[Xen-devel] [PATCH 0 of 2] [RFC] Allow link-time optimization of Xen

[Tim Deegan <Tim.Deegan@xxxxxxxxxx>]

This patch series applies on top of the clang/llvm one I just posted. 
It rearranges the Xen makefiles so that Xen can be built using 
bitcode intermediate files and link-time optimization.  Since 
gold can't link binary and bitcode files together to produce a 
bitcode file, we need to gather binary objects and bitcode objects
separately until the final link. 

The first patch does that and is a candidate for checking in, although
maybe not immediately. The second is just a hack to work around a bug
in the LLVM linker,  and is just here for anyone who wants to try it out.
