-;; There are 3 pipelines in the VFP11 unit.
-;;
-;; - A 8-stage FMAC pipeline (7 execute + writeback) with forward from
-;; fourth stage for simple operations.
-;;
-;; - A 5-stage DS pipeline (4 execute + writeback) for divide/sqrt insns.
-;; These insns also uses first execute stage of FMAC pipeline.
-;;
-;; - A 4-stage LS pipeline (execute + 2 memory + writeback) with forward from
-;; second memory stage for loads.
-
-;; We do not model Write-After-Read hazards.
-;; We do not do write scheduling with the arm core, so it is only necessary
-;; to model the first stage of each pipeline
-;; ??? Need to model LS pipeline properly for load/store multiple?
-;; We do not model fmstat properly. This could be done by modeling pipelines
-;; properly and defining an absence set between a dummy fmstat unit and all
-;; other vfp units.
