* Canonicalize config.h includeSebastian Huber2020-04-161-1/+1
| | | | | | | | Use the following variant which was already used by most source files: #ifdef HAVE_CONFIG_H #include "config.h" #endif
* libdl: Do not access the ELF file while the allocator is locked.Chris Johns2019-05-031-14/+17
| | | | | | | | | | | | | - Load symbols before allocation. - Parse reloc records and place any reloc recs in a cache to use while the allocator is locked. - Relocate symbols after section allocation. - Split section loading into allocation/locating and loading. - Update all arch back-ends with a new reloc interface to control tramp handling. - Add `-a` and `-t` to the object list shell command. Closes #3741
* libdl: Add support for large memory programsChris Johns2019-02-091-1/+9
| | | | | | | | | | | | | | | - Add trampolines to support relocs that are out of range on support architectures. - Support not loading separate text/data sections in an object file if the symbol provided in the section is a duplicate. A base image may have pulled in part of an object and another part needs to be dynamically loaded. - Refactor the unresolved handling to scale to hundreds of unresolved symbols when loading large number of files. Updates #3685
* libdl: Fix the support for constructors and desctructors.Chris Johns2019-02-091-33/+60
| | | | | | | - Fix the handling of pending objects. - Add a constructor flags in objects to track then being called. Closes #2921
* libdl: Add symbol searching and loading from archives.Chris Johns2019-02-091-58/+219
| | | | | | | | | | | | | | - Load archive symbol tables to support searching of archives for symbols. - Search archive symbols and load the object file that contains the symbol. - Search the global and archives until all remaining unresolved symbols are not found. Group the loaded object files in the pending queue. - Run the object file and loaded dependents as a group before adding to the main object list. - Remove orphaned object files after references are removed. Updates #3686
* libdl: Add object file dependencies to track referencesChris Johns2018-11-221-1/+47
| | | | | | | | | | Tracking references lets us manage when an object file can be unloaded. If an object file has references to it, it cannot be unloaded. Modules that depend on each other cannot be unloaded. Updates #3605
* libdl: Remove _t from all structures as this is reserved for the standardsChris Johns2018-04-121-30/+30

* libdl: Add C++ exception support to loaded modules.Chris Johns2016-12-141-1/+32
| | | | | | This has been tested on SPARC, i386, PowerPC and ARM. Closes #2767.
* Replace www.rtems.com with www.rtems.orgSebastian Huber2015-03-201-1/+1
