7f4352410f Only compile in solib_add_common_symbols for non-SVR4 (SunOS) shared libs. 1992-01-15 18:01:42 +00:00

* 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.

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.

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.
See the ChangeLog for details.

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.

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.

e1ce8aa5ed The list of changes is too long to fit in the cvs log (since it truncates!).
Look at the ChangeLog for Apr 30 and May 1.

2403f49b37 * blockframe.c, frame.h (reinit_frame_cache): New function.
solib.c (solib_add), symfile.c ({,add_}symbol_file_command):
	Use it.

d0237a54e5 * Shared libaray/corefile changes from Peter Schauer:
core.c (core_close): Call CLEAR_SOLIB.
	(core_open): Remove comment about "should deal with shared lib".
	(core_xfer_memory): If we can't xfer the usual way, try the
	shared libraries.
	solib.c (so_list): New fields so_bfd and so_sections{,_end}.
	(find_solib): Use solib_map_sections to get ld_text.
	(solib_map_sections, solib_xfer_memory): New functions.
	(clear_solib): Free so_sections and close so_bfd.
	tm-sunos.h: Add solib_xfer_memory, solib_add.

b3fdaf3d36 * symfile.c (symbol_file_add): Add comment.
solib.c (solib_add): Don't malloc name passed to symbol_file_add.
