[PATCH 3/3] Remove HP-UX references fom testsuite

[Pedro Alves]

I looked this one over too.  A few minor comments below, but
otherwise looks good to me.  Thanks for doing this!

Typo: "ex: Likewise.p" -> "exp: Likewise."

This case can be removed.  GDB doesn't ever output this.

This last one used to only run on hpux.  It seems like it'll now fail
on is_address_zero_readable targets -- the non-error alternative assumes
the variable's value is "0xa" ?

You could guard it with "if [is_address_zero_readable]", but, that
proc does "x 0" internally, so it sounds like it'd be pointless?

You should remove the HP-UX reference at the top too then.
But, GDB doesn't use the dg-* markers.  Note the comment at the top:

/* This file comes from GCC.  If you are tempted to change it,
   consider also changing the copy there.  */

I'd either leave it be, or, remove the whole dg-* comment block.

Comparing our copy to the gcc copy, that's the only bit that diverged so far:
