LLVM 2.7 includes several major new capabilities:
-- New MicroBlaze backend. http://en.wikipedia.org/wiki/MicroBlaze
+- This release includes initial support for the MicroBlaze target.
+ MicroBlaze is a soft processor core designed for Xilinx FPGAs.
-- Extensible metadata solid.
+- LLVM 2.7 includes a new LLVM IR "extensible metadata" feature. This feature
+ supports many different use cases, including allowing front-end authors to
+ encode source level information into LLVM IR, which is consumed by later
+ language-specific passes. This is a great way to do high-level optimizations
+ like devirtualization, type-based alias analysis, etc. See the
+ Extensible Metadata Blog Post for more information.
+
+- LLVM 2.7 encodes debug information
+in a completely new way, built on extensible metadata. The new implementation
+is much more memory efficient and paves the way for improvements to optimized
+code debugging experience.
-- Debug info improvements: using metadata instead of llvm.dbg global variables.
-This brings several enhancements including improved compile times.
+- LLVM 2.7 now directly supports taking the address of a label and doing an
+ indirect branch through a pointer. This is particularly useful for
+ interpreter loops, and is used to implement the GCC "address of label"
+ extension. For more information, see the
+Address of Label and Indirect Branches in LLVM IR Blog Post.

+- LLVM 2.7 is the first release to start supporting APIs for assembling and
+ disassembling target machine code. These APIs are useful for a variety of
+ low level clients, and are surfaced in the new "enhanced disassembly" API.
+ For more information see the The X86
+ Disassembler Blog Post for more information.
-- New instruction selector.
+- LLVM 2.7 includes major parts of the work required by the new MC Project,
+ which aims to rework our handling of low-level machine code. A few targets
+ have been refactored to support it, and work is underway to support a native
+ assembler in LLVM. This work is not complete in LLVM 2.7, but you has made
+ substantially more progress on LLVM mainline. You can read more about this
+ in the
+ Intro to the LLVM MC Project Blog Post.

- LLVM IR now supports a 16-bit "half float" data type through two new intrinsics and APFloat support.
+- LLVM IR supports two new function
+ attributes: inlinehint and alignstack(n). The former is a hint to the
+ optimizer that a function was declared 'inline' and thus it might be useful
+ to increase the chances the the inliner actually inline it. The later
+ indicates to the code generator that the function diverges from the platform
+ ABI on stack alignment.
+- The new llvm.objectsize intrinsic
+ allows the optimizer to infer the sizes of memory objects in some cases.
+ This intrinsic is used to implement the GCC __builtin_object_size
+ extension.
+- LLVM 2.7 has pre-alpha support for unions in LLVM IR.
+ Unfortuantely, this support is not really usable in 2.7, so if you're
+ interested in pushing it forward, please help contribute to LLVM mainline.
