Log Message:
LLVM 3.0 includes several major changes and big features:
* llvm-gcc is no longer supported, and not included in the release. We recommend
  switching to Clang or DragonEgg.
* The linear scan register allocator has been replaced with a new "greedy"
  register allocator, enabling live range splitting and many other optimizations  that lead to better code quality. Please see its blog post or its talk at the
  Developer Meeting for more information.
* LLVM IR now includes full support for atomics memory operations intended to
  support the C++'11 and C'1x memory models. This includes atomic load and
  store, compare and exchange, and read/modify/write instructions as well as
  a full set of memory ordering constraints. Please see the Atomics Guide for
  more information.
* The LLVM IR exception handling representation has been redesigned and
  reimplemented, making it more elegant, fixing a huge number of bugs, and
  enabling inlining and other optimizations. Please see its blog post and the
  Exception Handling documentation for more information.
* The LLVM IR Type system has been redesigned and reimplemented, making it
  faster and solving some long-standing problems. Please see its blog post for
  more information.
* The MIPS backend has made major leaps in this release, going from an
  experimental target to being virtually production quality and supporting
  a wide variety of MIPS subtargets. See the MIPS section below for more
  information.
* The optimizer and code generator now supports gprof and gcov-style coverage
  and profiling information, and includes a new llvm-cov tool (but also works
  with gcov). Clang exposes coverage and profiling through GCC-compatible
  command line options.
