Hi, These 3 patches fix 3 issues in libdl.
1. The first patch adds support for common variables. I suspect this started to happen when we switch to separate text and data sections for functions. Libdl now allocates the address of uninitialised variables when loading. 2. A bug in the post loading unresolved symbol handling has been fixed. Unresolved symbols are resolved when the object file with a symbol is loaded. The symbol names and relocation records are held in a global pool and symbol name indexes were not reindexed when an unresolved symbol was resolved and removed. 3. Object module dependency tracking has been added. A loaded object file referenced by another object file cannot be unloaded until the dependent object module is unloaded. Object modules that depend on each other cannot be unloaded, there is not practicable way to do this. This change internally moves reloc process to 2 phases, something that will be needed for relocation fixups. Notes: 1. I am yet to visit RAP loading. I see an issue with dl06 on ARM. 2. These changes may work on 4.11, I have not tried to back port them and that task is not a current focus for me. If you do back port them please send me a copy.
