Alexander Potapenko 1d021bff28 [libsanitizer] Run the callback on a separate stack in StopTheWorld. 
Currently the callback runs on the caller's stack. If this stack
contains values that have gone out of scope, and we are not super careful, those
values can propagate into global variables (the libc sigaction() in particular
has a side effect that can lead to this). This has caused false negatives in
leak checking code.

Changes: map a separate stack space for the tracer thread. Also, move some
globals into local scope (they had no business being global anyway).

Alexey Samsonov e624795558 [ASan] More careful reports for globals that are ASCII strings 
llvm-svn: 178458
 2013-04-01 08:57:38 +00:00
Michael Gottesman 4ddc2156d6 Change the cmake variable COMPILER_RT_CAN_EXECUTE_TESTS to be an option so that it can overwritten. 
The reason why this simple change is needed is that I am trying to set up a
quick cmake/ninja based buildbot and apple-clang does not support using the
sanitizers currently.

The default behavior follows exactly what was there before implying that no ones
builds should be affected at all.

Alexey Samsonov a88c60b085 [ASan] Speed-up initialization-order checking: create and use fast versions of PoisonShadow functions, store copies of __asan_global descriptors in a vector instead of list of pointers. This gives 3x speedup on both benchmarks and real binaries with lots of globals.
