The testcase should not depend on undefined behavior of __builtin_ctz. So this changes it to use the g form with the 2nd argument of 32. Now the execution part of the testcase work. It still has a scan-assembler failure which should be fixed seperately. OK? Tested on aarch64-linux-gnu. gcc/testsuite/ChangeLog: * gcc.target/aarch64/vect_ctz_1.c (TEST): Use g form of the builtin and pass 32 as the value expected at 0.
