1016 Tue Apr 15 15:31:09 1997 Stan Shebs <shebs@andros.cygnus.com>
1018 * remote.c (get_offsets): Don't use scanf for interpreting
1019 response to qOffsets.
1021 Tue Apr 15 14:51:04 1997 Ian Lance Taylor <ian@cygnus.com>
1023 * gdbserver/Makefile.in (INSTALL_XFORM): Remove.
1024 (INSTALL_XFORM1): Remove.
1025 (install-only): Use $(program_transform_name) directly, rather
1026 than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).
1027 (uninstall): Transform name.
1029 Mon Apr 14 17:06:27 1997 Mark Alexander <marka@cygnus.com>
1031 * remote-mips.c (mips_load): Ensure that PC gets updated
1032 after a load on LSI target.
1034 Mon Apr 14 15:54:51 1997 Geoffrey Noer <noer@pizza.cygnus.com>
1036 * procfs.c (notice_signals): fix typo
1038 Mon Apr 14 16:25:10 1997 Ian Lance Taylor <ian@cygnus.com>
1040 * gdbserver/Makefile.in (INSTALL): Change install.sh to
1043 Mon Apr 14 11:55:27 1997 Geoffrey Noer <noer@pizza.cygnus.com>
1045 * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
1046 since gcc automatically includes it
1048 Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>
1050 * procfs.c: Substantial (but incomplete) changes to support
1051 sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
1052 struct now has substructs like struct flt_ctl instead of
1053 just a fltset_t and has a ctl_fd, status_fd, as_fd, and
1054 map_fd instead of a single fd. Non-sysv4.2mp procfs models
1055 still have the structs and multiple fds, but don't use the
1056 entire struct and the four fds all point to the same thing.
1057 We use PROCFS_USE_READ_WRITE to decide whether to talk to
1058 procfs with reads/writes or use ioctl instead. We use
1059 HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
1060 multiple fds or not. PROC_NAME_FMT is split out into
1061 CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
1062 STATUS_PROC_NAME_FMT.
1064 (procfs_notice_signals): now a necessary wrapper around
1065 (notice_signals): which are the new guts for noticing signals
1066 (open_proc_file): gets a new flag arg used in sysv4.2mp to
1067 determine whether or not to attempt to open the ctl_fd.
1068 (procfs_read_status): new local function, reads procfs status
1069 (procfs_write_pcwstop): new local function, writes a PCWSTOP
1070 (procfs_write_pckill): new local function, writes a PCKILL
1071 (unconditionally_kill_inferior): remove signo since we now
1072 just call procfs_write_pckill().
1073 (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
1074 (proc_iterate_over_mappings): the whole function is ifdefed
1075 on UNIXWARE to keep things readable.
1077 Expanded the syscall_table to include new potential sysv4.2mp
1078 members. Note that all ifdefs of UNIXWARE should be eliminated
1079 if possible or renamed to describe what's being selected for a
1080 bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
1081 IRIX specific code now also checks it's not UNIXWARE.
1083 * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
1084 HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
1085 * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
1086 "/debug/%d" as PROC_NAME_FMT used to be
1088 Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com)
1090 * mn10300-tdep.c: Almost completely rewritten based on mn10200
1092 * config/mn10300/tm-mn10300.h: Likewise.
1094 Tue Apr 8 10:45:24 1997 Stu Grossman (grossman@critters.cygnus.com)
1096 * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
1097 remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
1098 lousy out-of-date clone of remote.c.
1100 Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
1102 * remote.c: Fix problems realized while showering.
1103 * (hexnumlen): Add prototype. Use max, not min.
1104 * (remote_write_bytes remote_read_bytes): Fix max packet size
1105 calculations to properly account for packet overhead. Also handle
1106 (probably rare) case where remote_register_buf_size isn't set.
1108 * remote.c: Fix doc for `C' and `S' commands to indicate full
1110 * (remote_ops extended_remote_ops remote_desc remote_write_size):
1112 * (remote_fetch_registers remote_write_bytes remote_read_bytes):
1113 Record size of response to fetch registers command, use this to
1114 limit size of memory read and write commands.
1115 * (push_remote_target): New function to make it possible to have
1116 another target switch to the remote target.
1117 * target.h: Add prototype for push_remote_target.
1118 * sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
1119 for hosts which default to unsigned chars (such as SGI's).
1120 * (_initialize_sh_tdep): Don't set remote_write_size. It's now
1121 handled automatically in remote.c.
1123 Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
1125 * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
1126 find_pc_sect_function(), find_pc_sect_partial_function(): new
1127 functions for debugging overlays; pc without section is ambiguous.
1128 * breakpoint.[ch]: add section pointer to breakpoint struct;
1129 add section argument to check_duplicates(); check section as well
1130 as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
1131 breakpoint_thread_match(), bpstat_stop_status()];
1132 add section argument to describe_other_breakpoints();
1133 use INIT_SAL() macro to zero-out new sal structures;
1134 make resolve_sal_pc() fix up the sal's section as well as its pc;
1135 match on section + pc in clear_command() and delete_breakpoint();
1136 account for overlay sections in insert_breakpoints(),
1137 remove_breakpoint() and breakpoint_re_set_one();
1138 all this to support overlays where a PC is not unique.
1139 * exec.c: change xfer_memory() to handle overlay sections.
1140 * findvar.c: change read_var_value() to handle overlay sections.
1141 * frame.h: declaration for block_for_pc_sect() [blockframe.c].
1142 * infcmd.c: jump_command() warns against jumping into an overlay
1143 that's not in memory. Also use INIT_SAL() to initialize sals.
1144 * infrun.c: wait_for_inferior() sets a flag to invalidate cached
1145 overlay state information; Also use INIT_SAL() to init sals.
1146 * m32r-rom.c: modify load routines to use LMA instead of VMA.
1147 * m32r-stub.c: mask exit value down to 8 bits; screen out any
1148 memory read/writes in the range 600000 to a00000, and ff680000
1149 to ff800000 (hangs because nothing is mapped there); fix strcpy().
1150 * maint.c: maintenance command "translate-address" supports overlays.
1151 * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
1152 * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
1153 this constitutes gdb's internal overlay mapping table. Add macro
1154 ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
1155 Add function find_pc_sect_section().
1156 * printcmd.c: modify print_address_symbolic() with overlay smarts;
1157 modify address_info() with overlay smarts; add function sym_info()
1158 to support the INFO SYMBOL command (translate address to symbol(s));
1159 modify disassemble_command() to work on unmapped overlays.
1160 * source.c: use INIT_SAL() to initialize sals.
1161 * symfile.[ch]: change generic_load() to use section's LMA address
1162 instead of VMA address, for overlay sections.
1163 Add numerous functions for finding a PC's section / overlay,
1164 translating between VMA and LMA address ranges, determining if an
1165 overlay section is mapped, etc. Add several user commands for
1166 overlay debugging. Add support for a "generic" form of automatically
1167 reading overlay mapping info from the inferior (based on the default
1168 (simple) overlay manager which Cygnus provides as an example).
1169 * symtab.[ch]: add functions find_pc_sect_symtab(),
1170 find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
1171 for lookup; modify lookup_symbol and decode_line_1() to use them;
1172 modify find_function_start_sal() to account for overlay sections;
1173 add macro INIT_SAL() for initializing struct symtab_and_line.
1174 * target.c: fix a comment in the declaration of target_ops.
1176 Thu Apr 3 10:31:12 1997 Mark Alexander <marka@cygnus.com>
1178 * mips-tdep.c (mips_in_call_stub, mips_in_return_stub,

1189 the above functions.
1190 (INIT_FRAME_PC_FIRST): Change to invoke mips_init_frame_pc.
1191 (mips_init_frame_pc): Declare.
1192 * infrun.c (wait_for_inferior): Use new IGNORE_HELPER_CALL macro
1193 to decide if certain library function calls should be ignored.

1319 on little-endian hosts.
1321 * mdebugread.c (parse_procedure): Adjust address of procedure relative

1323 strings that may precede functions in the text section. Remove
1324 now-useless lowest_pdr_addr from argument list and all calls.
1326 Fri Mar 21 15:36:25 1997 Michael Meissner <meissner@cygnus.com>

1936 * config/mn10300/tm-mn10300.h: fix BREAKPOINT definition.
1938 Tue Jan 14 16:01:06 1997 Geoffrey Noer <noer@cygnus.com>
1940 * mn10300-tdep.c: made a lot more generic, ripping out code
1941 from copied target (no more mn10300_scan_prologue,
1942 init_extra_frame_info, and mn10300_fix_call_dummy calls)
1943 * config/mn10300/tm-mn10300.h: undefine INIT_EXTRA_FRAME_INFO
1944 and INIT_FRAME_PC macros
1946 Thu Jan 9 11:44:40 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
1948 * sparc-tdep.c (sparc_frame_find_saved_regs): Don't use
1949 FP_REGISTER_BYTES to compute offsets into the saved frame,
1950 since it fails for SPARC targets configured without any
1951 FP regs. Instead, use DUMMY_STACK_REG_BUF_SIZE.

1960 * Makefile.in configure configure.in: Remove ENABLE_CLIBS,
1961 ENABLE_OBS, and THREAD_DB_OBS. These are consolidated into LIBS
1963 * configure configure.in: Clean up test cases around thread support.
1965 * configure.tgt (v850-*-*): Include v850ice.o and v850.lib if
1968 * c-valprint.c ch-valprint.c cp-valprint.c eval.c expprint.c
1969 printcmd.c valops.c value.h values.c: Add bfd_section arg to
1970 value_at and value_at_lazy.
1971 * coffread.c dbxread.c elfread.c mdebugread.c minsyms.c symtab.h:
1972 Add bfd_section arg to prim_record_minimal_symbol_and_info.
1973 * corefile.c gdbcore.h printcmd.c valops.c: Use read_memory_section
1974 instead of read_memory. It takes a bfd_section arg.
1975 * coffread.c dbxread.c elfread.c gdb-stabs.h objfiles.h: Remove
1976 unnecessary cast for assignment of struct dbx_symfile_info.
1977 Struct objfile now uses a real pointer instead of PTR for this
1979 * dbxread.c (dbx_symfile_init): Stash bfd section pointers for
1980 text, data and bss into dbx_symfile_info.
1981 * exec.c (xfer_memory): Handle transfers for user-specified
1983 * findvar.c (read_var_value locate_var_value): Copy bfd section
1984 from the symbol to the value.
1985 * gdb-stabs.h: Add section pointers for text, data and bss
1987 * maint.c (translate address command): Add test code for overlay
1988 address translation.
1989 * printcmd.c (do_examine do_one_display): Now takes a bfd section
1991 * (print_formatted x_command): Record current section along with
1992 current address for repeated commands.
1993 * sparc-nat.c (fetch_inferior_registers): Change
1994 target_xfer_memory to target_{read write}_memory to allow changes
1995 to target_xfer_memory interface for section info.
1996 * symmisc.c (dump_msymbols print_symbol): Print section
1997 assocaited with symbol.
1998 * symtab.c (fixup_symbol_section): New routine to
1999 add section info to symbols returned by lookup_symbol.
2000 * symtab.h (struct general_symbol_info): Add bfd section to
2002 * target.c target.h (target_xfer_memory): Add bfd section to
2004 * (target_read_memory_section): New routine to read data from a
2006 * (target_memory_bfd_section): New global variable to pass bfd
2007 section in to targets.
2008 * valarith.c (value_add value_addr value_array): Preserve bfd
2009 section when computing new value.
2010 * value.h (struct value): Add bfd section to values.
2011 * values.c (allocate_value value_copy): Initialize/preserve bfd
2013 * (unpack_double): Clean up _MSC_VER conditionals to remove
2016 * v850ice.c: New module to support communication with NEC's
2018 * config/v850/tm-v850.h (REGISTER_NAMES): Replace sp, gp, fp, and
2019 ep names with rxx names. sp and fp are renamed via a different
2023 Fri Jan 3 14:20:05 1997 Geoffrey Noer <noer@cygnus.com>
2025 * mn10300-tdep.c (mn10300_push_arguments): rewrote,
2026 also removed code elsewhere that made use of RP_REGNUM.
2027 * config/mn10300/tm-mn10300.h: ripped out RP_REGNUM, V0_REGNUM,
2028 ARG0_REGNUM, ARGLAST_REGNUM (all not appropriate for mn10300
2029 arch.), redefined SAVED_PC_AFTER_CALL, EXTRACT_RETURN_VALUE,
2030 EXTRACT_STRUCT_VALUE_ADDRESS, STORE_RETURN_VALUE.
