alignment: store_one_arg vs emit_push_insn

[Richard Kenner]

+   if (to && MEM_ALIGN (to) > 0)
+     align = MEM_ALIGN (to);
+   if (align < MEM_ALIGN (from) && MEM_ALIGN (from) > 0)
+     align = MEM_ALIGN (from);
  
MEM_ALIGN is always > 0, so I think you mean:

    align = MIN (to ? MEM_ALIGN (to) : align, MEM_ALIGN (from));
