commit 1626a1cfcd6ba1cc64721be1036c2873211d499b
Author: Martin Sebor <msebor@redhat.com>
Date:   Fri Nov 9 17:24:12 2018 -0700

    Add support for GCC 9 attribute copy.
    
    GCC 9 has gained an enhancement to help detect attribute mismatches
    between alias declarations and their targets.  It consists of a new
    warning, -Wattribute-alias, an enhancement to an existing warning,
    -Wmissing-attributes, and a new attribute called copy.
    
    The purpose of the warnings is to help identify either possible bugs
    (an alias declared with more restrictive attributes than its target
    promises) or optimization or diagnostic opportunities (an alias target
    missing some attributes that it could be declared with that might
    benefit analysis and code generation).  The purpose of the new
    attribute is to easily apply (almost) the same set of attributes
    to one declaration as those already present on another.
    
    As expected (and intended) the enhancement triggers warnings for
    many alias declarations in Glibc code.  This change, tested on
    x86_64-linux, avoids all instances of the new warnings by making
    use of the attribute where appropriate.  To fully benefit from
    the enhancement Glibc will need to be compiled with
     -Wattribute-alias=2 and remaining warnings reviewed and dealt with
    (there are a couple of thousand but most should be straightforward
    to deal with).
    
    ChangeLog:
    
    	* include/libc-symbols.h (__attribute_copy__): Define macro unless
    	it's already defined.
    	(_strong_alias): Use __attribute_copy__.
    	(_weak_alias,  __hidden_ver1,  __hidden_nolink2): Same.
    	* misc/sys/cdefs.h (__attribute_copy__): New macro.
