SVE

REV <Zd>.<T>, <Zn>.<T>

if !HaveSVE() then UNDEFINED; integer esize = 8 << UInt(size); integer n = UInt(Zn); integer d = UInt(Zd);

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>
00 B
01 H
10 S
11 D
<Zn>

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

Operation

CheckSVEEnabled(); bits(VL) operand = Z[n]; bits(VL) result = Reverse(operand, esize); Z[d] = result;
