llvm dev - Mar 2013 - [LLVMdev] Hexagon: removing support for Hexagon-v2 and Hexagon-v3

I wanted to give everybody a heads-up on upcoming commits for the 
Hexagon backend. We will be removing support for older versions of the 
Hexagon architecture - specifically Hexagon-v2 and Hexagon-v3. These are 
no longer being used by compiler users. Matthew Curtis has committed the 
first clang patch to remove driver support for these versions. There 
will be follow-up patches on the LLVM side to remove instructions that 
are not used by newer versions of the architecture. After these changes, 
the compiler will support Hexagon-v4 and Hexagon-v5.

Matthew has committed a short blurb in the 3.3 release notes. We'll add 
the reasons behind the removal to that note.

Thanks
-Anshu

There are no customers of yours that use Hexagon-V2 or Hexagon-V3 ??

For newer versions of the compiler, there won't be any users of v2 and v3.
