Im toying (once again) with the notion of combining op_next and op_sibling
into a union, which could save non-trivial memory for optrees.
A naive estimate is 20%

Its not clear what the value of this savings is - theres generally
a lot less code than data, so the total memory saved may not be worth 
fussing for.
OTOH, maybe mod-perl servers could materially benefit.
If you have a use-case where code-memory savings could matter, please 
say so.
Im just scratching an itch, but I'll be damned if Im gonna create a rash.


* optrees are created using op-siblings to tie the OPs together,
so op-siblings are integral to this.

* Perl_linklist traverses this 'syntax' tree, and sets op-next pointers
to give the execution order for that optree.  op-sibling pointers are
basically unneeded after that.

* I just lied - theyre needed for uninit-var chasing, and perhaps other 
things.
But - theyre rarely needed, and could be fetched from elsewhere.  
Further, the
cost of that fetch is nearly irrelevant, since its an error-reporting / 
diagnostic feature.



Anyway, the 1st patch in this series is pretty straightforward, the 
interesting bits are here:
(patch is compressed, cuz its ~ 90k otherwize)

Depending on the value of *OP_NEXT_SIBL_IMP*, we get
0 - original code
1 - a sub-struct op {OP* next,  sibling}
2 - a sub-union
along with  4 macros which hide those variations.
( building both 0,1 uses the compiler to prove that abstraction is 
complete )
    Configure -des ... -Accflags="-DOP_NEXT_SIBL_IMP=1"

With patch applied, bleadperl builds fine and tests pretty good for both 
0 and 1;
2 failures;
ext/B/t/bytecode.....................................FAILED at test 1
ext/B/t/concise......................................ok
ext/B/t/concise-xs...................................# Looks like you 
planned 1588 tests but ran 1 extra.
FAILED--expected 1588 tests, saw 1589

    concise-xs.t   (trivial, due to extra B constant inadvertently 
created (probly some patch cruft))
    bytecode      I dont get this one.. tested verbosely, it gets SEGV.
          I think its fixable, but Im looking ahead ATM.


WRT the RARELY NEEDED bits ..  (heres where it gets tricky/speculative)

it should be possible to:

-  collect op-siblings in  Perl-linklist, stuff them into temporary storage
    Im trying to use PTR_TBL code, exported from sv.c,
    this seems non-interfering, since its compile-time, whereas the 
threads use of that table
    is run-time. (speculating;-)
    IIRC, I tried to stuff the data directly into PL_compiling, but 
couldnt convince myself
    that it was workable ( recollection of confusion is all that remains )

- catch COPs in Perl-linklist, at which point (I hope) the op-next chain 
is complete
    for that statement, and could be walked.  So, walk the chain, and 
lookup the sibling
    for each that was previously collected (we'd also delete those entries).

- attach the collected siblings to the COP (with a newly added field)
    Im envisioning an array, with siblings stored at indexes 
corresponding to the walk-steps

Im stuck somewhere in the middle of the above, and could use some advice ..


Continuing on speculative path ( we have to get further for the above to 
be valuable)

- with sibling info stored off the COP, it should be possible to fix 
find_uninit_var()
to get the sibling data it needs, assuming that closest_cop will work 
there (no obvious reason it shouldnt)
There look to be 5 calls to PERL_OP_SIBLING that need to be replaced.

[jimc@harpo ns-cop-sibl]$ egrep -n 'OP_SIBLING|find_uninit_var' sv.c
11855:=for apidoc find_uninit_var
11875:S_find_uninit_var(pTHX_ OP* obase, SV* uninit_sv, bool match)
11913:          return find_uninit_var(cUNOPx(obase)->op_first,
11985:  return find_uninit_var(cBINOPo->op_last, uninit_sv, match);
11991:      return find_uninit_var(cBINOPx(obase)->op_last, uninit_sv, 
match);
12062:  return find_uninit_var(cBINOPx(obase)->op_first, uninit_sv, match);
12067:      o = PERL_OP_SIBLING(o);
12069:  if (!PERL_OP_SIBLING(o)) {
12108:      o = PERL_OP_SIBLING(PERL_OP_SIBLING(o));
12137:  for (kid=o; kid; kid = PERL_OP_SIBLING(kid)) {
12153:      return find_uninit_var(o2, uninit_sv, match);
12157:      sv = find_uninit_var(o, uninit_sv, 1);
12160:      o = PERL_OP_SIBLING(o);
12183:      varname = find_uninit_var(PL_op, uninit_sv,0);



I for one would find a lot of guidance/value if someone knowledgeable would
add a handful of assertions which would document the subtle invariants 
buried in the optrees.
    op_assert( o->op_sibling == o)
    op_assert( o->op_next == o)
        This occurs a lot.  its also counterintuitive.
 
Id expect some of the properties thus exposed to be representable by flags
(or some small set of states), with the useful ones reserved out of OP's 
spare-bits


Once siblings are out of OP (and reachable via the relevant COP),
further optimizations might be possible, but I'll refrain from too much 
more speculation.




The 2nd patch hacks at Perl_linklist, adding printfs, and yielding this:

[jimc@harpo ns-cop-sibling]$ ./perl -Ilib -e 'print"foo",$_+2; 
print"bar",$_-3'

   COP 90f5ab0 -> 90f3160 print
   90f5ab0 nextstate s:90f3160 n:90f5ab0
    COP 90f5ab0 -> 90f3160 print
   90f3160 print s:90ec070 n:0
    90f5a98 pushmark s:90f3190 n:90f5a98
    90f3190 const s:90f3210 n:90f3190
    90f3210 add s:0 n:90f31b0
    90f3160 print s:90ec070 n:90f5a98
   COP 90ec070 -> 90ed078 print
   90ec070 nextstate s:90ed078 n:90ec070
    COP 90ec070 -> 90ed078 print
   90ed078 print s:0 n:0        
    90f5b08 pushmark s:90f5b80 n:90f5b08
    90f5b80 const s:90f5c00 n:90f5b80
    90f5c00 subtract s:0 n:90f5ba0
    90ed078 print s:0 n:90f5b08
   90f5ae8 leave s:0 n:90f5c90


if you suppress these prints, the code passes all but the 2 tests id'd 
above.

op_assert( o->op_next == o)
This occurs a lot above, I dont get it.  Is there another, final step ?
Also - its obvious that this could be replaced by a flag

NORMAL is o->op_next..

+=head1 Implementation: out-of-OP op-siblings
+
+In the bottom up up complier pass, perly.y emits op-twigs, setting
+op-type/class specific pointers in each OP to link them together
+according to the expression just parsed.  Sequences of
+
+optrees are generated using op_sibling and 
+represent both sequential and expression dependencies.  The execution
+order pass relinks the tree of OPs for fast execution, using the
+op_next pointer.
+
+Our premise is that sibling pointers are used rarely after op_next is
+set, so, at listlink()-age time, we copy op_sibling to an associative
+array, and intercept later reads.  This allows us to instrument that
+read, find out who is using the value, and optimize later, starting
+with removing in-OP storage for the pointer and getting it from the
+hash.  This shrinks the optree by ~20%, and may have other benefits.
+
+=head2 Implementation: patch development
+
+ 1.abstract all refs to op_next, op_sibling with macros
+ .  PERL_OP_NEXT,    PERL_OP_SIBLING
+ .  PERL_OP_SETNEXT, PERL_OP_SETSIBLING
+ . set OP_NEXT_SIBL_IMP to 0,1,2: to choose pair, struct, union reps
+
+ 2.extend COP, adding struct OpPair {next; sibl} ops[30]
+ .  populate it in linklist
+
+This wont work as is; in linklist(), assert(PL_curcop == &PL_compiling),
+so theres no COP context
+
+
+ 3.compile vs runtime (TBC)
+ .  PERL_OP_SIBLING should call instrumentation
+ .  use IN_PERL_RUNTIME to toggle PERL_OP_SIBLING defn
+
+=head2 Future Optimizations
+
+At this point (patch 2), the patch increases total memory use, but
+we're looking forward to several optimizations:
+
+1 not all ops have siblings, only those that do get added
+
+2 we hope that op-shrink, and segregating hot fields from cold, will
+  improve cache performance, though cache arguably works much better
+  on C code, and pp_code probably dwarfs the 20% opcode savings.
+
+3 analysis of the uninit-var feature may reveal that only some ops
+  need to be hashed to support the reporting for the vars in a given
+  code block.
+
+4 we can add a feature to allow the coder to suppress the hashing of
+  siblings entirely, for use on well-tested code.
+
+5 OpPair storage can be unioned with op_siblings vector, which its
+  converted to if/when linklist(op) acts upon COPs.  At this point,
+  the op can be shrunk to fit the op_sibling vector actually needed.

Gosh, no replies. Well, from my point of view this adds a lot of
complexity for no given reason. Is it actually any better?

Thanks for responding Leon,

Its certainly a fair question, and one Ive been pondering myself.

Your question prompted me to look for my own estimate of code-memory size,
specifically at process size, b4 and after loading Phalanx100.

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
b4
  531 jimc      15   0  9496 5976 1528 S  0.0  1.2   0:00.37 perl
after
  531 jimc      23   0  100m  90m 4128 S  0.0 17.9   0:06.91 perl


Thats 90 MB of growth, enough I think to warrant further discussion.
Ive attached my script, hopefully its repeatable.

thanks again,
jimc

I don't really see what point you are trying to make here. Yes, if you
load tons of  modules you will use tons of memory. What you haven't shown,
is
(a) how much does that 100m shrink by if op_sibling and op_next are
combined?
(b) what proportion of total memory would that 100m be if the modules
were actually used in anger - normally you only load modules to use them
for something, at which point you're creating lots of SVs atc.

a) I cant answer, since Ive not been able to s/struct/union/ and get 
something working.
To demonstrate 20 MB of savings (the 20% WAG), Id have to be further along.
You may infer that Im looking for clues, none heard yet :-(

b) is a low-effort existential proof.  For more reality, substitute a 
large mod-perl app, with 30 or 40
processes running simultaneously.  I dont have such a setup, but surely 
someone here does,
and could run top on the box and send results.
Besides, the point was to separate data (which has already been 
squeezed, thanks NickC)
from code, not to give a real-world example.

If this is seen as a purely hand-waving non-solution to a non-problem,
then Ill look elsewhere for my entertainments.
OTOH,
If you/someone could look at 2nd patch, and help me understand why the 
prints I added to Perl_linklist
show next == self, I might be able to make some progress towards a).

Im resending patches:
1- drops the bytecode bits that were recently dropped from bleadperl.
2- disables the PerlIO_printfs added into Perl_linklist, so that make 
test passes.

I'll concede that merely relocating op-siblings into the closest-cop 
will not, by itself,
save any memory.  It should improve cache-locality, which may not be 
visible,
except perhaps with cachegrind.  But eventually, it should be possible 
to add
a 'no uninit-var-reporting' feature, which drops all op-siblings, for 
use where its warranted.

b) is a low-effort existential proof.  Substitute a large mod-perl app, 
with 30 or 40
processes running simultaneously for more reality.  I dont have such a 
setup,
but surely someone here does, and could run top on the box.
I dont think we need to go about 'proving' that no case exists.
Besides, the point was to separate data (which has already been 
squeezed, thanks NickC)

+=head1 Implementation: out-of-OP op-siblings
+
+In the bottom up up complier pass, perly.y emits op-twigs, setting
+op-type/class specific pointers in each OP to link them together
+according to the expression just parsed.  Sequences of
+
+optrees are generated using op_sibling and 
+represent both sequential and expression dependencies.  The execution
+order pass relinks the tree of OPs for fast execution, using the
+op_next pointer.
+
+Our premise is that sibling pointers are used rarely after op_next is
+set, so, at listlink()-age time, we copy op_sibling to an associative
+array, and intercept later reads.  This allows us to instrument that
+read, find out who is using the value, and optimize later, starting
+with removing in-OP storage for the pointer and getting it from the
+hash.  This shrinks the optree by ~20%, and may have other benefits.
+
+=head2 Implementation: patch development
+
+ 1.abstract all refs to op_next, op_sibling with macros
+ .  PERL_OP_NEXT,    PERL_OP_SIBLING
+ .  PERL_OP_SETNEXT, PERL_OP_SETSIBLING
+ . set OP_NEXT_SIBL_IMP to 0,1,2: to choose pair, struct, union reps
+
+ 2.extend COP, adding struct OpPair {next; sibl} ops[30]
+ .  populate it in linklist
+
+This wont work as is; in linklist(), assert(PL_curcop == &PL_compiling),
+so theres no COP context
+
+
+ 3.compile vs runtime (TBC)
+ .  PERL_OP_SIBLING should call instrumentation
+ .  use IN_PERL_RUNTIME to toggle PERL_OP_SIBLING defn
+
+=head2 Future Optimizations
+
+At this point (patch 2), the patch increases total memory use, but
+we're looking forward to several optimizations:
+
+1 not all ops have siblings, only those that do get added
+
+2 we hope that op-shrink, and segregating hot fields from cold, will
+  improve cache performance, though cache arguably works much better
+  on C code, and pp_code probably dwarfs the 20% opcode savings.
+
+3 analysis of the uninit-var feature may reveal that only some ops
+  need to be hashed to support the reporting for the vars in a given
+  code block.
+
+4 we can add a feature to allow the coder to suppress the hashing of
+  siblings entirely, for use on well-tested code.
+
+5 OpPair storage can be unioned with op_siblings vector, which its
+  converted to if/when linklist(op) acts upon COPs.  At this point,
+  the op can be shrunk to fit the op_sibling vector actually needed.

what you could do is temporarily add an extra ptr field to BASEOP, and see
how much the 100m grows by; we can then assume it would shrink by the same
amount.

B::Deparse and thus Data::Dumper and Data::Dump::Streamer both care
about ->sibling existing in normal, not debugging runtime. Do your
processes need to be able to deparse perl?

IOW - trivial  growth.

This may be due to the 99m being dominated by XS code,
which is probably the point you were making earlier..  :-[

As time permits, I'll construct a use-pure-perl-mods script, and see if 
it shows anything more.

Yes, the hard parts remain, but now theres cause to look more closely.

A couple of comments. First, I'm not sure you meant this: your eval string
gets compiled as:

    $sum[\"$i"] = $in1[\"$i"] + $in2[\"$j"];
    ... etc

    rather than 

    $sum[3] = $in1[3] + $in2[7];
    ... etc

Second, its not a very realistic example, since you just have one
extremely big sub that contains no lexical vars.

Once, long ago, I worked on an app that data-dumped code. 
Not since then.  Its not a must-have for me.

But I dont want to get the dialog hung on absense/presence of any given 
data.
My hope is that we can, in discrete steps;
-abstract it
-move it into cop
-compress it
-optionally toss it - for 99% of time when its not needed.



For curiosity, I wrote attached script to instrument B::OP::sibling,
and collect the siblings found in &foo() into %seen.  Most are seen 
once, some 2 or more times.
I wanted to see if there were any that werent traversed.

I am puzzled that Im counting 27 siblings, and only 16 ops
(The late redef of B::OP::sibling cut it from ~240 siblings)

.....
&$x();
print Dumper(\%seen);
print "got $opcount OPs\n";
print 'got ', scalar keys %seen, " siblings\n";
'???';

got 16 OPs
got 27 siblings

Any comments ?

You forgot to count all the trailing NULL siblings. Those B::NULL ops
are really just null pointers prettied up into objects.
