If you want the variable a to be located at a specific address, then the normal approach in gcc would be to use a variable attribute. To be clear, gcc does not support any such variable attribute at present. In a conventional Unix environment, I'm not sure how that could be implemented. In particular I don't think there would be any way to implement it for an initialized variable. The usual way to put a variable at a specific memory address would be to use an attribute to put the variable in a specific section and to use a linker script to put that section at a specific address.
