Hi,This patch documents issues with singleton vector types in the 4.9 AArch64 backend.
"On AArch64, the singleton vector types int64x1_t, uint64x1_t and float64x1_t exported by arm_neon.h are defined to be the same as their base types. This results in incorrect application of parameter passing rules to arguments of types int64x1_t and uint64x1_t, with respect to the AAPCS64 ABI specification. In addition, names of C++ functions with parameters of these types (including float64x1_t) are not mangled correctly. The current typedef declarations also unintentionally allow implicit casting between singleton vector types and their base types. These issues will be resolved in a near future release. See PR60825 for more information." OK for the wwwdocs repos? Thanks, Yufeng
