  49 Mon Apr 14 11:55:27 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
  50
  51         * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
  52         since gcc automatically includes it
  53
  54 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
  55
  56         * procfs.c: Substantial (but incomplete) changes to support
  57         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
  58         struct now has substructs like struct flt_ctl instead of
  59         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
  60         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
  61         still have the structs and multiple fds, but don't use the
  62         entire struct and the four fds all point to the same thing.
  63         We use PROCFS_USE_READ_WRITE to decide whether to talk to
  64         procfs with reads/writes or use ioctl instead.  We use
  65         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
  66         multiple fds or not.  PROC_NAME_FMT is split out into
  67         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
  68         STATUS_PROC_NAME_FMT.
  69
  70         (procfs_notice_signals): now a necessary wrapper around
  71         (notice_signals): which are the new guts for noticing signals
  72         (open_proc_file): gets a new flag arg used in sysv4.2mp to
  73         determine whether or not to attempt to open the ctl_fd.
  74         (procfs_read_status): new local function, reads procfs status
  75         (procfs_write_pcwstop): new local function, writes a PCWSTOP
  76         (procfs_write_pckill): new local function, writes a PCKILL
  77         (unconditionally_kill_inferior): remove signo since we now
  78         just call procfs_write_pckill().
  79         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
  80         (proc_iterate_over_mappings): the whole function is ifdefed
  81         on UNIXWARE to keep things readable.
  82
  83         Expanded the syscall_table to include new potential sysv4.2mp
  84         members.  Note that all ifdefs of UNIXWARE should be eliminated
  85         if possible or renamed to describe what's being selected for a
  86         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
  87         IRIX specific code now also checks it's not UNIXWARE.
  88
  89         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
  90         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
  91         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
  92         "/debug/%d" as PROC_NAME_FMT used to be
  93
  94 Wed Apr  9 11:36:14 1997  Jeffrey A Law  (law@cygnus.com)
  95
  96         * mn10300-tdep.c: Almost completely rewritten based on mn10200
  97         port.
  98         * config/mn10300/tm-mn10300.h: Likewise.
  99
 100 Tue Apr  8 10:45:24 1997  Stu Grossman  (grossman@critters.cygnus.com)
 101
 102         * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
 103         remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
 104         lousy out-of-date clone of remote.c.
 105
 106 Fri Apr  4 08:21:21 1997  Stu Grossman  (grossman@critters.cygnus.com)
 107
 108         * remote.c:  Fix problems realized while showering.
 109         * (hexnumlen):  Add prototype.  Use max, not min.
 110         * (remote_write_bytes remote_read_bytes):  Fix max packet size
 111         calculations to properly account for packet overhead.  Also handle
 112         (probably rare) case where remote_register_buf_size isn't set.
 113
 114         * remote.c:  Fix doc for `C' and `S' commands to indicate full
 115         address.
 116         * (remote_ops extended_remote_ops remote_desc remote_write_size):
 117         Make static.
 118         * (remote_fetch_registers remote_write_bytes remote_read_bytes):
 119         Record size of response to fetch registers command, use this to
 120         limit size of memory read and write commands.
 121         * (push_remote_target):  New function to make it possible to have
 122         another target switch to the remote target.
 123         * target.h:  Add prototype for push_remote_target.
 124         * sh-tdep.c (sh_frame_find_saved_regs):  Fix sign extension bugs
 125         for hosts which default to unsigned chars (such as SGI's).
 126         * (_initialize_sh_tdep):  Don't set remote_write_size.  It's now
 127         handled automatically in remote.c.
 128
 129 Thu Apr  3 15:10:30 1997  Michael Snyder  <msnyder@cleaver.cygnus.com>
 130
 131         * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
 132         find_pc_sect_function(), find_pc_sect_partial_function(): new
 133         functions for debugging overlays; pc without section is ambiguous.
 134         * breakpoint.[ch]: add section pointer to breakpoint struct;
 135         add section argument to check_duplicates(); check section as well
 136         as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
 137         breakpoint_thread_match(), bpstat_stop_status()];
 138         add section argument to describe_other_breakpoints();
 139         use INIT_SAL() macro to zero-out new sal structures;
 140         make resolve_sal_pc() fix up the sal's section as well as its pc;
 141         match on section + pc in clear_command() and delete_breakpoint();
 142         account for overlay sections in insert_breakpoints(),
 143         remove_breakpoint() and breakpoint_re_set_one();
 144         all this to support overlays where a PC is not unique.
 145         * exec.c: change xfer_memory() to handle overlay sections.
 146         * findvar.c: change read_var_value() to handle overlay sections.
 147         * frame.h: declaration for block_for_pc_sect() [blockframe.c].
 148         * infcmd.c: jump_command() warns against jumping into an overlay
 149         that's not in memory.  Also use INIT_SAL() to initialize sals.
 150         * infrun.c: wait_for_inferior() sets a flag to invalidate cached
 151         overlay state information; Also use INIT_SAL() to init sals.
 152         * m32r-rom.c: modify load routines to use LMA instead of VMA.
 153         * m32r-stub.c: mask exit value down to 8 bits; screen out any
 154         memory read/writes in the range 600000 to a00000, and ff680000
 155         to ff800000 (hangs because nothing is mapped there); fix strcpy().
 156         * maint.c: maintenance command "translate-address" supports overlays.
 157         * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
 158         * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
 159         this constitutes gdb's internal overlay mapping table.  Add macro
 160         ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
 161         Add function find_pc_sect_section().
 162         * printcmd.c: modify print_address_symbolic() with overlay smarts;
 163         modify address_info() with overlay smarts; add function sym_info()
 164         to support the INFO SYMBOL command (translate address to symbol(s));
 165         modify disassemble_command() to work on unmapped overlays.
 166         * source.c: use INIT_SAL() to initialize sals.
 167         * symfile.[ch]: change generic_load() to use section's LMA address
 168         instead of VMA address, for overlay sections.
 169         Add numerous functions for finding a PC's section / overlay,
 170         translating between VMA and LMA address ranges, determining if an
 171         overlay section is mapped, etc.  Add several user commands for
 172         overlay debugging.  Add support for a "generic" form of automatically
 173         reading overlay mapping info from the inferior (based on the default
 174         (simple) overlay manager which Cygnus provides as an example).
 175         * symtab.[ch]: add functions find_pc_sect_symtab(),
 176         find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
 177         for lookup; modify lookup_symbol and decode_line_1() to use them;
 178         modify find_function_start_sal() to account for overlay sections;
 179         add macro INIT_SAL() for initializing struct symtab_and_line.
 180         * target.c: fix a comment in the declaration of target_ops.
 181

 186         with MIPS16 call/return thunks.
 187         (mips_init_frame_pc_first): New function to implement
 188         INIT_FRAME_PC_FIRST macro; includes code from old macro plus
 189         new code to skip over MIPS16 thunks.
 190         (mips_frame_chain): Skip over MIPS16 thunks.
 191         * config/mips/tm-mips.h (mips_in_call_stub, mips_in_return_stub,
 192         mips_skip_stub, mips_ignore_helper): Declare.
 193         (IN_SOLIB_CALL_TRAMPOLINE, IN_SOLIB_RETURN_TRAMPOLINE,
 194         SKIP_TRAMPOLINE_CODE, IGNORE_HELPER_CALL): New macros that invoke
 195         the above functions.
 196         (INIT_FRAME_PC_FIRST): Change to invoke mips_init_frame_pc.
 197         (mips_init_frame_pc): Declare.
 198         * infrun.c (wait_for_inferior): Use new IGNORE_HELPER_CALL macro
 199         to decide if certain library function calls should be ignored.

 272
 273         * symtab.c (find_pc_symtab): change to support the case
 274         where the objfile is reordered and contains both coff and
 275         stabs debugging info (continue on if a psymtab isn't found).
 276

 278
 279         Fixes from Peter Schauer:

 281         REGISTER_CONVERT_FROM_TYPE): Swap words if target, not host,
 282         is big-endian and if registers are 32 bits.
