226 * defs.h utils.c (error warning): Make message be const.
227 * main.c (fputs_unfiltered): Only send gdb_stdout and gdb_stderr
228 to hook. Otherwise send it to fputs.

231 * remote-e7000.c: Remove debugify stuff. Change printf, fprintf
232 to _filtered forms to make output appear in GUIs. Replace all
233 uses of SERIAL_READCHAR with readchar, which has better error
235 * (e7000_parse_device): Add prototype.
236 (readchar): Improve doc. Handle random serial errors.
237 (expect): Disable notice_quit code. It's busted. Remove
238 serial error handling (it's now handled in readchar). Remove
239 remote_debug echoing. That's handled in readchar as well.
240 (e7000_parse_device): Remove serial_flag arg. It's not
242 (e7000_open): Split into two pieces. Second part is
243 e7000_start_remote, and is error protected. Now, when we connect
244 to the target, we setup the initial frame and registers so that
245 the user gets an immediate indication of where the target is.
246 (gch): Remove debug output. That's handled by readchar.
247 (e7000_read_inferior_memory): Handle errors better.
248 (_initialize_remote_e7000): Get rid of `<xxx>' things from
249 command names. They show up when doing completion and confuse

252 directly from Win32s and Win95. Get rid of debugify crud.
253 * serial.c: Remove debugify cruft.
254 * (serial_logchar serial_log_command serial_write serial_readchar
255 serial_send_break serial_close): Merge common functionality into

321 * gdbserver/Makefile.in (INSTALL_XFORM): Remove.
322 (INSTALL_XFORM1): Remove.
323 (install-only): Use $(program_transform_name) directly, rather

343 * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
344 since gcc automatically includes it
346 Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>
348 * procfs.c: Substantial (but incomplete) changes to support
349 sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
350 struct now has substructs like struct flt_ctl instead of
351 just a fltset_t and has a ctl_fd, status_fd, as_fd, and
352 map_fd instead of a single fd. Non-sysv4.2mp procfs models
353 still have the structs and multiple fds, but don't use the
354 entire struct and the four fds all point to the same thing.
355 We use PROCFS_USE_READ_WRITE to decide whether to talk to
356 procfs with reads/writes or use ioctl instead. We use
357 HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
358 multiple fds or not. PROC_NAME_FMT is split out into
359 CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
360 STATUS_PROC_NAME_FMT.
362 (procfs_notice_signals): now a necessary wrapper around
363 (notice_signals): which are the new guts for noticing signals
364 (open_proc_file): gets a new flag arg used in sysv4.2mp to
365 determine whether or not to attempt to open the ctl_fd.
366 (procfs_read_status): new local function, reads procfs status
367 (procfs_write_pcwstop): new local function, writes a PCWSTOP
368 (procfs_write_pckill): new local function, writes a PCKILL
369 (unconditionally_kill_inferior): remove signo since we now
370 just call procfs_write_pckill().
371 (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
372 (proc_iterate_over_mappings): the whole function is ifdefed
373 on UNIXWARE to keep things readable.
375 Expanded the syscall_table to include new potential sysv4.2mp
376 members. Note that all ifdefs of UNIXWARE should be eliminated
377 if possible or renamed to describe what's being selected for a
378 bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
379 IRIX specific code now also checks it's not UNIXWARE.
381 * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
382 HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
383 * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
384 "/debug/%d" as PROC_NAME_FMT used to be
386 Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com)
388 * mn10300-tdep.c: Almost completely rewritten based on mn10200
390 * config/mn10300/tm-mn10300.h: Likewise.
392 Tue Apr 8 10:45:24 1997 Stu Grossman (grossman@critters.cygnus.com)
394 * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
395 remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
396 lousy out-of-date clone of remote.c.
398 Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
400 * remote.c: Fix problems realized while showering.
401 * (hexnumlen): Add prototype. Use max, not min.
402 * (remote_write_bytes remote_read_bytes): Fix max packet size
403 calculations to properly account for packet overhead. Also handle
404 (probably rare) case where remote_register_buf_size isn't set.
406 * remote.c: Fix doc for `C' and `S' commands to indicate full
408 * (remote_ops extended_remote_ops remote_desc remote_write_size):
410 * (remote_fetch_registers remote_write_bytes remote_read_bytes):
411 Record size of response to fetch registers command, use this to
412 limit size of memory read and write commands.
413 * (push_remote_target): New function to make it possible to have
414 another target switch to the remote target.
415 * target.h: Add prototype for push_remote_target.
416 * sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
417 for hosts which default to unsigned chars (such as SGI's).
418 * (_initialize_sh_tdep): Don't set remote_write_size. It's now
419 handled automatically in remote.c.
421 Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
423 * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
424 find_pc_sect_function(), find_pc_sect_partial_function(): new
425 functions for debugging overlays; pc without section is ambiguous.
426 * breakpoint.[ch]: add section pointer to breakpoint struct;
427 add section argument to check_duplicates(); check section as well
428 as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
429 breakpoint_thread_match(), bpstat_stop_status()];
430 add section argument to describe_other_breakpoints();
431 use INIT_SAL() macro to zero-out new sal structures;
432 make resolve_sal_pc() fix up the sal's section as well as its pc;
433 match on section + pc in clear_command() and delete_breakpoint();
434 account for overlay sections in insert_breakpoints(),
435 remove_breakpoint() and breakpoint_re_set_one();
436 all this to support overlays where a PC is not unique.
437 * exec.c: change xfer_memory() to handle overlay sections.
438 * findvar.c: change read_var_value() to handle overlay sections.
439 * frame.h: declaration for block_for_pc_sect() [blockframe.c].
440 * infcmd.c: jump_command() warns against jumping into an overlay
441 that's not in memory. Also use INIT_SAL() to initialize sals.
442 * infrun.c: wait_for_inferior() sets a flag to invalidate cached
443 overlay state information; Also use INIT_SAL() to init sals.
444 * m32r-rom.c: modify load routines to use LMA instead of VMA.
445 * m32r-stub.c: mask exit value down to 8 bits; screen out any
446 memory read/writes in the range 600000 to a00000, and ff680000
447 to ff800000 (hangs because nothing is mapped there); fix strcpy().
448 * maint.c: maintenance command "translate-address" supports overlays.
449 * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
450 * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
451 this constitutes gdb's internal overlay mapping table. Add macro
452 ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
453 Add function find_pc_sect_section().
454 * printcmd.c: modify print_address_symbolic() with overlay smarts;
455 modify address_info() with overlay smarts; add function sym_info()
456 to support the INFO SYMBOL command (translate address to symbol(s));
457 modify disassemble_command() to work on unmapped overlays.
458 * source.c: use INIT_SAL() to initialize sals.
459 * symfile.[ch]: change generic_load() to use section's LMA address
460 instead of VMA address, for overlay sections.
461 Add numerous functions for finding a PC's section / overlay,
462 translating between VMA and LMA address ranges, determining if an
463 overlay section is mapped, etc. Add several user commands for
464 overlay debugging. Add support for a "generic" form of automatically
465 reading overlay mapping info from the inferior (based on the default
466 (simple) overlay manager which Cygnus provides as an example).
467 * symtab.[ch]: add functions find_pc_sect_symtab(),
468 find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
469 for lookup; modify lookup_symbol and decode_line_1() to use them;
470 modify find_function_start_sal() to account for overlay sections;
471 add macro INIT_SAL() for initializing struct symtab_and_line.
472 * target.c: fix a comment in the declaration of target_ops.
