[U-Boot-Users] Are gnu liker scripts available for C files?

Hello guys, I know, to implement XIP(eXecute In Place) on linux, read-only data and read-writable data of linux have to be splitted by some certain means, say, by way of using gnu linker scripts. Yes, gnu linker scripts are available to assemble language, but what about C files? Can the scritps separate the two types of data in C files? You know, C source files don't have diretives, like "AREA", "DATA" and "CODE", as assemble source files do. Any reply is appreciated.
