 703
 704 Mon Apr 14 16:25:10 1997  Ian Lance Taylor  <ian@cygnus.com>
 705

 708
 709 Mon Apr 14 11:55:27 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
 710
 711         * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
 712         since gcc automatically includes it
 713
 714 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
 715
 716         * procfs.c: Substantial (but incomplete) changes to support
 717         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
 718         struct now has substructs like struct flt_ctl instead of
 719         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 720         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 721         still have the structs and multiple fds, but don't use the
 722         entire struct and the four fds all point to the same thing.
 723         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 724         procfs with reads/writes or use ioctl instead.  We use
 725         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 726         multiple fds or not.  PROC_NAME_FMT is split out into
 727         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 728         STATUS_PROC_NAME_FMT.
 729
 730         (procfs_notice_signals): now a necessary wrapper around
 731         (notice_signals): which are the new guts for noticing signals
 732         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 733         determine whether or not to attempt to open the ctl_fd.
 734         (procfs_read_status): new local function, reads procfs status
 735         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 736         (procfs_write_pckill): new local function, writes a PCKILL
 737         (unconditionally_kill_inferior): remove signo since we now
 738         just call procfs_write_pckill().
 739         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 740         (proc_iterate_over_mappings): the whole function is ifdefed
 741         on UNIXWARE to keep things readable.
 742
 743         Expanded the syscall_table to include new potential sysv4.2mp
 744         members.  Note that all ifdefs of UNIXWARE should be eliminated
 745         if possible or renamed to describe what's being selected for a
 746         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 747         IRIX specific code now also checks it's not UNIXWARE.
 748
 749         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
 750         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
 751         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
 752         "/debug/%d" as PROC_NAME_FMT used to be
 753
 754 Wed Apr  9 11:36:14 1997  Jeffrey A Law  (law@cygnus.com)
 755
 756         * mn10300-tdep.c: Almost completely rewritten based on mn10200
 757         port.
 758         * config/mn10300/tm-mn10300.h: Likewise.
 759
 760 Tue Apr  8 10:45:24 1997  Stu Grossman  (grossman@critters.cygnus.com)
 761
 762         * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
 763         remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
 764         lousy out-of-date clone of remote.c.
 765
 766 Fri Apr  4 08:21:21 1997  Stu Grossman  (grossman@critters.cygnus.com)
 767
 768         * remote.c:  Fix problems realized while showering.
 769         * (hexnumlen):  Add prototype.  Use max, not min.
 770         * (remote_write_bytes remote_read_bytes):  Fix max packet size
 771         calculations to properly account for packet overhead.  Also handle
 772         (probably rare) case where remote_register_buf_size isn't set.
 773
 774         * remote.c:  Fix doc for `C' and `S' commands to indicate full
 775         address.
 776         * (remote_ops extended_remote_ops remote_desc remote_write_size):
 777         Make static.
 778         * (remote_fetch_registers remote_write_bytes remote_read_bytes):
 779         Record size of response to fetch registers command, use this to
 780         limit size of memory read and write commands.
 781         * (push_remote_target):  New function to make it possible to have
 782         another target switch to the remote target.
 783         * target.h:  Add prototype for push_remote_target.
 784         * sh-tdep.c (sh_frame_find_saved_regs):  Fix sign extension bugs
 785         for hosts which default to unsigned chars (such as SGI's).
 786         * (_initialize_sh_tdep):  Don't set remote_write_size.  It's now
 787         handled automatically in remote.c.
 788
 789 Thu Apr  3 15:10:30 1997  Michael Snyder  <msnyder@cleaver.cygnus.com>
 790
 791         * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
 792         find_pc_sect_function(), find_pc_sect_partial_function(): new
 793         functions for debugging overlays; pc without section is ambiguous.
 794         * breakpoint.[ch]: add section pointer to breakpoint struct;
 795         add section argument to check_duplicates(); check section as well
 796         as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
 797         breakpoint_thread_match(), bpstat_stop_status()];
 798         add section argument to describe_other_breakpoints();
 799         use INIT_SAL() macro to zero-out new sal structures;
 800         make resolve_sal_pc() fix up the sal's section as well as its pc;
 801         match on section + pc in clear_command() and delete_breakpoint();
 802         account for overlay sections in insert_breakpoints(),
 803         remove_breakpoint() and breakpoint_re_set_one();
 804         all this to support overlays where a PC is not unique.
 805         * exec.c: change xfer_memory() to handle overlay sections.
 806         * findvar.c: change read_var_value() to handle overlay sections.
 807         * frame.h: declaration for block_for_pc_sect() [blockframe.c].
 808         * infcmd.c: jump_command() warns against jumping into an overlay
 809         that's not in memory.  Also use INIT_SAL() to initialize sals.
 810         * infrun.c: wait_for_inferior() sets a flag to invalidate cached
 811         overlay state information; Also use INIT_SAL() to init sals.
 812         * m32r-rom.c: modify load routines to use LMA instead of VMA.
 813         * m32r-stub.c: mask exit value down to 8 bits; screen out any
 814         memory read/writes in the range 600000 to a00000, and ff680000
 815         to ff800000 (hangs because nothing is mapped there); fix strcpy().
 816         * maint.c: maintenance command "translate-address" supports overlays.
 817         * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
 818         * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
 819         this constitutes gdb's internal overlay mapping table.  Add macro
 820         ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
 821         Add function find_pc_sect_section().
 822         * printcmd.c: modify print_address_symbolic() with overlay smarts;
 823         modify address_info() with overlay smarts; add function sym_info()
 824         to support the INFO SYMBOL command (translate address to symbol(s));
 825         modify disassemble_command() to work on unmapped overlays.
 826         * source.c: use INIT_SAL() to initialize sals.
 827         * symfile.[ch]: change generic_load() to use section's LMA address
 828         instead of VMA address, for overlay sections.
 829         Add numerous functions for finding a PC's section / overlay,
 830         translating between VMA and LMA address ranges, determining if an
 831         overlay section is mapped, etc.  Add several user commands for
 832         overlay debugging.  Add support for a "generic" form of automatically
 833         reading overlay mapping info from the inferior (based on the default
 834         (simple) overlay manager which Cygnus provides as an example).
 835         * symtab.[ch]: add functions find_pc_sect_symtab(),
 836         find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
 837         for lookup; modify lookup_symbol and decode_line_1() to use them;
 838         modify find_function_start_sal() to account for overlay sections;
 839         add macro INIT_SAL() for initializing struct symtab_and_line.
 840         * target.c: fix a comment in the declaration of target_ops.

 850         (mips_frame_chain): Skip over MIPS16 thunks.
 851         * config/mips/tm-mips.h (mips_in_call_stub, mips_in_return_stub,

1642         unnecessary cast for assignment of struct dbx_symfile_info.
1643         Struct objfile now uses a real pointer instead of PTR for this
1644         element.
1645         * dbxread.c (dbx_symfile_init): Stash bfd section pointers for
1646         text, data and bss into dbx_symfile_info.

1651         * gdb-stabs.h:  Add section pointers for text, data and bss
1652         sections.
1653         * maint.c (translate address command):  Add test code for overlay
1654         address translation.
1655         * printcmd.c (do_examine do_one_display):  Now takes a bfd section
1656         arg.
1657         * (print_formatted x_command):  Record current section along with
1658         current address for repeated commands.
1659         * sparc-nat.c (fetch_inferior_registers):  Change
1660         target_xfer_memory to target_{read write}_memory to allow changes
1661         to target_xfer_memory interface for section info.
1662         * symmisc.c (dump_msymbols print_symbol):  Print section
1663         assocaited with symbol.
1664         * symtab.c (fixup_symbol_section):  New routine to
1665         add section info to symbols returned by lookup_symbol.
1666         * symtab.h (struct general_symbol_info):  Add bfd section to
1667         symbols.
1668         * target.c target.h (target_xfer_memory):  Add bfd section to
1669         args.
1670         * (target_read_memory_section):  New routine to read data from a
1671         specific section.
1672         * (target_memory_bfd_section):  New global variable to pass bfd
1673         section in to targets.
1674         * valarith.c (value_add value_addr value_array):  Preserve bfd
1675         section when computing new value.
1676         * value.h (struct value):  Add bfd section to values.
1677         * values.c (allocate_value value_copy):  Initialize/preserve bfd
1678         section.
1679         * (unpack_double):  Clean up _MSC_VER conditionals to remove
1680         duplicate code.
1681 start-sanitize-v850
1682         * v850ice.c:  New module to support communication with NEC's
1683         PC-based ICE.
1684         * config/v850/tm-v850.h (REGISTER_NAMES):  Replace sp, gp, fp, and
1685         ep names with rxx names.  sp and fp are renamed via a different
1686         mechanism.

1691         * mn10300-tdep.c (mn10300_push_arguments): rewrote,
1692         also removed code elsewhere that made use of RP_REGNUM.
1693         * config/mn10300/tm-mn10300.h: ripped out RP_REGNUM, V0_REGNUM,
1694         ARG0_REGNUM, ARGLAST_REGNUM (all not appropriate for mn10300
1695         arch.), redefined SAVED_PC_AFTER_CALL, EXTRACT_RETURN_VALUE,
1696         EXTRACT_STRUCT_VALUE_ADDRESS, STORE_RETURN_VALUE.
