* Revert addtion of assertions in revision 1.99. These assertions causeJason Evans2006-01-191-7/+0
| | | | | | | | | problems in cases where regions are faked up for the purposes of red-black tree searches, since those faked region headers reside on the stack, rather than in a malloc chunk. Notes: svn path=/head/; revision=154557

| | | | | | | | internal allocation does not rely on recursive arena use (base_arena was removed in revision 1.95). Notes: svn path=/head/; revision=154555

| | | | | | | | | | | allowing the error to be fatal. Move a label in order to make sure to properly handle errors in malloc(0). Reported by: Alastair D'Silva, Saneto Takanori Notes: svn path=/head/; revision=154546
* Add a separate simple internal base allocator and remove base_arena, so thatJason Evans2006-01-161-151/+175
| | | | | | | | | | | | | there is never any need to recursively call the main allocation functions. Remove recursive spinlock support, since it is no longer needed. Allow chunks to be as small as the page size. Correctly propagate OOM errors from arena_new(). Notes: svn path=/head/; revision=154421
* Define NO_TLS on ia64. The dynamic TLS implementation on ia64 isMarcel Moolenaar2006-01-161-0/+1
| | | | | | | | | | | | broken for non-threaded shared processes in that __tls_get_addr() assumes the thread pointer is always initialized. This is not the case. When arenas_map is referenced in choose_arena() and it is defined as a thread-local variable, it will result in a SIGSEGV. PR: ia64/91846 (describes the TLS/ia64 bug).

* In preparation for a new malloc implementation:Jason Evans2006-01-124-63/+156
| | | | | | | | | | | | | | | | * Add posix_memalign(). * Move calloc() from calloc.c to malloc.c. Add a calloc() implementation in rtld-elf in order to make the loader happy (even though calloc() isn't used in rtld-elf). * Add _malloc_prefork() and _malloc_postfork(), and use them instead of directly manipulating __malloc_lock.
