[PATCH]: fix testsuite failure on sh* targets in builtin-ldexp-1.c

[Kaveh R. GHAZI]

Hi Kaz,

I noticed that in this posting:
http://gcc.gnu.org/ml/gcc-testresults/2007-02/msg00759.html

you're getting an error in gcc.dg/torture/builtin-ldexp-1.c which I
recently added.  Does this patch to the testcase fix it for you?  It's an
approach similar to what is used in gcc.dg/builtins-43.c (and 44, 45) for
tests using isnan() and/or isinf().  The sh target seems to imply
-ffinite-math-only which breaks any test using these functions because
the builtin folds all calls to zero in that case.

If it works, please let me know and I'll installed it.

		Thanks,
		--Kaveh

	* gcc.dg/torture/builtin-ldexp-1.c: Use -fno-finite-math-only on
	sh* targets.  Call the correct CKSGN macro.
