|
|
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.

help

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.

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.
