This code was meant to be used as the IR in Mesa. So it was GLSL->tgsi->LLVM IR. There's a very old branch that has a GLSL compiler that produces LLVM from GLSL but it was never finished/integrated. It's here: http://cgit.freedesktop.org/~zack/mesa.git.old/?h=llvm > What is the right place to generate LLVM IR? A new pass that operates on > mesa's IR? From _slang_emit_code? If you're using Gallium then that code already exists in gallivm (to generate llvm ir from tgsi). If you want to generate LLVM ir directly from GLSL and pass that to the driver then we'd need to figure out the type of LLVM representation that we'd want. Realistically initially we'd also want LLVM IR -> tgsi backedn simply because the drivers we have right now use TGSI and it'd be quicker to initially write that rather than rewrite the drivers. z ------------------------------------------------------------------------------ Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.
