commit ae7207d033481191bdbf46f18afbb2fad0397730
Author: Joseph Myers <>
Date:   Fri Nov 24 22:25:03 2017 +0000

    Support testing _Float64x libm functions.
    This patch adds support for testing _Float64x libm functions.  A
    configuration with such functions sets float64x-alias-fcts = yes in a
    sysdeps Makeconfig file; until such settings are added, this test
    support is inactive.
    Tested for x86_64, including in conjunction with _Float64x support
    	* math/test-float64x.h: New file.
    	* math/Makefile (type-float64x-yes): New variable.
    	(test-types): Add $(type-float64x-$(float64x-alias-fcts)).
