These include 64-bit VMs whose Smalltalk execution and FFI are functional.�� However, their SocketPlugin is more than somewhat broken.�� Executing the SocketPlugin tests results in a hard lockup, at least on Mac OS X.�� This is my next focus for 64-bits.

CogVM binaries as per VMMaker.oscog-eem.1700/r3632

General:

Fix serious bug in jitted perform: primitive.�� Thanks to Stephane Rollandin

for finding and to Levente Uzoni for diagnosing the bug.�� If the argument

count is one greater than the max number of register arguments (2 in Spur,

hence perform:with:with:) then the code to remove the receiver and arguments

from the stack neglects to remove the receiver and selector.

Spur:

Fix special selector arithmetic and comparison in the 64-bit Cogit.�� My original

code for genJumpNotSmallIntegersIn:andScratchReg: merely jumped if the tags

differed, hence not jumping if both arguments were SmallFloat64s (or both

Characters).�� The new code requires an additional scratch register;

hence add genJumpNotSmallIntegersIn:andScratch:scratch:.

Fix bug in markAndTraceWeaklingsFrom:.�� Fields of weaklings may be immediate

so must use followOopField:ofObject: not followObjField:ofObject:.

Fix https://pharo.fogbugz.com/f/cases/17536/VM-Crash-when-adding-an-iVar-to-a-subclass-of-SystemAnnouncement.

When weaklings (and when ephemerons) are scan-marked forwarders must be coped

with.

64-bit VMs:

Fix a bug in printHex: for 64-bits (faulty arithmetic).

ThreadedFFIPlugin:

Fix the remaining 64-bit issues in the ThreadedFFIPlugin.�� The X64SysVFFIPlugin

now passes the test suite.�� Hence include the FFI plugin in 64-bit VMs.

Make the SqueakFFIPrims plugin internal in the Mac pharo builds.

Mac VMs:

Have the Mac OS X build install Localizable.strings.�� Add versions for

Newspeak, Pharo and Squeak.�� Rename the key to SelectImagePanePrompt.

Temporarily disable the Serial plugin in the Pharo Mac VM until we can track

down the relevant platforms/iOS support for the Pharo extensions.

Fix argument access on the iOS platform (Mac OS VMs).
