927 global symbols before starting the expensive minimal symbol table
929 (scan_file_globals): Now calls scan_file_globals_1 for the passed
930 objfile and eventually for the runtime common objfile. Complains
931 about any unresolved global symbols and removes them from the
932 global symbol chain to avoid dangling pointers into the symbol
933 table if the symbol table is reread.

937 * Makefile.in (install_only uninstall): Indent for clarity.
939 * core.c (dis_asm_read_memory): Add call to
940 dis_asm_read_memory_hook to provide alternate way for disassembler
943 * defs.h: Protect from multiple inclusion. Add decl for
944 dis_asm_read_memory_hook.
946 * top.c: Make window startup be the default.
947 * Add dis_asm_read_memory_hook.
950 * gdbtk.c (finish_saving_output): Don't do anything if not saving
952 * (breakpoint_notify): Don't send null filename to tcl.
953 * (gdb_eval): New tcl command to eval an expression.
954 * (gdb_disassemble): New tcl command to do disassembly. This
955 allows tcl code to choose between exec file and target memeory,
956 and can also do mixed source and assembly.
957 * (gdbtk_init): Move reading of gdbtk.tcl to the end to make sure
958 that more of the environment is set up. Also, create link between
959 gdb and tcl vars disassemble{-_}from{-_}exec.
961 * gdbtk.tcl: New expression window support.
962 * Make assembly window be 80 columns wide.
963 * Use new disassembly method. Add menu items to select
964 disassembly from exec file or target.
965 * Change View menubar item to Options.
967 * Get rid of Stack, Breakpoints, Signals, and Variables Windows,
968 since they don't exist yet.
970 * Pop up a copyright window on startup.
973 Thu Jan 5 01:16:40 1995 Jeff Law (law@snake.cs.utah.edu)
975 * stabsread.c (define_symbol): Handle `a' symbol type used for
976 reference parameter passed in a register.
979 Wed Jan 4 19:49:10 1995 Stan Shebs <shebs@andros.cygnus.com>
981 * gdbtk.tcl (build_framework): Add standard commands menu, more
982 windows to standard windows menu.
983 (not_implemented_yet): Clarify message.
986 Wed Jan 4 12:27:29 1995 Kung Hsu <kung@mexican.cygnus.com>
988 * defs.h: move include tm.h up, so that the type LONGEST can
989 also based on the target requirement to determine. In this case
992 * remote-os9k.c (rombug_open): catch exception e in rombug.
993 * remote-os9k.c (rombug_wait): print message before register display
996 Wed Jan 4 09:18:27 1995 Jim Kingdon (kingdon@lioth.cygnus.com)
998 * top.c (locate_arg): Call strchr not index.
1000 Tue Jan 3 16:52:03 1995 Per Bothner <bothner@kalessin.cygnus.com>
1002 * ch-exp.y (literal): Recognize NULL.
1003 (tuple): Parse simple unlabelled tuples.
1004 * eval.c (evaluate_subexp case OP_ARRAY): Use expect_type to
1005 evaluate brace-initializer-expressions depending on context.
1006 (evaluate_subexp case UNOP_CAST): Pass the target type as
1007 expected type when evaluating the expression.
1009 * ch-typeprint.c (chill_type_print_base): Get names of PTR and
1010 BOOL from TYPE_NAME.
1011 * ch-valprint.c (chill_print_type_scalar): New function, to handle
1012 TYPE_CODE_RANGE better than print_type_scalar does.
1013 (chill_val_print_array_elements): Use above new function.
1015 Mon Jan 2 15:02:51 1995 Stan Shebs <shebs@andros.cygnus.com>
1017 * remote-udi.c (udi_load): Tell symbol_file_add that the
1018 program being loaded is the main program.
