2019-08-04libdl/arm: Add support for ARM trampolinesChris Johns
Closes #3776
2019-07-28libdl/arm: Fix ARM mode trampoline parsing of relocsChris Johns
- No need to dump globals syms in test dl01 when tracing Closes #3775
2019-05-03libdl: Do not access the ELF file while the allocator is locked.Chris Johns
- 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
2019-02-09libdl: Add powerpc large memory and small data support.Chris Johns
- Add support for architecure sections that can be handled by the architecture back end. - Add trampoline/fixup support for PowerPC. This means the PowerPC now supports large memory loading of applications. - Add a bit allocator to manage small block based regions of memory. - Add small data (sdata/sbss) support for the PowerPC. The support makes the linker allocated small data region of memory a global resource available to libdl loaded object files. Updates #3687 Updates #3685
2019-02-09libdl: Add support for large memory programsChris Johns
- 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
2019-02-09libdl: Add support for trampolinesChris Johns
- Trampolines or fixups for veneers provide long jump support for instruciton sets that implement short relative address branches. The linker provides trampolines when creating a static image. This patch adds trampoline support to libdl and the ARM architecture. - The dl09 test requires enough memory so modules are outside the relative branch instruction ranges for the architecture. Updates #3685
2019-02-09libdl: Fix the support for constructors and desctructors.Chris Johns
- Fix the handling of pending objects. - Add a constructor flags in objects to track then being called. Closes #2921
2018-04-12libdl: Remove _t from all structures as this is reserved for the standardsChris Johns
2017-12-13libdl: Include <rtems/rtl/rtl-*.h>Sebastian Huber
Prepare for header file move to common include directory. Update #3254.
2017-08-25Include missing <string.h>Sebastian Huber
Update #2133.
2016-12-14libdl: Add C++ exception support to loaded modules.Chris Johns
This has been tested on SPARC, i386, PowerPC and ARM. Closes #2767.
2016-09-08libdl: Add ARM C++ relocation record support.Chris Johns
Closes #2767
2014-10-31cpukit: Add libdl with the Runtime Loader (RTL) code.Chris Johns
This is a merge of the RTL project.
