I saw on the LLVM mailing list some time ago that something like this was desired for Wine (but it was talking about an LLVM backend then). I figured I'd contact you guys to tell you that I found something like this, MojoShader by Ryan Gordon (zlib licensed). http://icculus.org/mojoshader/ http://hg.icculus.org/icculus/mojoshader/ Sorry if someone already suggested this, or if something like this has already been implemented.
