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

132 * (e7000_parse_device): Add prototype.
133 (readchar): Improve doc. Handle random serial errors.
134 (expect): Disable notice_quit code. It's busted. Remove
135 serial error handling (it's now handled in readchar). Remove
136 remote_debug echoing. That's handled in readchar as well.
137 (e7000_parse_device): Remove serial_flag arg. It's not
139 (e7000_open): Split into two pieces. Second part is
140 e7000_start_remote, and is error protected. Now, when we connect
141 to the target, we setup the initial frame and registers so that
142 the user gets an immediate indication of where the target is.
143 (gch): Remove debug output. That's handled by readchar.
144 (e7000_read_inferior_memory): Handle errors better.
145 (_initialize_remote_e7000): Get rid of `<xxx>' things from

240 * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
241 since gcc automatically includes it
243 Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>
245 * procfs.c: Substantial (but incomplete) changes to support
246 sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
247 struct now has substructs like struct flt_ctl instead of
248 just a fltset_t and has a ctl_fd, status_fd, as_fd, and
249 map_fd instead of a single fd. Non-sysv4.2mp procfs models
250 still have the structs and multiple fds, but don't use the
251 entire struct and the four fds all point to the same thing.
252 We use PROCFS_USE_READ_WRITE to decide whether to talk to
253 procfs with reads/writes or use ioctl instead. We use
254 HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
255 multiple fds or not. PROC_NAME_FMT is split out into
256 CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
257 STATUS_PROC_NAME_FMT.
259 (procfs_notice_signals): now a necessary wrapper around
260 (notice_signals): which are the new guts for noticing signals
261 (open_proc_file): gets a new flag arg used in sysv4.2mp to
262 determine whether or not to attempt to open the ctl_fd.
263 (procfs_read_status): new local function, reads procfs status
264 (procfs_write_pcwstop): new local function, writes a PCWSTOP
265 (procfs_write_pckill): new local function, writes a PCKILL
266 (unconditionally_kill_inferior): remove signo since we now
267 just call procfs_write_pckill().
268 (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
269 (proc_iterate_over_mappings): the whole function is ifdefed
270 on UNIXWARE to keep things readable.
272 Expanded the syscall_table to include new potential sysv4.2mp
273 members. Note that all ifdefs of UNIXWARE should be eliminated
274 if possible or renamed to describe what's being selected for a
275 bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
276 IRIX specific code now also checks it's not UNIXWARE.
278 * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
279 HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
280 * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
281 "/debug/%d" as PROC_NAME_FMT used to be
283 Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com)
285 * mn10300-tdep.c: Almost completely rewritten based on mn10200
287 * config/mn10300/tm-mn10300.h: Likewise.
289 Tue Apr 8 10:45:24 1997 Stu Grossman (grossman@critters.cygnus.com)
291 * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
292 remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
293 lousy out-of-date clone of remote.c.
295 Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
297 * remote.c: Fix problems realized while showering.
298 * (hexnumlen): Add prototype. Use max, not min.
299 * (remote_write_bytes remote_read_bytes): Fix max packet size
300 calculations to properly account for packet overhead. Also handle
301 (probably rare) case where remote_register_buf_size isn't set.
303 * remote.c: Fix doc for `C' and `S' commands to indicate full
305 * (remote_ops extended_remote_ops remote_desc remote_write_size):
307 * (remote_fetch_registers remote_write_bytes remote_read_bytes):
308 Record size of response to fetch registers command, use this to
309 limit size of memory read and write commands.
310 * (push_remote_target): New function to make it possible to have
311 another target switch to the remote target.
312 * target.h: Add prototype for push_remote_target.
313 * sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
314 for hosts which default to unsigned chars (such as SGI's).
315 * (_initialize_sh_tdep): Don't set remote_write_size. It's now
316 handled automatically in remote.c.
318 Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
320 * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
321 find_pc_sect_function(), find_pc_sect_partial_function(): new
322 functions for debugging overlays; pc without section is ambiguous.
323 * breakpoint.[ch]: add section pointer to breakpoint struct;
324 add section argument to check_duplicates(); check section as well
325 as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
326 breakpoint_thread_match(), bpstat_stop_status()];
327 add section argument to describe_other_breakpoints();
328 use INIT_SAL() macro to zero-out new sal structures;
329 make resolve_sal_pc() fix up the sal's section as well as its pc;
330 match on section + pc in clear_command() and delete_breakpoint();
331 account for overlay sections in insert_breakpoints(),
332 remove_breakpoint() and breakpoint_re_set_one();
333 all this to support overlays where a PC is not unique.
334 * exec.c: change xfer_memory() to handle overlay sections.
335 * findvar.c: change read_var_value() to handle overlay sections.
336 * frame.h: declaration for block_for_pc_sect() [blockframe.c].
337 * infcmd.c: jump_command() warns against jumping into an overlay
338 that's not in memory. Also use INIT_SAL() to initialize sals.
339 * infrun.c: wait_for_inferior() sets a flag to invalidate cached
340 overlay state information; Also use INIT_SAL() to init sals.
341 * m32r-rom.c: modify load routines to use LMA instead of VMA.
342 * m32r-stub.c: mask exit value down to 8 bits; screen out any
343 memory read/writes in the range 600000 to a00000, and ff680000
344 to ff800000 (hangs because nothing is mapped there); fix strcpy().
345 * maint.c: maintenance command "translate-address" supports overlays.
346 * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
347 * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
348 this constitutes gdb's internal overlay mapping table. Add macro
349 ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
350 Add function find_pc_sect_section().
351 * printcmd.c: modify print_address_symbolic() with overlay smarts;
352 modify address_info() with overlay smarts; add function sym_info()
353 to support the INFO SYMBOL command (translate address to symbol(s));
354 modify disassemble_command() to work on unmapped overlays.
355 * source.c: use INIT_SAL() to initialize sals.
356 * symfile.[ch]: change generic_load() to use section's LMA address
357 instead of VMA address, for overlay sections.
358 Add numerous functions for finding a PC's section / overlay,
359 translating between VMA and LMA address ranges, determining if an
360 overlay section is mapped, etc. Add several user commands for
361 overlay debugging. Add support for a "generic" form of automatically
362 reading overlay mapping info from the inferior (based on the default
363 (simple) overlay manager which Cygnus provides as an example).
364 * symtab.[ch]: add functions find_pc_sect_symtab(),
365 find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
366 for lookup; modify lookup_symbol and decode_line_1() to use them;
367 modify find_function_start_sal() to account for overlay sections;
368 add macro INIT_SAL() for initializing struct symtab_and_line.
369 * target.c: fix a comment in the declaration of target_ops.
371 Thu Apr 3 10:31:12 1997 Mark Alexander <marka@cygnus.com>
373 * mips-tdep.c (mips_in_call_stub, mips_in_return_stub,
374 mips_skip_stub, mips_ignore_helper): New functions for dealing
375 with MIPS16 call/return thunks.
376 (mips_init_frame_pc_first): New function to implement
377 INIT_FRAME_PC_FIRST macro; includes code from old macro plus
378 new code to skip over MIPS16 thunks.
379 (mips_frame_chain): Skip over MIPS16 thunks.
380 * config/mips/tm-mips.h (mips_in_call_stub, mips_in_return_stub,
