Change err_pp_file_not_found back to an Error; when it's a Warning, we suppress it in system headers.  And it is not a good idea to suppress it in system headers.  (This was originally changed in r134996 to implement -MG.)

Fixes <rdar://10041960>.  And also brings down the number of warnings without a flag by one :)

collision between C99 hexfloats and C++0x user-defined literals by
giving C99 hexfloats precedence. Also, warning about user-defined
literals that conflict with hexfloats and those that have names that
are reserved by the implementation. Fixes <rdar://problem/9940194>.

This makes the code duplication of implicit special member handling even worse,
but the cleanup will have to come later. For now, this works.
Follow-up with tests for explicit defaulting and enabling the __has_feature
flag to come.

Empty lookups can occur in the DeclContext map when we are chaining PCHs, where
the empty lookup indicates that we already looked in ExternalASTSource.

Doing this happens to disrupt the pattern that ARC was looking for
for move optimizations, so we need to fix that simultaneously.

- wrong alignment for double (it was 4, but 8 is desired),
- added checks for _REENTRANT define,
- fixed the issue that defines were not tested (because the check for inside #ifdef).

Thread safety: added basic handling for pt_guarded_by/var and guarded_by/var annotations. We identify situations where we are accessing (reading or writing) guarded variables, and report an error if the appropriate locks are not held.

qualification of a type doesn't affect whether a conversion is a narrowing
conversion.
This doesn't work in template cases because SubstTemplateTypeParmType gets in
the way.

This matches gcc's logic. Second half of PR10661.

[analyzer] Introduce a new callback for checkers, printState, to be used for debug-printing the contents of a ProgramState.

Unlike the other callbacks, this one is a simple virtual method, since it is only to be used for debugging.

This new callback replaces the old ProgramState::Printer interface, and allows us to move the printing of refcount bindings from CFRefCount to RetainReleaseChecker.

llvm-svn: 138728

[analyzer] Remove the ProgramState argument from ExprEngine::evalBind; we were ignoring it anyway. No functionality change.

This is a common path for function and C++ method calls, Objective-C messages and property accesses, and C++ construct-exprs.

As support, add message receiver accessors to ObjCMessage and CallOrObjCMessage.

llvm-svn: 138718

[analyzer] Change the check::RegionChanges callback to include the regions explicitly requested for invalidation.

Also, allow CallOrObjCMessage to wrap a CXXConstructExpr as well.

Finally, this allows us to remove the clunky whitelisting system from CFRefCount/RetainReleaseChecker. Slight regression due to CXXNewExprs not yet being handled in post-statement callbacks (PR forthcoming).

standards justification for this, but it matches what other compilers do
and therefore preserves compatibility with certain template metaprogramming
idioms.

__import__ within the preprocessor, since the prior one foolishly
assumed that Preprocessor::Lex() was re-entrant. We now handle
__import__ at the top level (only), after macro expansion. This should
fix the buildbot failures.
