* fastlz.c: Unused value (CID #1399751)Ryan Long2021-04-081-1/+9
| | | | | | CID 1399751: Unused value in fastlz2_compress(). Closes #4341
* Fix -Wchar-subscripts warningsAschref Ben Thabet2020-08-201-2/+2
| | | | | | | The argument to the ctype functions must be an int and the value of the character must be representable as an unsigned char or equal to the value of the macro EOF. If the argument has any other value, the behavior is undefined.
* libdl: Add allocator check scriptChris Johns2020-05-061-0/+96
| | | | Use with the trace outout to check for allocation leaks.
* libdl/rap: Correctly check the return enum from rela callsChris Johns2020-05-051-4/+13
| | | | | | | | - The change from bool to an enum did not trip a compiler warning and only the rel path was changed. The rela path was missed so archs like SPARC failed. Updates #3969

* libdl: Do not access the ELF file while the allocator is locked.Chris Johns2019-05-0319-514/+1042
| | | | | | | | | | | | | - 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/alloc: Add a locking interface to the allocator.Chris Johns2019-02-203-5/+63
| | | | | | | | | | | | | - Allow an allocator to lock the allocations. This is needed to lock the heap allocator so the text and trampoline table are as close together as possible to allow for the largest possible object file size. - Update the default heap allocator to lock the heap allocator. - Update ELF loading to lock the allocator. Updates #3685
* libdl/rap: Add the section alloc call after section load was splitChris Johns2019-02-151-0/+6
| | | | Updates #3687
* libdl: Allocator does not unlock and lock memory on loading.Chris Johns2019-02-154-15/+90
| | | | Close #3692
* libdl: Add powerpc large memory and small data support.Chris Johns2019-02-0920-109/+1048
| | | | | | | | | | | | | | | | | - 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
* libdl: Add support for large memory programsChris Johns2019-02-098-413/+609
| | | | | | | | | | | | | | | - 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: Add support for trampolinesChris Johns2019-02-0914-125/+888
| | | | | | | | | | | | | - 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
* libdl: Fix the support for constructors and desctructors.Chris Johns2019-02-094-39/+91
| | | | | | | - 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 Johns2019-02-0910-445/+1846
| | | | | | | | | | | | | | - 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 Johns2018-11-226-124/+491
| | | | | | | | | | 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: Reindex unresolved names after removing used records.Chris Johns2018-11-221-20/+120
| | | | Updates #3194
* libdl: Manage the allocation of common uninitialised variables.Chris Johns2018-11-222-26/+187
| | | | | | | | | | | | | The use of separate text and data results in uninitialised variables being placed in the common section. There is no section in ELF for the common variables so the loader needs to create the section and allocate the variables in that section. This patch does that. The patch adds a second pass over the symbols. The issue can also be seen as a section 65522 error. Updates #3604

* Remove make preinstallChris Johns2018-01-2533-4686/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A speciality of the RTEMS build system was the make preinstall step. It copied header files from arbitrary locations into the build tree. The header files were included via the -Bsome/build/tree/path GCC command line option. This has at least seven problems: * The make preinstall step itself needs time and disk space. * Errors in header files show up in the build tree copy. This makes it hard for editors to open the right file to fix the error. * There is no clear relationship between source and build tree header files. This makes an audit of the build process difficult. * The visibility of all header files in the build tree makes it difficult to enforce API barriers. For example it is discouraged to use BSP-specifics in the cpukit. * An introduction of a new build system is difficult. * Include paths specified by the -B option are system headers. This may suppress warnings. * The parallel build had sporadic failures on some hosts. This patch removes the make preinstall step. All installed header files are moved to dedicated include directories in the source tree. Let @RTEMS_CPU@ be the target architecture, e.g. arm, powerpc, sparc, etc. Let @RTEMS_BSP_FAMILIY@ be a BSP family base directory, e.g. erc32, imx, qoriq, etc. The new cpukit include directories are: * cpukit/include * cpukit/score/cpu/@RTEMS_CPU@/include * cpukit/libnetworking The new BSP include directories are: * bsps/include * bsps/@RTEMS_CPU@/include * bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILIY@/include There are build tree include directories for generated files. The include directory order favours the most general header file, e.g. it is not possible to override general header files via the include path order. The "bootstrap -p" option was removed. The new "bootstrap -H" option should be used to regenerate the "headers.am" files. Update #3254.
