| Include the reset vector stub, which enables instruction/data caches |
| and then jumps to __start. This code is typically located at the very |
| beginning of flash memory. You may need to omit this if using the |
| nios2-download tool since it refuses to load data anywhere other than |
| RAM. |

| Have exceptions print additional useful debugging information in |
| human-readable form, at the expense of code size. For example, |
| the cause code for an exception will be supplemented by a string |
| describing what that cause code means. |

| bool "Global data global pointer references" |
| help |
| Use global pointer relative offsets for small globals declared |
| anywhere in the executable. Note that if any small globals that are put |
| in alternate sections they must be declared |
| in headers with proper __attribute__((section)) or the linker will |
| error out. |

| Use GP relative access for all data in the program, not just |
| small data. Use this if your board has 64K or less of RAM. |
