 2012-12-20 13:24:21 +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.

Dmitry Vyukov 9c7bcfea6f tsan: remove TSAN_OPTIONS from the script 
The runtime skips atexit sleep if there are no threads now,
so it must be fast w/o it.

Richard Smith cf56ebd52a ubsan: When diagnosing something wrong somewhere in memory, emit a note 
pointing at the bad location and a snippet of nearby memory values. This is
strictly best-effort; reading these bytes to display the note could lead to a
seg fault, and that's explicitly OK.

Richard Smith 52987120f9 ubsan: if the frontend didn't provide us with a source location, try to work 
one out from the return address. Currently, we can only resolve this address to
