@ -9,6 +9,20 @@ General To Do List
This list is probably not up to date, and opinions vary about the
importance or even desirability of some of the items.
Document trace machinery.
Document overlay machinery.
Extend .gdbinit mechanism to specify name on command line, allow for
lists of files to load, include function of --tclcommand.
@c This does not work (yet if ever). FIXME.
@c @item --parse=@var{lang} @dots{}
@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 list of all supported languages, omit the argument. Without this
@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.
@ -382,9 +396,6 @@ 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.
Make DEBUG_EXPRESSIONS a maintenance command, dependent on
MAINTENANCE_COMMANDS.
Allow core file without exec file on RS/6000.
Make sure "shell" with no arguments works right on DOS.
@ -466,6 +477,9 @@ 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.
