2670f34d21 Relocate symbols using an array of section_offsets, rather than a
single `addr' or `offset'.  This makes Solaris-2 support work, and
permits better VxWorks (and maybe xcoff) support later.  See ChangeLog.

4c7c6bab1f * dbxread.c (process_one_symbol): Ignore N_MAIN, N_ENDM for Solaris.
* partial-stab.h:  Ignore N_ENDM.

for function types; move into "function" cases in switch statement.
(define_symbol: 'f', 'F', 'P'):  Process all parameter types
in case they define new type numbers.  But ignore them (FIXME).

	target.c, values.c:
	Replace bzero() use with memset(), which is more standard and can
	take advantage of gcc's builtin functions for increased performance.
	* i386-tdep.c, main.c, valprint.c:
	Replace bcmp() use with memcmp(), which is more standard and can
	take advantage of gcc's builtin functions for increased performance.

f70be3e45a COFF changes for dealing better with EPI 29K C compiler output.
* coffread.c (record_minimal_symbol):  Pass the minsym type to it.
Callers changed.
(coff_end_symtab):  Sort blocks if needed.  Complain if misordered.
(read_coff_symtab):  Move patch_opaque_types call from
coff_symfile_read.  Restrict it to symtabs from this objfile.
(process_coff_symbol: C_TPDEF):  Don't put ordinary foward
references on opaque type chain; just let coff_lookup_type handle 'em.
(decode_type):  Complain about tagndx values on
non-struct/union/enum types, which the EPI compiler tends to produce.

* symtab.c (list_symbols):  Make minimal symbol variable-finding work.

* tm-68k.h (FIX_CALL_DUMMY): Avoid alignment and byte order
dependency.

* elfread.c (elf_symfile_read):  Update bfd_elf_find_section
usage to match new prototype.  Include libbfd.h to get prototype.

346168a2c6 * elfread.c (record_minimal_symbol_and_info): Kludged to put
extra info in the minimal symbol.
(elf_symtab_read):  The extra info is the size of an ELF object,
which was kludged to us in the `udata' field of the BFD symbol.
Gag me with a crowbar...
(elf_symfile_read):  Keep track of both the absolute load address,
and the offset between load addr and symbols.  Handle STABS as
well as DWARF sections, passing the absolute load address to
elfstab_build_psymtabs.

* objfiles.c (free_objfile):  Eliminate storage leaks.  Contributed
by <Peter.Schauer@regent.e-technik.tu-muenchen.dbp.de>.
* symfile.c (symfile_bfd_open):  Comment where name is freed.
* symmisc.c (extend_psymbol_list):  Comment where list is freed.

6b80138803 Changes in procfs.c to fix bug with inferior's siginfo struct getting

3b0b92207c * elfread.c (elf_symtab_read): Use xmalloc, not bfd_xmalloc.
* exec.c (build_section_table):  Don't abort if no sections.
* sparc-tdep.c (single_step):  Lint.
* utils.c (mrealloc):  Handle realloc (0, size) case here.

5e2e79f859 Many changes, most related to creating entry point information on a per-objfile
basis.  See comments in objfiles.h and details in ChangeLog.  Also remove
redundant definitions of FRAME_CHAIN_VALID from most of the tm-* files and
use a default definition in frame.h.

80d68b1d49 * coffread.c, mipsread.c, xcoffread.c, coffread.c, dbxread.c,
elfread.c (coff_symfile_finish):  Add function, prototype, and
	add to the xxxx_sym_fns struct for each file type.  Also reformat
	the xxxx_sym_fns vector to a standard format and add comments.
	* coffread.c, mipsread.c, xcoffread.c, coffread.c, dbxread.c,
	elfread.c (xxx_symfile_new_init, xxx_symfile_init, xxx_symfile_read):
	Pass pointer to struct objfile rather than pointer to sym_fns.
	Change references inside each function accordingly.  Allocate any
	symbol file specific info in the per-objfile memory region.
	* dbxread.c (free_and_init_header_files):  Break function into
	free_header_files(), called from dbx_symfile_finish(), and
	init_header_files(), called from dbx_new_init().
	* dbxread.c (dbx_new_init):  Move deallocation things to new
	dbx_symfile_finish function.
	* elfread.c (elf_new_init):  Call buildsym_new_init().
	* objfiles.c (free_objfile): Call the appropriate symfile_finish()
	routine for the objfile before deallocating other stuff.
	* sparc-tdep.c (get_longjmp_target):  Cast target_read_memory arg.
	* symfile.h:  Move struct sym_fns to before struct objfile def.
	Add sym_finish function pointer and change prototypes of other
	function pointers to reflect passing struct objfile pointer rather
	than struct sym_fns pointer.
	* symfile.c:  Remove now obsolete symtab_fns pointer.
	* symfile.c (symfile_init):  Renamed to find_sym_fns, and now only
	locates the correct sym_fns struct for the given objfile.
	* symfile.c (syms_from_objfile, symbol_file_add):  Restructured
	for better support of mapped symbol tables.
	* symfile.c (symbol_file_command):  Remove obsolete code using
	symfile_fns.
	* symfile.h:  Remove duplicate declarations for symfile_objfile,
	entry_point, and object_files.
	* target.c (target_info):  Compare symfile_objfile to NULL.
	* xcoffread.c (aixcoff_new_init):  Move deallocation stuff to
	aixcoff_symfile_finish().

* All GDB files that #include defs.h: Removed stdio.h.
	(defs.h): #include stdio.h.

This has been tested by building GDBs for all targets hosted on Sun4.
None of the build problems were related to stdio.h inclusion.  (n.b.
many configurations don't build for other reasons.)

021959e249 * xm-sun3os4.h, xm-sun4os4.h: Enable HAVE_MMAP.
* minsyms.c (install_minimal_symbols):  Add bunches to any
existing minsyms in the objfile.  Avoid extra mallocation
by working directly in the obstack.  Remove ignored `mainline' parm.
* coffread.c, dbxread.c, elfread.c, mipsread.c, solib.c, symtab.h,
xcoffread.c:  Change all callers.
* FIXME:  We should be able to eliminate MAINLINE from all the
symbol readers now, with a small bit of work.

* valops.c, value.h:  Lint.
* remote-vx.c:  Add missing break; statement.  Bugfix by
Michael Sclafani, <sclafani@src.dec.com>.

d35bf52d93 Fix code in elf_symtab_read which attempts to read the standard ELF
symbol table and add symbol information to the misc function vector.
This allows minimum functionality with non -g compiled code, and is
vital for use with shared libraries (non of which are currently
compiled with -g).

Note to anyone doing any SVR4/gdb work.  This bug was introduced into
gdb just prior to the gdb 4.4 release, thus any versions currently
in the field will have broken shared library support since no symbol
information at all will be available for the shared library.  This
fix, along with one about to go into bfd's elf.c should fix that
problem.

fb18285098 Minor rewording of message containing name of program that generated a
core file (core.c), permanently remove the register_addr() stub (elfread.c),
move a misplaced #endif (procfs.c), and add fetch_core_registers func for
core file support (procfs.c).

abefb1f107 * infrun.c: Fixed typo in comment.
* utils.c:  All the v*fprintf emulation is now in libiberty,
	so we can get rid of some junk.
	* xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
	xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
	* m68k-pinsn.c (print_insn_arg):  Support BB/BW/BL
	type operands, as used by branch instructions.
	* gmalloc.c: Fix prototype of memcpy.
	* elfread.c: Comment out register_addr, since it conflicts
	with the one in coredep.c.
	* buildsym.h:  Remove extern declarations of two functions
	that are really static in buildsym.c.
	* tm-mips.h: Add symbolic names for more registers.
	* mips-xdep.c (store_inferior_registers): Use new register names.
	* xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
	only used for core files, not ptrace.  Therefore,
	the KERNEL_U_ADDR hack is no longer needed.
	The mapping to ptrace number is now in in mips-xdep.c.
	* mips-xdep.c:  Define REGISTER_PTRACE_ADDR (using the
	mapping from the old REGISTER_U_ADDR), and use it
	in {fetch,store}_inferior_registers.
	* mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
	* mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
	Save/restore FP regs correctly (?).
	* dbxread.c: Remove duplicate define_symbol and type_synonym_name
	(these had been previously moved to buildsym.c).
	Hence, define_symbol becomes extern instead of static.
	* buildsym.c (read_struct_type):  Comment out bogus handling
	of C++ operator methods.  Minor hacking of reading of class
	contexts. Make define_symbol non-static, so dbxread.c can call it.
