Kostya Serebryany 1cc54f0218 [asan] one more change missed at r171198 
llvm-svn: 171199
 2012-12-28 15:28:19 +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
