* obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
sections starting from zero, rather than making them consecutive.
This makes subsequent reloc calculations easier, esp if the
object format doesn't understand addends. (obj_coff_lcomm): (maybe
temporarily) allocate lcomm in .data rather than in .bss. It
seems that some tools can't cope with a non-zero sized bss
before linkage.
process will be the default target.
* target.c (find_default_run_target, find_default_attach,
find_default_create_inferior, return_zero): new functions.
(cleanup_target): Make return_zero the default for to_can_run.
* exec.c (exec_ops), core.c (core_ops): Replace child_attach and
child_create_inferior references with find_default_XXX instead.
* target.h (struct target_ops): new field, to_can_run.
(find_default_attach, find_default_create_inferior): new prototypes.
(target_can_run): new macro.
* Also added a zero (default) to_can_run element to all static
struct target_ops initializations throughout GDB, except:
* inftarg.c (child_ops): Use new child_can_run() to enable child runs.
* infrun.c (child_create_inferior): Clean up error handling when
no exec file is specified.
(child_attach): Don't require exec file.
through the target vector.
* inferior.h (kill_inferior_fast): remove declaration.
* main.c (disconnect): call quit_cover using catch_errors rather
than calling kill_inferior_fast directly. New way goes through
the target vector, handles attached processes, and writes
command history if appropriate.
(quit_cover): new function, wrapper for quit_command.
* convex-xdep.c, go32-xdep.c, hppabsd-xdep.c, hppahpux-xdep.c,
infptrace.c, procfs.c: Removed all instances of kill_inferior_fast,
inlining them into the local kill_inferior when needed.

* m68k-pinsn (print_insn_arg, fetch_arg): added support for
operands to memory management instructions, from WRS.

Replace with simple default to C before processing any init
files. There MUST be a language set, even in the absence of
init files or executables, or expression parsing fails.
symfile.c. Fixup places where command files are processed to
be consistent in setting a default language if none has been
previously set.
* symfile.c (set_initial_language): Add code moved from
main() that sets an initial default language when a new
symbol file is read.
* symfile.c (symbol_file_command): Call set_initial_language.
* symtab.c (find_main_psymtab): Add FIXME comment.
* blockframe.c (get_prev_frame_info): If INIT_FRAME_PC_FIRST is
set, run it before INIT_EXTRA_FRAME_INFO.
* stack.c (frame_info): If PRINT_EXTRA_FRAME_INFO defined, call it.
* mips-tdep.c (init_extra_frame_info): Only clobber the `frame'
(FP) value in the frame_info struct if it is zero (as from top of
execution stack).
(setup_arbitrary_frame): Implement FRAME_SPECIFICATION_DYADIC.
* mips-xdep.c (fetch_inferior_registers): ZERO_REGNUM always
comes back as zero. So does FP_REGNUM, as a trigger for
init_extra_frame_info.
* tm-mips.h (INIT_FRAME_PC_FIRST): Kludge, FIXME, defined to get
the program counter set before INIT_EXTRA_FRAME_INFO is run.
(INIT_FRAME_PC): Defined to null.
(PRINT_EXTRA_FRAME_INFO): print frame pointer location via symtab.
(FRAME_SPECIFICATION_DYADIC): Ask for two args in frame command.
Briefly explain MIPS stacks in GDB.
Rich and I believe the "real problem" was that both single_step
and target_resume were issuing PT_CONTINUE calls. This would
cause the second PT_CONTINUE to sometimes fail because the process
was already running.
* infptrace.c (child_resume): Remove AIX_BUGGY_PTRACE_CALL kludge.
* infptrace.c (child_resume): Don't deal with NO_SINGLE_STEP
here; it is dealt with at a gdb-target-independent level.
* rs6000-tdep.c (single_step): Don't call ptrace, we are a
high toned routine. Fix return type to void.
