I use ctags with vim and the OmniCppComplete plugin. Currently when generating my tags I do it individually for each library. For libc6 I use the following list of tokens
I had my own list and never thought about adding what you've already listed!
Here's that updated ignore list for libc6 that I've come up with (Ubuntu 14.04 and GCC 4.8.4) to use as input to the -I option of ctags:
__attribute__
__attribute_deprecated__
__attribute_format_arg__+
__attribute_format_strfmon__+
__attribute_malloc__
__attribute_noinline__
__attribute_pure__
__attribute_used__
__attribute_warn_unused_result__
__attribute_alloc_size__+
__attribute_const__
__attribute_artificial__
__wur
__THROW
__THROWNL
__BEGIN_DECLS
__END_DECLS
__BEGIN_NAMESPACE_STD
__END_NAMESPACE_STD
__USING_NAMESPACE_STD+
__BEGIN_NAMESPACE_C99
__END_NAMESPACE_C99
__USING_NAMESPACE_C99+
__warndecl+
__warnattr+
__errordecl+
__flexarr=[]
__fortify_function
__REDICRECT+
__REDIRECT_NTH+
__REDIRECT_NTHNL+
__ASMNAME+
__ASMNAME2+
__nonnull+
__always_inline
__extern_inline=extern
__extern_always_inline=extern
__extension__
__restrict
__restrict_arr
I also created the following ignore list for generating a tags file for libstdc++ (GCC 4.8.2 on Ubuntu 14.04) (again, this is input to the -I option):
_GLIBCXX_BEGIN_NAMESPACE_VERSION
_GLIBCXX_END_NAMESPACE_VERSION
_GLIBCXX_BEGIN_NAMESPACE_ALGO
_GLIBCXX_END_NAMESPACE_ALGO
_GLIBCXX_BEGIN_NAMESPACE_CONTAINER
_GLIBCXX_END_NAMESPACE_CONTAINER
_GLIBCXX_BEGIN_EXTERN_C
_GLIBCXX_END_EXTERN_C
_GLIBCXX_VISIBILITY+
_GLIBCXX_PURE
_GLIBCXX_CONST
_GLIBCXX_NORETURN
_GLIBCXX_CONSTEXPR=constexpr
_GLIBCXX_USE_CONSTEXPR=constexpr
_GLIBCXX_THROW_OR_ABORT+
_GLIBCXX_NOEXCEPT
_GLIBCXX_USE_NOEXCEPT
_GLIBCXX_THROW+
_GLIBCXX_NOTHROW
I changed __attribute__ to be: __attribute__+ to indicate it looks like a function and should be ignored.
Of course, I have created one for Boost as well, but I think I'll refrain from posting it until someone has a need.
