1097 Mon Apr 14 11:55:27 1997 Geoffrey Noer <noer@pizza.cygnus.com>
1099 * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
1100 since gcc automatically includes it
1102 Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>
1104 * procfs.c: Substantial (but incomplete) changes to support
1105 sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
1106 struct now has substructs like struct flt_ctl instead of
1107 just a fltset_t and has a ctl_fd, status_fd, as_fd, and
1108 map_fd instead of a single fd. Non-sysv4.2mp procfs models
1109 still have the structs and multiple fds, but don't use the
1110 entire struct and the four fds all point to the same thing.
1111 We use PROCFS_USE_READ_WRITE to decide whether to talk to
1112 procfs with reads/writes or use ioctl instead. We use
1113 HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
1114 multiple fds or not. PROC_NAME_FMT is split out into
1115 CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
1116 STATUS_PROC_NAME_FMT.
1118 (procfs_notice_signals): now a necessary wrapper around
1119 (notice_signals): which are the new guts for noticing signals
1120 (open_proc_file): gets a new flag arg used in sysv4.2mp to
1121 determine whether or not to attempt to open the ctl_fd.
1122 (procfs_read_status): new local function, reads procfs status
1123 (procfs_write_pcwstop): new local function, writes a PCWSTOP
1124 (procfs_write_pckill): new local function, writes a PCKILL
1125 (unconditionally_kill_inferior): remove signo since we now
1126 just call procfs_write_pckill().
1127 (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
1128 (proc_iterate_over_mappings): the whole function is ifdefed
1129 on UNIXWARE to keep things readable.
1131 Expanded the syscall_table to include new potential sysv4.2mp
1132 members. Note that all ifdefs of UNIXWARE should be eliminated
1133 if possible or renamed to describe what's being selected for a
1134 bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
1135 IRIX specific code now also checks it's not UNIXWARE.
1137 * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
1138 HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
1139 * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
1140 "/debug/%d" as PROC_NAME_FMT used to be
1142 Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com)
1144 * mn10300-tdep.c: Almost completely rewritten based on mn10200
1146 * config/mn10300/tm-mn10300.h: Likewise.
1148 Tue Apr 8 10:45:24 1997 Stu Grossman (grossman@critters.cygnus.com)
1150 * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
1151 remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
1152 lousy out-of-date clone of remote.c.
1154 Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
1156 * remote.c: Fix problems realized while showering.
1157 * (hexnumlen): Add prototype. Use max, not min.
1158 * (remote_write_bytes remote_read_bytes): Fix max packet size
1159 calculations to properly account for packet overhead. Also handle
1160 (probably rare) case where remote_register_buf_size isn't set.
1162 * remote.c: Fix doc for `C' and `S' commands to indicate full
1164 * (remote_ops extended_remote_ops remote_desc remote_write_size):
1166 * (remote_fetch_registers remote_write_bytes remote_read_bytes):
1167 Record size of response to fetch registers command, use this to
1168 limit size of memory read and write commands.
1169 * (push_remote_target): New function to make it possible to have
1170 another target switch to the remote target.
1171 * target.h: Add prototype for push_remote_target.
1172 * sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
1173 for hosts which default to unsigned chars (such as SGI's).
1174 * (_initialize_sh_tdep): Don't set remote_write_size. It's now
1175 handled automatically in remote.c.
1177 Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
1179 * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
1180 find_pc_sect_function(), find_pc_sect_partial_function(): new
1181 functions for debugging overlays; pc without section is ambiguous.
1182 * breakpoint.[ch]: add section pointer to breakpoint struct;
1183 add section argument to check_duplicates(); check section as well
1184 as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
1185 breakpoint_thread_match(), bpstat_stop_status()];
1186 add section argument to describe_other_breakpoints();
1187 use INIT_SAL() macro to zero-out new sal structures;
1188 make resolve_sal_pc() fix up the sal's section as well as its pc;
1189 match on section + pc in clear_command() and delete_breakpoint();
1190 account for overlay sections in insert_breakpoints(),
1191 remove_breakpoint() and breakpoint_re_set_one();
1192 all this to support overlays where a PC is not unique.
1193 * exec.c: change xfer_memory() to handle overlay sections.
1194 * findvar.c: change read_var_value() to handle overlay sections.
1195 * frame.h: declaration for block_for_pc_sect() [blockframe.c].
1196 * infcmd.c: jump_command() warns against jumping into an overlay
1197 that's not in memory. Also use INIT_SAL() to initialize sals.
1198 * infrun.c: wait_for_inferior() sets a flag to invalidate cached
1199 overlay state information; Also use INIT_SAL() to init sals.
1200 * m32r-rom.c: modify load routines to use LMA instead of VMA.
1201 * m32r-stub.c: mask exit value down to 8 bits; screen out any
1202 memory read/writes in the range 600000 to a00000, and ff680000
1203 to ff800000 (hangs because nothing is mapped there); fix strcpy().
1204 * maint.c: maintenance command "translate-address" supports overlays.
1205 * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
1206 * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
1207 this constitutes gdb's internal overlay mapping table. Add macro
1208 ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
1209 Add function find_pc_sect_section().
1210 * printcmd.c: modify print_address_symbolic() with overlay smarts;
1211 modify address_info() with overlay smarts; add function sym_info()
1212 to support the INFO SYMBOL command (translate address to symbol(s));
1213 modify disassemble_command() to work on unmapped overlays.
1214 * source.c: use INIT_SAL() to initialize sals.
1215 * symfile.[ch]: change generic_load() to use section's LMA address
1216 instead of VMA address, for overlay sections.
1217 Add numerous functions for finding a PC's section / overlay,
1218 translating between VMA and LMA address ranges, determining if an
1219 overlay section is mapped, etc. Add several user commands for
1220 overlay debugging. Add support for a "generic" form of automatically
1221 reading overlay mapping info from the inferior (based on the default
1222 (simple) overlay manager which Cygnus provides as an example).
1223 * symtab.[ch]: add functions find_pc_sect_symtab(),
1224 find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
1225 for lookup; modify lookup_symbol and decode_line_1() to use them;
1226 modify find_function_start_sal() to account for overlay sections;
1227 add macro INIT_SAL() for initializing struct symtab_and_line.
1228 * target.c: fix a comment in the declaration of target_ops.
1230 Thu Apr 3 10:31:12 1997 Mark Alexander <marka@cygnus.com>
1232 * mips-tdep.c (mips_in_call_stub, mips_in_return_stub,

1234 with MIPS16 call/return thunks.

1242 SKIP_TRAMPOLINE_CODE, IGNORE_HELPER_CALL): New macros that invoke
1243 the above functions.
1244 (INIT_FRAME_PC_FIRST): Change to invoke mips_init_frame_pc.
1245 (mips_init_frame_pc): Declare.
1246 * infrun.c (wait_for_inferior): Use new IGNORE_HELPER_CALL macro
1247 to decide if certain library function calls should be ignored.

1321 * symtab.c (find_pc_symtab): change to support the case
1322 where the objfile is reordered and contains both coff and

1373 on little-endian hosts.
1375 * mdebugread.c (parse_procedure): Adjust address of procedure relative
1376 to address in file descriptor record; this accounts for constant
1377 strings that may precede functions in the text section. Remove
1378 now-useless lowest_pdr_addr from argument list and all calls.
1380 Fri Mar 21 15:36:25 1997 Michael Meissner <meissner@cygnus.com>

2002 * sparc-tdep.c (sparc_frame_find_saved_regs): Don't use
2003 FP_REGISTER_BYTES to compute offsets into the saved frame,
2004 since it fails for SPARC targets configured without any

2082 ARG0_REGNUM, ARGLAST_REGNUM (all not appropriate for mn10300
2083 arch.), redefined SAVED_PC_AFTER_CALL, EXTRACT_RETURN_VALUE,
