| 31 | * Code generate the whole fragment pipeline. |
| 32 | * |
| 33 | * The fragment pipeline consists of the following stages: |
Brian Paul | 4d2dc9d | 2010-01-20 11:32:48 -0700 | [diff] [blame] | 34 | * - triangle edge in/out testing |
| 35 | * - scissor test |
José Fonseca | 5811ed8 | 2009-08-22 22:26:55 +0100 | [diff] [blame] | 36 | * - stipple (TBI) |
| 37 | * - early depth test |
| 38 | * - fragment shader |
| 39 | * - alpha test |
| 40 | * - depth/stencil test (stencil TBI) |
| 41 | * - blending |
| 42 | * |
| 43 | * This file has only the glue to assembly the fragment pipeline. The actual |
| 44 | * plumbing of converting Gallium state into LLVM IR is done elsewhere, in the |
| 45 | * lp_bld_*.[ch] files, and in a complete generic and reusable way. Here we |
| 46 | * muster the LLVM JIT execution engine to create a function that follows an |
| 47 | * established binary interface and that can be called from C directly. |
| 48 | * |
| 49 | * A big source of complexity here is that we often want to run different |
| 50 | * stages with different precisions and data types and precisions. For example, |
| 51 | * the fragment shader needs typically to be done in floats, but the |
| 52 | * depth/stencil test and blending is better done in the type that most closely |
| 53 | * matches the depth/stencil and color buffer respectively. |
| 54 | * |
| 55 | * Since the width of a SIMD vector register stays the same regardless of the |
| 56 | * element type, different types imply different number of elements, so we must |
| 57 | * code generate more instances of the stages with larger types to be able to |
| 58 | * feed/consume the stages with smaller types. |
