Here's a small test program. You're probably better equipped to test
clang svn.

--------
#include <math.h>
#include <stdio.h>
#include <stdlib.h>

int
main( int argc, char **argv ) {
	double d =3D strtod( argv[ 1 ], NULL );

	printf( "%e\n", ( double ) cos( d ));
	printf( "%e\n", ( double ) cosf( d ));
	printf( "%e\n", ( double ) cosl( d ));
	return( 0 );
}
--------

This is the current output of clang:

% clang -o cos cos.c -lm
% ./cos 1.23456789e20
6.031937e-01
1.234568e+20
2.814722e-01

The second number (cosf) is wrong. It should be a value between -1 and 1.=
