 /// The CCMP/CCMN/FCCMP/FCCMPE instructions allow the conditional execution of

-/// example "cmp 0 (and (setCA (cmp A)) (setCB (cmp B))))"
+/// example "cmp 0 (and (setCA (cmp A)) (setCB (cmp B)))"
 /// expressed as:
 ///   cmp A
 ///   ccmp B, inv(CB), CA
 ///   check for CB flags
 ///
-/// In general we can create code for arbitrary "... (and (and A B) C)"
-/// sequences. We can also implement some "or" expressions, because "(or A B)"
-/// is equivalent to "not (and (not A) (not B))" and we can implement some
-/// negation operations:
-/// We can negate the results of a single comparison by inverting the flags
-/// used when the predicate fails and inverting the flags tested in the next
-/// instruction; We can also negate the results of the whole previous
-/// conditional compare sequence by inverting the flags tested in the next
-/// instruction. However there is no way to negate the result of a partial
-/// sequence.
+/// This naturally lets us implement chains of AND operations with SETCC
+/// operands. And we can even implement some other situations by transforming
+/// them:
+///   - We can implement (NEG SETCC) i.e. negating a single comparison by
+///     negating the flags used in a CCMP/FCCMP operations.
+///   - We can negate the result of a whole chain of CMP/CCMP/FCCMP operations
+///     by negating the flags we test for afterwards. i.e.
+///     NEG (CMP CCMP CCCMP ...) can be implemented.
+///   - Note that we can only ever negate all previously processed results.
+///     What we can not implement by flipping the flags to test is a negation
+///     of two sub-trees (because the negation affects all sub-trees emitted so
+///     far, so the 2nd sub-tree we emit would also affect the first).
+/// With those tools we can implement some OR operations:
+///   - (OR (SETCC A) (SETCC B)) can be implemented via:
+///     NEG (AND (NEG (SETCC A)) (NEG (SETCC B)))
+///   - After transforming OR to NEG/AND combinations we may be able to use NEG
+///     elimination rules from earlier to implement the whole thing as a
+///     CCMP/FCCMP chain.
 ///
-/// Therefore on encountering an "or" expression we can negate the subtree on
-/// one side and have to be able to push the negate to the leafs of the subtree
-/// on the other side (see also the comments in code). As complete example:
-/// "or (or (setCA (cmp A)) (setCB (cmp B)))
-///     (and (setCC (cmp C)) (setCD (cmp D)))"
-/// is transformed to
-/// "not (and (not (and (setCC (cmp C)) (setCC (cmp D))))
-///           (and (not (setCA (cmp A)) (not (setCB (cmp B))))))"
-/// and implemented as:
+/// As complete example:
+///     or (or (setCA (cmp A)) (setCB (cmp B)))
+///        (and (setCC (cmp C)) (setCD (cmp D)))"

+///     or (and (setCC (cmp C)) setCD (cmp D))
+//         (or (setCA (cmp A)) (setCB (cmp B)))
+/// can be transformed to:
+///     not (and (not (and (setCC (cmp C)) (setCD (cmp D))))
+///              (and (not (setCA (cmp A)) (not (setCB (cmp B))))))"
