254 * defs.h utils.c (error warning): Make message be const.
255 * main.c (fputs_unfiltered): Only send gdb_stdout and gdb_stderr

259 * remote-e7000.c: Remove debugify stuff. Change printf, fprintf

261 uses of SERIAL_READCHAR with readchar, which has better error
263 * (e7000_parse_device): Add prototype.
264 (readchar): Improve doc. Handle random serial errors.
265 (expect): Disable notice_quit code. It's busted. Remove
266 serial error handling (it's now handled in readchar). Remove
267 remote_debug echoing. That's handled in readchar as well.
268 (e7000_parse_device): Remove serial_flag arg. It's not
270 (e7000_open): Split into two pieces. Second part is
271 e7000_start_remote, and is error protected. Now, when we connect
272 to the target, we setup the initial frame and registers so that
273 the user gets an immediate indication of where the target is.
274 (gch): Remove debug output. That's handled by readchar.
275 (e7000_read_inferior_memory): Handle errors better.
276 (_initialize_remote_e7000): Get rid of `<xxx>' things from

282 * (serial_logchar serial_log_command serial_write serial_readchar
283 serial_send_break serial_close): Merge common functionality into

310 (gdb_os_poll_quit): New function. Check for a quit pending on the
314 Wed Apr 16 12:33:06 1997 Andrew Cagney <cagney@b1.cygnus.com>
316 * Makefile.in (install-only): Make list of gdbtcl files to install
317 explicit - was picking up files such as ChangeLog etc.

349 * gdbserver/Makefile.in (INSTALL_XFORM): Remove.
350 (INSTALL_XFORM1): Remove.
351 (install-only): Use $(program_transform_name) directly, rather
352 than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).

355 Mon Apr 14 17:06:27 1997 Mark Alexander <marka@cygnus.com>
357 * remote-mips.c (mips_load): Ensure that PC gets updated

364 Mon Apr 14 16:25:10 1997 Ian Lance Taylor <ian@cygnus.com>

369 Mon Apr 14 11:55:27 1997 Geoffrey Noer <noer@pizza.cygnus.com>
371 * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
372 since gcc automatically includes it
374 Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>
376 * procfs.c: Substantial (but incomplete) changes to support
377 sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
378 struct now has substructs like struct flt_ctl instead of
379 just a fltset_t and has a ctl_fd, status_fd, as_fd, and
380 map_fd instead of a single fd. Non-sysv4.2mp procfs models
381 still have the structs and multiple fds, but don't use the
382 entire struct and the four fds all point to the same thing.
383 We use PROCFS_USE_READ_WRITE to decide whether to talk to
384 procfs with reads/writes or use ioctl instead. We use
385 HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
386 multiple fds or not. PROC_NAME_FMT is split out into
387 CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
388 STATUS_PROC_NAME_FMT.
390 (procfs_notice_signals): now a necessary wrapper around
391 (notice_signals): which are the new guts for noticing signals
392 (open_proc_file): gets a new flag arg used in sysv4.2mp to
393 determine whether or not to attempt to open the ctl_fd.
394 (procfs_read_status): new local function, reads procfs status
395 (procfs_write_pcwstop): new local function, writes a PCWSTOP
396 (procfs_write_pckill): new local function, writes a PCKILL
397 (unconditionally_kill_inferior): remove signo since we now
398 just call procfs_write_pckill().
399 (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
400 (proc_iterate_over_mappings): the whole function is ifdefed
401 on UNIXWARE to keep things readable.
403 Expanded the syscall_table to include new potential sysv4.2mp
404 members. Note that all ifdefs of UNIXWARE should be eliminated
405 if possible or renamed to describe what's being selected for a
406 bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
407 IRIX specific code now also checks it's not UNIXWARE.
409 * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
410 HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
411 * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
412 "/debug/%d" as PROC_NAME_FMT used to be
414 Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com)
416 * mn10300-tdep.c: Almost completely rewritten based on mn10200
418 * config/mn10300/tm-mn10300.h: Likewise.
420 Tue Apr 8 10:45:24 1997 Stu Grossman (grossman@critters.cygnus.com)
422 * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
423 remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
424 lousy out-of-date clone of remote.c.
426 Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
428 * remote.c: Fix problems realized while showering.
429 * (hexnumlen): Add prototype. Use max, not min.
430 * (remote_write_bytes remote_read_bytes): Fix max packet size
431 calculations to properly account for packet overhead. Also handle
432 (probably rare) case where remote_register_buf_size isn't set.
434 * remote.c: Fix doc for `C' and `S' commands to indicate full
436 * (remote_ops extended_remote_ops remote_desc remote_write_size):
438 * (remote_fetch_registers remote_write_bytes remote_read_bytes):
439 Record size of response to fetch registers command, use this to
440 limit size of memory read and write commands.
441 * (push_remote_target): New function to make it possible to have
442 another target switch to the remote target.
443 * target.h: Add prototype for push_remote_target.
444 * sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
445 for hosts which default to unsigned chars (such as SGI's).
446 * (_initialize_sh_tdep): Don't set remote_write_size. It's now
447 handled automatically in remote.c.
449 Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
451 * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
452 find_pc_sect_function(), find_pc_sect_partial_function(): new
453 functions for debugging overlays; pc without section is ambiguous.
454 * breakpoint.[ch]: add section pointer to breakpoint struct;
455 add section argument to check_duplicates(); check section as well
456 as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
457 breakpoint_thread_match(), bpstat_stop_status()];
458 add section argument to describe_other_breakpoints();
459 use INIT_SAL() macro to zero-out new sal structures;
460 make resolve_sal_pc() fix up the sal's section as well as its pc;
461 match on section + pc in clear_command() and delete_breakpoint();
462 account for overlay sections in insert_breakpoints(),
463 remove_breakpoint() and breakpoint_re_set_one();
464 all this to support overlays where a PC is not unique.
465 * exec.c: change xfer_memory() to handle overlay sections.
466 * findvar.c: change read_var_value() to handle overlay sections.
467 * frame.h: declaration for block_for_pc_sect() [blockframe.c].
468 * infcmd.c: jump_command() warns against jumping into an overlay
469 that's not in memory. Also use INIT_SAL() to initialize sals.
470 * infrun.c: wait_for_inferior() sets a flag to invalidate cached
471 overlay state information; Also use INIT_SAL() to init sals.
472 * m32r-rom.c: modify load routines to use LMA instead of VMA.
473 * m32r-stub.c: mask exit value down to 8 bits; screen out any
474 memory read/writes in the range 600000 to a00000, and ff680000
475 to ff800000 (hangs because nothing is mapped there); fix strcpy().
476 * maint.c: maintenance command "translate-address" supports overlays.
477 * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
478 * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
479 this constitutes gdb's internal overlay mapping table. Add macro
480 ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
