;; FP vector operations.
;; AArch64 AdvSIMD supports single-precision (32-bit) and 
;; double-precision (64-bit) floating-point data types and arithmetic as
;; defined by the IEEE 754-2008 standard.  This makes them vectorizable 
;; without the need for -ffast-math or -funsafe-math-optimizations.
;;
;; Floating-point operations can raise an exception.  Vectorizing such
;; operations are safe because of reasons explained below.
;;
;; ARMv8 permits an extension to enable trapped floating-point
;; exception handling, however this is an optional feature.  In the
;; event of a floating-point exception being raised by vectorised
;; code then:
;; 1.  If trapped floating-point exceptions are available, then a trap
;;     will be taken when any lane raises an enabled exception.  A trap
;;     handler may determine which lane raised the exception.
;; 2.  Alternatively a sticky exception flag is set in the
;;     floating-point status register (FPSR).  Software may explicitly
;;     test the exception flags, in which case the tests will either
;;     prevent vectorisation, allowing precise identification of the
;;     failing operation, or if tested outside of vectorisable regions
;;     then the specific operation and lane are not of interest.

;; FP arithmetic operations.
