478 * procfs.c: Substantial (but incomplete) changes to support
479 sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
480 struct now has substructs like struct flt_ctl instead of
481 just a fltset_t and has a ctl_fd, status_fd, as_fd, and
482 map_fd instead of a single fd. Non-sysv4.2mp procfs models
483 still have the structs and multiple fds, but don't use the
484 entire struct and the four fds all point to the same thing.
485 We use PROCFS_USE_READ_WRITE to decide whether to talk to
486 procfs with reads/writes or use ioctl instead. We use
487 HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
488 multiple fds or not. PROC_NAME_FMT is split out into
489 CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
490 STATUS_PROC_NAME_FMT.
492 (procfs_notice_signals): now a necessary wrapper around
493 (notice_signals): which are the new guts for noticing signals
494 (open_proc_file): gets a new flag arg used in sysv4.2mp to
495 determine whether or not to attempt to open the ctl_fd.
496 (procfs_read_status): new local function, reads procfs status
497 (procfs_write_pcwstop): new local function, writes a PCWSTOP
498 (procfs_write_pckill): new local function, writes a PCKILL
499 (unconditionally_kill_inferior): remove signo since we now
500 just call procfs_write_pckill().
501 (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
502 (proc_iterate_over_mappings): the whole function is ifdefed
503 on UNIXWARE to keep things readable.
505 Expanded the syscall_table to include new potential sysv4.2mp
506 members. Note that all ifdefs of UNIXWARE should be eliminated
507 if possible or renamed to describe what's being selected for a
508 bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
509 IRIX specific code now also checks it's not UNIXWARE.
511 * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
512 HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE

524 * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
525 remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
526 lousy out-of-date clone of remote.c.
528 Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
530 * remote.c: Fix problems realized while showering.
531 * (hexnumlen): Add prototype. Use max, not min.
532 * (remote_write_bytes remote_read_bytes): Fix max packet size

538 * (remote_ops extended_remote_ops remote_desc remote_write_size):

541 Record size of response to fetch registers command, use this to
542 limit size of memory read and write commands.

547 for hosts which default to unsigned chars (such as SGI's).
548 * (_initialize_sh_tdep): Don't set remote_write_size. It's now
549 handled automatically in remote.c.

553 * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
554 find_pc_sect_function(), find_pc_sect_partial_function(): new
555 functions for debugging overlays; pc without section is ambiguous.
556 * breakpoint.[ch]: add section pointer to breakpoint struct;
557 add section argument to check_duplicates(); check section as well
558 as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
559 breakpoint_thread_match(), bpstat_stop_status()];
560 add section argument to describe_other_breakpoints();
561 use INIT_SAL() macro to zero-out new sal structures;
562 make resolve_sal_pc() fix up the sal's section as well as its pc;
563 match on section + pc in clear_command() and delete_breakpoint();
564 account for overlay sections in insert_breakpoints(),
565 remove_breakpoint() and breakpoint_re_set_one();
566 all this to support overlays where a PC is not unique.

571 that's not in memory. Also use INIT_SAL() to initialize sals.
572 * infrun.c: wait_for_inferior() sets a flag to invalidate cached
573 overlay state information; Also use INIT_SAL() to init sals.
574 * m32r-rom.c: modify load routines to use LMA instead of VMA.
575 * m32r-stub.c: mask exit value down to 8 bits; screen out any
576 memory read/writes in the range 600000 to a00000, and ff680000
577 to ff800000 (hangs because nothing is mapped there); fix strcpy().
578 * maint.c: maintenance command "translate-address" supports overlays.
579 * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
580 * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
581 this constitutes gdb's internal overlay mapping table. Add macro
582 ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
583 Add function find_pc_sect_section().
584 * printcmd.c: modify print_address_symbolic() with overlay smarts;
585 modify address_info() with overlay smarts; add function sym_info()
586 to support the INFO SYMBOL command (translate address to symbol(s));

588 * source.c: use INIT_SAL() to initialize sals.
589 * symfile.[ch]: change generic_load() to use section's LMA address
590 instead of VMA address, for overlay sections.
591 Add numerous functions for finding a PC's section / overlay,
592 translating between VMA and LMA address ranges, determining if an
593 overlay section is mapped, etc. Add several user commands for
594 overlay debugging. Add support for a "generic" form of automatically
595 reading overlay mapping info from the inferior (based on the default
596 (simple) overlay manager which Cygnus provides as an example).
597 * symtab.[ch]: add functions find_pc_sect_symtab(),
598 find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
599 for lookup; modify lookup_symbol and decode_line_1() to use them;
600 modify find_function_start_sal() to account for overlay sections;
601 add macro INIT_SAL() for initializing struct symtab_and_line.
602 * target.c: fix a comment in the declaration of target_ops.

608 with MIPS16 call/return thunks.

667 to va_list from void *, since va_list might not be a pointer
671 Fri Mar 28 17:04:02 1997 Jason Molenda (crash@godzilla.cygnus.co.jp)
673 * Makefile.in (gdbtk.o): look for GDBTK_LIBRARY in $(datadir) by
