Parse-parameter-declaration

Parse a parameter declaration.

Signature

(parse-parameter-declaration parstate) 
  → 
(mv erp param span new-parstate)

Arguments

parstate — Guard (parstatep parstate).

Returns

param — Type (param-declonp param).

span — Type (spanp span).

new-parstate — Type (parstatep new-parstate), given (parstatep parstate).

A parameter declaration always starts with a list of one or more declaration specifiers, which we parse. Then we may have a declarator, an abstract declarator, or nothing. After that, we may have zero or more attribute specifiers (this is a GCC extension).

As explained in amb-declor/absdeclor, there is a complex syntactic overlap between declarators and abstract declarators. Thus, unless there is no (abstract or non-abstract) declarator, which we recognize by the presence of a comma or closed parenthesis or (if GCC extensions are enabled) an attribute keyword, we parse a possibly ambiguous declarator or abstract declarator, and generate a parameter declarator accordingly, and then a parameter declaration with the declaration specifiers.
