* cpukit/libcsupport/src/[g-r]*: Change license to BSD-2Joel Sherrill2022-04-011-3/+22
| | | | Updates #3053.
* Check the alignment in posix_memalign() earlierSebastian Huber2021-05-071-4/+4
| | | | | | | Make sure all conditions to do a proper memory allocation are satisfied before a zero size memory allocation is performed. Update #4390.
* 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.
* libc: Reimplement posix_memlign()Sebastian Huber2021-05-061-7/+22
| | | | | | | | Move all error checks into posix_memalign() so that the returned memory pointer is set to NULL under all error conditions except memptr == NULL. Use parameter names of POSIX documentation.
* 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
* 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
* Change all references of rtems.com to rtems.org.Chris Johns2014-03-211-1/+1

* libcsupport: Doxygen Enhancement Task #3Mathew Kallada2012-12-081-2/+7

* 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.
* 2008-01-31 Joel Sherrill <joel.sherrill@OARcorp.com>Joel Sherrill2008-01-311-2/+0
| | | | * libcsupport/src/posix_memalign.c: Remove warning.
* 2008-01-29 Joel Sherrill <joel.sherrill@OARcorp.com>Joel Sherrill2008-01-291-60/+4
| | | | | | | | | | | * 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.
* 2008-01-09 Joel Sherrill <joel.sherrill@oarcorp.com>Joel Sherrill2008-01-091-1/+1

Add plugin for dirtying allocated memory to assist in debugging. Clean up comments and spacing as needed. * libcsupport/src/malloc_dirtier.c: New file.
* 2007-12-19 Joel Sherrill <joel.sherrill@OARcorp.com>Joel Sherrill2007-12-191-0/+102

Split out management of deferred frees to subroutines. * libcsupport/src/malloc_deferred.c, libcsupport/src/posix_memalign.c: New files.
