* Revert addtion of assertions in revision 1.99. These assertions causejasone2006-01-191-7/+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.

* Add a separate simple internal base allocator and remove base_arena, so thatjasone2006-01-161-151/+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().
* Define NO_TLS on ia64. The dynamic TLS implementation on ia64 ismarcel2006-01-161-0/+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:jasone2006-01-124-63/+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.
