What's the difference between x64 and x32 debugging?


Asked by Nalani Vasquez on Dec 02, 2021 FAQ



x64dbg can debug both x64 and x32 applications. There is only one interface. x64dbg uses Qt, TitanEngine, Zydis, Yara, Scylla, Jansson, lz4, XEDParse, asmjit and snowman. x64dbg uses C++ and Qt to quickly add new features. x64dbg has an integrated, debuggable, ASM-like scripting language.
Next,
If your host computer is running a 32-bit version of Windows, use the 32-bit debugging tools. (This situation applies to both x86-based and x64-based targets.) If your host computer uses an x64-based processor and is running a 64-bit version of Windows, the following rules apply:
Consequently, Now, term x86 refers to a 32 bit CPU and operating system for 32-bit processors (80386 and 80486), while term x64 refers to 64 bit CPU and operating system for 64-bit processors. So, what is the major difference between 32 and 64 bit? Let’s keep reading the following section “x86 vs x64” to get the answer.
Also,
An open-source x64/x32 debugger for windows. Check out the blog! A familiar, yet new interface. Fully customizable color schemes. More information about jump targets and register values. Smart, content-sensitive register view. IDA-like instruction token highlighter (highlight registers, etc.)
Likewise,
If you are debugging live user-mode code that is running on the same computer as the debugger, use the 64-bit tools for debugging 64-bit code and 32-bit code running on WOW64. To set the debugger for 32-bit or 64-bit mode, use the .effmach command.
