(It works on power 32bit because longs are 32bit and therefore no need to cast). Can someone please suggest a target-supports define (or another method) I can use to disable this test for power 64bit (but not 32bit) ? I tried using vect_multiple_sizes, but that will also disable the test on x86 without avx. Thanks, Alan.
