Why does array declared inside an unrolled loop not replicated as a memory?

    Intel® FPGA SDK for OpenCL™ Pro Edition
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

Due to a problem in the Intel® FPGA SDK for OpenCL version 19.3, an array declared inside an unrolled loop will not be replicated as a memory. Instead it gets connected to multiple load store units which causes a stallable structure.
