[binutils.git] / gdb / ChangeLog

Thu Apr  3 15:10:30 1997  Michael Snyder  <[email protected]>

        * 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.

Thu Apr  3 10:31:12 1997  Mark Alexander  <[email protected]>

        * config/mips/tm-mips.h (mips_in_call_stub, mips_in_return_stub,

        (IN_SOLIB_CALL_TRAMPOLINE, IN_SOLIB_RETURN_TRAMPOLINE,

        the above functions.
        (INIT_FRAME_PC_FIRST): Change to invoke mips_init_frame_pc.
        (mips_init_frame_pc): Declare.
        * infrun.c (wait_for_inferior): Use new IGNORE_HELPER_CALL macro

        current address for repeated commands.
        * sparc-nat.c (fetch_inferior_registers):  Change
        target_xfer_memory to target_{read write}_memory to allow changes
        to target_xfer_memory interface for section info.
        * symmisc.c (dump_msymbols print_symbol):  Print section
        assocaited with symbol.
        * symtab.c (fixup_symbol_section):  New routine to
        add section info to symbols returned by lookup_symbol.
        * symtab.h (struct general_symbol_info):  Add bfd section to
        symbols.
        * target.c target.h (target_xfer_memory):  Add bfd section to
        args.
        * (target_read_memory_section):  New routine to read data from a
        specific section.
        * (target_memory_bfd_section):  New global variable to pass bfd
        section in to targets.
        * valarith.c (value_add value_addr value_array):  Preserve bfd
        section when computing new value.
        * value.h (struct value):  Add bfd section to values.
        * values.c (allocate_value value_copy):  Initialize/preserve bfd
        section.
        * (unpack_double):  Clean up _MSC_VER conditionals to remove

        * v850ice.c:  New module to support communication with NEC's
        PC-based ICE.
        * config/v850/tm-v850.h (REGISTER_NAMES):  Replace sp, gp, fp, and

        * mn10300-tdep.c (mn10300_push_arguments): rewrote,

        * config/mn10300/tm-mn10300.h: ripped out RP_REGNUM, V0_REGNUM,
        ARG0_REGNUM, ARGLAST_REGNUM (all not appropriate for mn10300
