            Bug ID: 20787
           Summary: Common up architecture specific parsing and feature
                    setting
           Product: libraries
           Version: trunk
          Hardware: PC

         Component: Target Description Classes

As discussed in this thread:

http://thread.gmane.org/gmane.comp.compilers.clang.devel/38465

Parsing of architecture specific features (like fpu variants, cpu names, etc)
is multiplied across all tools, including Clang and LLVM.

It'd be good to have a common API, at least for the parsing, with some global
information about each target (like specific enums or bit-fields), or a
callback mechanism to set architecture flags, which is different on each tool
that would use such an API.
