- * Possibly returns an instruction that set up @param reg.
- *
- * Sometimes we want to take the result of some expression/variable
- * dereference tree and rewrite the instruction generating the result
- * of the tree.  When processing the tree, we know that the
- * instructions generated are all writing temporaries that are dead
- * outside of this tree.  So, if we have some instructions that write
- * a temporary, we're free to point that temp write somewhere else.
- *
- * Note that this doesn't guarantee that the instruction generated
- * only reg -- it might be the size=4 destination of a texture instruction.
