1985 since gcc automatically includes it
1987 Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>
1989 * procfs.c: Substantial (but incomplete) changes to support
1990 sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
1991 struct now has substructs like struct flt_ctl instead of
1992 just a fltset_t and has a ctl_fd, status_fd, as_fd, and
1993 map_fd instead of a single fd. Non-sysv4.2mp procfs models
1994 still have the structs and multiple fds, but don't use the
1995 entire struct and the four fds all point to the same thing.
1996 We use PROCFS_USE_READ_WRITE to decide whether to talk to
1997 procfs with reads/writes or use ioctl instead. We use
1998 HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
1999 multiple fds or not. PROC_NAME_FMT is split out into
2000 CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
2001 STATUS_PROC_NAME_FMT.
2003 (procfs_notice_signals): now a necessary wrapper around
2004 (notice_signals): which are the new guts for noticing signals
2005 (open_proc_file): gets a new flag arg used in sysv4.2mp to
2006 determine whether or not to attempt to open the ctl_fd.
2007 (procfs_read_status): new local function, reads procfs status
2008 (procfs_write_pcwstop): new local function, writes a PCWSTOP
2009 (procfs_write_pckill): new local function, writes a PCKILL
2010 (unconditionally_kill_inferior): remove signo since we now
2011 just call procfs_write_pckill().
2012 (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
2013 (proc_iterate_over_mappings): the whole function is ifdefed
2014 on UNIXWARE to keep things readable.
2016 Expanded the syscall_table to include new potential sysv4.2mp
2017 members. Note that all ifdefs of UNIXWARE should be eliminated
2018 if possible or renamed to describe what's being selected for a
2019 bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
2020 IRIX specific code now also checks it's not UNIXWARE.
2022 * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
2023 HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
2024 * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
2025 "/debug/%d" as PROC_NAME_FMT used to be
2027 Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com)
2029 * mn10300-tdep.c: Almost completely rewritten based on mn10200
2031 * config/mn10300/tm-mn10300.h: Likewise.
2033 Tue Apr 8 10:45:24 1997 Stu Grossman (grossman@critters.cygnus.com)
2035 * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
2036 remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
2037 lousy out-of-date clone of remote.c.
2039 Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
2041 * remote.c: Fix problems realized while showering.
2042 * (hexnumlen): Add prototype. Use max, not min.
2043 * (remote_write_bytes remote_read_bytes): Fix max packet size
2044 calculations to properly account for packet overhead. Also handle
2045 (probably rare) case where remote_register_buf_size isn't set.
2047 * remote.c: Fix doc for `C' and `S' commands to indicate full
2049 * (remote_ops extended_remote_ops remote_desc remote_write_size):
2051 * (remote_fetch_registers remote_write_bytes remote_read_bytes):
2052 Record size of response to fetch registers command, use this to
2053 limit size of memory read and write commands.
2054 * (push_remote_target): New function to make it possible to have
2055 another target switch to the remote target.
2056 * target.h: Add prototype for push_remote_target.
2057 * sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
2058 for hosts which default to unsigned chars (such as SGI's).
2059 * (_initialize_sh_tdep): Don't set remote_write_size. It's now
2060 handled automatically in remote.c.
2062 Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
2064 * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
2065 find_pc_sect_function(), find_pc_sect_partial_function(): new
2066 functions for debugging overlays; pc without section is ambiguous.
2067 * breakpoint.[ch]: add section pointer to breakpoint struct;
2068 add section argument to check_duplicates(); check section as well
2069 as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
2070 breakpoint_thread_match(), bpstat_stop_status()];
2071 add section argument to describe_other_breakpoints();
2072 use INIT_SAL() macro to zero-out new sal structures;
2073 make resolve_sal_pc() fix up the sal's section as well as its pc;
2074 match on section + pc in clear_command() and delete_breakpoint();
2075 account for overlay sections in insert_breakpoints(),
2076 remove_breakpoint() and breakpoint_re_set_one();
2077 all this to support overlays where a PC is not unique.
2078 * exec.c: change xfer_memory() to handle overlay sections.
2079 * findvar.c: change read_var_value() to handle overlay sections.
2080 * frame.h: declaration for block_for_pc_sect() [blockframe.c].
2081 * infcmd.c: jump_command() warns against jumping into an overlay
2082 that's not in memory. Also use INIT_SAL() to initialize sals.
2083 * infrun.c: wait_for_inferior() sets a flag to invalidate cached
2084 overlay state information; Also use INIT_SAL() to init sals.
2085 * m32r-rom.c: modify load routines to use LMA instead of VMA.
2086 * m32r-stub.c: mask exit value down to 8 bits; screen out any
2087 memory read/writes in the range 600000 to a00000, and ff680000
2088 to ff800000 (hangs because nothing is mapped there); fix strcpy().
2089 * maint.c: maintenance command "translate-address" supports overlays.
2090 * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
2091 * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
2092 this constitutes gdb's internal overlay mapping table. Add macro
2093 ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
2094 Add function find_pc_sect_section().
2095 * printcmd.c: modify print_address_symbolic() with overlay smarts;
2096 modify address_info() with overlay smarts; add function sym_info()
2097 to support the INFO SYMBOL command (translate address to symbol(s));
2098 modify disassemble_command() to work on unmapped overlays.
2099 * source.c: use INIT_SAL() to initialize sals.
2100 * symfile.[ch]: change generic_load() to use section's LMA address
2101 instead of VMA address, for overlay sections.
2102 Add numerous functions for finding a PC's section / overlay,
2103 translating between VMA and LMA address ranges, determining if an
2104 overlay section is mapped, etc. Add several user commands for
2105 overlay debugging. Add support for a "generic" form of automatically
2106 reading overlay mapping info from the inferior (based on the default
2107 (simple) overlay manager which Cygnus provides as an example).
2108 * symtab.[ch]: add functions find_pc_sect_symtab(),
2109 find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
2110 for lookup; modify lookup_symbol and decode_line_1() to use them;
2111 modify find_function_start_sal() to account for overlay sections;
2112 add macro INIT_SAL() for initializing struct symtab_and_line.
2113 * target.c: fix a comment in the declaration of target_ops.
2115 Thu Apr 3 10:31:12 1997 Mark Alexander <marka@cygnus.com>
2117 * mips-tdep.c (mips_in_call_stub, mips_in_return_stub,

2804 * blockframe.c (frameless_look_for_prologue): Mark frames
2805 with a zero PC as frameless to improve backtraces from core dumps
2806 caused by dereferencing a NULL function pointer.

2814 * mn10300-tdep.c: made a lot more generic, ripping out code
2815 from copied target (no more mn10300_scan_prologue,
2816 init_extra_frame_info, and mn10300_fix_call_dummy calls)
2817 * config/mn10300/tm-mn10300.h: undefine INIT_EXTRA_FRAME_INFO
2818 and INIT_FRAME_PC macros
2820 Thu Jan 9 11:44:40 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
2822 * sparc-tdep.c (sparc_frame_find_saved_regs): Don't use
2823 FP_REGISTER_BYTES to compute offsets into the saved frame,
2824 since it fails for SPARC targets configured without any
2825 FP regs. Instead, use DUMMY_STACK_REG_BUF_SIZE.
2827 Mon Jan 6 11:15:14 1997 Stu Grossman (grossman@critters.cygnus.com)
2829 * symtab.c (fixup_symbol_section): Handle NULL symbols without

2834 * Makefile.in configure configure.in: Remove ENABLE_CLIBS,
2835 ENABLE_OBS, and THREAD_DB_OBS. These are consolidated into LIBS
2837 * configure configure.in: Clean up test cases around thread support.
2838 * configure.tgt (v850-*-*): Include v850ice.o and v850.lib if
2840 * c-valprint.c ch-valprint.c cp-valprint.c eval.c expprint.c
2841 printcmd.c valops.c value.h values.c: Add bfd_section arg to
2842 value_at and value_at_lazy.
2843 * coffread.c dbxread.c elfread.c mdebugread.c minsyms.c symtab.h:
2844 Add bfd_section arg to prim_record_minimal_symbol_and_info.
2845 * corefile.c gdbcore.h printcmd.c valops.c: Use read_memory_section
2846 instead of read_memory. It takes a bfd_section arg.
2847 * coffread.c dbxread.c elfread.c gdb-stabs.h objfiles.h: Remove
2848 unnecessary cast for assignment of struct dbx_symfile_info.
2849 Struct objfile now uses a real pointer instead of PTR for this
2851 * dbxread.c (dbx_symfile_init): Stash bfd section pointers for
2852 text, data and bss into dbx_symfile_info.
2853 * exec.c (xfer_memory): Handle transfers for user-specified

2859 * maint.c (translate address command): Add test code for overlay
2860 address translation.
2861 * printcmd.c (do_examine do_one_display): Now takes a bfd section
2863 * (print_formatted x_command): Record current section along with
2864 current address for repeated commands.
2865 * sparc-nat.c (fetch_inferior_registers): Change
2866 target_xfer_memory to target_{read write}_memory to allow changes
2867 to target_xfer_memory interface for section info.
2868 * symmisc.c (dump_msymbols print_symbol): Print section
2869 assocaited with symbol.
2870 * symtab.c (fixup_symbol_section): New routine to
2871 add section info to symbols returned by lookup_symbol.
2872 * symtab.h (struct general_symbol_info): Add bfd section to
2874 * target.c target.h (target_xfer_memory): Add bfd section to
2876 * (target_read_memory_section): New routine to read data from a
2878 * (target_memory_bfd_section): New global variable to pass bfd
2879 section in to targets.
2880 * valarith.c (value_add value_addr value_array): Preserve bfd
2881 section when computing new value.
2882 * value.h (struct value): Add bfd section to values.
2883 * values.c (allocate_value value_copy): Initialize/preserve bfd
2885 * (unpack_double): Clean up _MSC_VER conditionals to remove
2887 * v850ice.c: New module to support communication with NEC's
2889 * config/v850/tm-v850.h (REGISTER_NAMES): Replace sp, gp, fp, and
2890 ep names with rxx names. sp and fp are renamed via a different

2895 * mn10300-tdep.c (mn10300_push_arguments): rewrote,
2896 also removed code elsewhere that made use of RP_REGNUM.
2897 * config/mn10300/tm-mn10300.h: ripped out RP_REGNUM, V0_REGNUM,
2898 ARG0_REGNUM, ARGLAST_REGNUM (all not appropriate for mn10300
2899 arch.), redefined SAVED_PC_AFTER_CALL, EXTRACT_RETURN_VALUE,
2900 EXTRACT_STRUCT_VALUE_ADDRESS, STORE_RETURN_VALUE.
