Yes, was helpfull for me;)

I found the problem, the assignments to set the bits are wrong.

Instead of 
__cpu_features.feature[index_AVX_Usable] = 1;

use
__cpu_features.feature[index_AVX_Usable]
	    |= bit_AVX_Usable;

The same for the FMA4 test.

Carlos, I suggest to add the test to glibc as well,
Andreas
