I committed the following changes to the testsuite:

1999-07-27  Michael Meissner  <meissner@cygnus.com>

	* 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,
	converting double to long double.

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