Also some 64-bit JVMs use "compressed oops". Because data is aligned to around every 8 or 16 bytes, three or four bits of the address are useless (although a "mark" bit may be stolen for some algorithms). This allows 32-bit address data (therefore using half as much bandwidth, and therefore faster) to use heap sizes of 35- or 36-bits on a 64-bit platform.
On the otherhand, I found this link. According this, it is possible to compile 64-bit code on a 32-bit machine. But I am not clear on how this is done plus if compiling on a 32-bit machine will also guarantee execution on the same.
Additional Note: However, it turns out this didn't actually solve my problem. The 64-bit toolset ate up all the memory on my machine and forced me to need to reboot. When I rolled back the latest changes to the code, it compiles using 2.8GB for the 32-bit compiler, and compiles using 4.2GB for the 64-bit compiler (the latest code consumed 6.4GB before freezing my task manager on my 8GB machine). I'll be looking through the new code and attempting to figure out why so much more memory was needed.
This was an essential change for me since I am using a RPi 3 with multiple containers, one of them being the Unifi Controller, which will drop out of support on 32-bit due to some issues with mongodb. The whole stack had to go to 64-bit.
The questions to this thread are if any of the previous considerations about 32 vs 64-bit should be revisited, and whether openHABian 64-bit has a now brighter future ahead, to be worth the investment of effort for a new release.
I know that it would have to be completely emulated and would run like a dog - but slow performance isn't necessarily an issue as I'm just interested in testing some of my background services code on 64-bit platforms.
You can't run a 64-bit VM session on a 32-bit processor. However, you can run a 64-bit VM session if you have a 64-bit processor but have installed a 32-bit host OS and your processor supports the right extensions. The tool linked above will tell you if yours does.
I honestly doubt it, for a number of reasons, but the most important one is that there are some instructions that are allowed in 32-bit mode, but not in 64-bit mode. Specifically, the REX prefix that is used to encode some instructions and registers in 64-bit mode is a byte of the form 0x4f:0x40, but in 32 bit mode the same byte is either INC or DEC with a fixed operand.
Because of this, any 64-bit instruction that is prefixed by REX will be interpreted as either INC or DEC, and won't give the VMM the chance to emulate the 64-bit instruction (for instance by signaling an undefined opcode exception).
The only way it might be done is to use a trap exception to return to the VMM after each and every instruction so that it can see if it needs special 64-bit handling. I simply can't see that happening.
I downloaded the new Teams and it defaulted to a x86 (32-bit) installer for some reason. Is this all that's available? How do I get the 64-bit version? I don't see it on the website anywhere. In the past i've read that Teams matches up with if your Office is 32-bit vs 64-bit, and I definitely have 64-bit installed. (Office 365)
Click here to download the latest (2.43.0) 64-bit version of Git for Windows. This is the most recent maintained build. It was released about 1 month ago, on 2023-11-20.
I upgraded my STCK1A32WFC from Windows 8.1 to Windows 10 20H2 a few years ago. However, there is still a Windows Upgrade Assistant link on the desktop. Is this good for anything, or should I delete it? In particular, the system properties say that I have 32-bit Windows installed on a 64-bit processor. Wouldn't I be better off with a 64-bit Windows installation? If so, how can I upgrade my 32-bit installation to a 64-bit one?
To run a 32-bit executable file on a 64-bit multi-architecture Ubuntu system, you have to add the i386 architecture and install the three library packages libc6:i386, libncurses5:i386, and libstdc++6:i386:
x64 extends x86's 8 general-purpose registers to be 64-bit, and adds 8 new 64-bit registers. The 64-bit registers have names beginning with "r". For example, the 64-bit extension of eax is called rax. The new registers are named r8 through r15.
The lower 32 bits, 16 bits, and 8 bits of each register are directly addressable in operands. This includes registers, like esi, whose lower 8 bits weren't previously addressable. The following table specifies the assembly-language names for the lower portions of 64-bit registers.
Operations that output to a 32-bit subregister are automatically zero-extended to the entire 64-bit register. Operations that output to 8-bit or 16-bit subregisters aren't zero-extended (this is compatible x86 behavior).
Instructions that refer to 64-bit registers are automatically performed with 64-bit precision. For example, mov rax, [rbx] moves 8 bytes beginning at rbx into rax.
A special form of the mov instruction has been added for 64-bit immediate constants or constant addresses. For all other instructions, immediate constants or constant addresses are still 32 bits.
For parallel installations of different versions use the compressed .7z archives. Make sure to extract them into an empty folder (we recommend the free software 7-Zip to extract) and create program shortcuts manually if required.

Yes, iTunes (64-bit) still runs on Windows. Apple replaced it in macOS Catalina in 2019, but on Windows it is still supported, including updates and other new features to make it easier for iPhone and iPad devices to interact with Microsoft's operating system.
To transfer files from iPhone to PC with iTunes (64-bit), you have to connect your iPhone via USB to your PC. After that, click on the device icon, and click on Settings to see what kind of content can be synchronized. After selecting it, click on synchronize, and all the items you have synchronized will be copied to the PC.
You can try Debian by booting a live system from a CD, DVD or USB key without installing any files to the computer. You can also run the included Calamares Installer. Only available for 64-bit PC. Read more information about this method.
EnterpriseOne has supported 64-bit hardware, operating systems, databases, Java, and middleware for many years. Components such as HTML Server, Enterprise Server, Development client, AIS Server, Orchestrator and other Java-based components, are 64-bit enabled.
I'm surprised that there is only a 32-bit driver when most people are now using 64-bit. The strange thing is that the Fuji-Xerox driver (fuji-xerox-docuprint-c525-a-ap_1.0-2_i386.deb) that we use for our other phaser (6125) works fine after resetting the tray/paper defaults. Of course it won't work for the 6010 because of the different printer languages used, but it's interesting that such an old driver still works in both 32 and 64-bit environments.
Having worked at Xerox for many years, I understand the focus is with corporate 500 companies, yet the 6010 has a much broader market focus, including home-office and personal use. I'm coming across many more people who are moving away from windows, so I hope that they are able to find the time to produce a 64-bit driver. I for one would volunteer to beta test any release.
