2011-10-29Avoid assertion in processes with VM in bad shapeUlrich Drepper1-4/+4
2011-09-10Remove MALLOC_FAILURE_ACTION use in mallocUlrich Drepper1-19/+4
2011-09-10Simplify malloc initializationUlrich Drepper1-38/+31
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 Drepper1-1447/+203
Remove all kinds of unused configuration options and dead code.
2011-09-10Remove support for !USE___THREADUlrich Drepper1-13/+1

2010-08-16Replace divide and multiply with mask in sYSTRImAnton Blanchard1-1/+1
2010-05-06Fix race in free sanity check.Ulrich Drepper1-6/+9
2010-04-14Remove unintended change.Ulrich Drepper1-4/+0
2010-04-14Optimie x86-64 SSE4 memcmp for unaligned data.H.J. Lu1-0/+4
2010-04-08Fix possibly uninitilized variable handling.Ulrich Drepper1-0/+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.
2010-04-03One more sanity check in free.Ulrich Drepper1-1/+14
2010-04-03Fix set_max_fast in malloc.Ulrich Drepper1-1/+2

the real one.
2009-07-16Fix race in corruption check.Ulrich Drepper1-2/+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.
2009-07-16Use rel semantics of cas instead of acq semantics with full barrier before ↵Jakub Jelinek1-2/+1
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.
