sparc.h (INIT_TARGET_OPTABS): If ARCH64, set the 32-bit ABI libfuncs to NULL.

2002-06-24  David S. Miller  <davem@redhat.com>

	* config/sparc/sparc.h (INIT_TARGET_OPTABS): If ARCH64, set the
	32-bit ABI libfuncs to NULL.

	* expmed.c (expand_divmod): Do not set optab1/optab2 to the shift
	optabs if op1 is const0_rtx.
