I found this line in code generated by the MSVC compiler from Visual Studio 2008, while trying to figure out what seems to be a compiler bug:
I\'m learning to program the ATA bus. In Bochs it seems my code for r/w works, however I can\'t say that for sure until I try it with开发者_StackOverflow社区 real disk. Thus I need to find out how to
Unlike (most) RISC arch, x86 instructions have variable length. The start/end of an instruction doesn\'t have to aligned. If the compiler doesn\'t one instruction could be just lying across the page m

I have a C program that runs on bare x86 (without an OS) in protected mode. I need to delay the program\'s execution for a certain amount of time. Currently, I\'m doing this:
I want to know some basic concepts of assembly language to understand it\'s architecture in a better way. I have learnt high level languages like C# .NET, Ja开发者_JS百科va, and have also been introdu
Is it possible to use SSE for bit manipulations on data that is not byte-aligned?For example, I would like to do implement this using SSE:
