Why does applying the merge attribute to an array declared within an unrolled or partially unrolled loop create an unexpectedly wide memory using Intel® FPGA SDK for OpenCL version 19.1?


Due to a problem in the Intel® FPGA SDK for OpenCL version 19.1,  the merge attribute creates a wide memory with an array using unrolled or partially unrolled loop.


This problem is fixed beginning with the Intel®Quartus Prime Pro Edition software version 19.2.
