+Extend .gdbinit mechanism to specify name on command line, allow for

+@c Configure the @value{GDBN} expression parser to parse the listed languages.
+@c @samp{all} configures @value{GDBN} for all supported languages. To get a

+@c option, @value{GDBN} is configured to parse all supported languages.
+
+Add an "info bfd" command that displays supported object formats,
+similarly to objdump -i.
START_INFERIOR_TRAPS_EXPECTED need never be defined to 2, since that
is its default value. Clean this up.
Perhaps "i source" should take an argument like that of "list".

unpack_double() does not handle IEEE float on the target unless the host

an error.

GDB does four ioctl's for every command, probably switching terminal modes
to/from inferior or for readline or something.
Generalize and Standardize the RPC interface to a target program,
improve it beyond the "ptrace" interface, and see if it can become a
-standard for remote debugging.

Remove all references to:
text_offset
both source and assembly code ("set symbol-filename on" is a partial
solution).
-xcoffexec.c should be eliminated, contents going into either exec.c
-or rs6000-nat.c.
-
investigate "x/s 0" (right now stops early) (I think maybe GDB is
using a 0 address for bad purposes internally).
-Play with RS/6000 shared libraries (using shared library tests
-listed in testsuite/TODO as a guide). (Schauer has done shared
-library stuff on most other platforms but has not touched the
-RS/6000).
-
-Make "info path" and path_comma work again (but independent of the

environment either of gdb or that we'll pass to the inferior).
Make GDB understand the GCC feature for putting octal constants in
Clean up formatting of "info registers" on MIPS and 88k. See if it
is possible to do this generically across all target architectures.

Check that unmatched RBRAC doesn't abort().
/foo/bar.c works whether compiled by cc /foo/bar.c, or cd /foo; cc

Fix byte order and int size sins in tm-a29k.h
Make a watchpoint which contains a function call an error (it is
broken now, making it work is probably not worth the effort).
-Make SIGINT handling independent of the debugging target. Do this
-by adding a new target_send_signal which sends a signal to a running
-process. (This is to replace the calls to signal() in remote.c).
+Re-do calls to signal() in remote.c, and inflow.c (set_sigint_trap and
+so on) to be independent of the debugging target, using target_stop to
+stop the inferior. Probably the part which is now handled by
+interrupt_query in remote.c can be done without any new features in
+the debugging target.
New test case based on weird.exp but in which type numbers are not
renumbered (thus multiply defining a type). This currently causes an
If try to modify value in file with "set write off" should give
appropriate error not "cannot access memory at address 0x65e0".
-What the hell is no_std_regs in tm-z8k.h???
-This fixes the case where a target defines no standard reg names,
-and the parsing of $pc gets confused when it should be an invalid expr.
-
-Make DEBUG_EXPRESSIONS a maintenance command, dependent on
-MAINTENANCE_COMMANDS.
+Why do we allow a target to omit standard register names (NO_STD_REGS
+in tm-z8k.h)? I thought the standard register names were supposed to
+be just that, standard.
Allow core file without exec file on RS/6000.
PAGE_SIZE redefined warnings on AIX. Probably should be using
BFD_PAGE_SIZE throughout BFD.
+Rewrite proceed, wait_for_inferior, and normal_stop to clean them up.
+Suggestions:
+
+ 1) Make each test in wait_for_inferior a seperate subroutine
+ call.
+ 2) Combine wait_for_inferior and normal_stop to clean up
+ communication via global variables.
+ 3) See if you can find some way to clean up the global
+ variables that are used; possibly group them by data flow
+ and information content?
+
+Work out some kind of way to allow running the inferior to be done as
+a sub-execution of, eg. breakpoint command lists. Currently running
+the inferior interupts any command list execution. This would require
+some rewriting of wait_for_inferior & friends, and hence should
+probably be done in concert with the above.
+
+Add function arguments to gdb user defined functions.
+
+Add convenience variables that refer to exec file, symbol file,
+selected frame source file, selected frame function, selected frame
+line number, etc.
+
+Add a "suspend" subcommand of the "continue" command to suspend gdb
+while continuing execution of the subprocess. Useful when you are
+debugging servers and you want to dodge out and initiate a connection
+to a server running under gdb.
+
+Add stab information to allow reasonable debugging of inline functions
+(possibly they should show up on a stack backtrace? With a note
+indicating that they weren't "real"?).
+
+Modify the naked "until" command to step until past the current source
+line, rather than past the current pc value. This is tricky simply
+because the low level routines have no way of specifying a multi-line
+step range, and there is no way of saying "don't print stuff when we
+stop" from above (otherwise could just call step many times).
+
+Modify the handling of symbols grouped through BINCL/EINCL stabs to
+allocate a partial symtab for each BINCL/EINCL grouping. This will
+seriously decrease the size of inter-psymtab dependencies and hence
+lessen the amount that needs to be read in when a new source file is
+accessed.
+
+Do an "x/i $pc" after each stepi or nexti.
+
+Modify all of the disassemblers to use printf_filtered to get correct
+more filtering.
+
+Modify gdb to work correctly with Pascal.
+
+Add a command for searching memory, a la adb. It specifies size,
+mask, value, start address. ADB searches until it finds it or hits
+an error (or is interrupted).
+Remove the range and type checking code and documentation, if not
+going to implement.
