Avinash Jayakar <avinashd at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |avinashd at gcc dot gnu.org --- Comment #1 from Avinash Jayakar <avinashd at gcc dot gnu.org> --- The following is my understanding, please correct me if I am wrong: In power8, we can use splat and shift for all constant upto word size and for double and quad word those constants whose bit[5:7] are 0 (or constant & 0xFFFFFFFFFFFFF1F == constant) or if it is -1 can also be achieved. In power9, as you mentioned xxspltib can be used for all constants, by doing constant%(2^size(type)).
