  New llvm.fma intrinsic.
  
  Euro dev meeting and main one too.
- New atomics instructions, "#i_fence" instruction, cmpxchg, atomicrmw too.  What target support? Also 'atomic load/store'.  See Atomics.html
+ New atomics instructions, "#i_fence" instruction, cmpxchg, atomicrmw too.  What target support (X86/ARM)? Also 'atomic load/store'.  See Atomics.html
  X86: inline assembler supports .code32 and .code64.
  Exception handling rewrite: new landingpad and resume instruction.  Unwind gone.
  LowerSetJmp pass removed, unused.
  llvm-objdump (d0k) and object file parsing stuff (mspencer)
  Old arm disassembler replaced with a new one based on autogenerated encoding information from ARM .td files.
+ Frontend tests removed from llvm/test/Frontend* (was this completed for 3.0?)
+ Segmented stack support (X86 only?) Rafael and Sanjoy Das: docs/SegmentedStacks.html should be in CodeGen.html status table?
+ X86 backend support for NaCl (David Meyer / Nick L)
+ Codegen now supports vector "select" operations on vector comparisons, turning
+   them into various optimized code sequences (e.g. using the SSE4/AVX "blend"
+   instructions).
