* Decouple the C Program Heap initializationSebastian Huber2020-10-011-44/+34
| | | | | | | Before this patch RTEMS_Malloc_Initialize() had a fixed dependency on _Workspace_Area. Introduce _Workspace_Malloc_initializer to have this dependency only if CONFIGURE_UNIFIED_WORK_AREAS is defined by the application configuration.
* Canonicalize config.h includeSebastian Huber2020-04-161-2/+2
| | | | | | | | Use the following variant which was already used by most source files: #ifdef HAVE_CONFIG_H #include "config.h" #endif
* bsps: Rework work area initializationSebastian Huber2020-02-041-16/+41
| | | | | | | | | | | | | | | | | | | | The work area initialization was done by the BSP through bsp_work_area_initialize(). This approach predated the system initialization through the system initialization linker set. The workspace and C program heap were unconditionally initialized. The aim is to support RTEMS application configurations which do not need the workspace and C program heap. In these configurations, the workspace and C prgram heap should not get initialized. Change all bsp_work_area_initialize() to implement _Memory_Get() instead. Move the dirty memory, sbrk(), per-CPU data, workspace, and malloc() heap initialization into separate system initialization steps. This makes it also easier to test the individual initialization steps. This change adds a dependency to _Heap_Extend() to all BSPs. This dependency will be removed in a follow up change. Update #3838.
* score: Introduce _Internal_error()Sebastian Huber2016-12-121-1/+1

* score: Remove fatal is internal indicatorSebastian Huber2016-12-091-5/+1
| | | | | | | | | The fatal is internal indicator is redundant since the fatal source and error code uniquely identify a fatal error. Keep the fatal user extension is internal parameter for backward compatibility and set it to false always. Update #2825.
* libcsupport: Delete malloc statisticsSebastian Huber2014-11-281-11/+0
| | | | | | | Use the heap handler statistics instead. Add heap walk option to MALLOC shell command. close #1367
* Change all references of rtems.com to rtems.org.Chris Johns2014-03-211-1/+1

* score: Rename _Internal_error_Occurred()Sebastian Huber2014-02-211-1/+1
| | | | Rename _Internal_error_Occurred() into _Terminate().
* score: Work area initialization API changeSebastian Huber2012-10-251-70/+45
| | | | | | | | | | | | The work areas (RTEMS work space and C program heap) will be initialized now in a separate step and are no longer part of rtems_initialize_data_structures(). Initialization is performed with tables of Heap_Area entries. This allows usage of scattered memory areas present on various small scale micro-controllers. The sbrk() support API changes also. The bsp_sbrk_init() must now deal with a minimum size for the first memory chunk to take the configured work space size into account.
* libcsupport: malloc_deferred_frees_initialize()Sebastian Huber2012-10-251-5/+0
| | | | Remove this function and statically initialize RTEMS_Malloc_GC_list.
* Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill2012-05-111-2/+0
| | | | | | | | | | | | Script does what is expected and tries to do it as smartly as possible. + remove occurrences of two blank comment lines next to each other after Id string line removed. + remove entire comment blocks which only exited to contain CVS Ids + If the processing left a blank line at the top of a file, it was removed.

| | | | | | | * libcsupport/src/malloc_initialize.c: After discussion with Till Straumann, revert the change from r1.12 to r1.13. This broke BSPs with sbrk() support once the libbsp sbrk() framework was enhanced. psim runs now.
