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

SVE

INCP <Xdn>, <Pm>.<T>

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

Assembler Symbols

<Xdn>

Is the 64-bit name of the source and destination general-purpose register, encoded in the "Rdn" field.

<Pm>

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

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

Operation

CheckSVEEnabled(); integer elements = VL DIV esize; bits(64) operand1 = X[dn]; bits(PL) operand2 = P[m]; integer count = 0; for e = 0 to elements-1 if ElemP[operand2, e, esize] == '1' then count = count + 1; X[dn] = operand1 + count;
