This change looks incomplete to me. @vnkozlov: Shouldn't we remove `AllocatePrefetchStyle == 3` completely? `PhaseMacroExpand::prefetch_allocation` still mentions "BIS instruction is used on SPARC as prefetch". Please note that PPC64 also still has an implementation for it (nodes with `predicate(AllocatePrefetchStyle == 3)`). I guess that we don't need it any more. Maybe we should check performance again. ------------- PR Comment: https://git.openjdk.org/jdk/pull/28240#issuecomment-3538765487
