Remove the nasty LABEL hack with a much less evil one. Now llvm.dbg.func.start implies a stoppoint is set. SelectionDAGISel records a new source line but does not create a ISD::LABEL node for this special stoppoint. Asm printer will magically print this label. This ensures nothing is emitted before.

It is allowed to get the address of an array subscript, even if the array has the register qualifier, if the array is really a pointer.

Fix Sema::ActOnInstanceMessage to correctly do things in terms of canonical 
types, fixing bogus errors like:

NSDistantObject.m:10383:120: error: bad receiver type 'typeof((id<NSMutableCopying>)self)'
    id mess = ({ id __inv__ = ((void *)0); id __mb__ = _NSMessageBuilder((id <NSMutableCopying>)self, &__inv__); (void)[(__typeof__((id <NSMutableCopying>)self))__mb__ mutableCopyWithZone:((void *)0)]; if (!objc_collecting_enabled()) object_dispose(__mb__); __inv__; });

here I fix just one.  The loop that rips through pointers should use
getAsPointerType() not static_cast<PointerType*> to get the pointee.  This
fixes a crash on a large testcase.

fixes crashes where the insertion point was in a macro.  Instead of crashing, we want
to emit a warning.

Add a RewriteTest::ReplaceStmt method to factor the 'checking for
rewrite failed + emitting diagnostic if so' code.

Moved ValueKey/ValueMap declaration to ValueState.h.

Add an extra operand to LABEL nodes which distinguishes between debug, EH, or misc labels. This fixes the EH breakage. However I am not convinced this is *the* solution.

Allow ComplexExpressions in InstrInfo.td files to be slightly more... complex! ComplexExpressions can now have attributes which affect how TableGen interprets
the pattern when generating matchin code. 

The first (and currently, only) attribute causes the immediate parent node of the ComplexPattern operand to be passed into the matching code rather than the node at the root of the entire DAG containing the pattern.

MRegisterInfo::getLocation() is a really bad idea. Its function is to calculate the offset from frame pointer to a stack slot and then storing the delta in a MachineLocation object. The name is bad (it implies a getter), and MRegisterInfo doesn't need to know about MachineLocation.
Replace getLocation() with getFrameIndexOffset() which returns the delta from frame pointer to stack slot. Dwarf writer can then use the information for whatever it wants.

(local) aliasing support.

Modified ExplodedGraph pretty-printer (for GRConstants) to also print out the
pointer value of the state associated with a node.  This way one can easily
see that two states are identical.
