Вот как это делает Microchip в своих GCC-based компиляторах XC (мануал приложен): 2.5.2 Absolute Addressing
Variables and functions can be placed at an absolute address by using the
__at() construct. Stack-based (auto and parameter) variables cannot use the
__at() specifier.
2.5.2.1 EXAMPLE
The following example shows two variables and a function being made absolute.
int scanMode __at(0x200);
const char keys[] __at(124) = { ’r’, ’s’, ’u’, ’d’};
__at(0x1000) int modify(int x) {
return x * 2 + 3;
}
2.5.2.2 DIFFERENCES
The 8-bit compilers have used an @ symbol to specify an absolute address.
The 16- and 32-bit compilers have used the
address attribute to specify an object’s address.

3.4.3.1 HOW DO I POSITION VARIABLES OR FUNCTIONS AT AN ADDRESS I NOMINATE?
Nudging the tool chain to allocate variables or functions in specific areas of memory can make it harder for the linker to do its job. Tools are provided to solve problems that may exist, but they should always be used carefully. For example, instead of fixing an object at a specific address (using the
address attribute or the
__at construct), it may be sufficient to group variables together using the
section attribute.
