Hi Tobias,

I've added the GEMM results you asked.

<h4>High-Performance Generalized Matrix Multiplication</h4>
Polly automatically detects and optimizes generalized matrix
multiplication, the computation C &larr; &alpha; &otimes; C &oplus; &beta;
&otimes; A &otimes; B, where A, B, and C are three appropriately sized
matrices, &oplus; and &otimes; operations are originating from the
corresponding matrix semiring, and &alpha; and &beta; are constants, and
beta is not equal to zero. It allows to obtain the highly optimized form
structured similar to the expert implementation of GEMM that can be found
in GotoBLAS and its successors.
