995 * procfs.c: Substantial (but incomplete) changes to support
996 sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
997 struct now has substructs like struct flt_ctl instead of
998 just a fltset_t and has a ctl_fd, status_fd, as_fd, and
999 map_fd instead of a single fd. Non-sysv4.2mp procfs models
1000 still have the structs and multiple fds, but don't use the
1001 entire struct and the four fds all point to the same thing.
1002 We use PROCFS_USE_READ_WRITE to decide whether to talk to
1003 procfs with reads/writes or use ioctl instead. We use
1004 HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
1005 multiple fds or not. PROC_NAME_FMT is split out into
1006 CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
1007 STATUS_PROC_NAME_FMT.
1009 (procfs_notice_signals): now a necessary wrapper around
1010 (notice_signals): which are the new guts for noticing signals
1011 (open_proc_file): gets a new flag arg used in sysv4.2mp to
1012 determine whether or not to attempt to open the ctl_fd.
1013 (procfs_read_status): new local function, reads procfs status
1014 (procfs_write_pcwstop): new local function, writes a PCWSTOP
1015 (procfs_write_pckill): new local function, writes a PCKILL
1016 (unconditionally_kill_inferior): remove signo since we now
1017 just call procfs_write_pckill().
1018 (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
1019 (proc_iterate_over_mappings): the whole function is ifdefed
1020 on UNIXWARE to keep things readable.
1022 Expanded the syscall_table to include new potential sysv4.2mp
1023 members. Note that all ifdefs of UNIXWARE should be eliminated
1024 if possible or renamed to describe what's being selected for a
1025 bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
1026 IRIX specific code now also checks it's not UNIXWARE.
1028 * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
1029 HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE

1031 "/debug/%d" as PROC_NAME_FMT used to be

1041 * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
1042 remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
1043 lousy out-of-date clone of remote.c.
1045 Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
1047 * remote.c: Fix problems realized while showering.
1048 * (hexnumlen): Add prototype. Use max, not min.
1049 * (remote_write_bytes remote_read_bytes): Fix max packet size
1050 calculations to properly account for packet overhead. Also handle
1051 (probably rare) case where remote_register_buf_size isn't set.
1053 * remote.c: Fix doc for `C' and `S' commands to indicate full
1055 * (remote_ops extended_remote_ops remote_desc remote_write_size):

1059 limit size of memory read and write commands.

1061 another target switch to the remote target.
1062 * target.h: Add prototype for push_remote_target.
1063 * sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
1064 for hosts which default to unsigned chars (such as SGI's).
1065 * (_initialize_sh_tdep): Don't set remote_write_size. It's now
1066 handled automatically in remote.c.
1068 Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
1070 * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
1071 find_pc_sect_function(), find_pc_sect_partial_function(): new
1072 functions for debugging overlays; pc without section is ambiguous.
1073 * breakpoint.[ch]: add section pointer to breakpoint struct;
1074 add section argument to check_duplicates(); check section as well
1075 as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
1076 breakpoint_thread_match(), bpstat_stop_status()];
1077 add section argument to describe_other_breakpoints();
1078 use INIT_SAL() macro to zero-out new sal structures;
1079 make resolve_sal_pc() fix up the sal's section as well as its pc;
1080 match on section + pc in clear_command() and delete_breakpoint();

1085 * findvar.c: change read_var_value() to handle overlay sections.
1086 * frame.h: declaration for block_for_pc_sect() [blockframe.c].
1087 * infcmd.c: jump_command() warns against jumping into an overlay
1088 that's not in memory. Also use INIT_SAL() to initialize sals.
1089 * infrun.c: wait_for_inferior() sets a flag to invalidate cached
1090 overlay state information; Also use INIT_SAL() to init sals.
1091 * m32r-rom.c: modify load routines to use LMA instead of VMA.
1092 * m32r-stub.c: mask exit value down to 8 bits; screen out any
1093 memory read/writes in the range 600000 to a00000, and ff680000
1094 to ff800000 (hangs because nothing is mapped there); fix strcpy().
1095 * maint.c: maintenance command "translate-address" supports overlays.
1096 * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
1097 * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
1098 this constitutes gdb's internal overlay mapping table. Add macro
1099 ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
1100 Add function find_pc_sect_section().
1101 * printcmd.c: modify print_address_symbolic() with overlay smarts;
1102 modify address_info() with overlay smarts; add function sym_info()
1103 to support the INFO SYMBOL command (translate address to symbol(s));
1104 modify disassemble_command() to work on unmapped overlays.
1105 * source.c: use INIT_SAL() to initialize sals.
1106 * symfile.[ch]: change generic_load() to use section's LMA address
1107 instead of VMA address, for overlay sections.
1108 Add numerous functions for finding a PC's section / overlay,
1109 translating between VMA and LMA address ranges, determining if an
1110 overlay section is mapped, etc. Add several user commands for
1111 overlay debugging. Add support for a "generic" form of automatically
1112 reading overlay mapping info from the inferior (based on the default
1113 (simple) overlay manager which Cygnus provides as an example).
1114 * symtab.[ch]: add functions find_pc_sect_symtab(),
1115 find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
1116 for lookup; modify lookup_symbol and decode_line_1() to use them;
1117 modify find_function_start_sal() to account for overlay sections;
1118 add macro INIT_SAL() for initializing struct symtab_and_line.
1119 * target.c: fix a comment in the declaration of target_ops.
1121 Thu Apr 3 10:31:12 1997 Mark Alexander <marka@cygnus.com>

1134 the above functions.
1135 (INIT_FRAME_PC_FIRST): Change to invoke mips_init_frame_pc.
1136 (mips_init_frame_pc): Declare.
1137 * infrun.c (wait_for_inferior): Use new IGNORE_HELPER_CALL macro
1138 to decide if certain library function calls should be ignored.

1264 on little-endian hosts.
1266 * mdebugread.c (parse_procedure): Adjust address of procedure relative

1268 strings that may precede functions in the text section. Remove
1269 now-useless lowest_pdr_addr from argument list and all calls.
1271 Fri Mar 21 15:36:25 1997 Michael Meissner <meissner@cygnus.com>
