From now on we allow the clients to override signal handlers set by ASan, but print a warning in such a case.

Remove the tests for signal() and sigaction(), because they made little sense even without this change.

It is technically reachable on Android, where pthread_exit is not
marked noreturn.

where memcpy() in fact aliases memmove() and thus calling it with
overlapping parameters is not an error.

This should fix http://code.google.com/p/address-sanitizer/issues/detail?id=10

Normally this function should not create copies of constant strings, but it does when the default CFAllocator
is replaced (e.g. under AddressSanitizer)

This test is related to http://code.google.com/p/address-sanitizer/issues/detail?id=10

[asan] workaround for bug http://llvm.org/bugs/show_bug.cgi?id=11763. Do not bark on memcpy(a, a, size).

llvm-svn: 148318

AddressSanitizer: from this patch, ASan allocator returns false for __asan_get_ownership(NULL) and produce error reports for malloc_usable_size(NULL) and __asan_get_allocated_size(NULL)

[asan] remove the test for cfree. 'man cfree' says: 'This function should never be used.' and this function is not found on many OSes we support.

llvm-svn: 147301

llvm-svn: 147297

[asan] added a test to check that a global-buffer-overflow mentioned the module name; revert incorrect change in the test runner
