* 2) A subset of item 1) is if all possible code points outside the bitmap
* match. This is a common occurrence when the class is complemented,
* like /[^ij]/. Therefore a bit is reserved to indicate this,
- * rather than having an expensive swash created,
+ * rather than having a more expensive inversion list created,
* ANYOF_MATCHES_ALL_ABOVE_BITMAP.
* 3) Under /d rules, it can happen that code points that are in the upper
* latin1 range (\x80-\xFF or their equivalents on EBCDIC platforms) match
* handled. But it can be a shared flag: see 5) below.
* 4) Also under /d rules, something like /[\Wfoo]/ will match everything in
* the \x80-\xFF range, unless the string being matched against is UTF-8.
- * A swash could be created for this case, but this is relatively common,
- * and it turns out that it's all or nothing: if any one of these code
- * points matches, they all do. Hence a single bit suffices. We use a
- * shared flag that doesn't take up space by itself:
- * ANYOF_SHARED_d_MATCHES_ALL_NON_UTF8_NON_ASCII_non_d_WARN_SUPER.

* will match, so we have to assume it could match anything, including
* shared with another, so it doesn't occupy extra space.
*
* At the moment, there is one spare bit, but this could be increased by
- * various tricks.
+ * various tricks:
*

* best choice would be to make ANYOF_MATCHES_ALL_ABOVE_BITMAP not a flag, but
* something like
*
* handler function, as the macro REGINCLASS in regexec.c does now for other
* cases.
*
- * Another possibility is to instead (or additionally) rename the ANYOF_POSIXL
- * flag to be ANYOFL_LARGE, to mean that the ANYOF node has an extra 32 bits
- * beyond what a regular one does. That's what it effectively means now, with
- * the extra space all for the POSIX class flags. But those classes actually
- * only occupy 30 bits, so the ANYOFL_FOLD and
- * ANYOFL_SHARED_UTF8_LOCALE_fold_HAS_MATCHES_nonfold_REQD flags could be moved
- * to that extra space. The 30 bits in the extra word would indicate if a
- * posix class should be looked up or not. The downside of this is that ANYOFL
- * nodes with folding would always have to have the extra space allocated, even
- * if they didn't use the 30 posix bits. There isn't an SSC problem as all
- * SSCs are this large anyway.
+ * Another possibility is based on the fact that ANYOF_MATCHES_POSIXL is
+ * redundant with the node type ANYOFPOSIXL. That flag could be removed, but
+ * at the expense of extra code in regexec.c. The flag has been retained
+ * because it allows us to see if we need to call reginsert, or just use the
+ * bitmap in one test.
*
- * One could completely remove ANYOFL_LARGE and make all ANYOFL nodes large.
- * REGINCLASS would have to be modified so that if the node type were this, it
- * would call reginclass(), as the flag bit that indicates to do this now would
- * be gone.
+ * If this is done, an extension would be to make all ANYOFL nodes contain the
+ * extra 32 bits that ANYOFPOSIXL ones do. The posix flags only occupy 30
+ * bits, so the ANYOFL_SHARED_UTF8_LOCALE_fold_HAS_MATCHES_nonfold_REQD flags
+ * and ANYOFL_FOLD could be moved to that extra space, but it would mean extra
+ * instructions, as there are currently places in the code that assume those
