Kostya Serebryany 809632e28e [asan] interceptors for strcasecmp and strncasecmp. patch by samsonov@google.com
llvm-svn: 147304

Kostya Serebryany 8b981c2564 The code instrumented with ASan may have its own instance of the
mach_override library.
In this case chances are that functions from it will be called from
mach_override_ptr() during ASan initialization.
This may lead to crashes (if those functions are instrumented) or
incorrect behavior (if the implementations differ).

The attached patch renames mach_override_ptr() into
__asan_mach_override_ptr() and makes the rest of the mach_override
internals hidden.
The corresponding AddressSanitizer bug is

Kostya Serebryany 6bb2f1d5b5 Recently the GCD tests started failing because of the invalid size of
FakeStack on the worker threads.
This patch moves the AsanThread initialization into a separate
procedure that's called when AsanThread objects are called for worker
threads.

Daniel Dunbar e2ed5fb636 lib/int_util: My refactoring to allow shared utility code had a fatal flaw when
multiple .a files would end up with duplicate strong definitions. This could
cause link failures in certain scenarios when both definitions got loaded.

Daniel Dunbar e9da222f2f build/SDKs: Sketch a minimal stub SDK for Darwin.
- Motivation is explained in the README, but basically it is convenient to be
   able to build compiler-rt free standing. Since our external dependencies are
   so small, we can achieve this relatively easily by just stubbing out the
   declarations of the external dependencies.
 - This is in no way, shape, or form intended to be complete, it is just the
   minimal stubs necessary to support the stuff we use.
