I'm not familiar with tree-ssa-structalias, but it appears to me that the "fix"
is quite simple? Or am I missing something? Here's the snippet from it, updated
with my attempt:

      if (restrict_var)
        {
          /* Now look at possible dereferences of ptr.  */
          imm_use_iterator ui;
          gimple *use_stmt;
          bool used = false;
          FOR_EACH_IMM_USE_STMT (use_stmt, ui, ptr)
            {
              if (!gimple_assign_single_p (use_stmt))
                {
                  /* ???  Calls.  */
                  if (gimple_code (use_stmt) != GIMPLE_ASM)
                    continue;

                  gasm *asm_stmt = as_a <gasm *> (use_stmt);
                  unsigned n = gimple_asm_ninputs (asm_stmt);
                  for (unsigned i = 0; i < n; i++)
                    {
                      tree op = TREE_VALUE (gimple_asm_input_op (asm_stmt, i));
                      used |= maybe_set_dependence_info (op, ptr, clique,
                                                         restrict_var,
                                                         last_ruid);
                    }
                  n = gimple_asm_noutputs (asm_stmt);
                  for (unsigned i = 0; i < n; i++)
                    {
                      tree op = TREE_VALUE (gimple_asm_output_op (asm_stmt,
i));
                      used |= maybe_set_dependence_info (op, ptr, clique,
                                                         restrict_var,
                                                         last_ruid);
                    }
                  continue;
                }


Does this not work? Sorry if I am missing something here.
