Implemented Jason Merrill's suggestions on Array Notation C++.
gcc/ChangeLog 2013-06-28 Balaji V. Iyer <balaji.v.iyer@intel.com> * builtins.def: Fixed the function type of CILKPLUS_BUILTIN. gcc/c/ChangeLog 2013-06-28 Balaji V. Iyer <balaji.v.iyer@intel.com> * c-parser.c (c_parser_array_notation): Removed rejection of array notations in an array of function pointers. gcc/c-family/ChangeLog 2013-06-28 Balaji V. Iyer <balaji.v.iyer@intel.com> * array-notation-common.c (length_mismatch_in_expr_p): Collapsed two if-statements and compared the trees directly using tree_int_cst_equal. (find_rank): Checked for array notations in function name to handle array notations in function pointers. (extract_array_notation_exprs): Likewise. (replace_array_notations): Likewise. (cilkplus_extract_an_triplets): Replaced safe_push with safe_grow_cleared. Also removed an unnecessary check to see if the node is of type ARRAY_NOTATION_REF. (fix_sec_implicit_args): Removed an unnecessary check for ADDR_EXPR. Also switched two if-statements to remove an unnecessary comparison. gcc/cp/ChangeLog 2013-06-28 Balaji V. Iyer <balaji.v.iyer@intel.com> * parser.c (cp_parser_array_notation): Removed rejection array notation of type function pointers. Added handling of array expressions when Cilk Plus is enabled. Took out type-checking. (cp_parser_postfix_open_square_expression): Moved normal array expr. parsing into cp_parser_array_notation when cilkplus is enabled. (cp_parser_compound_statement): Removed expansion of array notations. (cp_parser_ctor_initializer_opt_and_function_body): Likewise. (cp_parser_function_definition_after_declarator): Likewise. (cp_parser_selection_statement): Removed error reporting. (cp_parser_iteration_statement): Likewise. (cp_parser_direct_declarator): Removed error checking/reporting if array notations are used in the declarator. * pt.c (instantiate_decl): Likewise. (type_unification_real): Removed a check for ARRAY_NOTATION_REF. (cxx_eval_constant_expression): Removed ARRAY_NOTATION_REF case. (potential_constant_expression_1): Returned false for ARRAY_NOTATION_REF case. * cp-gimplify.c (cp_genericize): Added expansion of array notation expressions here. * cp-array-notation.c (make_triplet_val_inv): Removed loc and cry parameters. Replaced build_decls with get_temp_regvar with type as ptrdiff. (create_array_refs): Made the type-casting to ptrdiff_type. (replace_invariant_var): Added a check for void return type before creating new var. Replaced build_decl and build_min_nt_loc with get_temp_regvar. (expand_an_in_modify_expr): Ditto. Replaced body of redundant else with gcc_unreachable. Removed few unwanted checks. Made induction variable type as ptrdiff_type. Removed loc and complain arguments passed into make_triplet_val_inv. Replaced all modify expression's code from NOP EXPR to INIT EXPR. Replaced all forceful appending into stmt. list with the non-forceful one. Replaced some integer conversion and equality-checking to using tree_int_cst_equal. (expand_sec_reduce_builtin): All changes mentioned in above function expand_an_in_modify_expr. Made the new variable type of SEC_REDUCE_ANY/ALL_{NON}ZERO intrinsic functions as bool. (expand_array_notation_exprs): Removed SWITCH_EXPR case. Moved all the error reporting from parser to this function. Removed unwanted statements and checks from SWITCH_STMT, WHILE_STMT, and DO_STMT cases. (cilkplus_an_triplet_types_ok_p): Removed rejection of array notation in function pointers. (cp_expand_cond_array_notations): Added a new if statements to check if condition has a zero rank. If so, then just return. (expand_return_expr): Added a check for return expressions with a rank. Replaced get_tmp_regvar with a create_temporary_var. (build_array_notation_ref): Simplified and removed unwanted if-stmts. Moved common code outside if-statements. Moved type-checking from parser to here. * semantics.c (finish_return_stmt): Removed a check for return exprs. with a rank. * call.c (convert_like_real): Removed a check for array notation expression in a function. (build_over_call): Likewise. (magic_varargs_p): Added a check for builtin array notation function. Made this function non-static and removed its prototype. * cp-tree.h (magic_varargs_p): New prototype. * typeck.c (cp_build_function_call_vec): Removed automatic setting of nargs to the param->length when builtin reduction function is used. (convert_arguments): Replaced check for a constant_p function with margic_varargs_p function call. (cp_build_binary_op): Removed calling of the function find_correct_array_notation_type. (cp_build_addr_expr_1): Removed an unwanted if-statement. (convert_for_assignment): Removed automatic return of rhs when array notation builtin function is used. gcc/testsuite/ChangeLog 2013-06-28 Balaji V. Iyer <balaji.v.iyer@intel.com> * c-c++-common/cilk-plus/AN/decl-ptr-colon.c (main): Made this testcase c specific. * c-c++-common/cilk-plus/AN/decl-ptr-colon.c (main): Changed dg-error strings to match the fixed error messages. * c-c++-common/cilk-plus/AN/misc.c (main): Likewise. * c-c++-common/cilk-plus/AN/rank_mismatch.c (main): Added a new error message check.
