+   There are two registers that can always be eliminated on the i386.
+   The frame pointer and the arg pointer can be replaced by either the
+   hard frame pointer or to the stack pointer, depending upon the
+   circumstances.  The hard frame pointer is not used before reload and
+   so it is not eligible for elimination.  */
