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
