EORBT

Interleaving exclusive OR (bottom, top).

Interleaving exclusive OR between the even-numbered elements of the first source vector register and the odd-numbered elements of the second source vector register, placing the result in the even-numbered elements of the destination vector, leaving the odd-numbered elements unchanged. This instruction is unpredicated.

EORBT <Zd>.<T>, <Zn>.<T>, <Zm>.<T>

if !HaveSVE2() then UNDEFINED; integer esize = 8 << UInt(size); integer n = UInt(Zn); integer m = UInt(Zm); integer d = UInt(Zd); integer sel1 = 0; integer sel2 = 1;

Assembler Symbols

<Zd>

Is the name of the destination scalable vector register, encoded in the "Zd" field.

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

Is the name of the first source scalable vector register, encoded in the "Zn" field.

<Zm>

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

Operation

CheckSVEEnabled(); integer elements = VL DIV (2 * esize); bits(VL) operand1 = Z[n]; bits(VL) operand2 = Z[m]; bits(VL) result = Z[d]; for e = 0 to elements-1 bits(esize) element1 = Elem[operand1, 2*e + sel1, esize]; bits(esize) element2 = Elem[operand2, 2*e + sel2, esize]; Elem[result, 2*e + sel1, esize] = element1 EOR element2; Z[d] = result;
