Introduce DL_LOOKUP_FOR_RELOCATE flag for _dl_lookup_symbol_x
|
||
|
|
|
||
|
|
This will allow changes in dependency processing during non-lazy
|
||
|
|
binding, for more precise processing of NODELETE objects: During
|
||
|
|
initial relocation in dlopen, the fate of NODELETE objects is still
|
||
|
|
unclear, so objects which are depended upon by NODELETE objects
|
||
|
|
cannot immediately be marked as NODELETE.
