--- Comment #3 from Christophe Lyon <clyon at gcc dot gnu.org> --- As of r251385, these intrinsics are still not implemented (except for vtst_p64). But looking at http://infocenter.arm.com/help/topic/com.arm.doc.ihi0073a/IHI0073A_arm_neon_intrinsics_ref.pdf I noticed that many more intrinsics are not implemented (for instance vceqz for non-p64 versions). Is there a script-friendly version of this pdf document that could be parsed to build the list of non-implemented intrinsics?
