XAFLAG Convert floating-point condition flags from external format to Arm format This instruction converts the state of the PSTATE.{N,Z,C,V} flags from an alternative representation required by some software to a form representing the result of an Arm floating-point scalar compare instruction. 1 1 0 1 0 1 0 1 0 0 0 0 0 0 0 0 0 1 0 0 (0) (0) (0) (0) 0 0 1 1 1 1 1 1 XAFLAG if !IsFeatureImplemented(FEAT_FlagM2) then EndOfDecode(Decode_UNDEF); end; let n : bit = NOT(PSTATE.C) AND NOT(PSTATE.Z); let z : bit = PSTATE.Z AND PSTATE.C; let c : bit = PSTATE.C OR PSTATE.Z; let v : bit = NOT(PSTATE.C) AND PSTATE.Z; PSTATE.N = n; PSTATE.Z = z; PSTATE.C = c; PSTATE.V = v; 2026-03-12 12:23:09 2025-09_rel_asl1
