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