Plus
	array notation built-in reduction functions.
	* doc/passes.texi (Passes): Added documentation about changes done
	for Cilk Plus.
	* doc/invoke.texi (C Dialect Options): Added documentation about
	the -fcilkplus flag.
	* Makefile.in (C_COMMON_OBJS): Added 
c-family/array-notation-common.o.
	(BUILTINS_DEF): Depend on cilkplus.def.
	* builtins.def: Include cilkplus.def.  Define 
DEF_CILKPLUS_BUILTIN.
	* builtin-types.def: Define BT_FN_INT_PTR_PTR_PTR.
	* cilkplus.def: New file.

gcc/c-family/ChangeLog
2013-05-28  Balaji V. Iyer  <balaji.v.iyer@intel.com>

	* c-common.c (c_define_builtins): When cilkplus is enabled, the
	function array_notation_init_builtins is called.
	(c_common_init_ts): Added ARRAY_NOTATION_REF as typed.
	* c-common.def (ARRAY_NOTATION_REF): New tree.
	* c-common.h (build_array_notation_expr): New function declaration.
	(build_array_notation_ref): Likewise.
	(extract_sec_implicit_index_arg): New extern declaration.
	(is_sec_implicit_index_fn): Likewise.
	(ARRAY_NOTATION_CHECK): New define.
	(ARRAY_NOTATION_ARRAY): Likewise.
	(ARRAY_NOTATION_START): Likewise.
	(ARRAY_NOTATION_LENGTH): Likewise.
	(ARRAY_NOTATION_STRIDE): Likewise.
	* c-pretty-print.c (pp_c_postifix_expression): Added a new case for
	ARRAY_NOTATION_REF.
	(pp_c_expression): Likewise.
	* c.opt (flag_enable_cilkplus): New flag.
	* array-notation-common.c: New file.

gcc/c/ChangeLog
2013-05-28  Balaji V. Iyer  <balaji.v.iyer@intel.com>

	* c-typeck.c (build_array_ref): Added a check to see if array's
	index is greater than one.  If true, then emit an error.
	(build_function_call_vec): Exclude error reporting and checking
	for builtin array-notation functions.
	(convert_arguments): Likewise.
	(c_finish_return): Added a check for array notations as a return
	expression.  If true, then emit an error.
	(c_finish_loop): Added a check for array notations in a loop
	condition.  If true then emit an error.
	(lvalue_p): Added a ARRAY_NOTATION_REF case.
	(build_binary_op): Added a check for array notation expr inside
	op1 and op0.  If present, we call another function to find correct
	type.
	* Make-lang.in (C_AND_OBJC_OBJS): Added c-array-notation.o.
	* c-parser.c (c_parser_compound_statement): Check if array
	notation code is used in tree, if so, then transform them into
	appropriate C code.
	(c_parser_expr_no_commas): Check if array notation is used in LHS
	or RHS, if so, then build array notation expression instead of
	regular modify.
	(c_parser_postfix_expression_after_primary): Added a check for
	colon(s) after square braces, if so then handle it like an array
	notation.  Also, break up array notations in unary op if found.
	(c_parser_direct_declarator_inner): Added a check for array
	notation.
	(c_parser_compound_statement): Added a check for array notation in
	a stmt.  If one is present, then expand array notation expr.
	(c_parser_if_statement): Likewise.
	(c_parser_switch_statement): Added a check for array notations in
	a switch statement's condition.  If true, then output an error.
	(c_parser_while_statement): Similarly, but for a while.
	(c_parser_do_statement): Similarly, but for a do-while.
	(c_parser_for_statement): Similarly, but for a for-loop.
	(c_parser_unary_expression): Check if array notation is used in a
	pre-increment or pre-decrement expression.  If true, then expand
	them.
	(c_parser_array_notation): New function.
	* c-array-notation.c: New file.
	* c-tree.h (is_cilkplus_reduce_builtin): Protoize.
