I was lucky enough to review a draft of this amazing book. Two of my favorite poems: ; 0x1 .loop: xadd rax,rdx loop .loop ; 0x13 mov rcx,0x40 .loop: mov rdx,rax xor rax,rbx and rbx,rdx shl rbx,0x1 loop .loop From the book's description on https://www.createspace.com/5067642 https://www.createspace.com/5067642: xchg rax, rax Authored by xorpd About the author: "Performs a bitwise logical exclusive-OR of the two packed double-precision floating-point values from the source operand (second operand) and the destination operand (first operand), and stores the result in the destination operand. The source operand can be an XMM register or a 128-bit memory location. The destination operand is an XMM register." (Intel(r) 64 and IA-32 Architectures Software Developer's Manual) ; 0x40 assembly riddles "xchg rax,rax" is a collection of assembly gems and riddles I found over many years of reversing and writing assembly code. The book contains 0x40 short assembly snippets, each built to teach you one concept about assembly, math or life in general. Be warned - This book is not for beginners. It doesn't contain anything besides assembly code, and therefore some x86_64 assembly knowledge is required.
