As the summary says, when compiling with --speculate_loads=auto, the linker may create zero-filled fill sections where padding is needed, whether or not the padded section itself contains data. That means that even though the section itself is not loaded to the target, the fill sections are. If there is a memory map in which it is important not to write there, this behavior can mess it up.
