* Remove MALLOC_FAILURE_ACTION use in mallocUlrich Drepper2011-09-101-19/+4
|
* Simplify malloc initializationUlrich Drepper2011-09-101-38/+31
| | | | | | Singificantly reduce the code needed at malloc initialization. In the process getpagesize is simplified by always initializing GLRO(dl_pagesize).
* Simplify malloc codeUlrich Drepper2011-09-101-1447/+203
| | | | Remove all kinds of unused configuration options and dead code.

|
* Fix possibly uninitilized variable handling.Ulrich Drepper2010-04-081-0/+1
| | | | | | If malloc errors are ignored (which say aren't by default and never should be) malloc in the old, slow form might use an uninitialized variable.

* Fix race in corruption check.Ulrich Drepper2009-07-161-2/+23
| | | | | | With atomic fastbins the checks performed can race with concurrent modifications of the arena. If we detect a problem re-do the test after getting the lock.

| | | | | | | | | | | it in _int_free The following patch fixes catomic_compare_and_exchange_*_rel definitions (which were never used and weren't correct) and uses catomic_compare_and_exchange_val_rel in _int_free. Comparing to the pre-2009-07-02 --enable-experimental-malloc state the generated code should be identical on all arches other than ppc/ppc64 and on ppc/ppc64 should use lwsync instead of isync barrier.
