     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.
-  
+  per-instruction debug info metadata is much faster and uses less space (new DebugLoc class).
+  -ffunction-sections and -fdata-sections are supported on ELF targets.
+  Now iterate function passes when a cgsccpassmanager detects a devirtualization
+  -momit-leaf-frame-pointer now supported.
+  New -regalloc=fast,  =local got removed
+  New -regalloc=default option that chooses a register allocator based on the -O optimization level.
+  New "trap values" concept: http://llvm.org/docs/LangRef.html#trapvalues
+  Improved trip count analysis for <= and >= loops, and uses sign overflow info.
+  REMOVED: SCCVN pass.
+  X86 backend attempts to promote 16-bit integer operations to 32-bits to avoid
+     0x66 prefixes, which are slow on some microarchitectures and bloat the code
+     on others.
+  X87 fp stackifier is global!
+  LTO debug info support?
+  NEON: Better performance for QQQQ (4-consecutive Q register) instructions.  New reg sequence abstraction?
+  New support for X86 "thiscall" calling convention (x86_thiscallcc in IR).
+  ARM: Better scheduling (list-hybrid, hybrid?)
+  New SubRegIndex tblgen class for targets -> jakob
+  ARM: Tail call support.
+  AVX support in the MC assembler.  Full compiler support not done yet.
+  Atomics now get legalized when not natively supported (jim g)
+  ARM: General performance work and tuning.
