INCP (vector)

.

Counts the number of true elements in the source predicate and then uses the result to increment all destination vector elements.

The predicate size specifier may be omitted in assembler source code, but this is deprecated and will be prohibited in a future release of the architecture.

Increment vector by count of true predicate elements.

Counts the number of true elements in the source predicate and then uses the result to increment all destination vector elements.

The predicate size specifier may be omitted in assembler source code, but this is deprecated and will be prohibited in a future release of the architecture.

INCP <Zdn>.<T>, <Pm>.<T>

if !HaveSVE() then UNDEFINED; if size == '00' then UNDEFINED; integer esize = 8 << UInt(size); integer m = UInt(Pm); integer dn = UInt(Zdn);

Assembler Symbols

<Zdn>

Is the name of the source and destination scalable vector register, encoded in the "Zdn" field.

<T> Is the size specifier, encoded in size:
size<T>
00RESERVED
01H
10S
11D
<T>

Is the size specifier, encoded in size:

size<T>
00RESERVED
01H
10S
11D
<Pm>

Is the name of the source scalable predicate register, encoded in the "Pm" field.

Operation

CheckSVEEnabled(); integer elements = VL DIV esize; bits(VL) operand1 = Z[dn]; bits(PL) operand2 = P[m]; bits(VL) result; integer count = 0; for e = 0 to elements-1 if ElemP[operand2, e, esize] == '1' then count = count + 1; for e = 0 to elements-1 Elem[result, e, esize] = Elem[operand1, e, esize] + count; Z[dn] = result;

Operational information

This instruction might be immediately preceded in program order by a MOVPRFX instruction. The MOVPRFX instruction must conform to all of the following requirements, otherwise the behavior of the MOVPRFX and this instruction is unpredictable:
