RegionStore, so be explicit about it and generate UnknownVal().
This is a hack to ensure we never produce undefined values for a value
coming from a compound value. (The undefined values can lead to
false positives.)

When enabled, clang generates bounds checks for array and pointers dereferences. Work to follow in LLVM's backend.
OK'ed by Chad; thanks for the review.

disruptive, but it allows RegionStore to better "see" through casts that reinterpret arrays of values
as structs. Fixes <rdar://problem/11405978>.

@throw expression; l2r conversion can introduce new cleanups
in certain cases, like when the expression is an ObjC property
reference of retainable type in ARC.

On Lion, because the rights initially doesn't exist in /etc/authorization, if an admin user logs in and uses lldb within the first 5 minutes, it is possible to do AuthorizationCopyRights on LaunchUsingXPCRightName and get the rights back. As another security measure, we make sure that the LaunchUsingXPCRightName rights actually exists.
Removed Xcode as the user of the XPC service to shrink the security surface area.

We make sure that if the user cancels out of the authentication dialog to add 'com.apple.lldb.LaunchUsingXPC' rights to /etc/authorization, we don't try to do AuthorizationCopyRights.
As well, refactored a bit so that control flow is easier to read for other folks. Added more comments.

don't reason about.
Self is just like a local variable in init methods, so it can be
assigned anything like result of static functions, other methods ... So
to suppress false positives that result in such cases, stop tracking the
checker-specific state after self is being assigned to (unless the
value is't being assigned to is either self or conforms to our rules).
This change does not invalidate any existing regression tests.

When a combine twiddles an extract_vector, care should be take to preserve
the type of the index operand. No luck extracting a reasonable testcase,
unfortunately.

output. Peter Collingbourne also reports that it is showing up in
$(llvm-config --cflags).
Revert this for now since I don't know enough cmake to fix it properly.
This reverts commit 18efed7adc79c1970f307bb5b015d199012ba872.

- Currently this leaves us with less build system support (e.g., installing man pages) for the docs than is desired. I'm working on fixing this, but it may take a while. If someone finds this particularly egregious let me know and I will prioritize it.

For "%hhx", printf expects an unsigned char. This makes Clang
accept a 'char' argument for that also when using -funsigned-char.
This fixes PR12761.
