Major new features:

Browse Source 
* AddressSanitizer, a fast memory error detector.
      * MachineInstr Bundles, Support to model instruction 
        bundling / packing.
      * ARM Integrated Assembler, A full featured assembler 
        and direct-to-object support for ARM.
      * Basic Block Placement Probability driven basic block placement.
  
  LLVM IR and Core Improvements
     
      * IR support for half float
      * IR support for vectors of pointers, including vector GEPs.
      * Module flags have been introduced.
      * Loads can now have range metadata attached to them to 
        describe the possible values being loaded. 
      * Inline cost heuristics have been completely overhauled 
        and now closely model constant propagation through call sites, 
        disregard trivially dead code costs, and 
        can model C++ STL iterator patterns.
   
  Optimizer Improvements
      * The loop unroll pass now is able to unroll loops with 
        run-time trip counts. This feature is turned off by default, 
        and is enabled with the -unroll-runtime flag.
      * A new basic-block autovectorization pass is available. 
        Pass -vectorize to run this pass along with some associated 
        post-vectorization cleanup passes. 
   X86-32 and X86-64 Target Improvements
      * Bug fixes and improved support for AVX1
      * Support for AVX2 (still incomplete at this point)

- Update to svn revision 154914 from 3.1 branch
Major new features:
* AddressSanitizer, a fast memory error detector.
* MachineInstr Bundles, Support to model instruction
bundling / packing.
* ARM Integrated Assembler, A full featured assembler
and direct-to-object support for ARM.
* Basic Block Placement Probability driven basic block placement.
LLVM IR and Core Improvements
* IR support for half float
* IR support for vectors of pointers, including vector GEPs.
* Module flags have been introduced.
* Loads can now have range metadata attached to them to
describe the possible values being loaded.
* Inline cost heuristics have been completely overhauled
and now closely model constant propagation through call sites,
disregard trivially dead code costs, and
can model C++ STL iterator patterns.
Optimizer Improvements
* The loop unroll pass now is able to unroll loops with
run-time trip counts. This feature is turned off by default,
and is enabled with the -unroll-runtime flag.
* A new basic-block autovectorization pass is available.
Pass -vectorize to run this pass along with some associated
post-vectorization cleanup passes.
X86-32 and X86-64 Target Improvements
* Bug fixes and improved support for AVX1
* Support for AVX2 (still incomplete at this point)
ARM Target Improvements
* The constant island pass now supports basic block and
constant pool entry alignments greater than 4 bytes.
Clang Changes
* New: -Wdangling-else, -Wstrncat-size
* Improved: -Wformat, -Wempty-body, -Wliteral-conversion
* Clang 3.1 adds support for anonymous structs and anonymous unions,
added in the latest ISO C standard. Use -std=c11 or -std=gnu11
to enable support for the new language standard.
The new C11 features are backwards-compatible and are available
as an extension in all language modes.
* All warning and language selection flags which previously accepted
c1x have been updated to accept c11. The old c1x forms have been removed.
* Generalized constant expressions
* Lambda expressions
* Generalized initializers
* Unrestricted unions
* User-defined literals
* Forward-declared enumerations
* Atomics (both libc++'s and libstdc++4.7's <atomic> are supported)
