How to force memory generated in clusters to be implemented in MLAB in FPGA OpenCL v19.1

[DongWang-BJTU]

There is new feature in FPGA OpenCL v19.1 that one could force memory blocks to be implemented in MLAB or M20K as described in the guide:

But it only works on variables that are explicitly defined in the code. Some time the compiler will generate lots of memory in the clusters like follows:

When I use multiple kernels, it became very costly in M20K.

So is there any way that one could force such memory to be implemented in MLAB rather than M20K ?

I also tried v18.1.1, it seems that v18.1.1 will implement the same memory in MLAB instead of M20K.
