Description
https://github.com/intel/graph-compiler/actions/runs/10463928001/job/28976702848?pr=161
Here is a reproducible module
module {

%cst = arith.constant 0.000000e+00 : bf16
%0 = tensor.empty() : tensor<16x4xbf16>
%1 = linalg.fill ins(%cst : bf16) outs(%0 : tensor<16x4xbf16>) -> tensor<16x4xbf16>
%2 = linalg.matmul {cast = #linalg.type_fn<cast_signed>} ins(%arg0, %arg1 : tensor<16x4096xbf16>, tensor<4096x4xbf16>) outs(%1 : tensor<16x4xbf16>) -> tensor<16x4xbf16>
return %2 : tensor<16x4xbf16>
}
