   6
   7 Tue Apr 15 15:31:09 1997  Stan Shebs  <shebs@andros.cygnus.com>
   8
   9         * remote.c (get_offsets): Don't use scanf for interpreting
  10         response to qOffsets.
  11
  12 Tue Apr 15 14:51:04 1997  Ian Lance Taylor  <ian@cygnus.com>

  15         (INSTALL_XFORM1): Remove.
  16         (install-only): Use $(program_transform_name) directly, rather
  17         than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).
  18         (uninstall): Transform name.
  19
  20 Mon Apr 14 17:06:27 1997  Mark Alexander  <marka@cygnus.com>
  21
  22         * remote-mips.c (mips_load): Ensure that PC gets updated
  23         after a load on LSI target.
  24
  25 Mon Apr 14 15:54:51 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
  26
  27         * procfs.c (notice_signals): fix typo

  30
  31         * gdbserver/Makefile.in (INSTALL): Change install.sh to
  32         install-sh.
  33
  34 Mon Apr 14 11:55:27 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
  35
  36         * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
  37         since gcc automatically includes it
  38
  39 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
  40
  41         * procfs.c: Substantial (but incomplete) changes to support
  42         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
  43         struct now has substructs like struct flt_ctl instead of
  44         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
  45         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
  46         still have the structs and multiple fds, but don't use the
  47         entire struct and the four fds all point to the same thing.
  48         We use PROCFS_USE_READ_WRITE to decide whether to talk to
  49         procfs with reads/writes or use ioctl instead.  We use
  50         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
  51         multiple fds or not.  PROC_NAME_FMT is split out into
  52         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
  53         STATUS_PROC_NAME_FMT.
  54
  55         (procfs_notice_signals): now a necessary wrapper around
  56         (notice_signals): which are the new guts for noticing signals
  57         (open_proc_file): gets a new flag arg used in sysv4.2mp to
  58         determine whether or not to attempt to open the ctl_fd.
  59         (procfs_read_status): new local function, reads procfs status
  60         (procfs_write_pcwstop): new local function, writes a PCWSTOP
  61         (procfs_write_pckill): new local function, writes a PCKILL
  62         (unconditionally_kill_inferior): remove signo since we now
  63         just call procfs_write_pckill().
  64         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
  65         (proc_iterate_over_mappings): the whole function is ifdefed
  66         on UNIXWARE to keep things readable.
  67
  68         Expanded the syscall_table to include new potential sysv4.2mp
  69         members.  Note that all ifdefs of UNIXWARE should be eliminated
  70         if possible or renamed to describe what's being selected for a
  71         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
  72         IRIX specific code now also checks it's not UNIXWARE.
  73
  74         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
  75         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
  76         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
  77         "/debug/%d" as PROC_NAME_FMT used to be
  78
  79 Wed Apr  9 11:36:14 1997  Jeffrey A Law  (law@cygnus.com)
  80
  81         * mn10300-tdep.c: Almost completely rewritten based on mn10200
  82         port.
  83         * config/mn10300/tm-mn10300.h: Likewise.
  84
  85 Tue Apr  8 10:45:24 1997  Stu Grossman  (grossman@critters.cygnus.com)
  86
  87         * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
  88         remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
  89         lousy out-of-date clone of remote.c.
  90
  91 Fri Apr  4 08:21:21 1997  Stu Grossman  (grossman@critters.cygnus.com)
  92
  93         * remote.c:  Fix problems realized while showering.
  94         * (hexnumlen):  Add prototype.  Use max, not min.
  95         * (remote_write_bytes remote_read_bytes):  Fix max packet size
  96         calculations to properly account for packet overhead.  Also handle
  97         (probably rare) case where remote_register_buf_size isn't set.
  98
  99         * remote.c:  Fix doc for `C' and `S' commands to indicate full
 100         address.
 101         * (remote_ops extended_remote_ops remote_desc remote_write_size):
 102         Make static.
 103         * (remote_fetch_registers remote_write_bytes remote_read_bytes):
 104         Record size of response to fetch registers command, use this to
 105         limit size of memory read and write commands.
 106         * (push_remote_target):  New function to make it possible to have
 107         another target switch to the remote target.
 108         * target.h:  Add prototype for push_remote_target.
 109         * sh-tdep.c (sh_frame_find_saved_regs):  Fix sign extension bugs
 110         for hosts which default to unsigned chars (such as SGI's).
 111         * (_initialize_sh_tdep):  Don't set remote_write_size.  It's now
 112         handled automatically in remote.c.
 113
 114 Thu Apr  3 15:10:30 1997  Michael Snyder  <msnyder@cleaver.cygnus.com>
 115
 116         * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
 117         find_pc_sect_function(), find_pc_sect_partial_function(): new
 118         functions for debugging overlays; pc without section is ambiguous.
 119         * breakpoint.[ch]: add section pointer to breakpoint struct;
 120         add section argument to check_duplicates(); check section as well
 121         as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
 122         breakpoint_thread_match(), bpstat_stop_status()];
 123         add section argument to describe_other_breakpoints();
 124         use INIT_SAL() macro to zero-out new sal structures;
 125         make resolve_sal_pc() fix up the sal's section as well as its pc;
 126         match on section + pc in clear_command() and delete_breakpoint();
 127         account for overlay sections in insert_breakpoints(),
 128         remove_breakpoint() and breakpoint_re_set_one();
 129         all this to support overlays where a PC is not unique.
 130         * exec.c: change xfer_memory() to handle overlay sections.
 131         * findvar.c: change read_var_value() to handle overlay sections.
 132         * frame.h: declaration for block_for_pc_sect() [blockframe.c].
 133         * infcmd.c: jump_command() warns against jumping into an overlay
 134         that's not in memory.  Also use INIT_SAL() to initialize sals.
 135         * infrun.c: wait_for_inferior() sets a flag to invalidate cached
 136         overlay state information; Also use INIT_SAL() to init sals.
 137         * m32r-rom.c: modify load routines to use LMA instead of VMA.
 138         * m32r-stub.c: mask exit value down to 8 bits; screen out any
 139         memory read/writes in the range 600000 to a00000, and ff680000
 140         to ff800000 (hangs because nothing is mapped there); fix strcpy().
 141         * maint.c: maintenance command "translate-address" supports overlays.
 142         * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
 143         * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
 144         this constitutes gdb's internal overlay mapping table.  Add macro
 145         ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
 146         Add function find_pc_sect_section().
 147         * printcmd.c: modify print_address_symbolic() with overlay smarts;
 148         modify address_info() with overlay smarts; add function sym_info()
 149         to support the INFO SYMBOL command (translate address to symbol(s));
 150         modify disassemble_command() to work on unmapped overlays.
 151         * source.c: use INIT_SAL() to initialize sals.
 152         * symfile.[ch]: change generic_load() to use section's LMA address
 153         instead of VMA address, for overlay sections.
 154         Add numerous functions for finding a PC's section / overlay,
 155         translating between VMA and LMA address ranges, determining if an
 156         overlay section is mapped, etc.  Add several user commands for
 157         overlay debugging.  Add support for a "generic" form of automatically
 158         reading overlay mapping info from the inferior (based on the default
 159         (simple) overlay manager which Cygnus provides as an example).
 160         * symtab.[ch]: add functions find_pc_sect_symtab(),
 161         find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
 162         for lookup; modify lookup_symbol and decode_line_1() to use them;
 163         modify find_function_start_sal() to account for overlay sections;
 164         add macro INIT_SAL() for initializing struct symtab_and_line.
 165         * target.c: fix a comment in the declaration of target_ops.
 166

 171         with MIPS16 call/return thunks.
 172         (mips_init_frame_pc_first): New function to implement
 173         INIT_FRAME_PC_FIRST macro; includes code from old macro plus
 174         new code to skip over MIPS16 thunks.
 175         (mips_frame_chain): Skip over MIPS16 thunks.
 176         * config/mips/tm-mips.h (mips_in_call_stub, mips_in_return_stub,
 177         mips_skip_stub, mips_ignore_helper): Declare.
 178         (IN_SOLIB_CALL_TRAMPOLINE, IN_SOLIB_RETURN_TRAMPOLINE,

 180         the above functions.
 181         (INIT_FRAME_PC_FIRST): Change to invoke mips_init_frame_pc.
 182         (mips_init_frame_pc): Declare.
 183         * infrun.c (wait_for_inferior): Use new IGNORE_HELPER_CALL macro
 184         to decide if certain library function calls should be ignored.

 260         stabs debugging info (continue on if a psymtab isn't found).
 261
 262 Sun Mar 23 16:19:20 1997  Mark Alexander  <marka@cygnus.com>
 263
 264         Fixes from Peter Schauer:

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