Separate core functions along target vector in preparation for
native support. Functions above vector now live in core.c. Those
below in corelow.c.
* core.c (solib_add_stub, core_close, core_open, core_detach,
get_core_registers, core_files_info, core_ops): moved to corelow.c
(_initialize_core): removed addition of core_ops target.
* corelow.c: new file.
(solib_add_stub, core_close, core_open, core_detach,
get_core_registers, core_files_info, core_ops): moved from core.c
(_initialize_corelow): new function.
* gdbcore.h (core_open, core_detach): added prototypes.
(core_ops): add forward declaration.
* Makefile.in (SFILES_MAINDIR): add core.c
(OBS): add core.o
(TSOBS): change core.o to corelow.o

/* Core dump and executable file functions above target vector, for GDB.

regaddr to type CORE_ADDR.

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.

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.
