Expression evaluation allocates memory for storing intermediate data during evaluation. For it to work properly it has to be allocated within target's available address space, for example within first 0xFFFF bytes for the 16-bit MSP430. The memory for such targets can be very tightly packed, but not all targets support GetMemoryRegionInfo API to pick an unused region, like MSP430 with MSPDebug GDB server.

These settings allow the programmer to manually pick precisely where and how much memory to allocate for expression evaluation in order not to overlap with existing data in process memory.
