ILINK supports two different types of symbols in the configuration file:

• Config symbols (define symbol directive)

  Config symbols:

  • are only used inside the linker configuration file, and their value never escapes the configuration file.

  • are evaluated when they are defined.

  • can only refer to constants and other exported or config symbols.

• Exported symbols (define exported symbol directive)

  Exported symbols are like config symbols, but their value can be accessed from your application, and they will be present in the final symbol table.
