-/** NIR Control Flow Modification
- *
- * This file contains various API's that make modifying control flow in NIR,
- * while maintaining the invariants checked by the validator, much easier.
- * There are two parts to this:
- *
- * 1. Inserting control flow (if's and loops) in various places, for creating
- *    IR either from scratch or as part of some lowering pass.
- * 2. Taking existing pieces of the IR and either moving them around or
- *    deleting them.

-/** Control flow motion.
- *
- * These functions let you take a part of a control flow list (basically
- * equivalent to a series of statement in GLSL) and "extract" it from the IR,
- * so that it's a free-floating piece of IR that can be either re-inserted
- * somewhere else or deleted entirely. A few notes on using it:
- *
- * 1. Phi nodes are considered attached to the piece of control flow that
- *    their sources come from. There are three places where phi nodes can
- *    occur, which are the three places where a block can have multiple
- *    predecessors:
- *
- *    1) After an if statement, if neither branch ends in a jump.
- *    2) After a loop, if there are multiple break's.
- *    3) At the beginning of a loop.
- *
- *    For #1, the phi node is considered to be part of the if, and for #2 and
- *    #3 the phi node is considered to be part of the loop. This allows us to
- *    keep phi's intact, but it means that phi nodes cannot be separated from
- *    the control flow they come from. For example, extracting an if without
- *    extracting all the phi nodes after it is not allowed, and neither is
- *    extracting only some of the phi nodes at the beginning of a block. It
- *    also means that extracting from the beginning of a basic block actually
- *    means extracting from the first non-phi instruction, since there's no
- *    situation where extracting phi nodes without extracting what comes
- *    before them makes any sense.
- *
- * 2. Phi node sources are guaranteed to remain valid, meaning that they still
- *    correspond one-to-one with the predecessors of the basic block they're
- *    part of. In addition, the original sources will be preserved unless they
- *    correspond to a break or continue that was deleted. However, no attempt
- *    is made to ensure that SSA form is maintained. In particular, it is
- *    *not* guaranteed that definitions of SSA values will dominate all their
- *    uses after all is said and done. Either the caller must ensure that this
- *    is the case, or it must insert extra phi nodes to restore SSA.
- *
- * 3. It is invalid to move a piece of IR with a break/continue outside of the
- *    loop it references. Doing this will result in invalid
- *    successors/predecessors and phi node sources.
- *
- * 4. It is invalid to move a piece of IR from one function implementation to
- *    another.
- *
- * 5. Extracting a control flow list will leave lots of dangling references to
- *    and from other pieces of the IR. It also leaves things in a not 100%
- *    consistent state. This means that some things (e.g. inserting
- *    instructions) might not work reliably on the extracted control flow. It
- *    also means that extracting control flow without re-inserting it or
- *    deleting it is a Bad Thing (tm).
