+// The SPIR-V spec requires code blocks to appear in an order satisfying the
+// dominator-tree direction (ie, dominator before the dominated).  This is,
+// actually, easy to achieve: any pre-order CFG traversal algorithm will do it.
+// Because such algorithms visit a block only after traversing some path to it
+// from the root, they necessarily visit the block's idom first.
+//
+// But not every graph-traversal algorithm outputs blocks in an order that
+// appears logical to human readers.  The problem is that unrelated branches may
+// be interspersed with each other, and merge blocks may come before some of the
+// branches being merged.
+//
+// A good, human-readable order of blocks may be achieved by performing
+// depth-first search but delaying merge nodes until after all their branches
+// have been visited.  This is implemented below by the inReadableOrder()
+// function.
