BR Branch to register This instruction branches unconditionally to an address in a register, with a hint that this is not a subroutine return. 1 1 0 1 0 1 1 0 0 0 0 1 1 1 1 1 0 0 0 0 0 0 0 0 0 0 0 BR <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. constant 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'; constant boolean branch_conditional = FALSE; BranchTo(target, BranchType_INDIR, branch_conditional);
