New Cog VMs available

CogVM binaries as per VMMaker.oscog-eem.1370/r3386

Add the ARMv5/ARMv6 Cog Spur JIT VM!

Add explicit read barriers to primitives which access an argument as the

receiver (i.e. the mirror primitives).  Don't check if the actual receiver is

used.  Simplify failure where appropriate cuz the primitives will be retried.

Add -fwrapv to all linux gcc builds (to insist on 2's complement arithmetic)

and add makeallclean, making makeall do the dirty build.

Provide a -exitonwarn command line switch for the Mac and Unix VMs to allow for

CI testing of asserts.

Unix: restore the SCCS revision after the version number in -version output.

Spur:

Remember to count shrink requests

Cogit:

Fix bug in rewriting compiler primitives on module unload, etc.  The old code

didn't change the assignment to the primitiveFunctionPointer, which is needed

for correct management of failing primitive calls on Spur.  Simplify the post

compile hook to eliminate the label parameter; this is local to the Cogit.

ARM Cogit:

Use out-of-line literals for compactness.

Hey Eliot!

 

Does this VM allow Newspeak to run on the Raspberry Pi?

 

-Carl

[Robert Withers]

Yes, pleaaase Eliot!

I must release my ideas into the public domain, in hopes that y'all here with NewSpeak and Code For America may be able to make something of it, or even make sense of it, released under the MIT license. I pray you wonderful, wonderful, wunderkind can hook up and make it happen, perhaps in time for the Awards Ceremony, September 30th. ;-}

Who really knows what is possible? Only God Knows and that's beyond time.

God bless you,
Robert

The Newspeak and Squeak VMs are different so no.  I can include a Newspeak VM fir the pi if people want it, especially since u just got a pi 2, which I'm told is much faster.  So how much demand is there?  Rob, you want it [but there's nothing to stop you building your own ;)].  Who else?

[Robert Withers]

I'm disabled, they tell me. My experiences inform me I have a complete inability to code to completion. In addition, I am thoroughly tired of being solo in this life and coding pulls me in that direction.  So, I'm done.

I'll share these thoughts to the public domain, add pull in a couple of more sets of folks, in the form of Augur.net and swarm.org, and pray with all my heart for cross-cultural synergy.

Best Regards,
Robert

Please sail with us.

(I apologize for failing the challenge of email, in the previous post.  You see what I mean about having disability?)

Seems related to what's discussed on ietf: "Randomness sources for the IETF 2015-2016 Nomcom Selection". 

As well, I hope you folks on the Collective Dynamics of Complex Systems mailing list, considering a physical basis of virtualization, may find this to be a illuminating, optimizing search space: http://coco.binghamton.edu/.

Sincerely,

[Carl Gundel]

Hey Eliot,

 

I'm not in any real need to run Newspeak on the Raspberry Pi (I do own one) but I was only wondering if this new VM would make it work, out of enthusiastic curiosity more than anything.  :-)

 

Thanks,

 

-Carl

Dear Thom, Steven and Donald,

I wanted to share with you what has become of me, after all these years when you lit the spark in me. Here is a business plan I put together, released to the public in the off chance that dreams can become realized with the help of the village. God willing.

I've added my dedications:

Dedicated in the Loving memory of Sheridan A. Simon

Jefferson-Pilot Professor of Physics at Guilford College, Greensboro, NC

1947-1994

Thank you Guilford College Physics for being a bright light to so many,
Robert

Good morning brethren and sestren (http://www.thewilloftheancients.com/encyclopaedia/sestren-data-circuit)!

I hope this day is shining bright for you. My heart has always been with everyone's freely given efforts to create, since Slackware 0.96 with my boxes of 95 diskettes! :P My days coding are over, perhaps, as it's just to much for me. May everyone benefit, if there is any heart there in the ideas. Many folks would be thrilled to see it be realized and materialized, God willing. The principle is clear and right and true.

I've attached a business plan format of my ideas, that I've boiled down over a time. I'm releasing it under the MIT license, in hope, faith and love. I wanted to let you know.

Thank you,
Robert

Note that there's also a 64-bit Spur linux stack VM available for people (Hi Tobias!) who want to play with it.  The 64-bit image is in mirandabanda.org/files/Cog/SpurImages.

CogVM binaries as per VMMaker.oscog-eem.1388/r3390

Newspeak:

Enforce Newspeak access control in the interpreter, and enable it in Stack VMs.

Add a separate global lookup cache for non-ordinary sends.

Do proper lookups for self and super send misses from cogged code.

Do proper lookups for implicit receiver and outer send misses from cogged code.

Distinguish lookup for ordinary sends and for MNU processing in the JIT.

Skip private methods and stop on protected methods in ordinary lookup.

This should complete Newspeak access control.

Spur:

Add explicit read barriers to primitives which access an argument as the

receiver (i.e. the mirror primitives).  Don't check if the actual receiver is

used.  Simplify failure where appropriate because primitives will be retried.

Fix bogus assert in extSendBytecode.  Simplify

SpurMemoryManager>>classForClassTag:; its assert is superfluous.

ARM Cogit:

Add hardware FP support for ARM.

Runs all SUnit tests and assorted benchmarks ok, makes nbody 3X faster.

Probably some cleaning up to do, possibly more careful NaN handling etc.

Fix PIC parsing for out-of-line literals.  Add an assert to the closed PIC

prototype code to check all PIC parameters are accessible.  Add a

containsAddress: to abstract away the test for a target within the PIC.

Hi all,

These VMs enforce access control. Windows users will need a boot image from today; Mac and Linux users should be able to use any image from the past two months or so.

These include the Squeak 4.6 & 5.0 release candidate VMs.  Also included is a Newspeak ARM JIT VM.

CogVM binaries as per VMMaker.oscog-eem.1403/r3395

Fix long-standing bug in primitiveVMParameter for

setting, and hence allow Spur to set maxOldSpaceSize.

Spur:

Provide a limit to the size of old space on Spur.  Access maxOldSpaceSize

via vmParameterAt: 67 & command line parameter -maxoldspace.

Cogit:

Simplify pushRemoteTemp register management to be able to improve further the

overall register management.

These are new release candidates.  The Travis CI Newspeak bootstrap job caught a serious bug with become and process switch in the Spur VMs.

CogVM binaries as per VMMaker.oscog-eem.1405/r3397

Spur:

Make sure the post become action unforwards the Process in the activeProcess

inst var.  Add some more asserts to check.  Also follow the specialObjectsArray

after a pin become.

Generically use storePointerUnchecked: when storing nils into the process lists.

Apologies to anyone who has wasted time trying to use the Newspeak ARM VMs.  They're not yet ready for use as there's no Alien FFI support in the VM.  So they're not much use.  To spare anyone I've taken them down.  At least we know there's work to be done now.
