  | gdb has no need for PT_STEP support for the Alpha.

What about other debuggers?   gdb is not the world.   The best two
debuggers I've used on unix (by large margins in each case) were
adb for low level stuff (I believe there are lots of people here who
would love to have adb back), and ups for source level debugging.

[ups is less well known - it is/was from UKC (Kent, UK) - originally for
sunview (or sunwindows or one of those) but ported to X as well - and,
naturally, for a.out SunOS and I think, 68K in particular, though there
may have been sparc support as well - it turned into a front end for gdb
at which time it lost much of its speed and flexibility, but I guess it made
maintenance a lot simpler - I gave up on it when that happened, so I'm
not sure if it survives or not - if it does, it should be added to pkgsrc.]

If PT_STEP is possible on the Alpha, and causes no particular harm, is
there really a good reason to omit it, regardless of whether gdb needs it
or not?
