The linker is part of the GNU binutils, not gcc, and questions about it should be directed to the binutils@xxxxxxxxxxxxxx mailing list. See http://sourceware.org/binutils/. The map file does not tell you whether a symbol is a function. You can of course use objdump or readelf on the linked executable to find that out. The map file will tell you whether a symbol was defined by the linker: it will be in a section not associated with any input file, and will have a linker script command on it. E.g., 0x08049578 _end = . Ian
