-Softmax is often used as the last activation function in a neural network - softmax(xi) = exp(xi)/(exp(x0) + exp(x1) + ... + exp(xn))). This step happens after the final low precision gemm computation, and it helps to have the softmax functionality that can be invoked as part of the lpgemm workflow. In order to support this, a new api, aocl_softmax_f32 is introduced as part of aocl_gemm. This api computes element-wise softmax of a matrix/vector of floats. This api invokes ISA specific vectorized micro-kernels (vectorized only when incx=1), and a cntx based mechanism (similar to lpgemm_cntx) is used to dispatch to the appropriate kernel.
