Switch to allocator2 on Darwin.

llvm-svn: 174603

[ASan] fix the interceptor for siglongjmp. As we're using dylib interposition, we must intercept both siglongjmp and longjmp on Darwin.

llvm-svn: 174510

[asan] print a short one-line report summary after the full report. Currently, works only if symbolization happens in-process.

In case of partial right OOB, ASan was reporting
  X is located 0 bytes to the right of [A, B)
where X was actually inside [A, B).

With this change, ASan will report B as the error address in such case.

[ASan] Split ASan interface header into private and public parts. Add a test that makes sure users can include interface header

llvm-svn: 174058

And make msan_interface.h C-compatible.

llvm-svn: 173928

Use LLVM_BUILD_TYPE instead of CMAKE_BUILD_TYPE in compiler-rt unit tests to match the behavior of llvm unittests

[ASan] fix deallocation hook in allocator2: according to specification, dealloc hook should be called before deallocating memory

llvm-svn: 173778

[ASan] Do allocate memory even for zero-size allocation requests. Explain why we have to do this in comments.

[asan] initialize kHighMemEnd at startup (instead of at compile time) to simplify further changes for various address space layouts. Fix asan_allocator2 for PowerPC (tested on 44-bit address space)

[ASan] Remove the declarations of pthread_workqueue_t and pthread_workitem_handle_t, which are used no more.

We already have Darwin-specific version of this test.

llvm-svn: 173136

This CL drastically simplifies the way we're hooking the memory allocation routines in ASan on Mac by using dylib interposition to replace the main malloc_zone_* functions. This allows us to avoid replacing the default CFAllocator and drop the CF dependency at all.

Committing this patch will result in the static runtime being broken. A follow-up CL will switch ASan to use the dynamic runtime library.

ASan: disable flexible mapping and offset on Android. It doesn't work for dynamic ASan runtime there

[asan] split asan_test.cc to speedup parallel build (most important if building with a debug clang, which takes a couple of minutes on this large file with templates). More splits to follow
