llvm-svn: 171968
 2013-01-09 12:03:27 +00:00
Kostya Serebryany cb510e50e2 [asan] implement more strict checking for memset/etc parameters. Instead of checking the first and the last byte, we check the entire shadow region. This costs ~10 slowdown for the instrumented functions. Motivated by a nasty memset-buffer-overflow-by-140-bytes in chrome which was reported as a use-after-free or not at all

Kostya Serebryany ad24c58e16 [sanitizer] increase the maximum size class of the fast allocator. This should save quite a bit of memory in tsan/msan (and later in asan). This also puts more stress on the large allocator. Add a couple of checks
