1018 sim_create_inferior.
1019 (gdbsim_open): Pass endian indicator as arg.
1021 Tue Apr 15 15:31:09 1997 Stan Shebs <shebs@andros.cygnus.com>
1023 * remote.c (get_offsets): Don't use scanf for interpreting
1024 response to qOffsets.
1026 Tue Apr 15 14:51:04 1997 Ian Lance Taylor <ian@cygnus.com>
1028 * gdbserver/Makefile.in (INSTALL_XFORM): Remove.
1029 (INSTALL_XFORM1): Remove.
1030 (install-only): Use $(program_transform_name) directly, rather
1031 than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).

1048 Mon Apr 14 11:55:27 1997 Geoffrey Noer <noer@pizza.cygnus.com>
1050 * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
1051 since gcc automatically includes it
1053 Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>
1055 * procfs.c: Substantial (but incomplete) changes to support
1056 sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
1057 struct now has substructs like struct flt_ctl instead of
1058 just a fltset_t and has a ctl_fd, status_fd, as_fd, and
1059 map_fd instead of a single fd. Non-sysv4.2mp procfs models
1060 still have the structs and multiple fds, but don't use the
1061 entire struct and the four fds all point to the same thing.
1062 We use PROCFS_USE_READ_WRITE to decide whether to talk to
1063 procfs with reads/writes or use ioctl instead. We use
1064 HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
1065 multiple fds or not. PROC_NAME_FMT is split out into
1066 CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
1067 STATUS_PROC_NAME_FMT.
1069 (procfs_notice_signals): now a necessary wrapper around
1070 (notice_signals): which are the new guts for noticing signals
1071 (open_proc_file): gets a new flag arg used in sysv4.2mp to
1072 determine whether or not to attempt to open the ctl_fd.
1073 (procfs_read_status): new local function, reads procfs status
1074 (procfs_write_pcwstop): new local function, writes a PCWSTOP
1075 (procfs_write_pckill): new local function, writes a PCKILL
1076 (unconditionally_kill_inferior): remove signo since we now
1077 just call procfs_write_pckill().
1078 (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
1079 (proc_iterate_over_mappings): the whole function is ifdefed
1080 on UNIXWARE to keep things readable.
1082 Expanded the syscall_table to include new potential sysv4.2mp
1083 members. Note that all ifdefs of UNIXWARE should be eliminated
1084 if possible or renamed to describe what's being selected for a
1085 bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
1086 IRIX specific code now also checks it's not UNIXWARE.
1088 * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
1089 HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
1090 * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
1091 "/debug/%d" as PROC_NAME_FMT used to be
1093 Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com)
1095 * mn10300-tdep.c: Almost completely rewritten based on mn10200
1097 * config/mn10300/tm-mn10300.h: Likewise.
1099 Tue Apr 8 10:45:24 1997 Stu Grossman (grossman@critters.cygnus.com)
1101 * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
1102 remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
1103 lousy out-of-date clone of remote.c.
1105 Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
1107 * remote.c: Fix problems realized while showering.
1108 * (hexnumlen): Add prototype. Use max, not min.
1109 * (remote_write_bytes remote_read_bytes): Fix max packet size
1110 calculations to properly account for packet overhead. Also handle
1111 (probably rare) case where remote_register_buf_size isn't set.
1113 * remote.c: Fix doc for `C' and `S' commands to indicate full
1115 * (remote_ops extended_remote_ops remote_desc remote_write_size):
1117 * (remote_fetch_registers remote_write_bytes remote_read_bytes):
1118 Record size of response to fetch registers command, use this to
1119 limit size of memory read and write commands.
1120 * (push_remote_target): New function to make it possible to have
1121 another target switch to the remote target.
1122 * target.h: Add prototype for push_remote_target.
1123 * sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
1124 for hosts which default to unsigned chars (such as SGI's).
1125 * (_initialize_sh_tdep): Don't set remote_write_size. It's now
1126 handled automatically in remote.c.
1128 Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
1130 * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
1131 find_pc_sect_function(), find_pc_sect_partial_function(): new
1132 functions for debugging overlays; pc without section is ambiguous.
1133 * breakpoint.[ch]: add section pointer to breakpoint struct;
1134 add section argument to check_duplicates(); check section as well
1135 as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
1136 breakpoint_thread_match(), bpstat_stop_status()];
1137 add section argument to describe_other_breakpoints();
1138 use INIT_SAL() macro to zero-out new sal structures;
1139 make resolve_sal_pc() fix up the sal's section as well as its pc;
1140 match on section + pc in clear_command() and delete_breakpoint();
1141 account for overlay sections in insert_breakpoints(),
1142 remove_breakpoint() and breakpoint_re_set_one();
1143 all this to support overlays where a PC is not unique.
1144 * exec.c: change xfer_memory() to handle overlay sections.
1145 * findvar.c: change read_var_value() to handle overlay sections.
1146 * frame.h: declaration for block_for_pc_sect() [blockframe.c].
1147 * infcmd.c: jump_command() warns against jumping into an overlay
1148 that's not in memory. Also use INIT_SAL() to initialize sals.
1149 * infrun.c: wait_for_inferior() sets a flag to invalidate cached
1150 overlay state information; Also use INIT_SAL() to init sals.
1151 * m32r-rom.c: modify load routines to use LMA instead of VMA.
1152 * m32r-stub.c: mask exit value down to 8 bits; screen out any
1153 memory read/writes in the range 600000 to a00000, and ff680000
1154 to ff800000 (hangs because nothing is mapped there); fix strcpy().
1155 * maint.c: maintenance command "translate-address" supports overlays.
1156 * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
1157 * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
1158 this constitutes gdb's internal overlay mapping table. Add macro
1159 ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
1160 Add function find_pc_sect_section().
1161 * printcmd.c: modify print_address_symbolic() with overlay smarts;
1162 modify address_info() with overlay smarts; add function sym_info()
1163 to support the INFO SYMBOL command (translate address to symbol(s));
1164 modify disassemble_command() to work on unmapped overlays.
1165 * source.c: use INIT_SAL() to initialize sals.
1166 * symfile.[ch]: change generic_load() to use section's LMA address
1167 instead of VMA address, for overlay sections.
1168 Add numerous functions for finding a PC's section / overlay,
1169 translating between VMA and LMA address ranges, determining if an
1170 overlay section is mapped, etc. Add several user commands for
1171 overlay debugging. Add support for a "generic" form of automatically
1172 reading overlay mapping info from the inferior (based on the default
1173 (simple) overlay manager which Cygnus provides as an example).
1174 * symtab.[ch]: add functions find_pc_sect_symtab(),
1175 find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
1176 for lookup; modify lookup_symbol and decode_line_1() to use them;
1177 modify find_function_start_sal() to account for overlay sections;
1178 add macro INIT_SAL() for initializing struct symtab_and_line.
1179 * target.c: fix a comment in the declaration of target_ops.
1181 Thu Apr 3 10:31:12 1997 Mark Alexander <marka@cygnus.com>
1183 * mips-tdep.c (mips_in_call_stub, mips_in_return_stub,

1194 the above functions.
1195 (INIT_FRAME_PC_FIRST): Change to invoke mips_init_frame_pc.
1196 (mips_init_frame_pc): Declare.
1197 * infrun.c (wait_for_inferior): Use new IGNORE_HELPER_CALL macro
1198 to decide if certain library function calls should be ignored.

1328 strings that may precede functions in the text section. Remove
1329 now-useless lowest_pdr_addr from argument list and all calls.
1331 Fri Mar 21 15:36:25 1997 Michael Meissner <meissner@cygnus.com>

1936 with a zero PC as frameless to improve backtraces from core dumps
1937 caused by dereferencing a NULL function pointer.

1945 * mn10300-tdep.c: made a lot more generic, ripping out code
1946 from copied target (no more mn10300_scan_prologue,
1947 init_extra_frame_info, and mn10300_fix_call_dummy calls)
1948 * config/mn10300/tm-mn10300.h: undefine INIT_EXTRA_FRAME_INFO
1949 and INIT_FRAME_PC macros
1951 Thu Jan 9 11:44:40 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
1953 * sparc-tdep.c (sparc_frame_find_saved_regs): Don't use
1954 FP_REGISTER_BYTES to compute offsets into the saved frame,
1955 since it fails for SPARC targets configured without any
1956 FP regs. Instead, use DUMMY_STACK_REG_BUF_SIZE.

1965 * Makefile.in configure configure.in: Remove ENABLE_CLIBS,
1966 ENABLE_OBS, and THREAD_DB_OBS. These are consolidated into LIBS
1968 * configure configure.in: Clean up test cases around thread support.
1970 * configure.tgt (v850-*-*): Include v850ice.o and v850.lib if
1973 * c-valprint.c ch-valprint.c cp-valprint.c eval.c expprint.c
1974 printcmd.c valops.c value.h values.c: Add bfd_section arg to
1975 value_at and value_at_lazy.
1976 * coffread.c dbxread.c elfread.c mdebugread.c minsyms.c symtab.h:
1977 Add bfd_section arg to prim_record_minimal_symbol_and_info.
1978 * corefile.c gdbcore.h printcmd.c valops.c: Use read_memory_section
1979 instead of read_memory. It takes a bfd_section arg.
1980 * coffread.c dbxread.c elfread.c gdb-stabs.h objfiles.h: Remove
1981 unnecessary cast for assignment of struct dbx_symfile_info.
1982 Struct objfile now uses a real pointer instead of PTR for this
1984 * dbxread.c (dbx_symfile_init): Stash bfd section pointers for
1985 text, data and bss into dbx_symfile_info.
1986 * exec.c (xfer_memory): Handle transfers for user-specified
1988 * findvar.c (read_var_value locate_var_value): Copy bfd section
1989 from the symbol to the value.
1990 * gdb-stabs.h: Add section pointers for text, data and bss
1992 * maint.c (translate address command): Add test code for overlay
1993 address translation.
1994 * printcmd.c (do_examine do_one_display): Now takes a bfd section
1996 * (print_formatted x_command): Record current section along with
1997 current address for repeated commands.
1998 * sparc-nat.c (fetch_inferior_registers): Change
1999 target_xfer_memory to target_{read write}_memory to allow changes
2000 to target_xfer_memory interface for section info.
2001 * symmisc.c (dump_msymbols print_symbol): Print section
2002 assocaited with symbol.
2003 * symtab.c (fixup_symbol_section): New routine to
2004 add section info to symbols returned by lookup_symbol.
2005 * symtab.h (struct general_symbol_info): Add bfd section to
2007 * target.c target.h (target_xfer_memory): Add bfd section to
2009 * (target_read_memory_section): New routine to read data from a
2011 * (target_memory_bfd_section): New global variable to pass bfd
2012 section in to targets.
2013 * valarith.c (value_add value_addr value_array): Preserve bfd
2014 section when computing new value.
2015 * value.h (struct value): Add bfd section to values.
2016 * values.c (allocate_value value_copy): Initialize/preserve bfd
2018 * (unpack_double): Clean up _MSC_VER conditionals to remove
2021 * v850ice.c: New module to support communication with NEC's
2023 * config/v850/tm-v850.h (REGISTER_NAMES): Replace sp, gp, fp, and
2024 ep names with rxx names. sp and fp are renamed via a different

2030 * mn10300-tdep.c (mn10300_push_arguments): rewrote,
2031 also removed code elsewhere that made use of RP_REGNUM.
2032 * config/mn10300/tm-mn10300.h: ripped out RP_REGNUM, V0_REGNUM,
2033 ARG0_REGNUM, ARGLAST_REGNUM (all not appropriate for mn10300
2034 arch.), redefined SAVED_PC_AFTER_CALL, EXTRACT_RETURN_VALUE,
2035 EXTRACT_STRUCT_VALUE_ADDRESS, STORE_RETURN_VALUE.
