TRN1, TRN2 (predicates)

Interleave even or odd elements from two predicates

This instruction interleaves alternating even or odd-numbered elements from the first and second source predicates, and places the values in the destination predicate. This instruction is unpredicated.

It has encodings from 2 classes: Even and Odd

Even
(FEAT_SVE || FEAT_SME)

Decode for this encoding

if !IsFeatureImplemented(FEAT_SVE) && !IsFeatureImplemented(FEAT_SME) then EndOfDecode(Decode_UNDEF); end; let esize : integer{} = 8 << UInt(size); let n : integer = UInt(Pn); let m : integer = UInt(Pm); let d : integer = UInt(Pd); let part : integer = 0;

Odd
(FEAT_SVE || FEAT_SME)

Decode for this encoding

if !IsFeatureImplemented(FEAT_SVE) && !IsFeatureImplemented(FEAT_SME) then EndOfDecode(Decode_UNDEF); end; let esize : integer{} = 8 << UInt(size); let n : integer = UInt(Pn); let m : integer = UInt(Pm); let d : integer = UInt(Pd); let part : integer = 1;
