Cameron Zwarich wrote: > What benefit do you get from having a backend here rather than an interpreter for LLVM IR? The same thing as an interpreter, just a native build (no need for an interpreter program, better speed, etc). This would be beneficial anywhere that "build once, deploy anywhere" functionality is desired, without resorting to using a higher-level language like C# or

All were x86 and the program was text-based, but I'd say my LLVM Wrapper would be worth some effort in the future if I could just get some help. Currently it just wraps StdIO.h with its own functions Naturally that would work perfectly fine on a similar

A backend that's self-sufficient and covers the entire Unixoid world. That cuts down on the number of binaries that one needs to provide for autoinstallers and such. Generated Perl could be used to bootstrap an LLVM IR interpreter, for example.

Although this would indeed be nice, it is not done by similar platforms in practice. I have investigated [very] briefly into whether the

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
