regcomp.h: Free up bit; downside is makes locale ANYOF nodes large
There have been two flavors of ANYOF nodes under /l (locale) (for
bracketed character classes). If a class didn't try to match things
like [:word:], it was smaller by 4 bytes than one that did.
A flag bit was used to indicate which size it was. By making all such
nodes the larger size, whether needed or not, that bit can be freed to
be used for other purposes.
This only affects ANYOF nodes compiled under locale rules. The hope is
to eventually git rid of these nodes anyway, by taking the suggestion of
Yves Orton to compile regular expressions using the current locale, and
automatically recompile the next time they are used after the locale
changes.
This commit is somewhat experimental, done early in the development
cycle to see if there are any breakages. There are other ways to free
up a bit, as explained in the comments. Best would be to split off
nodes that match everything outside Latin1, freeing up the
ANYOF_UNICODE_ALL bit. However, there currently would need to be two
flavors of this, one also for ANYOFV. I'm currently working to
eliminate the need for ANYOFV nodes (which aren't sufficient,
[perl #89774]), so it's easiest to wait for this work to be done before
doing the split, after which we can revert this change in order to gain
back the space, but in the meantime, this will have had the opportunity

Magic flags harmonization.
In restore_magic(), which is called after any magic processing, all of
the public OK flags have been shifted into the private OK flags. Thus
the lack of an appropriate public OK flags was used to trigger both get
magic and required conversions. This scheme did not cover ROK, however,
so all properly written code had to make sure mg_get was called the right
number of times anyway. Meanwhile the private OK flags gained a second
purpose of marking converted but non-authoritative values (e.g. the IV
conversion of an NV), and the inadequate flag shift mechanic broke this
in some cases.
This patch removes the shift mechanic for magic flags, thus exposing (and
fixing) some improper usage of magic SVs in which mg_get() was not called
correctly. It also has the side effect of making magic get functions
specifically set their SVs to undef if that is desired, as the new behavior
of empty get functions is to leave the value unchanged. This is a feature,
as now get magic that does not modify its value, e.g. tainting, does not
have to be special cased.
The changes to cpan/ here are only temporary, for development only, to
keep blead working until upstream applies them (or something like them).

op.c:ck_grep: Remove unnecessary op_next assignments
ck_grep is a tangled mess and I am trying to simplify it, but at each
step it is not at all obvious what is happening.
grep/map with a block starts out like this:
grepstart
pushmark
null
scope/leave
block contents...
arg1
arg2
...
The if (o->op_flags & OPf_STACKED) at the top of ck_grep runs for
blocks. The firstkid var refers to the null above, and gets its
op_next set (this code was in ck_sort until recently [ck_grep used to
call ck_sort], and this particular op_next assignment was specific to
grep and map).
Later, the thing is fed through ck_fun, whose OA_CVREF case transforms
the tree into this:
grepstart
pushmark
null ← new op
null ← original null
scope/leave
block contents...
arg1
arg2
...
Then cUNOPx(cLISTOP->op_first->op_sibling)->op_first gets its op_next
set. By that point, that expression refers to the original null op,
so setting its op_next pointer to begin with seems pointless.
But it is not actually pointless. Removing that statement breaks
things. It turns out, as usual, that everything is more complicated
than it seems. Setting kid->op_next = (OP*)gwop in the block-specific
if statement after setting the first null op’s op_next pointer results
in op_next pointers like this (the newly-created grepwhile doesn’t
link to the grepstart yet at this point):
[grepwhile]
grepstart
pushmark
null -> block contents
scope/leave -> grepwhile
block contents...
arg1
arg2
...
So ck_fun’s OA_CVREF handling, when it calls LINKLIST, sees that the
original null op already has its op_next set and does nothing. With-
out it set, it copies it from the first kid, resulting in this (when
LINKLIST copies the op_next pointer out, it makes the kid it was cop-
ied from point to its sibling or its parent):
[grepwhile]
grepstart
pushmark
null
null -> grepwhile
scope/leave -> null (prev line)
block contents...
arg1
arg2
...
That nonsensical arrangement of op_next pointers basically prevents
the block from running, because the grepwhile’s other pointer, copied
from the first null’s kid, ends up pointing to the grepwhile itself.
If we also remove the kid->op_next = (OP*)gwop assignment from the
if(OPf_STACKED) block, then we end up with this after ck_fun:
[grepwhile]
grepstart
pushmark
null
null -> first op in block
scope/leave -> null (prev line)
block contents...
arg1
arg2
...
Then the op_next poiner from the first null’s kid is copied to
grepwhile’s op_other pointer, and everything works.
This also means we can remove the now-redundant LINKLIST call from the
if(OPfSTACKED) block, since ck_fun’s OA_CVREF handling also does that.
So now every vestige of the original call to ck_sort is gone.
This also means we no longer have to repeat NewOp(1101, gwop...).

Simplify ck_grep
Back in perl 5.000, ck_grep would call ck_sort (which was still the
case until
354dd559d99 just recently) and the latter would traverse
its way through the op_next pointers to find an op that tried to
escape the block, setting its op_next pointer to null. Then ck_grep
would traverse op_next pointers itself to find the place where ck_sort
stopped. That caused problems for grep which were fixed in
748a93069b
(perl 5.001). It was fixed by setting op_next to 0 on the first op,
so that the loop in ck_grep would not do anything. But that loop was
left there. This commit removes it.
There are also a couple of things I missed when disentangling
ck_grep and ck_sort in commit /
354dd559d9. I accidentally put
if (o->op_flags & OPf_STACKED) inside if (o->op_flags & OPf_STACKED).
And the OPf_SPECIAL flag was only being set for sort’s use, so ck_grep
doesn’t need to copy that.

op.c: Further simplify ck_sort
This code currently chases op_next pointers in the sort block to make
sure there is none that can point outside. To avoid getting stuck in
loops, it has to check for those explicitly.
Instead of nulling out any op_next pointer that points to the leave
op, we can simply turn the leave into a null op (which we already do)
and have the leave op’s op_next pointer point to nothing.
That produces the same result in the end: Execution of the sort block
is prevented from running rampant and escaping out of it, but exits
the runloop instead, returning control to pp_sort.

[perl #113710] Make __SUB__ work in sort block
When the peephole optimiser encounters a __SUB__, it looks to see
whether the current sub is clonable. If it is not, it inlines the
__SUB__ as a const op.
This works most of the time. A forward declaration will cause the sub
definition to reuse the existing stub. When that happens, the sub
visible during compilation in PL_compcv is not the sub that the
op tree will finally be attached to. But the peephole optimiser
is called after that, with PL_compcv set to the other CV (what
was a stub).
ck_sort was calling the peephole optimiser on the sort block ahead of
time. So this caused __SUB__ to point to the wrong subroutine.
By removing the CALL_PEEP call from ck_sort and adding logic to the
peephole optimiser itself to traverse the sort block (it is not in the
usual op_next chain), this bug is eliminated.
I modified the DEFER macro to work as a single statement. You don’t
want to know how much time I spent debugging the bus errors that were
occurring because if(foo) DEFER; didn’t do what I though.
It turns out that grepstart and mapstart, which also use ck_sort,
had their blocks go through the peephole optimiser twice, because
grepwhile already has special-casing in the peephole optimiser.
This also has the side-effect of making map and grep slightly more
efficient, in that they no longer execute a scope op (which is just
pp_null). By temporarily disconnecting the subtree before running the
optimiser, ck_sort was hiding a possible optimisation (skipping the
scope op).

fix RT#114068 optimizer handles MEOL in middle of pattern improperly
It seems that under certain circumstances the optimiser handles the
MEOL operator (what $ turns into under /m), improperly including
things that follow. This results in compilation like this:
Compiling REx "( [^z] $ [^z]+ )"
Final program:
1: OPEN1 (3)
3: ANYOF[\x00-y{-\xff][{unicode}0100-INFINITY] (14)
14: MEOL (15)
15: PLUS (27)

29: END (0)
anchored ""$ at 2 stclass ANYOF[\x00-y{-\xff][{unicode}0100-INFINITY]
Where the '""$ at 2' is sign of the bug. The problem is that the optimiser
does not "commit" the string when it encounters an MEOL, which means that
text that follows it is included. This has probably always been wrong as
$ is a multichar pattern (it matches before an \n or including an \n). This
failure to commit then interacts with the implementation for PLUS leading to
an incorrect offset. By adding a SCAN_COMMIT() as part of the optimisers
handling of EOL constructs this problem is avoided. Note that most uses of
$ were ok due to other reasons.

SAVEFREEOP calls near the top of newATTRSUB) will make the slab writa-
ble again. At that point, the BEGIN block has already been run and
its slab freed. Maybe slabs belonging to BEGIN blocks can be made
read-only later.
Under PERL_DEBUG_READONLY_OPS, op slabs have two extra fields to
record the size and readonliness of each slab. (Only the first slab
in a CV’s slab chain uses the readonly flag, since it is conceptually
simpler to treat them all as one unit.) Without recording this infor-
mation manually, things become unbearably slow, the tests taking hours
and hours instead of minutes.

Ensure wildcard expansion is enabled for perlglob.exe on Windows
This is provided by linking in setargv.obj for Visual C++, which the
makefiles already do, but for MinGW(-w64)/gcc we must explicitly ensure
that wildcard expansion is enabled rather than relying on the C-runtime
defaults of the particular compiler suite in question.
This currently only seems to be necessary for the automated build of the
MinGW-w64 cross-compiler (other builds have it enabled by default anyway),
but there's no harm in making sure for others too.

Expand $^O at build time when generating Config::_V()
Config::_V() is how perl -V is implemented internally, and is called called

so conditionals dependent on the value of $^O will always take the same

VMS and Cygwin specific code except on those platforms. (But add a sanity
test in Config::_V() to ensure that the runtime $^O has the correct value -

Improve support for building on Windows with mingw-w64.sf.net binaries
The cross-compiler has headers and libraries in a sub-directory called
x86_64-w64-mingw32\, which is also copied to mingw\ in the automated
builds but not in other builds (e.g. rubenvb's build), so rely on the
folder which is always present.
The DLLs required for op\taint.t to work are nomrally found in \bin\, but
for the cross-compiler are found in the same folder as the libraries since
they are 64-bit DLLs, whereas the compiler binaries themselves are 32-bit.
With these fixes we now support the following MinGW/gcc compilers:
Native 32-bit compilers (WIN64=undef GCCCROSS=undef): mingw.org, rubenvb's
build of mingw-w64.sf.net, Mark Dootson's build of the same (used in
Strawberry Perl).
Native 64-bit compilers (WIN64=define GCCCROSS=undef): rubenvb's build of
mingw-w64.sf.net, Mark Dootson's build of the same (used in Strawberry
Perl).
32-bit cross-compilers producing 64-bit binaries (WIN64=define
GCCCROSS=define): rubenvb's build of mingw-w64.sf.net, the automated build
of the same.
There is currently no automated build of a native 64-bit compiler on
mingw-w64.sf.net, and their automated build of a native 32-bit compiler is
not currently supported since it uses an anomalous naming convention
compared to the other options above.

Correct err msg when calling stub w/no autoload fb
If an AUTOLOAD subroutine loads a sub by assigning to the glob, there
may be code elsewhere that has a reference to a stub, that is now
assigned over. To cope with this situation, calls to undefined sub-
routines will fall back to whatever sub is in the subroutine’s owner
typeglob. This has been the case since Perl 5.000.
But the error message that occurs if the typeglob happens to have no
sub in it is wrong:
$ perl -e '
my $foosub = \&foo;
undef *foo;
&$foosub;
'
Not a CODE reference at -e line 4.
as opposed to this:
$ perl -e '
my $foosub = \&foo;
&$foosub;
'
Undefined subroutine &main::foo called at -e line 3.
They should both produce the same error message, because $foosub is a
code reference, albeit without a body.

[perl #113016] Parse CORE::foo::bar as a bareword
CORE::print::foo was being parsed as CORE::print followed by
::foo, making it impossible to call a global override directly as
CORE::GLOBAL::uc().
The logic in toke.c that does the CORE:: special-casing was faulty.
This commit fixes it, by checking for a package separator after the
potential keyword.
That d = s part of the KEY_CORE case in yylex was added in perl 5.001
(
748a9306) but apparently wasn’t doing anything. That means I get to
move it before s+=2, now that I have a use for it.

rv2cv hooks should not create 2nd-class subs
$ perl5.17.2 -Mblib -e 'sub foo{}; foo $bar; use Lexical::Sub baz => sub{}; baz $bar'
Can't call method "baz" on an undefined value at -e line 1.
$ perl5.17.2 -Mblib -e 'sub foo{}; foo bar; use Lexical::Sub baz => sub{}; baz bar'
Can't locate object method "baz" via package "bar" (perhaps you forgot to load "bar"?) at -e line 1.
So if you use Lexical::Sub, your sub doesn’t get to participate in
determining whether ‘foo $bar’ or ‘foo bar’ is a method call.
This is because Lexical::Sub uses an rv2cv hook to intercept sub
lookup. And toke.c:S_intuit_method thinks there cannot be a CV with-
out a GV (which was the case when it was first written).

f7461760 introduced this rv2cv hooking for bareword lookup, but
