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;
        modify address_info() with overlay smarts; add function sym_info()
        to support the INFO SYMBOL command (translate address to symbol(s));
        modify disassemble_command() to work on unmapped overlays.
        * source.c: use INIT_SAL() to initialize sals.
        * symfile.[ch]: change generic_load() to use section's LMA address
        instead of VMA address, for overlay sections.
        Add numerous functions for finding a PC's section / overlay,
        translating between VMA and LMA address ranges, determining if an
        overlay section is mapped, etc.  Add several user commands for
        overlay debugging.  Add support for a "generic" form of automatically
        reading overlay mapping info from the inferior (based on the default
        (simple) overlay manager which Cygnus provides as an example).
        * symtab.[ch]: add functions find_pc_sect_symtab(),
        find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
        for lookup; modify lookup_symbol and decode_line_1() to use them;
        modify find_function_start_sal() to account for overlay sections;
        add macro INIT_SAL() for initializing struct symtab_and_line.
        * target.c: fix a comment in the declaration of target_ops.

	* coffread.c dbxread.c elfread.c gdb-stabs.h objfiles.h:  Remove
	unnecessary cast for assignment of struct dbx_symfile_info.

	* exec.c (xfer_memory):  Handle transfers for user-specified

VARIABLES_INSIDE_BLOCK to OS9K_VARIABLES_INSIDE_BLOCK.
	* symfile.c (symbol_file_command): Check for (CORE_ADDR)-1, not
	(CORE_ADDR)0, from target_link, since that is what it uses.
	Process name at end, not during parsing (like we did before Kung's
	change), so that -readnow and -mapped can appear anywhere.
	Make text_relocation a local variable.
	* config/i386/i386os9k.mt: Fix comment.

Fred Fish 6c316cfd66 * inflow.c (new_tty): Temporarily ignore SIGTTOU when
disconnecting from controlling terminal, to avoid gdb hanging
	on SVR4.  Fixes bug reported by Oliver Okrongli.
	* procfs.c (PROC_NAME_FMT):  Change format to match default used
	by system, as suggested by Oliver Okrongli.
	* tm-68k.h (FRAME_FIND_SAVED_REGS):  Apply missing parentheses
	bug fix from Brent Townshend (bst%tt@cam.ORG).
	* c-exp.y (nonempty_typelist):  Fix memory overrun bug reported
	by turlais@rechser.total.fr.
	* dwarfread.c (decode_subscr_data):  Fix bug in calculation of
	length of non-zero lowerbound arrays.  Bug fix from Peggy Fieland.
	* objfiles.h (unlink_objfile):  Add prototype.
	* objfiles.c (unlink_objfile):  Add function.
	* objfiles.c (free_objfile):  Call unlink_objfile.
	* objfiles.c (allocate_objfile):  Call unlink_objfile on newly
	remapped objfiles.  Bug reported by hahn@sunshine.labs.tek.com.
	Also, discard old possibly bogus sf struct.
	* symfile.c (symbol_file_add):  Call init_entry_point_info() and
	find_sym_fns() for remapped symbol files, in case of any changes
	since the last mapping.

Fred Fish 2d6d969c61 Fix to dwarfread.c to target pointer and target long sizes, fixes for
mapped symbol file handling, and a couple of other misc small fixes.

John Gilmore 84ffdec2cb Create and use macros for iterating on symtabs, psymtabs, msymbols.
* minsyms.c (iterate_over_msymbols):  Remove; clunky and slow.
* symfile.h, symtab.h (iterate_over_msymbols):  Remove prototype
* coffread.c (coff_symfile_read):  iterate_over_symtabs => ALL_SYMTABS.
(patch_opaque_types):  Avoid dummy args and result.
* objfiles.c (have_partial_symbols, have_full_symbols,
have_minimal_symbols):  explicit iteration => ALL_OBJFILES; simplify.
(iterate_over_objfiles, iterate_over_symtabs,
iterate_over_psymtabs):  Remove, clunky and slow.
* objfiles.h:  Replace iterate_over_* prototypes with ALL_SYMTABS,
ALL_PSYMTABS, and ALL_MSYMBOLS macros.
* symmisc.c (dump_symtab, dump_psymtab, dump_msymbols,
dump_objfile):  Remove dummy args and results.  Move filename
comparisons to callers.
(printsyms_command, printpsyms_command, printmsyms_command,
printobjfiles_command):  iterate_over_* => ALL_*.  Compare filenames.
* symtab.c (lookup_symtab_1, lookup_symtab, lookup_partial_symtab,
lookup_symbol, find_main_psymtab, find_pc_symtab, sources_info,
list_symbols, make_symbol_completion_list):  Replace explicit
iteration with ALL_SYMTABS, ALL_PSYMTABS, or ALL_MSYMBOLS.
Eliminate Dijkstra flag crap, break out of loops with gotos.
(lookup_symtab_1):  Protect '/' tests from short filenames.
(cplus_mangled_symbol):  Move inline into lookup_symbol.
* xcoffexec.c (relocate_objfile_msymbols):  Remove poor hack.
(relocate_minimal_symbol):  Move inline to vmap_symtab.
(vmap_symtab):  Replace iteration with ALL_OBJFILES,
iterate_over_msymbols with ALL_MSYMBOLS.

Misc cleanup prior to release.

* dwarfread.c (dwarf_build_psymtabs):  Remove mainline test.
* mipsread.c (compare_symtabs, compare_psymtabs):  Remove, unused.
* mipsread.c:  Add prototypes for all static functions.

* symmisc.c (dump_symtab_lines, dump_symtabs, dump_last_symtab,
dump_blockvector, dump_block, dump_addrchass, dump_namespace,
dump_symbol, dump_type, dump_linetable, dump_strtbl):  Remove, unused.
* xcoffread.c (dump_symtab_lines, dump_symtabs, dump_last_symtab,
dump_blockvector, dump_block, dump_addrchass, dump_namespace,
dump_symbol, dump_type, dump_linetable, dump_strtbl):  Remove 2nd
unused copy!

* buildsym.c (define_symbol):  Handle global register variables
(from Pierre Willard).  Complain if register numbers are too large.

Fred Fish bf349b77fa Add OBJF_SYMS flag and use it to decide whether or not we have already
tried to read symbols from a file, for mapped objfiles.  This fixes a
memory leak (actually a constant memory growth) due to reading symbol
files with no debug info and thus generating no psymtabs or symtabs.
Most typically happened with shared libraries.

Fred Fish 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.
