18 * java-exp.y: Combine TRUE and FALSE into BOOLEAN_LITERAL.
19 (Avoids name clash with broken AIX header files.)

47 Fri Apr 18 17:25:10 1997 Stu Grossman (grossman@critters.cygnus.com)
49 * Makefile.in (SUBDIRS): Add mswin so that make cleanup cleans up
51 * defs.h utils.c (error warning): Make message be const.
52 * main.c (fputs_unfiltered): Only send gdb_stdout and gdb_stderr
53 to hook. Otherwise send it to fputs.

60 * (e7000_parse_device): Add prototype.
61 (readchar): Improve doc. Handle random serial errors.
62 (expect): Disable notice_quit code. It's busted. Remove
63 serial error handling (it's now handled in readchar). Remove
64 remote_debug echoing. That's handled in readchar as well.
65 (e7000_parse_device): Remove serial_flag arg. It's not
67 (e7000_open): Split into two pieces. Second part is
68 e7000_start_remote, and is error protected. Now, when we connect
69 to the target, we setup the initial frame and registers so that
70 the user gets an immediate indication of where the target is.
71 (gch): Remove debug output. That's handled by readchar.
72 (e7000_read_inferior_memory): Handle errors better.
73 (_initialize_remote_e7000): Get rid of `<xxx>' things from
74 command names. They show up when doing completion and confuse
76 * ser-e7kpc.c: Get rid of the DLL's since we can access the device

78 * serial.c: Remove debugify cruft.
79 * (serial_logchar serial_log_command serial_write serial_readchar
80 serial_send_break serial_close): Merge common functionality into

166 Mon Apr 14 11:55:27 1997 Geoffrey Noer <noer@pizza.cygnus.com>
168 * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
169 since gcc automatically includes it
171 Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>
173 * procfs.c: Substantial (but incomplete) changes to support
174 sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
175 struct now has substructs like struct flt_ctl instead of
176 just a fltset_t and has a ctl_fd, status_fd, as_fd, and
177 map_fd instead of a single fd. Non-sysv4.2mp procfs models
178 still have the structs and multiple fds, but don't use the
179 entire struct and the four fds all point to the same thing.
180 We use PROCFS_USE_READ_WRITE to decide whether to talk to
181 procfs with reads/writes or use ioctl instead. We use
182 HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
183 multiple fds or not. PROC_NAME_FMT is split out into
184 CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
185 STATUS_PROC_NAME_FMT.
187 (procfs_notice_signals): now a necessary wrapper around
188 (notice_signals): which are the new guts for noticing signals
189 (open_proc_file): gets a new flag arg used in sysv4.2mp to
190 determine whether or not to attempt to open the ctl_fd.
191 (procfs_read_status): new local function, reads procfs status
192 (procfs_write_pcwstop): new local function, writes a PCWSTOP
193 (procfs_write_pckill): new local function, writes a PCKILL
194 (unconditionally_kill_inferior): remove signo since we now
195 just call procfs_write_pckill().
196 (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
197 (proc_iterate_over_mappings): the whole function is ifdefed
198 on UNIXWARE to keep things readable.
200 Expanded the syscall_table to include new potential sysv4.2mp
201 members. Note that all ifdefs of UNIXWARE should be eliminated
202 if possible or renamed to describe what's being selected for a
203 bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
204 IRIX specific code now also checks it's not UNIXWARE.
206 * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
207 HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
208 * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
209 "/debug/%d" as PROC_NAME_FMT used to be
211 Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com)
213 * mn10300-tdep.c: Almost completely rewritten based on mn10200
215 * config/mn10300/tm-mn10300.h: Likewise.
217 Tue Apr 8 10:45:24 1997 Stu Grossman (grossman@critters.cygnus.com)
219 * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
220 remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
221 lousy out-of-date clone of remote.c.
223 Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
225 * remote.c: Fix problems realized while showering.
226 * (hexnumlen): Add prototype. Use max, not min.
227 * (remote_write_bytes remote_read_bytes): Fix max packet size
228 calculations to properly account for packet overhead. Also handle
229 (probably rare) case where remote_register_buf_size isn't set.
231 * remote.c: Fix doc for `C' and `S' commands to indicate full
233 * (remote_ops extended_remote_ops remote_desc remote_write_size):
235 * (remote_fetch_registers remote_write_bytes remote_read_bytes):
236 Record size of response to fetch registers command, use this to
237 limit size of memory read and write commands.
238 * (push_remote_target): New function to make it possible to have
239 another target switch to the remote target.
240 * target.h: Add prototype for push_remote_target.
241 * sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
242 for hosts which default to unsigned chars (such as SGI's).
243 * (_initialize_sh_tdep): Don't set remote_write_size. It's now
244 handled automatically in remote.c.
246 Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
248 * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
249 find_pc_sect_function(), find_pc_sect_partial_function(): new
250 functions for debugging overlays; pc without section is ambiguous.
251 * breakpoint.[ch]: add section pointer to breakpoint struct;
252 add section argument to check_duplicates(); check section as well
253 as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
254 breakpoint_thread_match(), bpstat_stop_status()];
255 add section argument to describe_other_breakpoints();
256 use INIT_SAL() macro to zero-out new sal structures;
257 make resolve_sal_pc() fix up the sal's section as well as its pc;
258 match on section + pc in clear_command() and delete_breakpoint();
259 account for overlay sections in insert_breakpoints(),
260 remove_breakpoint() and breakpoint_re_set_one();
261 all this to support overlays where a PC is not unique.
262 * exec.c: change xfer_memory() to handle overlay sections.
263 * findvar.c: change read_var_value() to handle overlay sections.
264 * frame.h: declaration for block_for_pc_sect() [blockframe.c].
265 * infcmd.c: jump_command() warns against jumping into an overlay
266 that's not in memory. Also use INIT_SAL() to initialize sals.
267 * infrun.c: wait_for_inferior() sets a flag to invalidate cached
268 overlay state information; Also use INIT_SAL() to init sals.
269 * m32r-rom.c: modify load routines to use LMA instead of VMA.
270 * m32r-stub.c: mask exit value down to 8 bits; screen out any
271 memory read/writes in the range 600000 to a00000, and ff680000
272 to ff800000 (hangs because nothing is mapped there); fix strcpy().
273 * maint.c: maintenance command "translate-address" supports overlays.
274 * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
275 * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
276 this constitutes gdb's internal overlay mapping table. Add macro
277 ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
278 Add function find_pc_sect_section().
279 * printcmd.c: modify print_address_symbolic() with overlay smarts;
280 modify address_info() with overlay smarts; add function sym_info()
281 to support the INFO SYMBOL command (translate address to symbol(s));
282 modify disassemble_command() to work on unmapped overlays.
283 * source.c: use INIT_SAL() to initialize sals.
284 * symfile.[ch]: change generic_load() to use section's LMA address
285 instead of VMA address, for overlay sections.
286 Add numerous functions for finding a PC's section / overlay,
287 translating between VMA and LMA address ranges, determining if an
288 overlay section is mapped, etc. Add several user commands for
289 overlay debugging. Add support for a "generic" form of automatically
290 reading overlay mapping info from the inferior (based on the default
291 (simple) overlay manager which Cygnus provides as an example).
292 * symtab.[ch]: add functions find_pc_sect_symtab(),
293 find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
294 for lookup; modify lookup_symbol and decode_line_1() to use them;
295 modify find_function_start_sal() to account for overlay sections;
296 add macro INIT_SAL() for initializing struct symtab_and_line.
297 * target.c: fix a comment in the declaration of target_ops.
299 Thu Apr 3 10:31:12 1997 Mark Alexander <marka@cygnus.com>
301 * mips-tdep.c (mips_in_call_stub, mips_in_return_stub,
302 mips_skip_stub, mips_ignore_helper): New functions for dealing
303 with MIPS16 call/return thunks.
304 (mips_init_frame_pc_first): New function to implement
305 INIT_FRAME_PC_FIRST macro; includes code from old macro plus
306 new code to skip over MIPS16 thunks.
307 (mips_frame_chain): Skip over MIPS16 thunks.
308 * config/mips/tm-mips.h (mips_in_call_stub, mips_in_return_stub,
