2020-04-16Canonicalize config.h includeSebastian Huber
Use the following variant which was already used by most source files: #ifdef HAVE_CONFIG_H #include "config.h" #endif
2020-02-04bsps: Rework work area initializationSebastian Huber
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.
2016-12-12score: Introduce _Internal_error()Sebastian Huber
2016-12-09score: Remove fatal is internal indicatorSebastian Huber
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.
2014-11-28libcsupport: Delete malloc statisticsSebastian Huber
Use the heap handler statistics instead. Add heap walk option to MALLOC shell command. close #1367

2014-02-21score: Rename _Internal_error_Occurred()Sebastian Huber
Rename _Internal_error_Occurred() into _Terminate().
2012-10-25score: Work area initialization API changeSebastian Huber
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.
2012-10-25libcsupport: malloc_deferred_frees_initialize()Sebastian Huber
Remove this function and statically initialize RTEMS_Malloc_GC_list.
2012-05-11Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill
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.

PR 1924/cpukit * sapi/include/rtems/config.h: New fields stack_space_size, unified_work_area, and stack_allocator_avoids_work_space in rtems_configuration_table. * sapi/include/confdefs.h: Removed rtems_unified_work_area (this is now part of the Configuration). Separate work space and stack space estimate. Added CONFIGURE_TASK_STACK_ALLOCATOR_AVOIDS_WORK_SPACE configuration option. * libmisc/shell/main_wkspaceinfo.c, score/src/wkspace.c, libcsupport/src/malloc_initialize.c: Update due to API changes.

* 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.
