The only major concern is in the upper SV Extension Levels: the Hazard
Management for increased number of Scalar Registers to 128 (in current
versions) but given that IBM POWER9/10 has VSX register numbering 64,
-and modern GPUs have 128, 256 amd even 512 registers this was deemed
+and modern GPUs have 128, 256 and even 512 registers this was deemed
acceptable. Strategies do exist in hardware for Hazard Management of
such large numbers of registers, even for Multi-Issue microarchitectures.
