GNU C Library master sources branch master updated. glibc-2.26.9000-741-g3683b42


This is an automated email from the git hooks/post-receive script. It was
generated because a ref change was pushed to the repository containing
the project "GNU C Library master sources".

The branch, master has been updated
       via  3683b423a4895ecd360fbbe118a027b7c2cf52ec (commit)
      from  58c4a1612db6a52d814d856f20bf93f1cac45232 (commit)

commit 3683b423a4895ecd360fbbe118a027b7c2cf52ec
Author: Joseph Myers <joseph@codesourcery.com>
Date:   Tue Nov 7 23:47:53 2017 +0000

    Handle more _FloatN, _FloatNx types in include/float.h.
    
    Continuing the preparation for additional _FloatN / _FloatNx type
    support, this patch adds support in include/float.h.  This header
    defines macros for _Float128 properties when using compilers before
    GCC 7 that lack those macros in <float.h>.  For testing _Float32 /
    _Float64 / _Float32x / _Float64x functions with older compilers, such
    macros need to be defined for those types as well; for the older
    compilers, those types will always be typedefs for another type, so
    the definitions can be in terms of the macros for that other type.
    
    Tested for x86_64.
