* builtins.def (BUILT_IN_LFLOOR, BUILT_IN_LFLOORF, BUILT_IN_LFLOORL)

	(BUILT_IN_LLFLOOR, BUILT_IN_LLFLOORF, BUILT_IN_LLFLOORL): New.
	* optabs.h (enum optab_index): Add new OTI_lfloor.
	(lfloor_optab): Define corresponding macro.
	* optabs.c (init_optabs): Initialize lfloor_optab.
	* genopinit.c (optabs): Implement lfloor_optab using lfloorsi2
	and lfloordi2 patterns.

	* builtins.c (expand_builtin_int_roundingfn): New prototype.
	(expand_builtin_int_roundingfn): New function.
	(fold_builtin_int_roundingfn): New prototype.
	(fold_builtin_int_roundingfn): New function, renamed from
	fold_builtin_lround.
	Handle BUILT_IN_LROUND{,F,L}, BUILT_IN_LLROUND{,F,L} and
	BUILT_IN_LFLOOR{,F,L}, BUILT_IN_LLFLOOR{,F,L}.
	(fold_builtin_1): Fold BUILT_IN_LFLOOR{,F,L} and
	BUILT_IN_LLFLOOR{,F,L} using fold_builtin_int_roundingfn.
	(mathfn_built_in): Handle BUILT_IN LFLOOR and BUILT_IN_LLFLOOR.
	(expand_builtin): Expand BUILT_IN_LFLOOR{,F,L} and
	BUILT_IN_LLFLOOR{,F,L} using expand_builtin_int_roundingfn.

	* convert.c (convert_to_integer): Convert (long int)floor{,f,l},
	into lfloor built-in function and (long long int)floor{,f,l} into
	llfloor built-in function.
	* fold-const.c (tree_expr_nonnegative_p): Add BUILT_IN_LFLOOR and
	BUILT_IN_LLFLOOR.

testsuite:

	* gcc.dg/builtins-53.c: New test.
