1062 Mon Apr 14 11:55:27 1997 Geoffrey Noer <noer@pizza.cygnus.com>
1064 * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
1065 since gcc automatically includes it
1067 Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>
1069 * procfs.c: Substantial (but incomplete) changes to support
1070 sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
1071 struct now has substructs like struct flt_ctl instead of
1072 just a fltset_t and has a ctl_fd, status_fd, as_fd, and
1073 map_fd instead of a single fd. Non-sysv4.2mp procfs models
1074 still have the structs and multiple fds, but don't use the
1075 entire struct and the four fds all point to the same thing.
1076 We use PROCFS_USE_READ_WRITE to decide whether to talk to
1077 procfs with reads/writes or use ioctl instead. We use
1078 HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
1079 multiple fds or not. PROC_NAME_FMT is split out into
1080 CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
1081 STATUS_PROC_NAME_FMT.
1083 (procfs_notice_signals): now a necessary wrapper around
1084 (notice_signals): which are the new guts for noticing signals
1085 (open_proc_file): gets a new flag arg used in sysv4.2mp to
1086 determine whether or not to attempt to open the ctl_fd.
1087 (procfs_read_status): new local function, reads procfs status
1088 (procfs_write_pcwstop): new local function, writes a PCWSTOP
1089 (procfs_write_pckill): new local function, writes a PCKILL
1090 (unconditionally_kill_inferior): remove signo since we now
1091 just call procfs_write_pckill().
1092 (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
1093 (proc_iterate_over_mappings): the whole function is ifdefed
1094 on UNIXWARE to keep things readable.
1096 Expanded the syscall_table to include new potential sysv4.2mp
1097 members. Note that all ifdefs of UNIXWARE should be eliminated
1098 if possible or renamed to describe what's being selected for a
1099 bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
1100 IRIX specific code now also checks it's not UNIXWARE.
1102 * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
1103 HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
1104 * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
1105 "/debug/%d" as PROC_NAME_FMT used to be
1107 Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com)
1109 * mn10300-tdep.c: Almost completely rewritten based on mn10200
1111 * config/mn10300/tm-mn10300.h: Likewise.
1113 Tue Apr 8 10:45:24 1997 Stu Grossman (grossman@critters.cygnus.com)
1115 * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
1116 remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
1117 lousy out-of-date clone of remote.c.
1119 Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
1121 * remote.c: Fix problems realized while showering.
1122 * (hexnumlen): Add prototype. Use max, not min.
1123 * (remote_write_bytes remote_read_bytes): Fix max packet size
1124 calculations to properly account for packet overhead. Also handle
1125 (probably rare) case where remote_register_buf_size isn't set.
1127 * remote.c: Fix doc for `C' and `S' commands to indicate full
1129 * (remote_ops extended_remote_ops remote_desc remote_write_size):
1131 * (remote_fetch_registers remote_write_bytes remote_read_bytes):
1132 Record size of response to fetch registers command, use this to
1133 limit size of memory read and write commands.
1134 * (push_remote_target): New function to make it possible to have
1135 another target switch to the remote target.
1136 * target.h: Add prototype for push_remote_target.
1137 * sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
1138 for hosts which default to unsigned chars (such as SGI's).
1139 * (_initialize_sh_tdep): Don't set remote_write_size. It's now
1140 handled automatically in remote.c.
1142 Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
1144 * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
1145 find_pc_sect_function(), find_pc_sect_partial_function(): new
1146 functions for debugging overlays; pc without section is ambiguous.
1147 * breakpoint.[ch]: add section pointer to breakpoint struct;
1148 add section argument to check_duplicates(); check section as well
1149 as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
1150 breakpoint_thread_match(), bpstat_stop_status()];
1151 add section argument to describe_other_breakpoints();
1152 use INIT_SAL() macro to zero-out new sal structures;
1153 make resolve_sal_pc() fix up the sal's section as well as its pc;
1154 match on section + pc in clear_command() and delete_breakpoint();
1155 account for overlay sections in insert_breakpoints(),
1156 remove_breakpoint() and breakpoint_re_set_one();
1157 all this to support overlays where a PC is not unique.
1158 * exec.c: change xfer_memory() to handle overlay sections.
1159 * findvar.c: change read_var_value() to handle overlay sections.
1160 * frame.h: declaration for block_for_pc_sect() [blockframe.c].
1161 * infcmd.c: jump_command() warns against jumping into an overlay
1162 that's not in memory. Also use INIT_SAL() to initialize sals.
1163 * infrun.c: wait_for_inferior() sets a flag to invalidate cached
1164 overlay state information; Also use INIT_SAL() to init sals.
1165 * m32r-rom.c: modify load routines to use LMA instead of VMA.
1166 * m32r-stub.c: mask exit value down to 8 bits; screen out any
1167 memory read/writes in the range 600000 to a00000, and ff680000
1168 to ff800000 (hangs because nothing is mapped there); fix strcpy().
1169 * maint.c: maintenance command "translate-address" supports overlays.
1170 * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
1171 * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
1172 this constitutes gdb's internal overlay mapping table. Add macro
1173 ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
1174 Add function find_pc_sect_section().
1175 * printcmd.c: modify print_address_symbolic() with overlay smarts;
1176 modify address_info() with overlay smarts; add function sym_info()
1177 to support the INFO SYMBOL command (translate address to symbol(s));
1178 modify disassemble_command() to work on unmapped overlays.
1179 * source.c: use INIT_SAL() to initialize sals.
1180 * symfile.[ch]: change generic_load() to use section's LMA address
1181 instead of VMA address, for overlay sections.
1182 Add numerous functions for finding a PC's section / overlay,
1183 translating between VMA and LMA address ranges, determining if an
1184 overlay section is mapped, etc. Add several user commands for
1185 overlay debugging. Add support for a "generic" form of automatically
1186 reading overlay mapping info from the inferior (based on the default
1187 (simple) overlay manager which Cygnus provides as an example).
1188 * symtab.[ch]: add functions find_pc_sect_symtab(),
1189 find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
1190 for lookup; modify lookup_symbol and decode_line_1() to use them;
1191 modify find_function_start_sal() to account for overlay sections;
1192 add macro INIT_SAL() for initializing struct symtab_and_line.
1193 * target.c: fix a comment in the declaration of target_ops.
1195 Thu Apr 3 10:31:12 1997 Mark Alexander <marka@cygnus.com>
1197 * mips-tdep.c (mips_in_call_stub, mips_in_return_stub,

1208 the above functions.
1209 (INIT_FRAME_PC_FIRST): Change to invoke mips_init_frame_pc.
1210 (mips_init_frame_pc): Declare.
1211 * infrun.c (wait_for_inferior): Use new IGNORE_HELPER_CALL macro
1212 to decide if certain library function calls should be ignored.

1342 strings that may precede functions in the text section. Remove
1343 now-useless lowest_pdr_addr from argument list and all calls.
1345 Fri Mar 21 15:36:25 1997 Michael Meissner <meissner@cygnus.com>

1959 * mn10300-tdep.c: made a lot more generic, ripping out code
1960 from copied target (no more mn10300_scan_prologue,
1961 init_extra_frame_info, and mn10300_fix_call_dummy calls)
1962 * config/mn10300/tm-mn10300.h: undefine INIT_EXTRA_FRAME_INFO
1963 and INIT_FRAME_PC macros

1967 * sparc-tdep.c (sparc_frame_find_saved_regs): Don't use
1968 FP_REGISTER_BYTES to compute offsets into the saved frame,
1969 since it fails for SPARC targets configured without any
1970 FP regs. Instead, use DUMMY_STACK_REG_BUF_SIZE.

1989 value_at and value_at_lazy.
1990 * coffread.c dbxread.c elfread.c mdebugread.c minsyms.c symtab.h:
1991 Add bfd_section arg to prim_record_minimal_symbol_and_info.
1992 * corefile.c gdbcore.h printcmd.c valops.c: Use read_memory_section
1993 instead of read_memory. It takes a bfd_section arg.
1994 * coffread.c dbxread.c elfread.c gdb-stabs.h objfiles.h: Remove
1995 unnecessary cast for assignment of struct dbx_symfile_info.
1996 Struct objfile now uses a real pointer instead of PTR for this
1998 * dbxread.c (dbx_symfile_init): Stash bfd section pointers for
1999 text, data and bss into dbx_symfile_info.

2018 add section info to symbols returned by lookup_symbol.
2019 * symtab.h (struct general_symbol_info): Add bfd section to
2021 * target.c target.h (target_xfer_memory): Add bfd section to
2023 * (target_read_memory_section): New routine to read data from a
2025 * (target_memory_bfd_section): New global variable to pass bfd
2026 section in to targets.
2027 * valarith.c (value_add value_addr value_array): Preserve bfd
2028 section when computing new value.
2029 * value.h (struct value): Add bfd section to values.
2030 * values.c (allocate_value value_copy): Initialize/preserve bfd

2044 * mn10300-tdep.c (mn10300_push_arguments): rewrote,
2045 also removed code elsewhere that made use of RP_REGNUM.
2046 * config/mn10300/tm-mn10300.h: ripped out RP_REGNUM, V0_REGNUM,
2047 ARG0_REGNUM, ARGLAST_REGNUM (all not appropriate for mn10300
2048 arch.), redefined SAVED_PC_AFTER_CALL, EXTRACT_RETURN_VALUE,
2049 EXTRACT_STRUCT_VALUE_ADDRESS, STORE_RETURN_VALUE.
