, valops.c:  Pass
the correct pointer type to value_from_long{est}.

* remote-vx.c:  Remove obsolete code for calling functions via
vxworks kludge interface (it referenced value_from_long).

* valops.c (value_string):  Find malloc with lookup_misc_func, not
raw search.

* breakpoint.c, remote-vx.c: Reword strings printed by
catch_errors callers.
1991-09-06 07:09:40 +00:00
John Gilmore bdbd5f5086 Make writing to files work properly. (Fixes to BFD are also needed.)
* 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.
