Richard Smith cf56ebd52a ubsan: When diagnosing something wrong somewhere in memory, emit a note 
pointing at the bad location and a snippet of nearby memory values. This is
strictly best-effort; reading these bytes to display the note could lead to a
seg fault, and that's explicitly OK.

Richard Smith 54fc2370f9 Don't escape %s in printf usage message; it's not written by printf.

Richard Smith 52987120f9 ubsan: if the frontend didn't provide us with a source location, try to work 
one out from the return address. Currently, we can only resolve this address to
a file and line number if we have an external symbolizer.

Richard Smith 37a913ae8f Rein ubsan's vptr sanitizer back a bit. Per core issue 453, binding a reference 
to an object outside its lifetime does not have undefined behavior.

llvm-svn: 170109
 2012-12-13 07:12:20 +00:00
Richard Smith 32952215b6 ubsan: Add -fsanitize=bool and -fsanitize=enum, which check for loads of 
bit-patterns which are not valid values for enumerated or boolean types.
These checks are the ubsan analogue of !range metadata.

Kostya Serebryany 07bb3925b0 [sanitizer] replace size_t with SIZE_T in interceptors (same for ssize_t, off_t and off64_t). This is done to avoid confusion and to make the code work with compilers that define size_t w/o any includes (MSVC)

 2012-12-13 05:27:08 +00:00
Kostya Serebryany 2ce42e0aef [sanitizer] change the way SizeClassAllocator64 allocated memory from the system: instead of one huge mmap(NORESERVE) it does one huge mprotect and then does small on-demand mmaps. This allows us to call OnMap callbacks which are required to poison newly allocated memory in asan
