23.2 Linker-Defined Symbols

The 32-bit linker defines several symbols that can be used in your C code development. Please see the MPLAB^® XC32 Assembler, Linker and Utilities User’s Guide (DS50002186) for more information.

The linker also defines the symbol _stack, which is used by the runtime start-up code to initialize the stack pointer. This symbol represents the starting address for the software stack.

All the above symbols are rarely required for most programs, but may assist you if you are writing your own runtime start-up code.
