1055 Mon Apr 14 11:55:27 1997 Geoffrey Noer <noer@pizza.cygnus.com>
1057 * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
1058 since gcc automatically includes it
1060 Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>
1062 * procfs.c: Substantial (but incomplete) changes to support
1063 sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
1064 struct now has substructs like struct flt_ctl instead of
1065 just a fltset_t and has a ctl_fd, status_fd, as_fd, and
1066 map_fd instead of a single fd. Non-sysv4.2mp procfs models
1067 still have the structs and multiple fds, but don't use the
1068 entire struct and the four fds all point to the same thing.
1069 We use PROCFS_USE_READ_WRITE to decide whether to talk to
1070 procfs with reads/writes or use ioctl instead. We use
1071 HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
1072 multiple fds or not. PROC_NAME_FMT is split out into
1073 CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
1074 STATUS_PROC_NAME_FMT.
1076 (procfs_notice_signals): now a necessary wrapper around
1077 (notice_signals): which are the new guts for noticing signals
1078 (open_proc_file): gets a new flag arg used in sysv4.2mp to
1079 determine whether or not to attempt to open the ctl_fd.
1080 (procfs_read_status): new local function, reads procfs status
1081 (procfs_write_pcwstop): new local function, writes a PCWSTOP
1082 (procfs_write_pckill): new local function, writes a PCKILL
1083 (unconditionally_kill_inferior): remove signo since we now
1084 just call procfs_write_pckill().
1085 (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
1086 (proc_iterate_over_mappings): the whole function is ifdefed
1087 on UNIXWARE to keep things readable.
1089 Expanded the syscall_table to include new potential sysv4.2mp
1090 members. Note that all ifdefs of UNIXWARE should be eliminated
1091 if possible or renamed to describe what's being selected for a
1092 bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
1093 IRIX specific code now also checks it's not UNIXWARE.
1095 * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
1096 HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
1097 * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
1098 "/debug/%d" as PROC_NAME_FMT used to be
1100 Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com)
1102 * mn10300-tdep.c: Almost completely rewritten based on mn10200
1104 * config/mn10300/tm-mn10300.h: Likewise.
1106 Tue Apr 8 10:45:24 1997 Stu Grossman (grossman@critters.cygnus.com)
1108 * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
1109 remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
1110 lousy out-of-date clone of remote.c.
1112 Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
1114 * remote.c: Fix problems realized while showering.
1115 * (hexnumlen): Add prototype. Use max, not min.
1116 * (remote_write_bytes remote_read_bytes): Fix max packet size
1117 calculations to properly account for packet overhead. Also handle
1118 (probably rare) case where remote_register_buf_size isn't set.
1120 * remote.c: Fix doc for `C' and `S' commands to indicate full
1122 * (remote_ops extended_remote_ops remote_desc remote_write_size):
1124 * (remote_fetch_registers remote_write_bytes remote_read_bytes):
1125 Record size of response to fetch registers command, use this to
1126 limit size of memory read and write commands.
1127 * (push_remote_target): New function to make it possible to have
1128 another target switch to the remote target.
1129 * target.h: Add prototype for push_remote_target.
1130 * sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
1131 for hosts which default to unsigned chars (such as SGI's).
1132 * (_initialize_sh_tdep): Don't set remote_write_size. It's now
1133 handled automatically in remote.c.
1135 Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
1137 * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
1138 find_pc_sect_function(), find_pc_sect_partial_function(): new
1139 functions for debugging overlays; pc without section is ambiguous.
1140 * breakpoint.[ch]: add section pointer to breakpoint struct;
1141 add section argument to check_duplicates(); check section as well
1142 as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
1143 breakpoint_thread_match(), bpstat_stop_status()];
1144 add section argument to describe_other_breakpoints();
1145 use INIT_SAL() macro to zero-out new sal structures;
1146 make resolve_sal_pc() fix up the sal's section as well as its pc;
1147 match on section + pc in clear_command() and delete_breakpoint();
1148 account for overlay sections in insert_breakpoints(),
1149 remove_breakpoint() and breakpoint_re_set_one();
1150 all this to support overlays where a PC is not unique.
1151 * exec.c: change xfer_memory() to handle overlay sections.
1152 * findvar.c: change read_var_value() to handle overlay sections.
1153 * frame.h: declaration for block_for_pc_sect() [blockframe.c].
1154 * infcmd.c: jump_command() warns against jumping into an overlay
1155 that's not in memory. Also use INIT_SAL() to initialize sals.
1156 * infrun.c: wait_for_inferior() sets a flag to invalidate cached
1157 overlay state information; Also use INIT_SAL() to init sals.
1158 * m32r-rom.c: modify load routines to use LMA instead of VMA.
1159 * m32r-stub.c: mask exit value down to 8 bits; screen out any
1160 memory read/writes in the range 600000 to a00000, and ff680000
1161 to ff800000 (hangs because nothing is mapped there); fix strcpy().
1162 * maint.c: maintenance command "translate-address" supports overlays.
1163 * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
1164 * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
1165 this constitutes gdb's internal overlay mapping table. Add macro
1166 ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
1167 Add function find_pc_sect_section().
1168 * printcmd.c: modify print_address_symbolic() with overlay smarts;
1169 modify address_info() with overlay smarts; add function sym_info()
1170 to support the INFO SYMBOL command (translate address to symbol(s));
1171 modify disassemble_command() to work on unmapped overlays.
1172 * source.c: use INIT_SAL() to initialize sals.
1173 * symfile.[ch]: change generic_load() to use section's LMA address
1174 instead of VMA address, for overlay sections.
1175 Add numerous functions for finding a PC's section / overlay,
1176 translating between VMA and LMA address ranges, determining if an
1177 overlay section is mapped, etc. Add several user commands for
1178 overlay debugging. Add support for a "generic" form of automatically
1179 reading overlay mapping info from the inferior (based on the default
1180 (simple) overlay manager which Cygnus provides as an example).
1181 * symtab.[ch]: add functions find_pc_sect_symtab(),
1182 find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
1183 for lookup; modify lookup_symbol and decode_line_1() to use them;
1184 modify find_function_start_sal() to account for overlay sections;
1185 add macro INIT_SAL() for initializing struct symtab_and_line.
1186 * target.c: fix a comment in the declaration of target_ops.
1188 Thu Apr 3 10:31:12 1997 Mark Alexander <marka@cygnus.com>
1190 * mips-tdep.c (mips_in_call_stub, mips_in_return_stub,

1201 the above functions.
1202 (INIT_FRAME_PC_FIRST): Change to invoke mips_init_frame_pc.
1203 (mips_init_frame_pc): Declare.
1204 * infrun.c (wait_for_inferior): Use new IGNORE_HELPER_CALL macro
1205 to decide if certain library function calls should be ignored.

1335 strings that may precede functions in the text section. Remove
1336 now-useless lowest_pdr_addr from argument list and all calls.
1338 Fri Mar 21 15:36:25 1997 Michael Meissner <meissner@cygnus.com>

1942 * blockframe.c (frameless_look_for_prologue): Mark frames
1943 with a zero PC as frameless to improve backtraces from core dumps
1944 caused by dereferencing a NULL function pointer.

1948 * config/mn10300/tm-mn10300.h: fix BREAKPOINT definition.
1950 Tue Jan 14 16:01:06 1997 Geoffrey Noer <noer@cygnus.com>
1952 * mn10300-tdep.c: made a lot more generic, ripping out code
1953 from copied target (no more mn10300_scan_prologue,
1954 init_extra_frame_info, and mn10300_fix_call_dummy calls)
1955 * config/mn10300/tm-mn10300.h: undefine INIT_EXTRA_FRAME_INFO
1956 and INIT_FRAME_PC macros
1958 Thu Jan 9 11:44:40 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
1960 * sparc-tdep.c (sparc_frame_find_saved_regs): Don't use
1961 FP_REGISTER_BYTES to compute offsets into the saved frame,
1962 since it fails for SPARC targets configured without any
1963 FP regs. Instead, use DUMMY_STACK_REG_BUF_SIZE.
1965 Mon Jan 6 11:15:14 1997 Stu Grossman (grossman@critters.cygnus.com)
1967 * symtab.c (fixup_symbol_section): Handle NULL symbols without

1972 * Makefile.in configure configure.in: Remove ENABLE_CLIBS,
1973 ENABLE_OBS, and THREAD_DB_OBS. These are consolidated into LIBS
1975 * configure configure.in: Clean up test cases around thread support.
1977 * configure.tgt (v850-*-*): Include v850ice.o and v850.lib if
1980 * c-valprint.c ch-valprint.c cp-valprint.c eval.c expprint.c
1981 printcmd.c valops.c value.h values.c: Add bfd_section arg to
1982 value_at and value_at_lazy.
1983 * coffread.c dbxread.c elfread.c mdebugread.c minsyms.c symtab.h:
1984 Add bfd_section arg to prim_record_minimal_symbol_and_info.
1985 * corefile.c gdbcore.h printcmd.c valops.c: Use read_memory_section
1986 instead of read_memory. It takes a bfd_section arg.
1987 * coffread.c dbxread.c elfread.c gdb-stabs.h objfiles.h: Remove
1988 unnecessary cast for assignment of struct dbx_symfile_info.
1989 Struct objfile now uses a real pointer instead of PTR for this
1991 * dbxread.c (dbx_symfile_init): Stash bfd section pointers for
1992 text, data and bss into dbx_symfile_info.
1993 * exec.c (xfer_memory): Handle transfers for user-specified
1995 * findvar.c (read_var_value locate_var_value): Copy bfd section
1996 from the symbol to the value.

1999 * maint.c (translate address command): Add test code for overlay
2000 address translation.
2001 * printcmd.c (do_examine do_one_display): Now takes a bfd section
2003 * (print_formatted x_command): Record current section along with
2004 current address for repeated commands.
2005 * sparc-nat.c (fetch_inferior_registers): Change
2006 target_xfer_memory to target_{read write}_memory to allow changes
2007 to target_xfer_memory interface for section info.
2008 * symmisc.c (dump_msymbols print_symbol): Print section
2009 assocaited with symbol.
2010 * symtab.c (fixup_symbol_section): New routine to
2011 add section info to symbols returned by lookup_symbol.
2012 * symtab.h (struct general_symbol_info): Add bfd section to
2014 * target.c target.h (target_xfer_memory): Add bfd section to
2016 * (target_read_memory_section): New routine to read data from a
2018 * (target_memory_bfd_section): New global variable to pass bfd
2019 section in to targets.
2020 * valarith.c (value_add value_addr value_array): Preserve bfd
2021 section when computing new value.
2022 * value.h (struct value): Add bfd section to values.
2023 * values.c (allocate_value value_copy): Initialize/preserve bfd
2025 * (unpack_double): Clean up _MSC_VER conditionals to remove
2028 * v850ice.c: New module to support communication with NEC's
2030 * config/v850/tm-v850.h (REGISTER_NAMES): Replace sp, gp, fp, and
2031 ep names with rxx names. sp and fp are renamed via a different

2037 * mn10300-tdep.c (mn10300_push_arguments): rewrote,
2038 also removed code elsewhere that made use of RP_REGNUM.
2039 * config/mn10300/tm-mn10300.h: ripped out RP_REGNUM, V0_REGNUM,
2040 ARG0_REGNUM, ARGLAST_REGNUM (all not appropriate for mn10300
2041 arch.), redefined SAVED_PC_AFTER_CALL, EXTRACT_RETURN_VALUE,
2042 EXTRACT_STRUCT_VALUE_ADDRESS, STORE_RETURN_VALUE.
