Replace some more nvvm.annotations with function attributes, auto-upgrading the annotations as needed. These new attributes will be more idiomatic and compile-time efficient than the annotations. - !"maxclusterrank" / !"cluster_max_blocks" -> "nvvm.maxclusterrank" - !"minctasm" -> "nvvm.minctasm" - !"maxnreg" -> "nvvm.maxnreg"
