 LLVMPIPE -- a fork of softpipe that employs LLVM for code generation.
 
 
-Status
-======
-
-Done so far is:
-
- - the whole fragment pipeline is code generated in a single function
- 
-   - input interpolation
-   
-   - depth testing
- 
-   - texture sampling
-     - 1D/2D/3D/cube maps supported
-     - all texture wrap modes supported
-     - all texture filtering modes supported
-     - perhaps not all texture formats yet supported
-   
-   - fragment shader TGSI translation
-     - same level of support as the TGSI SSE2 exec machine, with the exception
-       we don't fallback to TGSI interpretation when an unsupported opcode is
-       found, but just ignore it
-     - done in SoA layout
-     - input interpolation also code generated
- 
-   - alpha testing
- 
-   - blend (including logic ops)
-     - both in SoA and AoS layouts, but only the former used for now
- 
- - code is generic
-   - intermediates can be vectors of floats, ubytes, fixed point, etc, and of
-     any width and length
-   - not all operations are implemented for these types yet though
-
-Most mesa/progs/demos/* work. 
-
-To do (probably by this order):
-
- - code generate stipple and stencil testing
-
- - translate TGSI control flow instructions, and all other remaining opcodes
- 
- - integrate with the draw module for VS code generation
-
- - code generate the triangle setup and rasterization
-

 This will ensure that frame pointers are used both in C and JIT functions, and
