BSL2N

Bitwise select with second input inverted.

Selects bits from the first source vector where the corresponding bit in the third source vector is '1', and from the inverted second source vector where the corresponding bit in the third source vector is '0'. The result is placed destructively in the destination and first source vector. This instruction is unpredicated.

BSL2N <Zdn>.D, <Zdn>.D, <Zm>.D, <Zk>.D

if !HaveSVE2() then UNDEFINED;
integer m = UInt(Zm);
integer k = UInt(Zk);
integer dn = UInt(Zdn);

Assembler Symbols

<Zdn>

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

<Zm>

Is the name of the second source scalable vector register, encoded in the "Zm" field.

<Zk>

Is the name of the third source scalable vector register, encoded in the "Zk" field.

Operation

CheckSVEEnabled();
bits(VL) operand1 = Z[dn];
bits(VL) operand2 = Z[m];
bits(VL) operand3 = Z[k];

Z[dn] = (operand1 AND operand3) OR (NOT(operand2) AND NOT(operand3));
