llvm for 2D Graphics acceleration


I am very new to this mailing list. I started reading a few documents to get up to speed. I also read about how llvm is used to accelerate the missing hardware support for OpenGL.

I am wondering whether there has been any discussion/efforts in the past regarding 2D acceleration using llvm ? For example, pixman library (which uses MMX/SSE extensions when available) can be used in case of missing hardware support etc. Would llvm be applicable in this case ? Has there been any work in this area ?
