6.6.1.7 -mno-eds-warn

On some devices, there is a possibility that the stack will reside in EDS (extended data space) memory (above 0x8000), though this allocation is disabled by default in the linker. If the stack is located in this area, then taking the address of an auto variable would require an __eds__ pointer. As the compiler does not know where the stack will be located, the default is to be conservative and warn if the address of an auto is taken and not used as an __eds__ pointer. This option disables the warning.
