// Add stops where required to prevent read-after-write and write-after-write
// dependencies, for both registers and memory addresses. There are exceptions:
//
// - Compare instructions (cmp*, tbit, tnat, fcmp, frcpa) are OK with
// WAW dependencies so long as they all target p0, or are of parallel
// type (.and*/.or*)

// FIXME: bundling, for now, is left to the assembler.
