David Edelsohn <dje at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |WAITING Last reconfirmed| |2018-04-05 Ever confirmed|0 |1 --- Comment #1 from David Edelsohn <dje at gcc dot gnu.org> --- What two additional instructions? x86 is a CISC architecture and Power is a RISC architecture. x86 has an instruction that directly performs an indirect call through a pointer. Power must explicitly load the pointer and move it to the appropriate register to perform an indirect branch. One can comment / questions that the *SEQUENCE* appears to require more time on Power than the equivalent sequence on x86. But directly comparing instructions and counting instructions in two different ISAs without context is not meaningful.
