regexec.c: regrepeat() change default: handling
The core of this function is a large switch() statement. Prior to this
commit, the default: case of it assumed that this meant that the
node-type was a zero-length node. It is safer to explicitly mention
all the cases you expect to handle, and have the default fail so that
you know sooner that you forgot to handle a situation. That is how all
other switch statements in this file are set up, and now this one is
too.
I added cases for all the node types in regcomp.c that are SIMPLE, and
hence could conceivably be handled by regrepeat(), and changed the
default: case to croak.
I considered doing an #ifdef DEBUGGING around this, but no other
switches() in the file do so, so I followed that paradigm.

regex: Make \R simple again.
Commit
565fc1bb88638c2490cdab7a1055007f6b2d577c was based on my
misunderstanding of what regrepeat() operates on. It is designed to
operate on nodes that are quantifiable without having to be
parenthesized. So, in 'a?', the node generated for 'a' is quantifiable
as-is, but if you want to quantify 'ab', you have to parenthesize them,
like '(?:ab)?'
\R is such a node, since you can say things like '\R+'. There was
indeed a bug, and that commit fixed it, but suboptimally.
This patch essentially reverts the commit mentioned above, and solves
the problem in a better way; it adds comments so that future
maintainters will be less likely to be led astray than I was.
It also adds a 'SIMPLE' flag for an expression that in my previous
misunderstanding didn't think was simple. (It's enclosed in
parentheses, and hence can serve as an operand to a quantifier.)

613a425dda0dc9e3f838151a5d796c902cfd922e

closely, I realized that there were longstanding problems there of a
similar nature. However, I was unable, for the most part, to come up
with tests that showed up these bugs, and that may explain why there
haven't been field reports for them. The situations that lead to
problems are typically caught before regrepeat() gets executed.
The problem was that the situation in this function is different
depending on whether the target string is encoded in UTF-8 or not, and
not all of the cases in the switch statement followed that. I have now
changed things, so that for both the UTF-8 and non-UTF-8 cases, the
switch is entered with things set up so that there is no extra set-up
needed for the most common situation; and comments now explain things.

regexec.c: Tighten loops in regrepeat()
regrepeat() is used to match some simple thing repeatedly in a row. In
the case of EXACTFish nodes, it will repeat a single character (and its
fold). Prior to this commit, it was using the full generality of
foldEQ_utf8() whenever the target was encoded in UTF-8. This full
generality requires quite a bit of processing. However, most
Unicode folds are of the simple variety containing just a character and
its upper- or lower-cased equivalent, and so the full generality of
foldEQ_utf8() is needed only comparatively infrequently.
This commit takes advantage of the newly added and enhanced
S_setup_EXACTISH_ST_c1_c2() to look at the character being repeated and
decide what level of generality is needed. regrepeat() then uses a loop
that is only as complicated as needed.
This also adds some asserts that the nodes contain exactly 1 character

regexec: Do less work on quantified UTF-8
Consider the regexes /A*B/ and /A*?B/ where A and B are arbitrary,
except that B begins with an EXACTish node. Prior to this patch, as a
shortcut, the loop for accumulating A* would look for the first character
of B to help it decide if B is a possiblity for the next thing. It did
not test for all of B unless testing showed that the next thing could be
the beginning of B. If the target string was UTF-8, it converted each
new sequence of bytes to the code point they represented, and then did
the comparision. This is a relative expensive process.
This commit avoids that conversion by just doing a memEQ at the current
input position. To do this, it revamps S_setup_EXACTISH_ST_c1_c2() to
output the UTF-8 sequences to compare against. The function also has
been tightened up so that there are fewer false positives.

This changes the macro isMULTI_CHAR_FOLD() (non-utf8 version) from just

However there are no such non-ASCII values, so the macro expansion is
unchanged. By changing the name, it becomes clearer in future commits

[perl #115260] Stop length($obj) from returning undef
When commit
9f621bb00 made length(undef) return undef, it also made it
return undef for objects with string overloading that returns undef.
But stringifying as undef is a contradiction in terms, and this makes
length inconsistent with defined, which returns true for such objects.
Changing this allows is to simplify pp_length, as we can now call
sv_len_utf8 on the argument unconditionally (except under the bytes
pragma). sv_len_utf8 is now careful not to record caches on magical
or overloaded scalars (any non-PV, in fact).
Note that sv_len is now just a wrapper around SvPV_const, so we use
SvPV_const_nomg, as there is no equivalent sv_len_nomg.

Make PerlIO::encoding handle cows
Commits
667763bdbf and
e9a8753af fixed bugs involving buffer realloca-
tions during encode and decode. But what was not taken into account
was that the COW flags could still be left on even when buffer real-
ocations were accounted for. This could result in SvPV_set and
SvLEN_set(sv,0) being called on an SV with the COW flags still on,
so SvPVX would be treated as a key inside a shared_he, resulting in
assertion failures.

Make PerlIO::encoding even more resilient to moving buffers
Commit
667763bdbf was not good enough.
If the buffer passed to an encode method is reallocated, it may be
smaller than the size (bufsiz) stored inside the encoding layer. So
we need to extend the buffer in that case and make sure the buffer
pointer is not pointing to freed memory.
The test as modified by this commit causes malloc errors on stderr
when I try it without the encoding.xs changes.

have Win32CORE use ALIAS/XSANY
Using XSANY in addition to a struct of strings, saved 650 bytes (.rdata

to string literals, use unsigned chars. Instead of creating new XSUB C
function stubs, one per forwarded sub, use the ALIAS/XSANY feature and
have only 1 XSUB which has many names. If a length aware version of newXS
is ever added to perl, the sub names's lengths already are available. See

regcomp.c: Don't set /i in start class unless /l
There is a deficiency in the optimizer in which it doesn't get rid of
flags that it should. One of these is if it should match /i or not.
Currently it always (perhaps not quite, I don't know) assumes that it
should match under /i, yielding false positives and slowing things down.
But a recent commit changed the flag that tells it to do this, so that it
only gets set if /l is also specified. There is already existing code to
work around the optimizer deficiency for /l. This commit just moves the
/i flag handling to that existing code, so it won't get invoked unless
/l is specified.
