* Make zero size allocation result consistentSebastian Huber2021-05-041-6/+0
| | | | | | | | | | | | | | | | | | 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.

* malloc: Add _Malloc_System_state()Sebastian Huber2016-02-251-30/+3
| | | | | | | | | | 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 Huber2014-11-281-8/+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().

* score: Work area initialization API changeSebastian Huber2012-10-251-2/+1
| | | | | | | | | | | | 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.
* Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill2012-05-111-2/+0

The problem is that realloc() can neither grow nor shrink efficiently the current memory region without support from underlying heap/region modules. The patch introduces one new routine for each of heap and region modules, _Heap_Resize_block(), and rtems_region_resize_segment(), respectively, and uses the latter to optimize realloc(). The implementation of _Heap_Resize_block() lead to changing of the heap allocation strategy: now the heap manager, when splits larger free block into used and new free parts, makes the first part of the block used, not the last one as it was before. Due to this new strategy, _Heap_Resize_block() never needs to change the user pointer. Caveat: unlike previous heap implementation, first few bytes of the contents of the memory allocated from the heap are now almost never all zero. This can trigger bugs in client code that have not been visible before this patch. * libcsupport/src/malloc.c (realloc): try to resize segment in place using new rtems_region_resize_segment() routine before falling back to the malloc()/free() method. * score/src/heap.c: (_Heap_Initialize): change initial heap layout to reflect new allocation strategy of using of the lower part of a previously free block when splitting it for the purpose of allocation.

* Port of RTEMS to the Texas Instruments C3x/C4x DSP families includingJoel Sherrill2000-07-261-2/+2
| | | | | | | | | | | a BSP (c4xsim) supporting the simulator included with gdb. This port was done by Joel Sherrill and Jennifer Averett of OAR Corporation. Also included with this port is a space/time optimization to eliminate FP context switch management on CPUs without hardware or software FP. An issue with this port was that sizeof(unsigned32) = sizeof(unsigned8) on this CPU. This required addressing alignment checks and assumptions as well as fixing code that assumed sizeof(unsigned32) == 4.

* This is another pass at making sure that nothing outside the BSPJoel Sherrill1999-11-051-2/+1
| | | | | | | | | | | | unnecessarily uses any variables defined by the BSP. On this sweep, use of BSP_Configuration and Cpu_table was eliminated. A significant part of this modification was the addition of macros to access fields in the RTEMS configuration structures. This is necessary to strengthen the division between the BSP independent parts of RTEMS and the BSPs themselves. This started after comments and analysis by Ralf Corsepius <corsepiu@faw.uni-ulm.de>.
* Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:Joel Sherrill1999-08-181-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here is another fix, which addresses a few more or less severe bugs in configuration and unix/posix: * Configuration fix: c/src/lib/configure.in didn't handle RDBG correctly * Configuration fix: make depend was non-functional in c/src/lib/libc/Makefile.in * Configuration fix: stray comment removed from aclocal/target.m4 * RTEMS fix: termios support for unix/posix now uses the host's headers only (was completely broken). - Don't install RTEMS's newlib sys/termios.h for unix (sys/termios.h apparently is a newlib specific header) - To be able to compile RTEMS's termios.c with glibc2.1, glibc-2.1 needs __USE_MISC, which is a private define from gcc's features.h, being defined only when _BSD_SOURCE of _SVID_SOURCE is defined. RTEMS's termios apparently implements BSD, thus -D_BSD_SOURCE was added to Linux-posix.cfg. - Conflicting definitions for __USE_MISC and _BSD_SOURCE inside of RTEMS codes removed due to definition of _BSD_SOURCE on the toplevel. This fix has been tested with linux/posix (primary glibc2.1 native), linux/posix (secondary libc5 native), sh/gensh1, i386/pc386 and a couple of other bsp's/CPU. To apply: cd <srcdir> patch -p1 < rtems-rc-19990709-9.diff and aclocal -I aclocal && automake && autoconf cd c/src/lib; autoconf or ./autogen
