6 add (temporary) logging commands to help debugging,
7 (ocd_open): if "target ocd wiggler lpt" then use special
8 ser-ocd.c serial interface which communicates with Wigglers.dll,
9 otherwise ("target ocd <foo>") do as we did before

35 (On Chip Debugging). Wiggler is the parallel port box controlled
36 by Wigglers.dll. The faster target box from Macraigor Systems
42 Replace all instances of "wiggler_" with "ocd_" and change most other
43 instances of "wiggler" to "ocd" or "ocd device" depending on context.

1014 * gdbserver/Makefile.in (INSTALL_XFORM): Remove.
1015 (INSTALL_XFORM1): Remove.
1016 (install-only): Use $(program_transform_name) directly, rather
1017 than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).
1018 (uninstall): Transform name.
1020 Mon Apr 14 17:06:27 1997 Mark Alexander <marka@cygnus.com>
1022 * remote-mips.c (mips_load): Ensure that PC gets updated
1023 after a load on LSI target.
1025 Mon Apr 14 15:54:51 1997 Geoffrey Noer <noer@pizza.cygnus.com>
1027 * procfs.c (notice_signals): fix typo
1029 Mon Apr 14 16:25:10 1997 Ian Lance Taylor <ian@cygnus.com>
1031 * gdbserver/Makefile.in (INSTALL): Change install.sh to
1034 Mon Apr 14 11:55:27 1997 Geoffrey Noer <noer@pizza.cygnus.com>
1036 * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
1037 since gcc automatically includes it
1039 Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>
1041 * procfs.c: Substantial (but incomplete) changes to support
1042 sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
1043 struct now has substructs like struct flt_ctl instead of
1044 just a fltset_t and has a ctl_fd, status_fd, as_fd, and
1045 map_fd instead of a single fd. Non-sysv4.2mp procfs models
1046 still have the structs and multiple fds, but don't use the
1047 entire struct and the four fds all point to the same thing.
1048 We use PROCFS_USE_READ_WRITE to decide whether to talk to
1049 procfs with reads/writes or use ioctl instead. We use
1050 HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
1051 multiple fds or not. PROC_NAME_FMT is split out into
1052 CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
1053 STATUS_PROC_NAME_FMT.
1055 (procfs_notice_signals): now a necessary wrapper around
1056 (notice_signals): which are the new guts for noticing signals
1057 (open_proc_file): gets a new flag arg used in sysv4.2mp to
1058 determine whether or not to attempt to open the ctl_fd.
1059 (procfs_read_status): new local function, reads procfs status
1060 (procfs_write_pcwstop): new local function, writes a PCWSTOP
1061 (procfs_write_pckill): new local function, writes a PCKILL
1062 (unconditionally_kill_inferior): remove signo since we now
1063 just call procfs_write_pckill().
1064 (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
1065 (proc_iterate_over_mappings): the whole function is ifdefed
1066 on UNIXWARE to keep things readable.
1068 Expanded the syscall_table to include new potential sysv4.2mp
1069 members. Note that all ifdefs of UNIXWARE should be eliminated
1070 if possible or renamed to describe what's being selected for a
1071 bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
1072 IRIX specific code now also checks it's not UNIXWARE.
1074 * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
1075 HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
1076 * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
1077 "/debug/%d" as PROC_NAME_FMT used to be
1079 Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com)
1081 * mn10300-tdep.c: Almost completely rewritten based on mn10200
1083 * config/mn10300/tm-mn10300.h: Likewise.
1085 Tue Apr 8 10:45:24 1997 Stu Grossman (grossman@critters.cygnus.com)
1087 * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
1088 remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
1089 lousy out-of-date clone of remote.c.
1091 Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
1093 * remote.c: Fix problems realized while showering.
1094 * (hexnumlen): Add prototype. Use max, not min.
1095 * (remote_write_bytes remote_read_bytes): Fix max packet size
1096 calculations to properly account for packet overhead. Also handle
1097 (probably rare) case where remote_register_buf_size isn't set.
1099 * remote.c: Fix doc for `C' and `S' commands to indicate full
1101 * (remote_ops extended_remote_ops remote_desc remote_write_size):
1103 * (remote_fetch_registers remote_write_bytes remote_read_bytes):
1104 Record size of response to fetch registers command, use this to
1105 limit size of memory read and write commands.
1106 * (push_remote_target): New function to make it possible to have
1107 another target switch to the remote target.
1108 * target.h: Add prototype for push_remote_target.
1109 * sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
1110 for hosts which default to unsigned chars (such as SGI's).
1111 * (_initialize_sh_tdep): Don't set remote_write_size. It's now
1112 handled automatically in remote.c.
1114 Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
1116 * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
1117 find_pc_sect_function(), find_pc_sect_partial_function(): new
1118 functions for debugging overlays; pc without section is ambiguous.
1119 * breakpoint.[ch]: add section pointer to breakpoint struct;
1120 add section argument to check_duplicates(); check section as well
1121 as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
1122 breakpoint_thread_match(), bpstat_stop_status()];
1123 add section argument to describe_other_breakpoints();
1124 use INIT_SAL() macro to zero-out new sal structures;
1125 make resolve_sal_pc() fix up the sal's section as well as its pc;
1126 match on section + pc in clear_command() and delete_breakpoint();
1127 account for overlay sections in insert_breakpoints(),
1128 remove_breakpoint() and breakpoint_re_set_one();
1129 all this to support overlays where a PC is not unique.
1130 * exec.c: change xfer_memory() to handle overlay sections.
1131 * findvar.c: change read_var_value() to handle overlay sections.
1132 * frame.h: declaration for block_for_pc_sect() [blockframe.c].
1133 * infcmd.c: jump_command() warns against jumping into an overlay
1134 that's not in memory. Also use INIT_SAL() to initialize sals.
1135 * infrun.c: wait_for_inferior() sets a flag to invalidate cached
1136 overlay state information; Also use INIT_SAL() to init sals.
1137 * m32r-rom.c: modify load routines to use LMA instead of VMA.
1138 * m32r-stub.c: mask exit value down to 8 bits; screen out any
1139 memory read/writes in the range 600000 to a00000, and ff680000
1140 to ff800000 (hangs because nothing is mapped there); fix strcpy().
1141 * maint.c: maintenance command "translate-address" supports overlays.
1142 * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
1143 * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
1144 this constitutes gdb's internal overlay mapping table. Add macro
1145 ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
1146 Add function find_pc_sect_section().
1147 * printcmd.c: modify print_address_symbolic() with overlay smarts;
1148 modify address_info() with overlay smarts; add function sym_info()
1149 to support the INFO SYMBOL command (translate address to symbol(s));
1150 modify disassemble_command() to work on unmapped overlays.
1151 * source.c: use INIT_SAL() to initialize sals.
1152 * symfile.[ch]: change generic_load() to use section's LMA address
1153 instead of VMA address, for overlay sections.
1154 Add numerous functions for finding a PC's section / overlay,
1155 translating between VMA and LMA address ranges, determining if an
1156 overlay section is mapped, etc. Add several user commands for
1157 overlay debugging. Add support for a "generic" form of automatically
1158 reading overlay mapping info from the inferior (based on the default
1159 (simple) overlay manager which Cygnus provides as an example).
1160 * symtab.[ch]: add functions find_pc_sect_symtab(),
1161 find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
1162 for lookup; modify lookup_symbol and decode_line_1() to use them;
1163 modify find_function_start_sal() to account for overlay sections;
1164 add macro INIT_SAL() for initializing struct symtab_and_line.
1165 * target.c: fix a comment in the declaration of target_ops.
1167 Thu Apr 3 10:31:12 1997 Mark Alexander <marka@cygnus.com>
1169 * mips-tdep.c (mips_in_call_stub, mips_in_return_stub,

1180 the above functions.
1181 (INIT_FRAME_PC_FIRST): Change to invoke mips_init_frame_pc.
1182 (mips_init_frame_pc): Declare.
1183 * infrun.c (wait_for_inferior): Use new IGNORE_HELPER_CALL macro
1184 to decide if certain library function calls should be ignored.

1315 now-useless lowest_pdr_addr from argument list and all calls.
1317 Fri Mar 21 15:36:25 1997 Michael Meissner <meissner@cygnus.com>

1932 from copied target (no more mn10300_scan_prologue,
1933 init_extra_frame_info, and mn10300_fix_call_dummy calls)
1934 * config/mn10300/tm-mn10300.h: undefine INIT_EXTRA_FRAME_INFO
1935 and INIT_FRAME_PC macros
1937 Thu Jan 9 11:44:40 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
1939 * sparc-tdep.c (sparc_frame_find_saved_regs): Don't use
1940 FP_REGISTER_BYTES to compute offsets into the saved frame,
1941 since it fails for SPARC targets configured without any
1942 FP regs. Instead, use DUMMY_STACK_REG_BUF_SIZE.

1951 * Makefile.in configure configure.in: Remove ENABLE_CLIBS,
1952 ENABLE_OBS, and THREAD_DB_OBS. These are consolidated into LIBS
1954 * configure configure.in: Clean up test cases around thread support.
1956 * configure.tgt (v850-*-*): Include v850ice.o and v850.lib if
1959 * c-valprint.c ch-valprint.c cp-valprint.c eval.c expprint.c
1960 printcmd.c valops.c value.h values.c: Add bfd_section arg to
1961 value_at and value_at_lazy.
1962 * coffread.c dbxread.c elfread.c mdebugread.c minsyms.c symtab.h:
1963 Add bfd_section arg to prim_record_minimal_symbol_and_info.
1964 * corefile.c gdbcore.h printcmd.c valops.c: Use read_memory_section
1965 instead of read_memory. It takes a bfd_section arg.
1966 * coffread.c dbxread.c elfread.c gdb-stabs.h objfiles.h: Remove
1967 unnecessary cast for assignment of struct dbx_symfile_info.
1968 Struct objfile now uses a real pointer instead of PTR for this
1970 * dbxread.c (dbx_symfile_init): Stash bfd section pointers for
1971 text, data and bss into dbx_symfile_info.
1972 * exec.c (xfer_memory): Handle transfers for user-specified
1974 * findvar.c (read_var_value locate_var_value): Copy bfd section
1975 from the symbol to the value.
1976 * gdb-stabs.h: Add section pointers for text, data and bss
1978 * maint.c (translate address command): Add test code for overlay
1979 address translation.
1980 * printcmd.c (do_examine do_one_display): Now takes a bfd section
1982 * (print_formatted x_command): Record current section along with
1983 current address for repeated commands.
1984 * sparc-nat.c (fetch_inferior_registers): Change
1985 target_xfer_memory to target_{read write}_memory to allow changes
1986 to target_xfer_memory interface for section info.
1987 * symmisc.c (dump_msymbols print_symbol): Print section
1988 assocaited with symbol.
1989 * symtab.c (fixup_symbol_section): New routine to
1990 add section info to symbols returned by lookup_symbol.
1991 * symtab.h (struct general_symbol_info): Add bfd section to
1993 * target.c target.h (target_xfer_memory): Add bfd section to
1995 * (target_read_memory_section): New routine to read data from a
1997 * (target_memory_bfd_section): New global variable to pass bfd
1998 section in to targets.
1999 * valarith.c (value_add value_addr value_array): Preserve bfd
2000 section when computing new value.
2001 * value.h (struct value): Add bfd section to values.
2002 * values.c (allocate_value value_copy): Initialize/preserve bfd
2004 * (unpack_double): Clean up _MSC_VER conditionals to remove
2007 * v850ice.c: New module to support communication with NEC's
2009 * config/v850/tm-v850.h (REGISTER_NAMES): Replace sp, gp, fp, and
2010 ep names with rxx names. sp and fp are renamed via a different
2014 Fri Jan 3 14:20:05 1997 Geoffrey Noer <noer@cygnus.com>
2016 * mn10300-tdep.c (mn10300_push_arguments): rewrote,
2017 also removed code elsewhere that made use of RP_REGNUM.
2018 * config/mn10300/tm-mn10300.h: ripped out RP_REGNUM, V0_REGNUM,
2019 ARG0_REGNUM, ARGLAST_REGNUM (all not appropriate for mn10300
2020 arch.), redefined SAVED_PC_AFTER_CALL, EXTRACT_RETURN_VALUE,
2021 EXTRACT_STRUCT_VALUE_ADDRESS, STORE_RETURN_VALUE.
