Found Kernel is not rewritable!

[TJU-PanYizhe]

I tried KernelFaRer on gemm and syr2k kernel of PolyBenchC, but it showed "Found Kernel is not rewritable!"

Thanks for you interest in KernelFaRer.

That message might indicate that the matcher found a candidate for replacement but concluded that it would not be safe to replace it with a BLAS call (this might be a regression or a true positive).

Could you provide mode details (e.g. compilation command line and steps used to build KernelFaRer).

I will do my best to take a look at it ASAP.
