#![allow(clippy::unwrap_used)]
//! The listings of programs Microsoft's `D3DAssemble` assembled, against `D3DDisassemble`'s, byte for byte: every
//! Shader Model 1 to 3 operation alone (the `slots_` programs, which pin each one's instruction slots in each version),
//! the one-feature programs of iridia-d3d9-ir's executor tests, and the cases Microsoft's listing writes oddly
//! (`probe_`: predication, `breakp`). `tests/assembled/assemble.py` makes the `.bin`, `.asm.ms` (no flags) and
//! `.flag04.ms` (instruction numbering) files from the `.asm` sources.
