Use CrashRecoveryContextCleanup objects to recover an ASTUnit if we crash in ASTUnit::LoadFromCommandLine() and ASTUnit::LoadFromCompilerInvocation().

Use CrashRecoveryContextCleanup objects to release resources associated with Sema during a crash while parsing.

Fix PR9488: 'auto' type substitution can fail (for instance, if it creates a reference-to-void type). Don't crash if it does.
Also fix an issue where type source information for the resulting type was being lost.

llvm-svn: 127811

Remove code that was intentionally generating bad code on the GNU runtime for no reason (failing to emit .cxx_constructor / .cxx_destructor methods).

llvm-svn: 127806

Don't construct two CFGs just to run -Wuninitialized.  While this causes new warnings to be flagged under -Wconditional-uninitialized, this is something we
can improve over time.

Teach VariadicMethodTypeChecker that CF references are valid arguments to variadic Objective-C methods.

llvm-svn: 127797

Tweak RegionStore's handling of lazy compound values to use the 'Default' versus 'Direct' binding key, thus allowing specific elements of an array/struct to be overwritten without
invalidating the entire binding.  Fixes PR 9455.

dependent scope and produce an error (rather than crashing). Fixes PR8979.

llvm-svn: 127749

Having FileManager::getFile always open the file, brought much consternation and leaking of file descriptors.

Add 'openFile' bool to FileManager::getFile to specify whether we want to have the file opened or not, have it
false by default, and enable it only in HeaderSearch.cpp where the open+fstat optimization matters.

Fixes rdar://9139899.

overload, so that we actually do the resolution for full expressions
and emit more consistent, useful diagnostics. Also fixes an IRGen
crasher, where Sema wouldn't diagnose a resolvable bound member
function template-id used in a full-expression (<rdar://problem/9108698>).

clients to observe the exact path through which an #included file was
located. This is very useful when trying to record and replay inclusion
operations without it beind influenced by the aggressive caching done
inside the FileManager to avoid redundant system calls and filesystem
operations.

The work to compute and return this is only done in the presence of
callbacks, so it should have no effect on normal compilation.

operands to a binary expression; it doesn't make sense in all
contexts. The right answer would be to see if the user forgot at ().

ActOnFinishFunctionBody/ActOnBlockStmtExpr. This way, we ensure that
we diagnose undefined labels before the jump-scope checker gets run,
since the jump-scope checker requires (as its invariant) that all of
the GotoStmts be wired up correctly.

Fixes PR9495.

llvm-svn: 127738

forward-looking "goto" statement, make sure to insert it *after* the
last declaration in the identifier resolver's declaration chain that
is either outside of the function/block/method's scope or that is
declared in that function/block/method's specific scope. Previously,
we could end up inserting the label ahead of declarations in inner
scopes, confusing C++ name lookup.

Fixes PR9491/<rdar://problem/9140426> and <rdar://problem/9135994>.

Note that the crash-on-invalid PR9495 is *not* fixed. That's a
separate issue.

VariadicMethodTypeChecker: don't warn for null pointer constants passed to variadic Objective-C methods.

llvm-svn: 127719

Remove warning for null characters in CFString literals.  Clang handles them just fine, and GCC 4.2 doesn't warn here either.

We added this warning back in 2007 when we were comparing against GCC 4.0.
