Thanks, done. I haven't created a new Target-specific developers
options table but instead listed the targets the options apply to in
parentheses.
Attached is the latest iteration.
Thank you for the review,

* doc/invoke.texi (GCC Developer options): Add Target-specific
developer options subsection. Populate it with AArch64 and ARM
options.
(Options Summary): List the above.
Hmmm, there are still various problems here, and now I notice that
there's already an entry for -moverride= in the AArch64 Options section.
I need to go through the docs for all targets and make sure everything
is treated uniformly, so I think it would be more efficient for me to
take this over than to continue to iterate with you to get the patch
right. I'll try to get to it this weekend.
OK, I've checked in the attached patch.
I apologize for having given you a bum steer on this previously. :-(
When I dug around in the existing documentation lists, I found a dozen
or more existing target-specific developer options already listed in the
sections for the respective targets (FRV, in particular, has a whole
pile of them documented as "for debugging the compiler"). I thought it
made more sense in terms of the highly target-specific-ness of what many
of these options do to leave them all where they are now, as well as
less work than moving them all to another section. So I similarly added
the docs for the missing ARM and AArch64 developer options to the
existing sections for those respective targets as well.
