 100 Fri Apr 18 17:25:10 1997  Stu Grossman  (grossman@critters.cygnus.com)
 101
 102         * Makefile.in (SUBDIRS):  Add mswin so that make cleanup cleans up
 103         that directory.
 104         * defs.h utils.c (error warning):  Make message be const.
 105         * main.c (fputs_unfiltered):  Only send gdb_stdout and gdb_stderr
 106         to hook.  Otherwise send it to fputs.
 107         * monitor.c monitor.h (monitor_get_dev_name):  New function.  Does
 108         the obvious.
 109         * remote-e7000.c:  Remove debugify stuff.  Change printf, fprintf
 110         to _filtered forms to make output appear in GUIs.  Replace all
 111         uses of SERIAL_READCHAR with readchar, which has better error
 112         checking.
 113         * (e7000_parse_device):  Add prototype.
 114         (readchar):  Improve doc.  Handle random serial errors.
 115         (expect):  Disable notice_quit code.  It's busted.  Remove
 116         serial error handling (it's now handled in readchar).  Remove
 117         remote_debug echoing.  That's handled in readchar as well.
 118         (e7000_parse_device):  Remove serial_flag arg.  It's not
 119         necessary.
 120         (e7000_open):  Split into two pieces.  Second part is
 121         e7000_start_remote, and is error protected.  Now, when we connect
 122         to the target, we setup the initial frame and registers so that
 123         the user gets an immediate indication of where the target is.
 124         (gch):  Remove debug output.  That's handled by readchar.
 125         (e7000_read_inferior_memory):  Handle errors better.
 126         (_initialize_remote_e7000):  Get rid of `<xxx>' things from
 127         command names.  They show up when doing completion and confuse
 128         things horribly.
 129         * ser-e7kpc.c: Get rid of the DLL's since we can access the device
 130         directly from Win32s and Win95.  Get rid of debugify crud.
 131         * serial.c:  Remove debugify cruft.
 132         * (serial_logchar serial_log_command serial_write serial_readchar
 133         serial_send_break serial_close):  Merge common functionality into
 134         serial_logchar.  Clean up rest of routines.
 135         * sparclet-rom.c:  Disembowel.  Leave only download routine.
 136         Download routine now switches to remote target automatically.
 137         * top.c (disconnect):  Only define if SIGHUP is defined.  Cleans
 138         up MSVC/Win32 problem.
 139         * utils.c (gdb_flush):  Don't call hook unless it's for gdb_stdout
 140         or gdb_stderr.
 141         * config/sh/tm-sh.h:  Define TARGET_SH for WinGDB.
 142         * config/sparc/tm-sparclet.h:  Remove override for prompt.

 147         TARGET_BYTE ORDER_SELECTABLE.

 152         fields of gdb_callback.
 153         (gdbsim_stop): Add gdbsim_stop to list of supported client
 154         operations.
 155         (gdbsim_wait, gdbsim_resume): Move call to sim_resume into
 156         sim_wait where gdb is in a position to handle a long running
 157         function.
 158         (gdbsim_cntrl_c): New function.  Wrap the sim_resume call in a
 159         SIGINT handler.
 160         (gdb_os_poll_quit): New function. Check for a quit pending on the
 161         console.

 167         explicit - was picking up files such as ChangeLog etc.
 168         (install-only): Don't blindly create the directory.

 175         * Makefile.in:  Update for new files.
 176         * objfiles.c (allocate_objfile):  Allow NULL bfd argument.

 200         (INSTALL_XFORM1): Remove.
 201         (install-only): Use $(program_transform_name) directly, rather
 202         than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).

 219 Mon Apr 14 11:55:27 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
 220
 221         * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
 222         since gcc automatically includes it
 223
 224 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
 225
 226         * procfs.c: Substantial (but incomplete) changes to support
 227         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
 228         struct now has substructs like struct flt_ctl instead of
 229         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 230         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 231         still have the structs and multiple fds, but don't use the
 232         entire struct and the four fds all point to the same thing.
 233         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 234         procfs with reads/writes or use ioctl instead.  We use
 235         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 236         multiple fds or not.  PROC_NAME_FMT is split out into
 237         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 238         STATUS_PROC_NAME_FMT.
 239
 240         (procfs_notice_signals): now a necessary wrapper around
 241         (notice_signals): which are the new guts for noticing signals
 242         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 243         determine whether or not to attempt to open the ctl_fd.
 244         (procfs_read_status): new local function, reads procfs status
 245         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 246         (procfs_write_pckill): new local function, writes a PCKILL
 247         (unconditionally_kill_inferior): remove signo since we now
 248         just call procfs_write_pckill().
 249         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 250         (proc_iterate_over_mappings): the whole function is ifdefed
 251         on UNIXWARE to keep things readable.
 252
 253         Expanded the syscall_table to include new potential sysv4.2mp
 254         members.  Note that all ifdefs of UNIXWARE should be eliminated
 255         if possible or renamed to describe what's being selected for a
 256         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 257         IRIX specific code now also checks it's not UNIXWARE.
 258
 259         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
 260         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
 261         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
 262         "/debug/%d" as PROC_NAME_FMT used to be
 263
 264 Wed Apr  9 11:36:14 1997  Jeffrey A Law  (law@cygnus.com)
 265
 266         * mn10300-tdep.c: Almost completely rewritten based on mn10200
 267         port.
 268         * config/mn10300/tm-mn10300.h: Likewise.

 270 Tue Apr  8 10:45:24 1997  Stu Grossman  (grossman@critters.cygnus.com)
 271
 272         * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
 273         remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
 274         lousy out-of-date clone of remote.c.
 275
 276 Fri Apr  4 08:21:21 1997  Stu Grossman  (grossman@critters.cygnus.com)
 277
 278         * remote.c:  Fix problems realized while showering.
 279         * (hexnumlen):  Add prototype.  Use max, not min.
 280         * (remote_write_bytes remote_read_bytes):  Fix max packet size
 281         calculations to properly account for packet overhead.  Also handle
 282         (probably rare) case where remote_register_buf_size isn't set.
 283
 284         * remote.c:  Fix doc for `C' and `S' commands to indicate full
 285         address.
 286         * (remote_ops extended_remote_ops remote_desc remote_write_size):
 287         Make static.
 288         * (remote_fetch_registers remote_write_bytes remote_read_bytes):
 289         Record size of response to fetch registers command, use this to
 290         limit size of memory read and write commands.
 291         * (push_remote_target):  New function to make it possible to have
 292         another target switch to the remote target.
 293         * target.h:  Add prototype for push_remote_target.
 294         * sh-tdep.c (sh_frame_find_saved_regs):  Fix sign extension bugs
 295         for hosts which default to unsigned chars (such as SGI's).
 296         * (_initialize_sh_tdep):  Don't set remote_write_size.  It's now
 297         handled automatically in remote.c.

 299 Thu Apr  3 15:10:30 1997  Michael Snyder  <msnyder@cleaver.cygnus.com>
 300
 301         * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
 302         find_pc_sect_function(), find_pc_sect_partial_function(): new
 303         functions for debugging overlays; pc without section is ambiguous.
 304         * breakpoint.[ch]: add section pointer to breakpoint struct;
 305         add section argument to check_duplicates(); check section as well
 306         as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
 307         breakpoint_thread_match(), bpstat_stop_status()];
 308         add section argument to describe_other_breakpoints();
 309         use INIT_SAL() macro to zero-out new sal structures;
 310         make resolve_sal_pc() fix up the sal's section as well as its pc;
 311         match on section + pc in clear_command() and delete_breakpoint();
 312         account for overlay sections in insert_breakpoints(),
 313         remove_breakpoint() and breakpoint_re_set_one();
 314         all this to support overlays where a PC is not unique.
 315         * exec.c: change xfer_memory() to handle overlay sections.
 316         * findvar.c: change read_var_value() to handle overlay sections.
 317         * frame.h: declaration for block_for_pc_sect() [blockframe.c].
 318         * infcmd.c: jump_command() warns against jumping into an overlay
 319         that's not in memory.  Also use INIT_SAL() to initialize sals.
 320         * infrun.c: wait_for_inferior() sets a flag to invalidate cached
 321         overlay state information; Also use INIT_SAL() to init sals.

 329         this constitutes gdb's internal overlay mapping table.  Add macro
 330         ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.

 337         * symfile.[ch]: change generic_load() to use section's LMA address
 338         instead of VMA address, for overlay sections.
 339         Add numerous functions for finding a PC's section / overlay,
 340         translating between VMA and LMA address ranges, determining if an
 341         overlay section is mapped, etc.  Add several user commands for
 342         overlay debugging.  Add support for a "generic" form of automatically
 343         reading overlay mapping info from the inferior (based on the default
 344         (simple) overlay manager which Cygnus provides as an example).
 345         * symtab.[ch]: add functions find_pc_sect_symtab(),
 346         find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
 347         for lookup; modify lookup_symbol and decode_line_1() to use them;
 348         modify find_function_start_sal() to account for overlay sections;
 349         add macro INIT_SAL() for initializing struct symtab_and_line.
 350         * target.c: fix a comment in the declaration of target_ops.
