…enerates vector.extract + vector.add + vector.insert, need vector.transfer_Write instead.
This is partial fix, the program fails for out of Program memory on a core. 1. solves the reduction legalizer issue. 2. Converts the transfer_reads into loads 3. Applies 2D->1D flattening pattern on vector type. 4. Solves stack size problem by bumping the stack size.
1. Selected appropriate tile sizes. Peano vectorizes for <32xbf16> we choose the tile sizes such that we always generate the legal shapes. 2. found the bounds for both bf16 and f32 which work. 3. Tested the patch and cleaned up the patterns.
