    • [Darwin] Update darwin_binds_local_p. · 6eee5151 
      The use of default_binds_local_p had got out of sync with the varasm
changes, this restores the call to be direct.  In practice, we add some
further tests to determine local binding - but this callback is used for
the initial assessments made by default_encode_section_info().

    • [C++ PATCH] clone_function_decl breakup · c1d78170 
      https://gcc.gnu.org/ml/gcc-patches/2019-10/msg01083.html
This patch, from the modules branch, breaks out function cloning from the
method vector updating. We have a new function, build_clones,
which does the building, returning a count of the number of clones
(2 or 3). clone_function_decl separately adds them to the method
vector, if they should be added. I suppose this could have used
FOR_EVERY_CLONE, but I went with the counting scheme.

	* class.c (build_clones): Break out of clone_function_decl.  Just
	build the clones.
	(clone_function_decl): Call build_clones, then maybe add them to
	the method vector.

      GCC Administrator committed
    • Rename attribute-related functions and productions in C parser. · 783bfe5e 
      The C2x attribute syntax, [[ ]], appears in different places in the
syntax from GNU __attribute__, and, where they can appear in the same
place in the syntax, they do not always appertain to the same entity.
(For example, in "int func(void) ATTRS;", GNU attributes appertain to
the declaration but C2x attributes appertain to the function type.)

Thus, the C parser needs to handle the two kinds of attributes
separately, with each place in the syntax accepting whatever kinds of
attributes are appropriate there and applying them to the relevant
entities.  This patch prepares for this by renaming parser functions
relating to attributes to make clear they are specifically about GNU
attributes and renaming syntax productions likewise to avoid confusing
with the C2x attributes syntax productions.

Where comments refer to attributes, this has only be changed where it
is clear that in the context they are referring specifically to the
gnu-attributes syntax.  There may be other places that also end up
changing to refer to gnu-attributes as part of the C2x attributes
implementation, if more detailed examination of those places shows
they are also specific to gnu-attributes.  (I do not expect code
dealing with semantics of attributes outside of the parser to need to
change; as for C++, it will be possible to use existing attributes
inside [[]] with the gnu:: form of the attribute name.)

Bootstrapped with no regressions on x86_64-pc-linux-gnu.
