r121253 - in /trunk/gcc: ChangeLog fold-const.c...


Author: sayle
Date: Sun Jan 28 05:04:48 2007
New Revision: 121253

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=121253
Log:

	* tree.c (tree_fold_gcd): Delete.
	* tree.h (tree_fold_gcd): Remove prototype.
	* tree-data-ref.c (tree_fold_divides_p): Don't use tree_fold_gcd to
	test whether one constant integer is a multiple of another.  Instead
	call int_const_binop with TRUNC_MOD_EXPR and test for a zero result.
	* fold-const.c (multiple_of_p):  We've determined both TOP and
	BOTTOM are integer constants so we can call int_const_binop directly
	instead of the more generic const_binop.
