I've committed this change which seems to work fine on a graphical display but
not on a text-only terminal. Roughly, I've taken code from gud-display-line
and put it in gdb-assembler-custom. In this manner, I've created a variable
called gdb-overlay-arrow-string (set to "=>") but this doesn't have the
meaning given to overlay-arrow-string.
On a related note, I see that the overlay arrow is only represented as a
string on a text-only terminal. It seems to me that, now fringes can be
toggled, this should be extended to graphical displays where there is no
left-hand fringe.

I forgot to mention this:
You should use something like this to associate a string with
a custom overlay-arrow variable:
(put 'gdb-overlay-arrow-position 'overlay-arrow-string "=>")

Yes, that makes sense. I will look at it.

Btw, why doesn't gdb-ui.el live in progmodes, together with gud.el?

It did live together with gud.el before it was moved. Also, XEmacs has a
directory called debug but, as a previous thread observed, CVS doesn't handle
moves very well. I note the subversion has been released now, which might be
worth bearing in mind for the future. For the present, however, I agree that
gdb-ui.el should be moved to progmodes.

[This is extracted from my response to Nick Roberts re. supporting
GDB overlay arrows at C and assembler levels simultaneiously.
It hit the emacs-devel bit-bucket on Mar 02. ++kfs]
I have just installed changed to properly support multiple overlay
arrows.
[Some packages attempts to do this by making overlay-arrow-position
buffer local, but that doesn't really work well with the redisplay
code, as it may fail to notice changes to an overlay arrow in some
cases.]
To create an additional overlay arrow, create a new variable similar
to overlay-arrow-position, e.g. gdb-asm-overlay-arrow-position and
add it to the new variable overlay-arrow-variable-list; like this:
(push 'gdb-asm-overlay-arrow-position overlay-arrow-variable-list)
Then you can use gdb-asm-overlay-arrow-position just like the
overlay-arrow-position variable.
If you want to use a different fringe bitmap for the asm bitmap,
you can set it with
(require 'fringe)
(put 'gdb-asm-overlay-arrow-position 'overlay-arrow-bitmap
right-truncation-fringe-bitmap) ; the -> arrow
