The testcase gcc.target/aarch64/vect_ctz_1.c fails execution when running
with -march=armv9-a due to the testcase calls __builtin_ctz with a value of 0.
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.
