RET Return from subroutine This instruction branches unconditionally to an address in a register, with a hint that this is a subroutine return. 1 1 0 1 0 1 1 0 0 1 0 1 1 1 1 1 0 0 0 0 0 0 0 0 0 0 0 RET {<Xn>} constant integer n = UInt(Rn); <Xn> Is the 64-bit name of the general-purpose register holding the address to be branched to, encoded in the "Rn" field. Defaults to X30 if absent. bits(64) target = X[n, 64]; if IsFeatureImplemented(FEAT_GCS) && GCSPCREnabled(PSTATE.EL) then target = LoadCheckGCSRecord(target, GCSInstType_PRET); SetCurrentGCSPointer(GetCurrentGCSPointer() + 8); // Value in BTypeNext will be used to set PSTATE.BTYPE BTypeNext = '00'; constant boolean branch_conditional = FALSE; BranchTo(target, BranchType_RET, branch_conditional);
