UQINCD (scalar) Unsigned saturating increment scalar by multiple of 64-bit predicate constraint element count Determines the number of active 64-bit elements implied by the named predicate constraint, multiplies that by an immediate in the range 1 to 16 inclusive, and then uses the result to increment the scalar destination. The result is saturated to the general-purpose register's unsigned integer range. The named predicate constraint limits the number of active elements in a single predicate to: A fixed number (VL1 to VL256) The largest power of two (POW2) The largest multiple of three or four (MUL3 or MUL4) All available, implicitly a multiple of two (ALL). Unspecified or out of range constraint encodings generate an empty predicate or zero element count rather than Undefined Instruction exception.
