;; We need a special mutual exclusion (to be used in addition to

;; cortex_a8_neon_issue_dp) for the case when an instruction such as

;; vmla.f is forwarded from E5 of the floating-point multiply pipeline to

;; E2 of the floating-point add pipeline.  On the cycle previous to that

;; forward we must prevent issue of any instruction to the floating-point

;; add pipeline, but still allow issue of a data-processing instruction

;; to any of the other pipelines.

(define_cpu_unit "cortex_a8_neon_issue_fadd" "cortex_a8_neon")

;; Patterns of reservation.

;; We model the NEON issue units as running in parallel with the core ones.

;; We assume that multi-cycle NEON instructions get decomposed into

;; micro-ops as they are issued into the NEON pipeline, and not as they

;; are issued into the ARM pipeline.  Dual issue may not occur except

;; upon the first and last cycles of a multi-cycle instruction, but it

;; is unclear whether two multi-cycle instructions can issue together (in

;; this model they cannot).  It is also unclear whether a pair of

;; a multi-cycle and single-cycle instructions, that could potentially

;; issue together, only do so if (say) the single-cycle one precedes

;; the other.
