Confirmed.  The bug is in tree-tailcall.c:independent_of_stmt_p.  The loop that
looks up PHI arguments, ought to handle gimple_min_invariants it finds in PHI
operands.  It should not assume that they are all SSA_NAMEs.

Not quite sure what the right to do is here.  We are analyzing

ret_1 in statement T.2_6 = ret_1 + ret2_2;

and abort as soon as we get to the first operand of

# ret_1 = PHI <0(2), ret_11(1)>;


Jeff, IIRC you implemented this.
