A +linker set consists of +@itemize @bullet +@item dedicated input sections for the linker (e.g. @code{.ctors} and +@code{.ctors.*} in the case of global constructors), +@item a begin marker (e.g. provided by @code{crtbegin.o}, and +@item an end marker (e.g. provided by @code{ctrend.o}). +@end itemize +A module may place a certain data item into the dedicated input section. The +linker will collect all such data items in this section and creates a begin and +end marker. The initialization code can then use the begin and end markers to +find all the collected data items (e.g. pointers to initialization functions). + +In the linker command file of the GNU linker we need the following output +section descriptions. +@example +@group +/* To be placed in a read-only memory region */ +.rtemsroset : @{ + KEEP (*(SORT(.rtemsroset.*))) +@} + +/* To be placed in a read-write memory region */ +.rtemsrwset : @{ + KEEP (*(SORT(.rtemsrwset.*))) +@} +@end group +@end example +The @code{KEEP()} ensures that a garbage collection by the linker will not +discard the content of this section. This would normally be the case since the +linker set items are not referenced directly. The @code{SORT()} directive +sorts the input sections lexicographically. Please note the lexicographical +order of the @code{.begin}, @code{.content} and @code{.end} section name parts +in the RTEMS linker sets macros which ensures that the position of the begin +and end markers are right. + +So, what is the benefit of using linker sets to initialize modules? It can be +used to initialize and include only those RTEMS managers and other components +which are used by the application. For example, in case an application uses +message queues, it must call @code{rtems_message_queue_create()}. In the +module implementing this function, we can place a linker set item and register +the message queue handler constructor. Otherwise, in case the application does +not use message queues, there will be no reference to the +@code{rtems_message_queue_create()} function and the constructor is not +registered, thus nothing of the message queue handler will be in the final +executable. + +For an example see test program @file{sptests/splinkersets01}. + +@section Directives + +@macro linkersetsset +The @code{set} parameter itself must be a valid C designator on which no macro +expansion is performed. It uniquely identifies the linker set. +@end macro + +@macro linkersetstype +The @code{type} parameter defines the type of the linker set items.
