29 * Texture sampling code generation
30 *
31 * This file is nothing more than ugly glue between three largely independent
32 * entities:
33 * - TGSI -> LLVM translation (i.e., lp_build_tgsi_soa)
34 * - texture sampling code generation (i.e., lp_build_sample_soa)
35 * - LLVM pipe driver
36 *
37 * All interesting code is in the functions mentioned above. There is really
38 * nothing to see here.
