FIXME. + * i386-pinsn.c: Move #includes to top, remove useless ones. + * i386-tdep.c: Don't bother including <.../reg.h> since we + don't use it (and it doesn't exist on host systems). + + * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf. + Convert negative numbers properly. + (ieee_test): Make numbers really random; fix format arg. + + * infcmd.c (attach_command, detach_command): Don't repeat on CR. + * core.c (core_detach): Unpush core_ops, which might not be on + top. We used to just pop the top, which broke things. Don't + need dont_repeat() any more. + (core_file_command): Psst! Don't repeat it. + * remote-nindy.c (nindy_detach): Don't need dont_repeat() now. + * expprint.c (print_subexp): Avoid switch fallthru on + BINOP_ASSIGN_MODIFY, so we can print += and such. + * frame.h: Fix typo. + * inflow.c (kill_command): After killing inferior, print our + current frame in the core file, if we have one. + (generic_mourn_inferior): When inferior dies, either select + the current frame (in the new target, e.g. core file), or + set both the current and selected frames to NULL. + + Changes from Peter Schauer. + + * infptrace.c: Avoid <sys/ptrace.h> on USG. + + * Make all file names fit in 14 characters (sigh and damn!): + mv hp300hpux-xdep.c hp300ux-xdep.c + mv symmetry-xdep.c symm-xdep.c + mv symmetry-tdep.c symm-tdep.c + mv convex-opcode.h convx-opcode.h + mv tm-vxworks960.h tm-vx960.h + mv tm-vxworks68.h tm-vx68.h + mv Makefile.srcdir Makefile.sdir + mv gdb-int.texinfo gdbint.texinfo + mv remote-sa.m68k.shar rem-m68k.shar + mv remote-multi.shar rem-multi.shar + * Makefile.dist, README, config.gdb, convex-pinsn.c, + tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68, + xconfig/hp300hpux, xconfig/symmetry: Change names to shorter + names. + + * command.c (user_info_1, user_info): New command for listing + the user-defined commands. + +Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com) + + * dbxread.c (really_free_pendings): Clear file_symbols + and global_symbols after freeing them; otherwise, running + this function twice (if it appears twice on the cleanup + chain), we try to free things twice. + + * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr + based on text_addr (the address of text in core), not on addr (the + offset between text in the .o file and in core). This change + is from Peter Schauer. + + * main.c: Define ALL_CLEANUPS as a cast of zero. + (return_to_top_level): Use it. + (main): Do all cleanups after each command run as part + of the gdb startup sequence. Also do all cleanups before + entering the command loop, and every time we exit the command + loop and reenter. Before, the cleanups from the startup sequence + were being left undone until the first error! + (command_loop): Rename do_nothing cleanup to command_loop_marker + so we can see it easily when examining the cleanup chain. + (init_signals): Add another do_nothing for signal handling. + (quit_command): Only try to kill target if it has execution. + Problems in the target stack got us into a state where + inferior_pid was nonzero but none of the targets had execution. + In this state you couldn't exit gdb. + + * dbxread.c: Two changes from Peter Schauer. + (echo_command): Fflush output after an echo command. + (show_history): Pass all args to cmd_show_list. + + * utils.c (init_malloc): Call mtrace to turn on tracing + if the environment variable MALLOC_TRACE is set to a file name. + * mtrace.c: Add source file which provides a log of every malloc, + free, and realloc to a trace file. + * mtrace.awk: Add source file which analyzes the trace file. + * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}. + (VERSION): Roll to 3.94.3. + + * breakpoint.c (breakpoint_1): Add a space to "i watch" output. + (check_duplicates): Don't bother with watchpoints. + (set_raw_breakpoint): Comment about danger of this routine. + (watch_command): Parse and eval all args before calling + set_raw_breakpoint. + + * solib.c (find_solib): Avoid error in referencing memory to + see if any more shared libraries have been added. This is + particularly useful if the target has terminated. Bug reported + by Peter Schauer. + + Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de> + in bringing up 3.94.2 on the Sun-3. + + * Makefile.dist: Include CFLAGS in rule for cplus-dem.o. + * breakpoint.c (enable_breakpoint): Check for valid watchpoint + expression (in scope) before reenabling watchpoint. + * signame.c (init_sigs): Add missing declaration of i, fix + sys_siglist declaration. + * source.c (list_command): Fixed range computation to use + lines_to_list (). + * stack.c (backtrace_command): Do not allow command if target has + no stack, print informative error message. + * target.c (target_command): Do not write into command line + because this fails if the target command is used in a user defined + command. [This change was enhanced by gnu to support any- + unique-prefix matching on target names.] + * valops.c (value_struct_elt): Avoid infinite loop on an + erroneous attempt to print the member of function (try p main.p). + +Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com) + + * expread.y (name_no_typename): Avoid reduce/reduce errors + caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT. + Since the GDB parser really doesn't use name_no_typename in a + name-only context, the parser can't tell the diff between + names and numbers here. Avoid allowing a name_no_typename + to be a NAME_OR_*INT to resolve the conflict. + +Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com) + + Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c): + + * valprint.c (val_print_fields): bitfield printing didn't handle + byte order.
