Subject: 	* builtins.c (fold_builtin_logarithm): Take decomposed
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=f27ba301fb6bbe51a6413456d412d41a9e113037;p=thirdparty%2Fgcc.git

	* builtins.c (fold_builtin_logarithm): Take decomposed
	arguments of CALL_EXPR.
	(fold_builtin_1): Update a call to fold_builtin_logarithm.
