Description Simon Hosie 2014-02-18 21:10:30 PST 
clang --target=aarch64-linux-gnu -xc -c - << EOF
#include <arm_neon.h>
void fn(unsigned long *p, uint64x2_t v) {  vst1q_u64(p, v); }
EOF

gives me:
<stdin>:2:54: warning: incompatible pointer types assigning to 'unsigned long long *' from 'unsigned long *' [-Wincompatible-pointer-types]

Changing the pointer type to long long fixes things; unfortunately my /usr/aarch64-linux-gnu/include/stdint.h has uint64_t as simply `unsigned long`.

Seems to be fixed already (doesn't reproduce with trunk r208757). Tested both the ARM64 and AArch64 backend.
