64-bit

问题 I currently have a 32-bit .Net application (on x86 Windows) which require lots of memory. Recently it started throwing System.OutOfMemoryException's. So, I am planning to move it to a x64 platform as 64-bit process. So will this help with the out of memory exceptions. I was reading this article from MSDN Memory limits for Windows So, my question is if I compile a 64bit .Net application, will it have IMAGE_FILE_LARGE_ADDRESS_AWARE set as default (As the article suggests)? i.e will I be able to

问题 I'm not a hardware guy, but I know that Visual Studio in a 64 bit version issue request was declined by Microsoft stating that a 64 bit version would not have good performance. Two noticeable differences between the two that I feel are obvious is the code base. One began it's life in 1997, one would think that means more baggage on the Visual Studio side, less opportunities to have very modern application architecture and code and that may make it harder and possibly stuff may be built to

问题 All WoW64 apps go through WoW64 emulation layer. I'd like to know what happen in this layer.(especially, how they can convert address space) Please give me some important points. 回答1: Since you have already posted the diagram it is clear that you know why WOW64 exists. Now to answer your question: I'd like to know what happen in this layer. I think you want to know how it is implemented. Process startup: The loader loads 64-bit user-mode part 'Ntdll.dll' as usual, but also loads 32-bit Ntdll

问题 This question already has an answer here : Mach-O 64-bit format does not support 32-bit absolute addresses. NASM Accessing Array (1 answer) Closed last year . %include "along64.inc" default rel section .data EnterMsg : db "Enter a number to add to the list; enter 0 when you done" ,0ah,0 ExitMsg : db "The sorted list: " ,0ah,0 InputError1 : db "Input Error; Integers Only" ,0ah,0 InputError2 : db "Input Error; Maximum list is 100" ,0ah,0 InputError3 : db "Input Error; Enter AT LEAST ONE Int"

问题 And, if it is possible, can you please point me to an example of this? Thanks! 回答1: What you are looking for is cross compilation. http://en.wikipedia.org/wiki/Cross_compiler#GCC_and_cross_compilation As Tomas said, you need the libs of the target machine installed and assuming you are using gcc you will need to use the "-b machine" option, and probably a few other options also (man gcc, and spend a lot of time reading!). This can be a real pain to get right, so i would ask whether it is

问题 I can't figure out why this code isn't working for me. I need to use scanf function for double and then printf for same double. When using this code results are not good. What I see are pretty random characters. .data d1: .double format: .asciz "%lf\n" format2: .asciz "%lf" .text .globl main main: subq $8, %rsp #scanf movq $0, %rax movq $d1, %rsi movq $format2, %rdi call scanf addq $16, %rsp #printf movq $1, %rax movsd d1, %xmm0 movq $format, %rdi call printf addq $16, %rsp #exit movq $1,

问题 I'm getting the following error when trying to compile OpenSSL 1.0, 64 bit: ias -o tmp32\ia64cpuid.obj tmp32\ia64cpuid.asm 'ias' is not recognized as an internal or external command, operable program or batch file. NMAKE : fatal error U1077: 'ias' : return code '0x1' Stop. Does someone know what can I do? (I do it on Windows 2008 x64 OS) Thanks. 回答1: You've probably chosen VC-WIN64I (as an argument for the perl Configure command), which is a wrong platform in your case. You should have passed

问题 I'm trying to debug some VBScript and normally I'd install the ancient (but free) Microsoft Script Debugger which would work fine on 32-bit XP and 32-bit Windows 7. However after installing it on 64-bit Windows 7 neither //d or //x (or even both) actually invoke the debugger any more. The script will happily run as if I've never supplied the option - but that isn't very useful. Is there anything I can do to get it working? I only use it occasionally to scratch my own itches, so I cannot
