Vl-parse-task-item-declaration-noatts

Verilog-2005 only. Match task_item_declaration except for the attributes. Also can be used to match function_item_declaration.

Signature

(vl-parse-task-item-declaration-noatts 
     atts &key (tokstream 'tokstream) 
     (config 'config)) 
 
  → 
(mv errmsg? value new-tokstream)

Arguments

config — Guard (vl-loadconfig-p config).

Note: again, function_item_declaration is the subset of task_item_declaration where the only ports are inputs. We therefore just writer a parser for task_item_declaration, then separately check (when we construct the function declaration) that all ports are inputs.

task_item_declaration ::= block_item_declaration
                        | { attribute_instance } tf_input_declaration ';'
                        | { attribute_instance } tf_output_declaration ';'
                        | { attribute_instance } tf_inout_declaration ';'

function_item_declaration ::= block_item_declaration
                            | { attribute_instance } tf_input_declaration ';'
