<Xn>

Is the 64-bit name of the general-purpose register holding the address to be branched to, encoded in the "Rn" field.

Operation

bits(64) target = X[n, 64]; // Value in BTypeNext will be used to set PSTATE.BTYPE if InGuardedPage then if n == 16 || n == 17 then BTypeNext = '01'; else BTypeNext = '11'; else BTypeNext = '01'; BranchTo(target, BranchType_INDIR, FALSE);
