+       * execute/ieee/fp-cmp-2.c: New file, clone from fp-cmp-1.c,
+       converting double to float.

+       * execute/ieee/fp-cmp-3.c: New file, clone from fp-cmp-1.c,

+       * noncompile/920507-1.c (x): Rename asm register from fr1 to
+       unknown_register, since fr1 is a legitimate register on some
+       machines.
