This also fails on 32-bit Solaris/SPARC with Sun as, which has:

        sethi   %hi(_ZN1S5xyzzyEv), %g1
        jmp     %g1 + %lo(_ZN1S5xyzzyEv)
        sethi   %hi(_ZN1S5xyzzyEv), %g1
        jmp     %g1 + %lo(_ZN1S5xyzzyEv)

On the other hand, both 64-bit with Sun as and 32-bit with gas have

        call    _ZN1S5xyzzyEv, 0
        call    _ZN1S5xyzzyEv, 0

This is OK, these are the 2 forms of a direct tail call on the SPARC: sethi/jmp
or call, depending on the capability of the assembler (HAVE_AS_RELAX_OPTION).

Then it's probably best to only look for

    (jmp|call)[^\n]*xyzzy

on SPARC, and ignore the sethi, so the count still matches?  Or, perhaps safer:

    (sethi[^\n]*xyzzy[^\n]*\n)?[^\n]*(jmp|call)[^\n]*xyzzy

That seems sufficient, IIUC the point is to have a symbol in the jmp/call.  As
I usually don't test with Sun as, please go ahead with whatever works for you.
