I’ve come across a specific instruction sequence that I need help understanding, particularly the comparison (`cmp`) operation and how to break at this point in GDB on an Intel Core […]
I’m working with x86-64 architecture in long mode and want to know if it’s possible to directly update the Translation Lookaside Buffer (TLB) with a mapping from a virtual address […]
Hello , I’m working on optimizing a bubble sort implementation in `C` for an `x86-64` architecture specifically targeting an Intel Core i7 processor using `GCC 11.2` . I noticed that […]
I am debugging a program on an `x86-64` system `Ubuntu 22.04` `GDB v10.2` `GCC 11.2.0` using `GDB` and encountered an unexpected behavior. I was inspecting the value of the `rbx` […]
I am working on a text based tic-tac-toe game for some users, using x86 assembly on an Intel Core i7 12700K systems running Ubuntu 22.04. I’m using NASM assembler and […]
