2013-09-30erts: Refactor the ASSERT macroSverker Eriksson
Introduce unconditional ERTS_ASSERT and use that for both ASSERT and ASSERT_EXPR.
2013-06-19erts: Add new allocator strategy aoffcbfSverker Eriksson
with better performance than aoffcaobf as we don't have to rearrange the search tree when there are blocks of equal size.
2013-06-03erts: Remove unnecessary flag arguments in allocatorsSverker Eriksson
A cleanup after SBMBC was removed.
2013-06-03erts: Remove SBMBC allocatorSverker Eriksson
2013-06-03erts: Change naive list to rb-tree of carriers in AOFF allocatorSverker Eriksson
and add new callbacks add_mbc(), remove_mbc() and largest_fblk_in_mbc() for carrier migration.
2013-06-03erts: Make carrier header sizes customizableSverker Eriksson
This is a modified partial revert of 2ab1d972f6fd37c17b05
2013-06-03erts: Add "bestfit within carrier" for aoff allocator (aoffcbf)Sverker Eriksson
2013-05-06erts: Change some more 'long' to pointer sized int (ErlDrvUInt)Sverker Eriksson

2012-11-21erts: Make carrier header sizes compile time constantsSverker Eriksson
No allocator strategy is using customized carrier headers anyway.
2012-11-15erts: Add carrier pointer to header of free blockSverker Eriksson
2012-11-15erts: Add carrier offset to internal allocation headersSverker Eriksson
2011-11-13Optimize memory allocationRickard Green
A number of memory allocation optimizations have been implemented. Most optimizations reduce contention caused by synchronization between threads during allocation and deallocation of memory. Most notably: * Synchronization of memory management in scheduler specific allocator instances has been rewritten to use lock-free synchronization. * Synchronization of memory management in scheduler specific pre-allocators has been rewritten to use lock-free synchronization. * The 'mseg_alloc' memory segment allocator now use scheduler specific instances instead of one instance. Apart from reducing contention this also ensures that memory allocators always create memory segments on the local NUMA node on a NUMA system.

2011-07-18New allocator: Address order first fit (aoff)Sverker Eriksson
