Hi,
I'm new to bison and need help to acheive my following syntax,
syntax1: decl_spec semicolon
syntax2: decl_spec decl_attrib(optional) init_spec decl_attrib(optional)
semicolon
To achieve this i wrote bison grammar as,
declaration: decl_spec semicolon
|decl_spec decl_attrib in
While Bison has only one token lookahead, it has infinite memory. If
something is optional it is best to write two reduction rules. Though
the combinations do grow exponentially. In your case:
syntax1 : decl_spec ';'
| decl_spec init_spec ';'
| decl_spec init_spec decl_attrib ';'
| decl_s
