Except for the two m32r modules, this checkin is for
	overlay support.

        * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
        find_pc_sect_function(), find_pc_sect_partial_function(): new
        functions for debugging overlays; pc without section is ambiguous.
        * breakpoint.[ch]: add section pointer to breakpoint struct;
        add section argument to check_duplicates(); check section as well
        as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
        breakpoint_thread_match(), bpstat_stop_status()];
        add section argument to describe_other_breakpoints();
        use INIT_SAL() macro to zero-out new sal structures;
        make resolve_sal_pc() fix up the sal's section as well as its pc;
        match on section + pc in clear_command() and delete_breakpoint();
        account for overlay sections in insert_breakpoints(),
        remove_breakpoint() and breakpoint_re_set_one();
        all this to support overlays where a PC is not unique.
        * exec.c: change xfer_memory() to handle overlay sections.
        * findvar.c: change read_var_value() to handle overlay sections.
        * frame.h: declaration for block_for_pc_sect() [blockframe.c].
        * infcmd.c: jump_command() warns against jumping into an overlay
        that's not in memory.  Also use INIT_SAL() to initialize sals.
        * infrun.c: wait_for_inferior() sets a flag to invalidate cached
        overlay state information; Also use INIT_SAL() to init sals.
        * m32r-rom.c: modify load routines to use LMA instead of VMA.
        * m32r-stub.c: mask exit value down to 8 bits; screen out any
        memory read/writes in the range 600000 to a00000, and ff680000
        to ff800000 (hangs because nothing is mapped there); fix strcpy().
        * maint.c: maintenance command "translate-address" supports overlays.
        * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
        * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
        this constitutes gdb's internal overlay mapping table.  Add macro
        ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
        Add function find_pc_sect_section().
        * printcmd.c: modify print_address_symbolic() with overlay smarts;

	* regex.c (re_compile_fastmap, re_match_2):  Add remaining enum types
	and default to switches for completeness.
	* minsyms.c (lookup_minimal_symbol_text): Delete unused variable
	"trampoline_symbol".
	(prim_record_minimal_symbol_and_info):  Return NULL rather than trash.
	* elfread.c (elf_symtab_read):  Don't dereference NULL returns from
	record_minimal_symbol_and_info.
	* f-lang.c (saved_function_list_end):  Ifdef out unused variable
	that may be used someday.
	* f-valprint.c (f_val_print):  Remove unused local variable "straddr".

Kung Hsu cdd2212f75 * minsyms.c: add new function lookup_minimal_symbol_text, to look
for text symbol only.
	* breakpoint.c (create_longjmp_breakpoint): call
	lookup_minimal_symbol_text instead of lookup_minimal_symbol.
	* symtab.h: add lookup_minimal_symbol_text prototype.

Jim Kingdon 2d336b1b51 * config/sparc/tm-sun4sol2.h, dbxread.c: Rename
N_SO_ADDRESS_MAYBE_MISSING to SOFUN_ADDRESS_MAYBE_MISSING.
	* symtab.h (minimal_symbol) [SOFUN_ADDRESS_MAYBE_MISSING]: Add
	filename field.
	* elfread.c (record_minimal_symbol_and_info),
	minsyms.c, symtab.h (prim_record_minimal_symbol_and_info): Return
	newly created symbol.
	* elfread.c (elf_symtab_read) [SOFUN_ADDRESS_MAYBE_MISSING]:
	Set filename field of minimal symbol.
	* symmisc.c (dump_msymbols) [SOFUN_ADDRESS_MAYBE_MISSING]:
	Print filename field.
	* minsyms.c, symtab.h (lookup_minimal_symbol): New arg sfile.
	* symm-tdep.c, somsolib.c, hppa-tdep.c, c-exp.y, f-exp.y,
	m2-exp.y, nindy-tdep.c, m3-nat.c, irix5-nat.c, hpread.c,
	os9kread.c, breakpoint.c, alpha-tdep.c, valops.c, symtab.c,
	printcmd.c, dbxread.c: Change callers to pass NULL for sfile.
	* dbxread.c (process_one_symbol) [SOFUN_ADDRESS_MAYBE_MISSING]:
	Find address of function from minimal symbols.
	* partial-stab.h, case 'f', 'F': Call find_stab_function_addr
	instead of getting pst->textlow from the stab.
	* minsyms.c (find_stab_function_addr): New function.

Peter Schauer 02b40a193e * dbxread.c (process_one_symbol): Handle N_FUN symbols
for Sun acc 3.0 under SunOS4.

	Changes to improve handling of runtime common symbols
	under SunOS4.
	* minsyms.c (get_symbol_leading_char):  New routine to determine
	the leading symbol character for an objfile.
	(prim_record_minimal_symbol_and_info, install_minimal_symbols):
	Use it.
	* objfiles.h (rt_common_objfile):  New global, points to objfile
	containing the runtime common minimal symbols.
	* objfiles.c (free_objfile):  Mark rt_common_objfile as
	unallocated before freeing it.
	* solib.c (allocate_rt_common_objfile):  New routine to allocate
	an objfile for the runtime common minimal symbols.
	(solib_add_common_symbols):  Allocate an objfile for the runtime
	common symbols if necessary and put common symbols into it.
	Clean up code and comments.
	(solib_add, special_symbol_handling):  Cleanup comments regarding
	runtime common symbols.
	* stabsread.c (scan_file_globals_1):  New routine, contains
	old scan_file_globals code. Checks if there are any unresolved
	global symbols before starting the expensive minimal symbol table
	search.
	(scan_file_globals):  Now calls scan_file_globals_1 for the passed
	objfile and eventually for the runtime common objfile. Complains
	about any unresolved global symbols and removes them from the
	global symbol chain to avoid dangling pointers into the symbol
	table if the symbol table is reread.
