Hi,
A Squeak user reported crashes on OS X with Squeak 5.1. He downloaded the All-in-one bundle (Squeak5.1-16548-32bit). AFAICT his actions were not the immediate cause for the crash, he was just typing stuff in the workspace (the crash dump shows a key down event being sent to the VM, so this seems to be more of a VM <-> OS issue).
I’ve attached the crash dump he sent over Slack.
Cheers,
Max

I've just realized in the commit I forgot to revert the cogSpur VM
configuration. It is now compiled with both SqueakV3PlusClosures and
SistaV1 bytecode set, instead of only V3PlusClosures. Everything is
backward compatible.
Tell me if I should revert that in the next commit.

ClementBera uploaded a new version of VMMaker to project VM Maker:
http://source.squeak.org/VMMaker/VMMaker.oscog-cb.1920.mcz
==================== Summary ====================
Name: VMMaker.oscog-cb.1920
Author: cb
Time: 29 August 2016, 11:17:00.977074 am
UUID: 060760b1-6719-4e5b-b44d-55922703feda
Ancestors: VMMaker.oscog-cb.1919
This commit makes a difference between the usage of the sistaV1 bytecode set and the Sista VM. It is now possible to compile the VM with the SistaV1 bytecode set but without the SistaVM option. This way, one can use and stabilize:
- directed super sends
- full block closures
without using unsafe operations and traps. I believe we'll migrate to the sista runtime in multiple steps, and the first step is to use those features and have images compatible with those features without runtime optimizations.
The SistaV1 bytecode set allows to use directed super send and full block closures. Enabling the bytecode set enables those features. (SistaV1BytecodeSet option)
The SistaVM option, combined with SistaCogit, enables the profiling counters, the unsafe operations and traps. If disabled, the bytecodes from the SistaV1 bytecode set corresponding to traps or unsafe operations are considered unknown bytecodes.
All unsafe operations and traps related JIT code is now in SistaCogit. Those bytecodes are considered as unknown bytecodes in superclasses.
I've also changed some flag logic, as the flag marking optimized method is bit 16 (previously upper literal bit) and not the flag bit.

Log Message:
-----------
Mantis 0007819: Add Systemd socket activation patch for the VM in SocketPlugin
Patch by Max Leske <maxleske at gmail.com> and Nik Lutz, with socket type definitions as per oscog branch.
Note that ProvidedTCPSocketType is now defined as 65536, whereas the original patch (as implemented for cmsbox) defined it as 2.
This update is already present in oscog for Cog and Spur VMs.

Log Message:
-----------
Fix thunk return value in case of int64 or double for Win64
Note:
Win64 X64 uses registry rax for 1,2,4,8 bytes long int or struct return value
it uses xmm0 for float (single) or double floating point values
it uses a pointer passed as hidden first parameter (rcx) for anything else returned by value and copy the pointer to rax.
To pass a double back we use a call to a function taking double & returning double (fakeReturnDouble)
Any of these actions (passing 1 double or returning 1 double) would load xmm0, and we're done.
Except the function is no-op and could be entirely eliminated by aggressive optimizer.
It's thus vital to lay the function into another file and avoid any sort of link time optimization.
TO DO: This code currently does nothing for passing a short struct back by value in rax...
If the structure is long or odd sized, its address is expected as (hidden) first parameter (rcx), rather than on stack.
So the code does not look quite right yet wrt Win64 X64 ABI.
TO DO: the same kind of changes should be applied to X64 system V ABI

Hi,
We are very happy to make the following announcement:
Lam Research, a leading supplier of wafer fabrication equipment and services to the global semiconductor industry, is an experienced user of the Smalltalk programming language. Smalltalk is a key component in Lam's software control system for a broad range of the equipment it manufactures. Tudor Girba is a leading member of the tools and environment development effort in Pharo, having architected the Glamorous Toolkit for live programming. Eliot Miranda is author of the Cog virtual machine that underlies Pharo and other Smalltalk dialects.
Lam has engaged Tudor and Eliot to explore potential enhancements in Lam's use of Smalltalk. These enhancements range from running highly optimized Smalltalk on low cost, single board computers, to enhancing Lam's Smalltalk development practices with state-of-the-art live programming. During the engagement, Tudor and Eliot successfully moved a key communication component of the control system to Pharo. It was a challenging task aimed at extending the reach of Lam’s system to the Pharo world including the option of executing on ARM processors.
Cheers,
Tudor Girba, Eliot Miranda and Chris Thorgrimsson

Nicolas Cellier uploaded a new version of VMMaker to project VM Maker:
http://source.squeak.org/VMMaker/VMMaker.oscogLLP64-nice.1932.mcz
==================== Summary ====================
Name: VMMaker.oscogLLP64-nice.1932
Author: nice
Time: 18 August 2016, 10:53:27.516376 pm
UUID: 642ecc37-5300-3643-8d95-5acb4704c924
Ancestors: VMMaker.oscogLLP64-nice.1931
Fix generation of signed32BitIntegerFor: for 64 bits VM.
Not only constants must be extended to usqInt, but any expression whose type is shorter.
Also, use unsigned usqInt, rather than signed sqInt, because it's well defined behavior.
