commit bf8ae8c09ab7ae4c402f26fd1a2cff4b64e50eea
Author: Joseph Myers <joseph@codesourcery.com>
Date:   Wed Dec 12 22:33:06 2018 +0000

    Remove x86 mathinline.h hypot inline.
    
    Continuing the removal of bits/mathinline.h inlines that would better
    be done by the compiler, this patch removes an x86 inline for hypot
    functions (only for fast-math, only for non-SSE 32-bit x86).  I've
    filed <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=88474> for adding
    such an inline as an optimization in GCC.
    
    Tested for x86_64 and x86.
    
    	* sysdeps/x86/fpu/bits/mathinline.h (hypot): Remove inline
    	definition.
