vector.interleave

← vector dialect

Interleave two same-typed vectors along the template axis. Result positions with even coordinates along that axis come from the first operand, odd coordinates come from the second operand, and the result extent on that axis is doubled.

Examples

%r = vector.interleave<0> %lo, %hi : vector<16xi8>, vector<16xi8> -> vector<32xi8>

%r = vector.interleave<1> %a, %b : vector<4x8xi8>, vector<4x8xi8> -> vector<4x16xi8>
