These can be found in the [[openpower/isa/svfparith]] page if performing IEEE754 FP transforms. *(For fixed-point transforms, equivalent 3-in 2-out -integer operations would be required)*. These "butterfly" instructions +integer operations would be required, +currently under development)*. These "butterfly" instructions avoid the need for a temporary register because the two array positions being overwritten will be "in-flight" in any In-Order or Out-of-Order micro-architecture. -- 2.30.2
