* Make zero size allocation result consistentSebastian Huber2021-05-041-4/+4
| | | | | | | | | | | | | | | | | | The zero size allocations had no consistent behaviour in RTEMS. For example, malloc( 0 ) returned NULL and posix_memalign( &p, align, 0 ) returned in p a unique pointer (or NULL if no memory is available). 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. Use this approach for RTEMS as well throughout the memory allocation directives Close #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: Fix early realloc() allocationSebastian Huber2016-04-061-45/+48

* libcsupport: Delete malloc statisticsSebastian Huber2014-11-281-4/+0
| | | | | | | Use the heap handler statistics instead. Add heap walk option to MALLOC shell command. close #1367

* score: Create object implementation headerSebastian Huber2013-07-261-0/+1
| | | | | | Move implementation specific parts of object.h and object.inl into new header file objectimpl.h. The object.h contains now only the application visible API.

* libcsupport: Do not use _ISR_Nest_levelSebastian Huber2013-07-181-3/+0
| | | | | The _Thread_Dispatch_is_enabled() is false if _ISR_Nest_level is not equal to zero.
* score: Add and use _Thread_Dispatch_is_enabled()Sebastian Huber2013-06-141-1/+1
| | | | | Delete _Thread_Dispatch_in_critical_section() and _Thread_Is_dispatching_enabled().

* 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.
