For the rest of this book, as I already mentioned, we'll focus solely on Intel syntax when reviewing output from our tools. A quick internet search using your favorite search provider will yield a plethora of results on the differences between the two formats.
You may encounter several different naming conventions for 32-bit and 64-bit Intel assembly. When reading x86, x86-32, x86_32, IA32, and IA-32, know that this refers to 32-bit Intel assembly. x86-64, x86_64, IA64, and IA-64 refer to 64-bit Intel assembly. Intel, in this case, refers to the processor-specific instruction set, not necessarily the syntax format. In this recipe, I'm using an Intel processor, though the first screenshot shows the AT&T formatted syntax.
