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.
Allows to specify own TSAN_OPTIONS for the tests.

llvm-svn: 170417
 2012-12-18 06:57:34 +00:00
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
a file and line number if we have an external symbolizer.

 2012-12-13 05:27:08 +00:00
Kostya Serebryany 2ce42e0aef [sanitizer] change the way SizeClassAllocator64 allocated memory from the system: instead of one huge mmap(NORESERVE) it does one huge mprotect and then does small on-demand mmaps.

Alexander Potapenko 7b03290c43 Implement internal_memmove. 
Use internal_memmove() and internal_memcpy() in the memcpy() and memmove() wrappers
when building the dynamic runtime (OS X only), to work around a bug in resolver functions wrapping.

Chandler Carruth eea8a48218 Fix the bootstrap of CompilerRT with host compilers that don't support 
emulating 128-bit arithmetic on 32-bit x86 targets. This should get the
bootstrap back for GCC 4.6 at least.

Suggestions on better ways to do the detection here are welcome...
