Subject: [PATCH 00/17] genksyms: fix conflicts and syntax errors in parser


This series fixes several long-standing issues in genksyms.

 - The parser contains grammatical ambiguities, including both
   reduce/reduce and shift/reduce conflicts.

 - There are several hidden syntax errors
   When a syntax error occurs, the type becomes UNKNOWN, and
   precise CRC calculation becomes impossible.



Masahiro Yamada (17):
  genksyms: rename m_abstract_declarator to abstract_declarator
  genksyms: rename cvar_qualifier to type_qualifier
  genksyms: reduce type_qualifier directly to decl_specifier
  genksyms: fix 6 shift/reduce conflicts and 5 reduce/reduce conflicts
  genksyms: fix last 3 shift/reduce conflicts
  genksyms: remove Makefile hack
  genksyms: restrict direct-abstract-declarator to take one
    parameter-type-list
  genksyms: restrict direct-declarator to take one parameter-type-list
  genksyms: record attributes consistently for init-declarator
  genksyms: decouple ATTRIBUTE_PHRASE from type-qualifier
  genksyms: fix syntax error for attribute before abstract_declarator
  genksyms: fix syntax error for attribute before nested_declarator
  genksyms: fix syntax error for attribute after abstact_declarator
  genksyms: fix syntax error for attribute after 'struct'
  genksyms: fix syntax error for attribute after 'union'
  genksyms: fix syntax error for builtin (u)int*x*_t types
  genksyms: fix syntax error for attribute before init-declarator
