Dmitry Vyukov ed6d54368c tsan: comment out debug output in test 
llvm-svn: 170186
 2012-12-14 10:12:14 +00:00
Kostya Serebryany 2ce42e0aef [sanitizer] change the way SizeClassAllocator64 allocated memory from the system: instead of one huge mmap(NORESERVE) it does one huge mprotect and then does small on-demand mmaps. This allows us to call OnMap callbacks which are required to poison newly allocated memory in asan

Dmitry Vyukov 7e6347402d tsan: fix new memory allocator 
Deallocate: drain blocks to central cache if cached too much (instead of never drain).
Allocate: batch allocate fixed amount of blocks (instead of all blocks).
This significantly reduces memory consumption of large heavy-multithreaded programs.
