[antlr-interest] C Grammar - Symbol Suffix Related..

[Sarnath K - ERS, HCLTech]

Hi There! Compiler Gurus!

I have a doubt on the following productions of the C grammar.

If you look at "direct_declarator", it tries to specify a multi-dimensional array (or) a function.
The "*" on the declarator_suffix ensures that multi-dimensional arrays can  be handled.
However "*" does not serve any purpose for functions. We don't declare functions like "f(...)(...)(...)"
Moreover "C" does NOT allow functions to return arrays (int  unsupported()[]);

Any ideas why the grammar is so? I am planning to modify it to suit "C" style correctly - so I can setup the symbol table pretty easily.
Any help? Many Thanks,

"
direct_declarator
        :   (     IDENTIFIER  |  ('(' declarator ')')     )
            (declarator_suffix)*
        ;

declarator_suffix
    :   '[' constant_expression ']'
    |   '[' ']'
    |   '(' parameter_type_list ')'
    |   '(' identifier_list ')'
    |   '(' ')'
    ;
"

Best Regards,
Sarnath
