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

Kostya Serebryany 390cf94f88 [asan] asan_allocator2: do not align the requested size to the redzone size (saves a bit more memory) 
llvm-svn: 171111
 2012-12-26 12:20:35 +00:00
Kostya Serebryany 35cc75876a [asan] asan_allocator2: implement adaptive redzones. Now with asan_allocator2 allocations <= 48 bytes have 16 byte redzone, allocations of 48-96 bytes -- have 32 bytes redzone, etc (max redzone is 2048). If ASAN_OPTIONS=redzone=n is set, it changes the minimal redzone size

 2012-12-26 06:30:02 +00:00
Kostya Serebryany 27ad15e165 [asan] asan_allocator2: store the user requested size in just 32 bits (larger sizes use metadata). This allows to put one more 32-bit field into the chunk header

 2012-12-25 09:20:58 +00:00
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

Alexander Potapenko 5e9e51874e [ASan] Make the FileCheck pattern more c++filt-resistant.

llvm-svn: 170543
 2012-12-19 13:46:58 +00:00
Alexey Samsonov ca7fcf2354 Significantly change the way we build ASan unittests in CMake 
build tree. Now just-built Clang is used to:
  1) compile instrumented sources (as before);
  2) compile non-instrumented sources;
  3) compile our own instrumented version of googletest;
  4) link it all together using -fsanitize=address flag
     (instead of trying to copy linker behavior in
      CMake build rules).

This makes ASan unittests pretty much self-consistent
and independent of other LLVM libraries.
