The ebpf packages were somewhat neglected during the restructuring of the the repository and currently do not build. They were also a little awkward to use. So move them to ./projects for now until it matures. Signed-off-by: Rolf Neugebauer <rolf.neugebauer@docker.com>

/*
|
|
* Macros for manipulating "link sets". Link sets are arrays of pointers
|
|
* to objects, which are gathered up by the linker.
|
|
*
|
|
* Object format-specific code has provided us with the following macros:
|
|
*
|
|
* __link_set_add_text(set, sym)
|
|
* Add a reference to the .text symbol `sym' to `set'.
|
|
*
|
|
* __link_set_add_rodata(set, sym)
|
|
* Add a reference to the .rodata symbol `sym' to `set'.
|
|
*
|
|
* __link_set_add_data(set, sym)
|
|
* Add a reference to the .data symbol `sym' to `set'.
|
|
*
|
|
* __link_set_add_bss(set, sym)
|
|
* Add a reference to the .bss symbol `sym' to `set'.
|
|
*
|
|
* __link_set_decl(set, ptype)
|
|
* Provide an extern declaration of the set `set', which
|
|
* contains an array of pointers to type `ptype'. This
|
|
* macro must be used by any code which wishes to reference
|
|
* the elements of a link set.
|
|
*
|
|
* __link_set_start(set)
|
|
* This points to the first slot in the link set.
|
|
*
|
|
* __link_set_end(set)
|
|
* This points to the (non-existent) slot after the last
|
|
* entry in the link set.
|
|
*
|
|
* __link_set_count(set)
|
|
* Count the number of entries in link set `set'.
|
|
*
|
|
* In addition, we provide the following macros for accessing link sets:
|
|
*
|
|
* __link_set_foreach(pvar, set)
|
|
* Iterate over the link set `set'. Because a link set is
|
|
* an array of pointers, pvar must be declared as "type **pvar",
|
|
* and the actual entry accessed as "*pvar".
|
|
*
|
|
* __link_set_entry(set, idx)
|
|
* Access the link set entry at index `idx' from set `set'.
