Specifies that an input section defining symbol is to be retained during unused section elimination. If multiple definitions of symbol exist, armlink generates an error message.

For example, you might use --keep=int_handler.

To keep all sections that define a symbol ending in _handler, use --keep=*_handler.

Specifies that section from object is to be retained during unused section elimination. If a single instance of section is generated, you can omit section, for example, file.o(). Otherwise, you must specify section.

For example, to keep the vect section from the vectors.o object use: --keep=vectors.o(vect)

To keep all sections from the vectors.o object where the first three characters of the name of the sections are vec, use:--keep=vectors.o(vec*)

Specifies that the single input section from object is to be retained during unused section elimination. If you use this short form and there is more than one input section in object, the linker generates an error message.

For example, you might use --keep=dspdata.o.

To keep the single input section from each of the objects that has a name starting with dsp, use --keep=dsp*.o.
