* cpukit/libcsupport/src/[g-r]*: Change license to BSD-2Joel Sherrill2022-04-011-3/+22
| | | | Updates #3053.
* Return NULL for zero size allocationsSebastian Huber2021-05-061-0/+4
| | | | | | | | | | | | | | | In POSIX, zero size memory allocations are implementation-defined behaviour. The implementation has two options: https://pubs.opengroup.org/onlinepubs/9699919799/functions/malloc.html https://pubs.opengroup.org/onlinepubs/9699919799/functions/posix_memalign.html Linux and FreeBSD return a unique pointer for zero size memory allocations. Return NULL on RTEMS to more likely catch the use of a zero size memory area by erroneous applications. Update #4390.
* 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
* malloc: Add _Malloc_System_state()Sebastian Huber2016-02-251-16/+1
| | | | | | | | | | Replace malloc_is_system_state_OK() with _Malloc_System_state() to allow early allocations, e.g. in bsp_start(). Here the _Thread_Executing is NULL, thus an _API_Mutex_Lock() would lead to a NULL pointer access. Move malloc() support code to general case rtems_heap_allocate_aligned_with_boundary(). Use rtems_heap_allocate_aligned_with_boundary() to avoid duplicated code.
* libcsupport: Delete malloc statisticsSebastian Huber2014-11-281-6/+0
| | | | | | | Use the heap handler statistics instead. Add heap walk option to MALLOC shell command. close #1367
* libcsupport: malloc_is_system_state_OK()Sebastian Huber2014-11-251-4/+1
| | | | Move system state check to malloc_is_system_state_OK().

* 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.

In other words, the RTEMS Workspace and C Program Heap are the same pool of memory.

* libcsupport/Makefile.am, libcsupport/include/rtems/malloc.h, libcsupport/src/malloc_walk.c, libcsupport/src/posix_memalign.c, libcsupport/src/realloc.c, score/src/heapwalk.c: Add rtems_memalign as helper and as exposed nmemalign variant with few restrictions. Also turn on compilation of _Heap_Walk but make forced calls to it conditionally compiled. This should allow more flexibility to the user as to run-time checking of the heap. * libcsupport/src/rtems_memalign.c: New file.
