Vote count: 0 i know the title i gave this question doesn't fit convention but i've only been writing NASM for my 32bit Ubuntu machine for a couple of hours. Below i have included the code that doesn't work, it is supposed to loop incrementing ecx and then checking if it is equal or more than 10, if it is the it should print out 10. I am completely new to actually writing assembly code and have only studied miniscule MASM32 and whats included in the GCSE computer science course. I am eager to lea and hoping that someone with some spare time is able to explain what im doing wrong constructively so that i may progress.

Vote count: 0 I've written some code (main in c, subprogram in assembly x86) to calculate the binomial coefficient recursively and print out all the binomial coefficients with n=10, restricted by m<=n. My problem is that I'm getting a segfault on compile. Segmentation fault (core dumped) Here's the main program: #include <stdio.h> unsigned int result,m,n,i; unsigned int binom(int,int); int main(){ n=10; for (i=0; i<n+1;i++){ printf("i=%d | %d n", i, binom(n,i) ); } retu; } And the recursive sub program: .text .globl binom binom: mov $0x00, %edx #for difference calculation cmp %edi, %esi #m=n? je equalorzero #jump to equalorzero for retuing of value 1 cmp $0x00, %esi #m=0? je equalorzero cmp $0x01, %esi #m=1? mov %esi,%edx sub %edi, %edx cmp $0x01, %edx # n-m = 1 ? je oneoronedifference jmp otherwise equalorzero: add $1, %eax #retu 1 ret oneoronedifference: add %edi, %eax #retu n ret otherwise: sub $1, %edi #binom(n-1,m) call binom sub $1, %esi #binom(n-1,m-1) call binom asked 36 secs agoEgyptian_Coder This entry passed through the Full-Text RSS service - if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.Recommended article from FiveFilters.org: Most Labour MPs in the UK Are Revolting., ...ادامه مطلب

Vote count: 0 I have a native COM dll that I want to build a C# interop assembly for. I'm attempting to do this using tlbimp.exe to generate the c# assembly, and I then regasm.exe to register the assembly for transparent use via COM in another program. I'm delay signing since I'm still in a development environment and wish to do some debugging still. The TlbImp.exe command seems to work fine, the interop file is generated. c:>tlbimp MyNativeComDll.dll /out:MyInteropDll.dll /publickey:myPublicKey.snk /asmversion:1.6.0.0 /delaysign TlbImp : Type library imported to C:MyInteropDll.dll Microsoft .NET Framework Assembly Registration Utility version 4.6.1055.0 for Microsoft .NET Framework version 4.6.1055.0 Copyright (C) Microsoft Corporation. All rights reserved. Unfortunately, its the regasm call that results in an error that I have no idea how to fix. C:>regasm C:MyInteropDll.dll RegAsm : error RA0000 : Could not load file or assembly 'MyInteropDll.dll, Version=1.6.0.0, Culture=neutral, PublicKeyToken=****************' or one of its dependencies. Strong name validation failed. (Exception from HRESULT: 0x8013141A) The system I am build this all on is a x64 windows machine running Windows 7sp1. The MyNativeComDll.dll is a x86 library. All this is being done in a vcxproj post build command, the project being the one that builds the MyNativeComDll.dll. I use MSBuild from the command line to build the solution. I have both Visual Studio 2010, and Visual Studio 2015 installed, and the build fails when running the regasm command whether or not I am using VS2010's Win64 or Regular Developers command prompt. Similarly it fails in much the same fashion when using the VS2015 x64 Native Tools command prompt, or the Developer Command Prompt for VS2015. The command I use to build the solution that contains the project causing the problem is: C:>msbuild MySolution.sln /p:Configuration=Release /v:n /t:Rebuild /p:Platform="Mixed Platforms" The solution contains, ...ادامه مطلب

Vote count: 0 I'm writing a little machine code generator for assembly. I have a question regarding immediate to memory instructions: Let's take these 3 scenarios: "add [ebx+04], 0x1" "add [ebx+04], 0x4040" "add [ebx+04], 0x401000" What I do is going by the immediate constant, I check what is the smallest number of bytes it can fit in then I assume whether its byte ptr, word ptr, dword ptr First one can fit in 1 byte so I assume it to be: "add byte ptr [ebx+04], 0x1" Second can fit in 2 bytes so I assume it to be: "add word ptr [ebx+04], 0x4040" third fits in 4 bytes so I assume it to be: "add dword ptr [ebx+04], 0x401000" Is this correct? asked 54 secs agoBudskii Let's block ads! بخوانید, ...ادامه مطلب

Vote count: 0 I am using the Intel Compiler (icc) on Windows. I let the compiler print the line information of the instructions. Normally the line number matches the source file I passed to the compiler. In some cases it adds instructions generated by some header files I included. But which file is it? mov rax, 0d4b249ad2594c37dH #45.20 which file is ment here? mulsd xmm0, xmm0 #7.3 matches the expected source file MSVC on the other hand print out the filename of the header where this instruction comes from.

Vote count: 0 I have an instruction set that I am told to reorder the instructions to optimize the pipeline and draw the diagram of its execution. This is using a five-stage pipeline style (Fetch, Decode, Execute, Memory, Write Back). So the diagram would look something like this: 1 2 3 4 5 6 7 8 I0 F D E M W I1 F D E M W I2 F D E M W ... etc Below is an image of the instruction set. I drew in where I think some RAW dependencies are. We are using static branch prediction with a not-taken assumption. Since we are dealing with static branch, is it correct to move the Subtract R2, R2, #1 instruction right after the conditional? This way, it is in the branch delay slot and will always be executed no matter what. Is moving that Subtract instruction the only thing I can do? I can't really move or reorder the other instructions because of the data dependencies, can I? Any help would be appreciated.
