ImageFormat represents the requirements of the image in terms of capabilities that must be supported by the virtual machine. The image format version is saved as an integer value in the header of an image file. When an image is loaded, the virtual machine checks the image format version to determine whether it is capable of supporting the requirements of that image. The image format version value is treated as a bit map of size 32, derived from the 32-bit integer value saved in the image header. Bits in the bit map represent image format requirements. For example, if the image sets bit 15 to indicate that it requires some capability from the VM, then the VM can check bit 15 and decide whether it is able to satisfy that requirement. The base image format numbers (6502, 6504, 68000, and 68002) utiliize 10 of the 32 available bits. The high order bit is reserved as an extension bit for future use. The remaining 21 bits are used to represent additional image format requirements. For example, the low order bit is used to indication that the image uses (and requires support for) the platform byte ordering implemented in the StackInterpreter (Cog) VM.

V3: desiredHeapSize is the total size of the heap. Fail if the image has an unknown format or requires more than the specified amount of memory. Spur: desiredHeapSize is ignored; this routine will attempt to provide at least extraVMMemory's ammount of free space after the image is loaded, taking any free space in the image into account. extraVMMemory is stored in the image header and is accessible as vmParameterAt: 23. If extraVMMemory is 0, the value defaults to the default grow headroom. Fail if the image has an unknown format or if sufficient memory cannot be allocated. Details: This method detects when the image was stored on a machine with the opposite byte ordering from this machine and swaps the bytes automatically. Furthermore, it allows the header information to start 512 bytes into the file, since some file transfer programs for the Macintosh apparently prepend a Mac-specific header of this size.

Mac PPC Carbon VM resuscitation part 2: status and two questions
by Tim Johnson 26 Jul '20

26 Jul '20

Hi all, Continuing down the dusty road of bringing the Mac Carbon VM back to life on PowerPC for research and educational purposes. Here's a status update and two questions. First, status update: I've concluded that the VM will continue to build with very few changes up to VMMaker 4.4.14, but then a VM that locks up at interpret() as of 4.4.15. I then fast-forwarded to VMMaker 4.7.8 and again have a working VM. But, this has required a few changes to methods and I have had to stop building a few more plugins (to be expected, I think!), namely B3DEnginePlugin and SoundGenerationPlugin. The VM built with VMMaker 4.7.8 passes more tests in Squeak 4.6 than those built with previous versions, but also happens to be failing one test which may be consequential: LargeNegativeIntegerTest>>#testMinimumNegativeIntegerArithmetic I've been working lately within a 4.6 image converted to 6504 format (thanks for the tip, Dave!). Note that my build product, even at 4.7.8, still can't natively launch & interpret a 6505-format image like the release version of 4.6 from files.squeak.org. Nor can it launch & interpret Squeak5.2-V3-18216.image. Squeak5.2-V3-18216.image is already in 6504 format, so I suspect something else to be at fault (I just force-quit it now, and found it having trouble at _primDigitMultiplyNegative and _cDigitMultiplylenwithleninto). May be worth further research on my part. By VMMaker 4.7.8, my VM build workspace is as follows: vmm := (Smalltalk at: #VMMaker) default. " We can't cascade here. Maybe was fixed in later versions." vmm deleteEntireGeneratedTree. vmm makeAllModulesInternal. vmm internalModules removeAll: #( ADPCMCodecPlugin B3DEnginePlugin ClipboardExtendedPlugin CroquetPlugin FFIPlugin FloatMathPlugin FileCopyPlugin ImmX11Plugin LocalePlugin Mpeg3Plugin QuicktimePlugin SlangTestSupportSSIP SlangTestSupportPlugin SoundGenerationPlugin TestOSAPlugin). vmm generateEntire. ((Smalltalk at: #Gnuifier) on: (FileDirectory default fullName), '/src/ vm') gnuify. The script I used for getting a VMMaker build image going in a "stock" Squeak 4.5/4.6 image is attached. It was based off of (and, I believe, clarifies or codifies) the instructions found in platforms/ Mac OS/vm/Documentation/readme.txt re: proper load order. Question 1: InterpreterPrimitives>>#signed64BitValueOf: uses usqLong which wasn't defined in any of my platform support code: value := 0 - (self cCoerce: value to: 'usqLong'). I changed it to: value := 0 - (self cCoerce: value to: 'unsigned sqLong'). ...does that seem equivalent? Should I have usqLong defined somewhere in my platform support code? It is used more heavily in opensmalltalk-vm, but I can't seem to find where it is defined over there, either. Question 2: LargeIntegersPlugin>>#digitMontgomery:times:modulo:mInvModB: was introduced in VMMaker 4.4.20 (VMMaker-dtl.233) and later bugfixed in VMMaker 4.5.3 (VMMaker-dtl.239) However, this method calls "self error:" as follows: firstLen <= thirdLen ifFalse: [^self error: 'firstLarge must be less than thirdLarge']. secondLen <= thirdLen ifFalse: [^self error: 'secondLarge must be less than thirdLarge']. (mInv >= 0 and: [mInv <= 255]) ifFalse: [^self error: 'mInvMod256 must be between 0 and 255']. which results in an undefined symbol _error when building this VM. What would be the proper way to address this? Find a place to implement error() in the VM cross/ or platform/ sources (or steal from newer support code)? Or to change the call to self error: to something else? To get the VM building, I've just hand-patched LargeIntegers.c as follows: if (!(firstLen <= thirdLen)) { /* return error("firstLarge must be less than thirdLarge"); */ return interpreterProxy->success(false); } if (!(secondLen <= thirdLen)) { /* return error("secondLarge must be less than thirdLarge"); */ return interpreterProxy->success(false); } if (!((mInv >= 0) && (mInv <= 255))) { /* return error("mInvMod256 must be between 0 and 255"); */ return interpreterProxy->success(false); } Lastly: I'm tempted to ask if anybody ever tried controlling the Xcode project via AppleScript, back when Xcode was still a big part of building the Mac or iOS VM. Maybe maximum effort with minimum payoff, but could be interesting or fun to automatically enable/disable plugin sources based on VMMaker(Tool) selections, and automatically trigger build/clean from within the Squeak image. Thanks, a Tim
