Commit 98c3a782 by Joseph Myers Committed by Joseph Myers
Options

c-tree.h (enum c_typespec_keyword): New. 

	* c-tree.h (enum c_typespec_keyword): New.
	(struct c_declspecs): Adjust description of "type".  Remove
	specbits, explicit_int_p and explicit_char_p.  Rename
	typedef_signed_p to explicit_signed_p.  Add default_int_p, long_p,
	short_p, signed_p, unsigned_p and complex_p.
	(finish_declspecs): New.
	* c-parse.in (datadef, datadecl, setspecs, decl, component_decl,
	typename): Call finish_declspecs.
	* c-decl.c (finish_declspecs): New.
	(declspecs_add_type): Check for combinations which cannot occur in
	valid specifier lists.  Update comments.
	(shadow_tag_warned): Remove checks done in finish_declspecs.
	Don't report useless type name if type defaulted to int.
	(grokdeclarator): Remove checks and actions done in
	finish_declspecs.  Don't allow for type being NULL.  Update for
	datastructures changes.  Initialize decl_attr.
	(build_null_declspecs, quals_from_declspecs): Update for
	datastructures changes.

testsuite:
	* gcc.dg/declspec-4.c, gcc.dg/declspec-5.c, gcc.dg/declspec-6.c:
	Update expected messages.
	* gcc.dg/declspec-13.c: New test.
