Alexander Potapenko 47a03a2ebe [ASan] Fix another FileCheck pattern to be c++filt-proof. 
llvm-svn: 170878
 2012-12-21 10:48:30 +00:00
Alexey Samsonov 53a965e125 [Sanitizer] Don't implicitly add object files to the list of dependencies when building compiler_rt unittests. Fix sanitizer_common and asan build rules accordingly. This also fixes check-sanitizer command on Ninja.

Kostya Serebryany c0d8ca5537 [asan] asan_allocator2: implement memalign 
llvm-svn: 170697
 2012-12-20 14:35:06 +00:00
Alexander Potapenko 5e9e51874e [ASan] Make the FileCheck pattern more c++filt-resistant. 
This test didn't pass for me locally because of "T0's stack" being converted to "T0'short stack" by c++filt.
Strange enough this doesn't show up on our bots.

Alexey Samsonov b29d37bea5 [ASan] make sure Android unittests depend on ASan runtime 
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.
