Bug ID: 46123
Summary: unsupported ARM NEON intrinsic in aarch32 for
supported instructions
Product: clang
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: C++

It seems that arm_neon.h that is shipped in android ndk r21 does not support
certain neon intrinsics in Aarch32 mode even though corresponding instruction
exist in ISA. The same ones are supported in Aarch64. I ran into the issue for
the following intrinsics (not sure if other intrinsics may have similar issue):
vcopyq_laneq_*
vsqrtq_
vdivq_
