+  llvm.dbg.value: variable debug info for optimized code
+  MC Assembler backend is now real, does relaxation and is bitwise identical
+    with darwin assembler in huge majority of all cases.
+  new GHC calling convention
+  New half float intrinsics LangRef.html#int_fp16
+  Rewrote tblgen's type inference for backends to be more consistent and
+     diagnose more target bugs.  This also allows limited support for writing
+     patterns for instructions that return multiple results, e.g. a virtual
+     register and a flag result.  Stuff that used 'parallel' before should use
+     this.
+  New ARM/Thumb disassembler support in MC.
+  New SSEDomainFix pass: 
+    On Nehalem and newer CPUs there is a 2 cycle latency penalty on using a
+    register in a different domain than where it was defined. Some instructions
+    have equvivalents for different domains, like por/orps/orpd.  The
+    SSEDomainFix pass tries to minimize the number of domain crossings by
+    changing between equvivalent opcodes where possible.
+  Support for the Intel AES instructions in the assembler.
+  memcpy, memmove, and memset now take address space qualified pointers + volatile.
