This has missed 6.0, but should be acceptable to roll into 6.0.1.

Actually if we make it like this:

#include 
#include 

int main(int ac, char **av)
{
for (int i = 0; i < 32; ++i)
if ((int)(getauxval(AT_HWCAP2) & (1 << i)))
printf("%d\n", i);
}


clang mytest.c -target aarch64-linux-gnu -fsanitize=memtag -march=armv8+memtag
qemu-aarch64 --cpu max -L /usr/aarch64-linux-gnu ./a.out

I see only: HWCAP_FP HWCAP_CRC32 HWCAP_ATOMICS
So no HWCAP2_BTI as well.
