1164 to _filtered forms to make output appear in GUIs. Replace all
1165 uses of SERIAL_READCHAR with readchar, which has better error
1167 * (e7000_parse_device): Add prototype.
1168 (readchar): Improve doc. Handle random serial errors.
1169 (expect): Disable notice_quit code. It's busted. Remove
1170 serial error handling (it's now handled in readchar). Remove
1171 remote_debug echoing. That's handled in readchar as well.
1172 (e7000_parse_device): Remove serial_flag arg. It's not
1174 (e7000_open): Split into two pieces. Second part is
1175 e7000_start_remote, and is error protected. Now, when we connect
1176 to the target, we setup the initial frame and registers so that
1177 the user gets an immediate indication of where the target is.
1178 (gch): Remove debug output. That's handled by readchar.
1179 (e7000_read_inferior_memory): Handle errors better.
1180 (_initialize_remote_e7000): Get rid of `<xxx>' things from
1181 command names. They show up when doing completion and confuse

1184 directly from Win32s and Win95. Get rid of debugify crud.
1185 * serial.c: Remove debugify cruft.
1186 * (serial_logchar serial_log_command serial_write serial_readchar

1254 (INSTALL_XFORM1): Remove.
1255 (install-only): Use $(program_transform_name) directly, rather

1257 (uninstall): Transform name.
1259 Mon Apr 14 17:06:27 1997 Mark Alexander <marka@cygnus.com>

1276 since gcc automatically includes it
1278 Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>
1280 * procfs.c: Substantial (but incomplete) changes to support
1281 sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
1282 struct now has substructs like struct flt_ctl instead of
1283 just a fltset_t and has a ctl_fd, status_fd, as_fd, and
1284 map_fd instead of a single fd. Non-sysv4.2mp procfs models
1285 still have the structs and multiple fds, but don't use the
1286 entire struct and the four fds all point to the same thing.
1287 We use PROCFS_USE_READ_WRITE to decide whether to talk to
1288 procfs with reads/writes or use ioctl instead. We use
1289 HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
1290 multiple fds or not. PROC_NAME_FMT is split out into
1291 CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
1292 STATUS_PROC_NAME_FMT.
1294 (procfs_notice_signals): now a necessary wrapper around
1295 (notice_signals): which are the new guts for noticing signals
1296 (open_proc_file): gets a new flag arg used in sysv4.2mp to
1297 determine whether or not to attempt to open the ctl_fd.
1298 (procfs_read_status): new local function, reads procfs status
1299 (procfs_write_pcwstop): new local function, writes a PCWSTOP
1300 (procfs_write_pckill): new local function, writes a PCKILL
1301 (unconditionally_kill_inferior): remove signo since we now
1302 just call procfs_write_pckill().
1303 (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
1304 (proc_iterate_over_mappings): the whole function is ifdefed
1305 on UNIXWARE to keep things readable.
1307 Expanded the syscall_table to include new potential sysv4.2mp
1308 members. Note that all ifdefs of UNIXWARE should be eliminated
1309 if possible or renamed to describe what's being selected for a
1310 bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
1311 IRIX specific code now also checks it's not UNIXWARE.
1313 * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
1314 HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
1315 * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
1316 "/debug/%d" as PROC_NAME_FMT used to be
1318 Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com)
1320 * mn10300-tdep.c: Almost completely rewritten based on mn10200
1322 * config/mn10300/tm-mn10300.h: Likewise.
1324 Tue Apr 8 10:45:24 1997 Stu Grossman (grossman@critters.cygnus.com)
1326 * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
1327 remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
1328 lousy out-of-date clone of remote.c.
1330 Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
1332 * remote.c: Fix problems realized while showering.
1333 * (hexnumlen): Add prototype. Use max, not min.
1334 * (remote_write_bytes remote_read_bytes): Fix max packet size
1335 calculations to properly account for packet overhead. Also handle
1336 (probably rare) case where remote_register_buf_size isn't set.
1338 * remote.c: Fix doc for `C' and `S' commands to indicate full
1340 * (remote_ops extended_remote_ops remote_desc remote_write_size):
1342 * (remote_fetch_registers remote_write_bytes remote_read_bytes):
1343 Record size of response to fetch registers command, use this to
1344 limit size of memory read and write commands.
1345 * (push_remote_target): New function to make it possible to have
1346 another target switch to the remote target.
1347 * target.h: Add prototype for push_remote_target.
1348 * sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
1349 for hosts which default to unsigned chars (such as SGI's).
1350 * (_initialize_sh_tdep): Don't set remote_write_size. It's now
1351 handled automatically in remote.c.
1353 Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
1355 * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
1356 find_pc_sect_function(), find_pc_sect_partial_function(): new
1357 functions for debugging overlays; pc without section is ambiguous.
1358 * breakpoint.[ch]: add section pointer to breakpoint struct;
1359 add section argument to check_duplicates(); check section as well
1360 as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
1361 breakpoint_thread_match(), bpstat_stop_status()];
1362 add section argument to describe_other_breakpoints();
1363 use INIT_SAL() macro to zero-out new sal structures;
1364 make resolve_sal_pc() fix up the sal's section as well as its pc;
1365 match on section + pc in clear_command() and delete_breakpoint();
1366 account for overlay sections in insert_breakpoints(),
1367 remove_breakpoint() and breakpoint_re_set_one();
1368 all this to support overlays where a PC is not unique.
1369 * exec.c: change xfer_memory() to handle overlay sections.
1370 * findvar.c: change read_var_value() to handle overlay sections.
1371 * frame.h: declaration for block_for_pc_sect() [blockframe.c].
1372 * infcmd.c: jump_command() warns against jumping into an overlay
1373 that's not in memory. Also use INIT_SAL() to initialize sals.
1374 * infrun.c: wait_for_inferior() sets a flag to invalidate cached
1375 overlay state information; Also use INIT_SAL() to init sals.
1376 * m32r-rom.c: modify load routines to use LMA instead of VMA.
1377 * m32r-stub.c: mask exit value down to 8 bits; screen out any
1378 memory read/writes in the range 600000 to a00000, and ff680000
1379 to ff800000 (hangs because nothing is mapped there); fix strcpy().
1380 * maint.c: maintenance command "translate-address" supports overlays.
1381 * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
1382 * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
1383 this constitutes gdb's internal overlay mapping table. Add macro
1384 ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
1385 Add function find_pc_sect_section().
1386 * printcmd.c: modify print_address_symbolic() with overlay smarts;
1387 modify address_info() with overlay smarts; add function sym_info()
1388 to support the INFO SYMBOL command (translate address to symbol(s));
1389 modify disassemble_command() to work on unmapped overlays.
1390 * source.c: use INIT_SAL() to initialize sals.
1391 * symfile.[ch]: change generic_load() to use section's LMA address
1392 instead of VMA address, for overlay sections.
1393 Add numerous functions for finding a PC's section / overlay,
1394 translating between VMA and LMA address ranges, determining if an
1395 overlay section is mapped, etc. Add several user commands for
1396 overlay debugging. Add support for a "generic" form of automatically
1397 reading overlay mapping info from the inferior (based on the default
1398 (simple) overlay manager which Cygnus provides as an example).
1399 * symtab.[ch]: add functions find_pc_sect_symtab(),
1400 find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
1401 for lookup; modify lookup_symbol and decode_line_1() to use them;
1402 modify find_function_start_sal() to account for overlay sections;
1403 add macro INIT_SAL() for initializing struct symtab_and_line.
1404 * target.c: fix a comment in the declaration of target_ops.
1406 Thu Apr 3 10:31:12 1997 Mark Alexander <marka@cygnus.com>
1408 * mips-tdep.c (mips_in_call_stub, mips_in_return_stub,

1417 (IN_SOLIB_CALL_TRAMPOLINE, IN_SOLIB_RETURN_TRAMPOLINE,
1418 SKIP_TRAMPOLINE_CODE, IGNORE_HELPER_CALL): New macros that invoke
1419 the above functions.
1420 (INIT_FRAME_PC_FIRST): Change to invoke mips_init_frame_pc.
1421 (mips_init_frame_pc): Declare.
1422 * infrun.c (wait_for_inferior): Use new IGNORE_HELPER_CALL macro
1423 to decide if certain library function calls should be ignored.
