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.)

functions for which no definitions or prototypes are provided in
any currently included gdb or host environment header files.

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.

Per Bothner
ee17fd3437 * mipsread.c (parse_partial_symbols): Handle dependencies
between partial symbol tables (when not doing stabs-in-ecoff).
	(This used to be handled by parse_fdr, but parse_fdr was
	incompatible with handling stabs-in-ecoff, so the code
	was re-written to not use parse_fdr.  Unfortunately,
	the logic to handle dependencies was overlooked.)
1992-02-06 23:24:30 +00:00
Steve Chamberlain
1f46923ff4 * coffread.c (read_enum_type): Use the size of a target int when

	* defs.h: added new #define for TARGET_PTR_BIT, defaults to size
	of target int.
	* h8300-tdep.c, remote-hms.c, tm-h8300.h: too many changes to count
	* symtab.c (lookup_reference_type, lookup_ptr_type): use
	TARGET_PTR_BIT to determine size of a pointer
	* values.c (unpack_long): when unpacking a REF or a PTR don't
	assume the size of the type.

778c358df8 * mipsread.c (parse_symbol): Avoid clobbering enum pointer when

only assuming union if multiple members have offsets of zero.
