interface needs implementations to be consistent, so any code which
wants to support different semantics must use a different interface.
It's not currently worthwhile to add a new interface for this new
concept.

Document that AliasAnalysis doesn't support cross-function queries.

This has 2 (slight) advantages:
-Make explicit at getBody()'s callsite that we expect/handle only CompoundStmt and not CXXTryStmt.
-Better tracking of Decl::getBody()'s callsites.

Introduce Decl::hasBody() and FunctionDecl::hasBody() and use them instead of getBody() when we are just checking the existence of a body, to avoid de-serialization of the body from PCH.

Makes de-serialization of the function body even more "lazier".

Fix build for newer versions of GCC that don't include cstring implicitly. Based on a patch by Pawel Wodnicki!

llvm-svn: 107763

Add memcmp() and bcmp() to CStringChecker. These check for valid access to the buffer arguments and have a special-case for when the buffer arguments are known to be the same address, or when the size is zero.

llvm-svn: 107760

Cleanup on CStringChecker and its associated tests. Also check for null arguments...which are allowed if the access length is 0!

builds to "Release".  The default build is unchanged (optimization on,
assertions on), however it is now called Release+Asserts.  The intent
is that future LLVM releases released via llvm.org will be Release builds
in the new sense, i.e. will have assertions disabled (currently they have
assertions enabled, for a more than 20% slowdown).  This will bring them
in line with MacOS releases, which ship with assertions disabled.  It also
means that "Release" now means the same things in make and cmake builds:
cmake already disables assertions for "Release" builds AFAICS.

people seem to write when they want a deterministic trap.
Suggest instead that they use a volatile pointer or 
__builtin_trap.

VisitTypeLoc twice for qualified types, once for the qualified form
and once for the unqualified (though they looked the same by the time
we got to visittypeloc).  Now only visit once, which matches previous
behavior.

emit metadata associating allocas and global values with a Decl*.  This feature
is controlled by an option that (intentionally) cannot be enabled on the command
line.

To use this feature, simply set
  CodeGenOptions.EmitDeclMetadata = true;
and then interpret the completely underspecified metadata. :)
