2011-10-29Avoid assertion in processes with VM in bad shapeUlrich Drepper
2011-09-10Remove MALLOC_FAILURE_ACTION use in mallocUlrich Drepper
2011-09-10Simplify malloc initializationUlrich Drepper
Singificantly reduce the code needed at malloc initialization. In the process getpagesize is simplified by always initializing GLRO(dl_pagesize).
2011-09-10Simplify malloc codeUlrich Drepper
Remove all kinds of unused configuration options and dead code.

2010-10-24Fix perturbing in malloc on free.Ulrich Drepper
2010-08-16Replace divide and multiply with mask in sYSTRImAnton Blanchard

2010-04-14Remove unintended change.Ulrich Drepper
2010-04-14Optimie x86-64 SSE4 memcmp for unaligned data.H.J. Lu
2010-04-08Fix possibly uninitilized variable handling.Ulrich Drepper
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.
2010-04-03One more sanity check in free.Ulrich Drepper
2010-04-03Fix set_max_fast in malloc.Ulrich Drepper

the real one.
2009-07-16Fix race in corruption check.Ulrich Drepper
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.
2009-07-16Use rel semantics of cas instead of acq semantics with full barrier before ↵Jakub Jelinek
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.
