Should be fixed with r11-6869-gd08677c11dc4b43cc8bab862d1c986563897ce3f and
r11-6871-g70ab52b8cafffedb05b55c68c847173ff80f2652 and

commit r11-6917-ge80f1f6b7a339bce1db03567e497658ae32d135e

    testsuite: Fix TBAA in sse*and*p[sd]*.c tests                               

    This patch drops the no-strict-aliasing hack in m128-check.h and instead    
    ensures the tests read objects with the right dynamic type.                 

    2021-01-26  Jakub Jelinek  <jakub@redhat.com>                               

            * gcc.target/powerpc/m128-check.h (CHECK_EXP): Remove               
            optimize ("no-strict-aliasing") attribute.                          
            * gcc.target/powerpc/sse-andnps-1.c (TEST): Copy e into float[4]    
            array to avoid violating TBAA.                                      
            * gcc.target/powerpc/sse2-andpd-1.c (TEST): Copy e.d into double[2] 
            array to avoid violating TBAA.                                      
            * gcc.target/powerpc/sse-andps-1.c (TEST): Copy e.f into float[4]   
            array to avoid violating TBAA.                                      
            * gcc.target/powerpc/sse2-andnpd-1.c (TEST): Copy e into double[2]  
            array to avoid violating TBAA.
