* dwarf2out.c (gen_member_die): Handle inline static data member
definitions.
c-family/
* c-cppbuiltin.c (c_cpp_builtins): Add __cpp_inline_variables.
cp/
* cp-tree.h (struct lang_type): Shrink language field to 1 bit
from 4. Add var_declared_inline_p field. Mention 2 spare bits.
(DECL_VAR_DECLARED_INLINE_P): Define.
(SET_DECL_VAR_DECLARED_INLINE_P): Define.
(DECL_INLINE_VAR_P): Define.
(diagnose_inline_vars_for_namespace): Declare.
* decl.c (diagnose_inline_vars_for_namespace): New function.
(duplicate_decls): For static data members copy
DECL_DECLARED_CONSTEXPR_P.
(redeclaration_error_message): Handle C++17 redundant redeclaration
of constexpr static data member outside of class.
(maybe_commonize_var): Handle inline variables.
(check_initializer): Ignore inline variables for diagnostics.
Adjust diagnostic wording for C++17.
(make_rtl_for_nonlocal_decl): Allow in-class definition of
inline static data members.
(bad_specifiers): Don't diagnose inline on variables here.
(grokvardecl): Add inlinep argument, non-static const inline variables
are TREE_PUBLIC.
(check_static_variable_definition): Return early also for inline
variables.
(grokdeclarator): Handle inline variables and inline static data
members.
* typeck2.c (store_init_value): Don't diagnose non-constant
initializers for non-constexpr inline static data members.
* decl2.c (vague_linkage_p): Return true for inline variables.
(c_parse_final_cleanups): In-class declaration of inline static
data members is a definition. Call diagnose_inline_vars_for_namespace
through walk_namespaces.
* pt.c (instantiate_decl): Set pattern_defined for in-class definitions
of inline static data members.
