Update.

1998-12-25  Ulrich Drepper  <drepper@cygnus.com>

	* elf/dl-hash.h: Move to...
	* sysdeps/generic/dl-hash.h: ...here.  Correct parameter type (must
	be unsigned char).  Remove conditional from inner loop and rearrange
	binary operations (12-22% performance increase).
	* sysdeps/i386/i686/dl-hash.h: New file.  Yet 10% faster than
	optimized generic version.
