Yes, it is OK.

You might consider putting the testcase in gcc.target/ia64 since it is
very IA-64 specific.  You won't get multiple runs with different
optimizations here, but I suspect you really only need one run with -O2
or whatever to show the problem.

In the docs, unspec and unspec_volatile should be inside @code{}, and
you shouldn't be using [] to try to abbreviate here.  I'd suggest
something like this:

This target hook returns nonzero if @var{x}, an @code{unspec} or
@code{unspec_volatile} operation, might cause a trap.  Targets can use
this hook to enhance precision of analysis for @code{unspec} and
@code{unspec_volatile} operations.  You may call @code{may_trap_p_1} to
analyze inner elements of @var{x} in which case @var{flags} should be
passed along.
