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

38 * (e7000_parse_device): Add prototype.
39 * (readchar): Improve doc. Handle random serial errors.
40 * (expect): Disable notice_quit code. It's busted. Remove

43 * (e7000_parse_device): Remove serial_flag arg. It's not
45 * (e7000_open): Split into two pieces. Second part is
46 e7000_start_remote, and is error protected. Now, when we connect
47 to the target, we setup the initial frame and registers so that
48 the user gets an immediate indication of where the target is.
49 * (gch): Remove debug output. That's handled by readchar.
50 * (e7000_read_inferior_memory): Handle errors better.
51 * (_initialize_remote_e7000): Get rid of `<xxx>' things from
52 command names. They show up when doing completion and confuse
54 * ser-e7kpc.c: Remove the last seven months of brain damage. Get
55 rid of the DLL's since we can access the device directly from Win32s
56 and Win95. Get rid of debugify crud.
57 * serial.c: Remove debugify cruft.
58 * (serial_logchar serial_log_command serial_write serial_readchar

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

282 with MIPS16 call/return thunks.
283 (mips_init_frame_pc_first): New function to implement
