I\'m implementing the backend for a JavaScript JIT compiler that produces x86 code. Sometimes, as the result of bugs, I get segmentat开发者_JAVA百科ion faults. It can be quite difficult to trace back
I am wondering if it is possible for a Windows program to allocate a segment descriptor within the process\' local descriptor table. Is there a Windows API function that can 开发者_开发问答install a n

I have a very simple program to multiply four numbers. It works fine when each of them is 10000 but does not if I change them to 10001. The result
As part of a compiler project I have to write GNU assembler code for x86 to compare floating point values. I have tried to find resources on how to do this online and from what I understand it works l
I\'ve found that mov al, bl mov ah, bh is much faster than mov ax, bx Can anyone explain me why? I\'m running on Core 2 Duo 3 Ghz, in 32-bit mode under Windows XP.
Im trying to w开发者_开发技巧rite a bootloader for a Hobby OS and have it working great. Nothing Special, just prints a line of text:
One of projects in our solution references a third party .NET C++ assembly which exists as 64 and 32 bit version. As we wanna provide our application for 32 & 64 bit systems we currently start two
Edit: My original example had a silly mistake. After fixing it I still get weird results, though. In my naive attempt to measure my CPU speed the \"brute-force\" way, I made the program below:
OK, I\'m new to PC Assembler. I\"m trying to write an program, but it won\'t stop looping. I\'m guessing the ECX register is being modified? How can I fix this? Thanks.
