1118 * remote-e7000.c: Remove debugify stuff. Change printf, fprintf
1119 to _filtered forms to make output appear in GUIs. Replace all
1120 uses of SERIAL_READCHAR with readchar, which has better error
1122 * (e7000_parse_device): Add prototype.
1123 (readchar): Improve doc. Handle random serial errors.
1124 (expect): Disable notice_quit code. It's busted. Remove

1126 remote_debug echoing. That's handled in readchar as well.
1127 (e7000_parse_device): Remove serial_flag arg. It's not
1129 (e7000_open): Split into two pieces. Second part is
1130 e7000_start_remote, and is error protected. Now, when we connect
1131 to the target, we setup the initial frame and registers so that
1132 the user gets an immediate indication of where the target is.
1133 (gch): Remove debug output. That's handled by readchar.
1134 (e7000_read_inferior_memory): Handle errors better.
1135 (_initialize_remote_e7000): Get rid of `<xxx>' things from
1136 command names. They show up when doing completion and confuse

1212 (uninstall): Transform name.
1214 Mon Apr 14 17:06:27 1997 Mark Alexander <marka@cygnus.com>

1230 * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
1231 since gcc automatically includes it
1233 Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>
1235 * procfs.c: Substantial (but incomplete) changes to support
1236 sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
1237 struct now has substructs like struct flt_ctl instead of
1238 just a fltset_t and has a ctl_fd, status_fd, as_fd, and
1239 map_fd instead of a single fd. Non-sysv4.2mp procfs models
1240 still have the structs and multiple fds, but don't use the
1241 entire struct and the four fds all point to the same thing.
1242 We use PROCFS_USE_READ_WRITE to decide whether to talk to
1243 procfs with reads/writes or use ioctl instead. We use
1244 HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
1245 multiple fds or not. PROC_NAME_FMT is split out into
1246 CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
1247 STATUS_PROC_NAME_FMT.
1249 (procfs_notice_signals): now a necessary wrapper around
1250 (notice_signals): which are the new guts for noticing signals
1251 (open_proc_file): gets a new flag arg used in sysv4.2mp to
1252 determine whether or not to attempt to open the ctl_fd.
1253 (procfs_read_status): new local function, reads procfs status
1254 (procfs_write_pcwstop): new local function, writes a PCWSTOP
1255 (procfs_write_pckill): new local function, writes a PCKILL
1256 (unconditionally_kill_inferior): remove signo since we now
1257 just call procfs_write_pckill().
1258 (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
1259 (proc_iterate_over_mappings): the whole function is ifdefed
1260 on UNIXWARE to keep things readable.
1262 Expanded the syscall_table to include new potential sysv4.2mp
1263 members. Note that all ifdefs of UNIXWARE should be eliminated
1264 if possible or renamed to describe what's being selected for a
1265 bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
1266 IRIX specific code now also checks it's not UNIXWARE.
1268 * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
1269 HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
1270 * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
1271 "/debug/%d" as PROC_NAME_FMT used to be
1273 Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com)
1275 * mn10300-tdep.c: Almost completely rewritten based on mn10200
1277 * config/mn10300/tm-mn10300.h: Likewise.
1279 Tue Apr 8 10:45:24 1997 Stu Grossman (grossman@critters.cygnus.com)
1281 * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
1282 remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
1283 lousy out-of-date clone of remote.c.
1285 Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
1287 * remote.c: Fix problems realized while showering.
1288 * (hexnumlen): Add prototype. Use max, not min.
1289 * (remote_write_bytes remote_read_bytes): Fix max packet size
1290 calculations to properly account for packet overhead. Also handle
1291 (probably rare) case where remote_register_buf_size isn't set.
1293 * remote.c: Fix doc for `C' and `S' commands to indicate full
1295 * (remote_ops extended_remote_ops remote_desc remote_write_size):
1297 * (remote_fetch_registers remote_write_bytes remote_read_bytes):
1298 Record size of response to fetch registers command, use this to
1299 limit size of memory read and write commands.
1300 * (push_remote_target): New function to make it possible to have
1301 another target switch to the remote target.
1302 * target.h: Add prototype for push_remote_target.
1303 * sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
1304 for hosts which default to unsigned chars (such as SGI's).
1305 * (_initialize_sh_tdep): Don't set remote_write_size. It's now
1306 handled automatically in remote.c.
1308 Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
1310 * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
1311 find_pc_sect_function(), find_pc_sect_partial_function(): new
1312 functions for debugging overlays; pc without section is ambiguous.
1313 * breakpoint.[ch]: add section pointer to breakpoint struct;
1314 add section argument to check_duplicates(); check section as well
1315 as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
1316 breakpoint_thread_match(), bpstat_stop_status()];
1317 add section argument to describe_other_breakpoints();
1318 use INIT_SAL() macro to zero-out new sal structures;
1319 make resolve_sal_pc() fix up the sal's section as well as its pc;
1320 match on section + pc in clear_command() and delete_breakpoint();
1321 account for overlay sections in insert_breakpoints(),
1322 remove_breakpoint() and breakpoint_re_set_one();
1323 all this to support overlays where a PC is not unique.
1324 * exec.c: change xfer_memory() to handle overlay sections.
1325 * findvar.c: change read_var_value() to handle overlay sections.
1326 * frame.h: declaration for block_for_pc_sect() [blockframe.c].
1327 * infcmd.c: jump_command() warns against jumping into an overlay
1328 that's not in memory. Also use INIT_SAL() to initialize sals.
1329 * infrun.c: wait_for_inferior() sets a flag to invalidate cached
1330 overlay state information; Also use INIT_SAL() to init sals.
1331 * m32r-rom.c: modify load routines to use LMA instead of VMA.
1332 * m32r-stub.c: mask exit value down to 8 bits; screen out any
1333 memory read/writes in the range 600000 to a00000, and ff680000
1334 to ff800000 (hangs because nothing is mapped there); fix strcpy().
1335 * maint.c: maintenance command "translate-address" supports overlays.
1336 * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
1337 * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
1338 this constitutes gdb's internal overlay mapping table. Add macro
1339 ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
1340 Add function find_pc_sect_section().
1341 * printcmd.c: modify print_address_symbolic() with overlay smarts;
1342 modify address_info() with overlay smarts; add function sym_info()
1343 to support the INFO SYMBOL command (translate address to symbol(s));
1344 modify disassemble_command() to work on unmapped overlays.
1345 * source.c: use INIT_SAL() to initialize sals.
1346 * symfile.[ch]: change generic_load() to use section's LMA address
1347 instead of VMA address, for overlay sections.
1348 Add numerous functions for finding a PC's section / overlay,
1349 translating between VMA and LMA address ranges, determining if an
1350 overlay section is mapped, etc. Add several user commands for
1351 overlay debugging. Add support for a "generic" form of automatically
1352 reading overlay mapping info from the inferior (based on the default
1353 (simple) overlay manager which Cygnus provides as an example).
1354 * symtab.[ch]: add functions find_pc_sect_symtab(),
1355 find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
1356 for lookup; modify lookup_symbol and decode_line_1() to use them;
1357 modify find_function_start_sal() to account for overlay sections;
1358 add macro INIT_SAL() for initializing struct symtab_and_line.
1359 * target.c: fix a comment in the declaration of target_ops.
1361 Thu Apr 3 10:31:12 1997 Mark Alexander <marka@cygnus.com>
1363 * mips-tdep.c (mips_in_call_stub, mips_in_return_stub,

1372 (IN_SOLIB_CALL_TRAMPOLINE, IN_SOLIB_RETURN_TRAMPOLINE,
1373 SKIP_TRAMPOLINE_CODE, IGNORE_HELPER_CALL): New macros that invoke
1374 the above functions.
1375 (INIT_FRAME_PC_FIRST): Change to invoke mips_init_frame_pc.
1376 (mips_init_frame_pc): Declare.
1377 * infrun.c (wait_for_inferior): Use new IGNORE_HELPER_CALL macro
1378 to decide if certain library function calls should be ignored.
