32bit-64bit

X32 allows one to write programs using 32-bit integers, longs and pointers that run on x86_64 processors. Using X32 has a number of benefits under certain use cases. (X32 is different than X86 or X64; see Difference between x86, x32, and x64 architectures for more details). It appears some Windows Enterprise Server supports X32, but I'm having trouble finding more information on it. That's based on some Intel PDFs, like Intel® Xeon® Processor E5-2400 Series-based Platforms for Intelligent Systems : Microsoft's documentation on Predefined Macros lists the usual suspect, like _M_X64 and _M_AMD64

Considering the following: We have a 32 bit Datasnap server installed on a 64 BIT Windows Server In embarcadero\rad studio\11.00\redist are 2 folders : 32 bit and 64 bit, with in each a midas.dll. Wich file should we put where? In windows\system32 or windows\syswow64 ? Never put anything in the Windows system directories (unless you have a very, very, very good reason to write there). It's a very bad practice (dating back to Windows 3.x times and poor developers skills, because those dirs are always in the search path) just leading to troubles (i.e. if another application chnages your DLL with

I am calculating the average of sixteen 64 bit numbers added together and I think that I have done all the addition correctly, but now I need to figure out how to divide a 64 bit number by 16 and I am stuck! Any help would be great thank you so much. Here is my code so far. tableSize EQU 16 sum EQU 0x40000000 average EQU 0x40000008 MOV r8, #14 ADR r0, table LDR r9, =sum LDR r10,=average LDR r1, [r0], #1 ;hi #1 LDR r2, [r0], #1 ;lo #1 SUM SUB r8, r8, #1 LDR r3, [r0], #1 ;hi #2 LDR r4, [r0], #1 ;lo #2 ADDS r5, r2, r4 ;lo 1 + lo 2 set flags ADC r6, r1, r3 ;hi 1 + hi 2 + carry MOV r1, r6 MOV r2,

I have a 32-bit binary-only C .so (provided by a vendor) built for Linux (using gcc), that I need to link to a 64-bit C/C++ application (which I am developing). Is there any way to access this library from my application? I know there will need to be care taken to handle arguments and pointers to functions inside the .so, and I know that long ago it was deemed basically impossible (like this post). I'm hoping the situation has changed. It might be possible to hack together some assembler glue code to translate the function parameters and return values from one module to the other, and flip the

[Update] I've since compiled successfully and anyone else chasing these binaries can download from here I'm compiling version 2.06 of lzo by issuing the following command from the Visual Studio Command Prompt (2010) b\win64\vc_dll.bat which produces lzo2.dll without any errors, however this doesnt look like it really did produce the 64-bit dll as my 32bit C# app can still reference and call methods (successfully) How can I compile the 64bit version? some of the comments on this question may be outdated as the question changed but I since changed it back to the original question when it got

I'm getting conflicting reports from various places. Engadget's review says InputManager plug-ins being completely ignored (and causing strange behaviour if the application is loaded in 32-bit mode), but this mailing list thread says they will work if the 32/64-bit compatibility is right. So I have two questions: Do we get to use InputManagers in Snow Leopard? If yes, will it work the same way as in Leopard. And if no, what is good a workaround (because 1Password is apparently working on a fix)? If you really need to inject code into applications to accomplish what you're trying to do, use

I'm a beginner programmer in my first year of Computer Science. I'm curious about the 32 bit and 64 bit systems, and how it affects developing software. When I download software I need to choose between the two, while other software only has a 32 bit version. Are there different ways of programming for a 64 bit system? Is it compiled in the same way? What are the main benefits of a separate 64 bit app? Cheers Generally speaking the main benefit of 64 bit application is that it has access to more memory. Having 32 bit pointer you can access only 4GB of memory. Most modern compilers have option
