Subject: asan/tsan: reduce per-thread memory allocator caches
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=31056968fc2863f5a66e0a537b90435714af4861;p=platform%2Fupstream%2Fllvm.git

asan/tsan: reduce per-thread memory allocator caches
256 blocks (which is 512 in reallity) seems to be too big cache,
reducing the size reduces memory consumption but does not degrade performance.
