 478         the obvious.
 479         * remote-e7000.c:  Remove debugify stuff.  Change printf, fprintf
 480         to _filtered forms to make output appear in GUIs.  Replace all
 481         uses of SERIAL_READCHAR with readchar, which has better error

 489         necessary.
 490         (e7000_open):  Split into two pieces.  Second part is

 499         * ser-e7kpc.c: Get rid of the DLL's since we can access the device
 500         directly from Win32s and Win95.  Get rid of debugify crud.

 594 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
 595
 596         * procfs.c: Substantial (but incomplete) changes to support
 597         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
 598         struct now has substructs like struct flt_ctl instead of
 599         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 600         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 601         still have the structs and multiple fds, but don't use the
 602         entire struct and the four fds all point to the same thing.
 603         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 604         procfs with reads/writes or use ioctl instead.  We use
 605         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 606         multiple fds or not.  PROC_NAME_FMT is split out into
 607         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 608         STATUS_PROC_NAME_FMT.
 609
 610         (procfs_notice_signals): now a necessary wrapper around
 611         (notice_signals): which are the new guts for noticing signals
 612         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 613         determine whether or not to attempt to open the ctl_fd.
 614         (procfs_read_status): new local function, reads procfs status
 615         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 616         (procfs_write_pckill): new local function, writes a PCKILL
 617         (unconditionally_kill_inferior): remove signo since we now
 618         just call procfs_write_pckill().
 619         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 620         (proc_iterate_over_mappings): the whole function is ifdefed
 621         on UNIXWARE to keep things readable.
 622
 623         Expanded the syscall_table to include new potential sysv4.2mp
 624         members.  Note that all ifdefs of UNIXWARE should be eliminated
 625         if possible or renamed to describe what's being selected for a
 626         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 627         IRIX specific code now also checks it's not UNIXWARE.
 628
 629         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
 630         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
 631         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
 632         "/debug/%d" as PROC_NAME_FMT used to be

 644         lousy out-of-date clone of remote.c.

 665         for hosts which default to unsigned chars (such as SGI's).

 671         * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
 672         find_pc_sect_function(), find_pc_sect_partial_function(): new
 673         functions for debugging overlays; pc without section is ambiguous.
 674         * breakpoint.[ch]: add section pointer to breakpoint struct;
 675         add section argument to check_duplicates(); check section as well
 676         as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
 677         breakpoint_thread_match(), bpstat_stop_status()];
 678         add section argument to describe_other_breakpoints();
 679         use INIT_SAL() macro to zero-out new sal structures;
 680         make resolve_sal_pc() fix up the sal's section as well as its pc;
 681         match on section + pc in clear_command() and delete_breakpoint();
 682         account for overlay sections in insert_breakpoints(),
 683         remove_breakpoint() and breakpoint_re_set_one();
 684         all this to support overlays where a PC is not unique.
 685         * exec.c: change xfer_memory() to handle overlay sections.
 686         * findvar.c: change read_var_value() to handle overlay sections.
 687         * frame.h: declaration for block_for_pc_sect() [blockframe.c].
 688         * infcmd.c: jump_command() warns against jumping into an overlay
 689         that's not in memory.  Also use INIT_SAL() to initialize sals.
 690         * infrun.c: wait_for_inferior() sets a flag to invalidate cached
 691         overlay state information; Also use INIT_SAL() to init sals.
 692         * m32r-rom.c: modify load routines to use LMA instead of VMA.
 693         * m32r-stub.c: mask exit value down to 8 bits; screen out any
 694         memory read/writes in the range 600000 to a00000, and ff680000
 695         to ff800000 (hangs because nothing is mapped there); fix strcpy().
 696         * maint.c: maintenance command "translate-address" supports overlays.
 697         * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
 698         * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
 699         this constitutes gdb's internal overlay mapping table.  Add macro
 700         ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
 701         Add function find_pc_sect_section().
 702         * printcmd.c: modify print_address_symbolic() with overlay smarts;
 703         modify address_info() with overlay smarts; add function sym_info()
 704         to support the INFO SYMBOL command (translate address to symbol(s));
 705         modify disassemble_command() to work on unmapped overlays.
 706         * source.c: use INIT_SAL() to initialize sals.
 707         * symfile.[ch]: change generic_load() to use section's LMA address
 708         instead of VMA address, for overlay sections.
 709         Add numerous functions for finding a PC's section / overlay,
 710         translating between VMA and LMA address ranges, determining if an
 711         overlay section is mapped, etc.  Add several user commands for
 712         overlay debugging.  Add support for a "generic" form of automatically
 713         reading overlay mapping info from the inferior (based on the default
 714         (simple) overlay manager which Cygnus provides as an example).
 715         * symtab.[ch]: add functions find_pc_sect_symtab(),
 716         find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
 717         for lookup; modify lookup_symbol and decode_line_1() to use them;
 718         modify find_function_start_sal() to account for overlay sections;
 719         add macro INIT_SAL() for initializing struct symtab_and_line.
 720         * target.c: fix a comment in the declaration of target_ops.
