llvm-svn: 147304
 2011-12-28 02:24:50 +00:00
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

 - This is made substantially more complicated by the lack of a generalized way
   to check for/invoke cross compilers. For now, we just try and make it work
   for the matched arch, and rely on the host CC being Clang.

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.

   might require the utilities.
