/**

* @file
|
|
* Code generate the whole fragment pipeline.
|
|
*
|
|
* The fragment pipeline consists of the following stages:
|
|
* - early depth test
|
|
* - fragment shader
|
|
* - alpha test
|
|
* - depth/stencil test
|
|
* - blending
|
|
*
|
|
* This file has only the glue to assemble the fragment pipeline. The actual
|
|
* plumbing of converting Gallium state into LLVM IR is done elsewhere, in the
|
|
* lp_bld_*.[ch] files, and in a complete generic and reusable way. Here we
|
|
* muster the LLVM JIT execution engine to create a function that follows an
|
|
* established binary interface and that can be called from C directly.
|
|
*
|
|
* A big source of complexity here is that we often want to run different
|
|
* stages with different precisions and data types and precisions. For example,
|
|
* the fragment shader needs typically to be done in floats, but the
|
|
* depth/stencil test and blending is better done in the type that most closely
|
|
* matches the depth/stencil and color buffer respectively.
|
|
*
|
|
* Since the width of a SIMD vector register stays the same regardless of the
|
|
* element type, different types imply different number of elements, so we must
|
|
* code generate more instances of the stages with larger types to be able to
|
|
* feed/consume the stages with smaller types.
