Error: gemmKernel.hpp with tagAB expected 4, have 5 arguments

[miniskar]

I am getting compilation error for gemm. I have verified the error in master and several release tags also.

Here are the commands to reproduce

cd Vitis_Libraries/blas/L3/tests/gemm/streamingKernel/gemm_float
make run TARGET=hw DEVICE=/opt/xilinx/platforms/xilinx_u250_gen3x16_xdma_3_1_202020_1/xilinx_u250_gen3x16_xdma_3_1_202020_1.xpfm

Vitis compilation error:

Hi, I have checked-out vmayoral/Vitis_Libraries. However, I couldn't get the successful build.

It seems like it is having multiple issues.

I have tested the fix provided in master branch. Thank you for the fix. It is working good for hw_emu and hw mode. However, it is throwing error in sw_emu mode.

@miniskar , this case is released accidentally without testing and will be widthdrawn.
