x86-64 Assembly: Floating Point Registers Basics with YASM (MOVSD, MULSD, CVTSI2SD)

Quick but thorough introduction to floating-point registers in x86-64 assembly using YASM. Learn why XMM0 is special, how to use MOVSD / MULSD / CVTSI2SD, why you must save floats around function calls, and how easy (or sneaky) stack alignment bugs can crash your program. Live coding + real examples converting integers to doubles and multiplying them. Great next step after basic integer assembly tutorials. 00:00 Introduction to Floating Point Registers 00:28 Why Floating Point Uses Special Registers 01:35 Floating Point Return Value in XMM0 02:17 XMM Registers Overview XMM0 to XMM15 02:48 ABI Rules No Callee-Saved XMM Registers 03:16 128-bit XMM Registers Purpose and Size 04:00 Ed Jorgensen x86-64 Textbook Reference 05:03 Locating XMM Documentation in Textbook 05:20 Earthquake - I am going to die 06:24 Chapter 18 Floating Point Instructions 07:34 MOVSS vs MOVSD Single vs Double Precision 09:11 Understanding SS and SD Instruction Suffixes 10:58 MOVSD Example Register to Register 11:03 Conversion Instructions CVT Family 13:02 Floating Point Arithmetic ADDSD MULSD SUBSD 25:48 Program Demo User Input Section 26:01 Converting Integer to Double CVTSI2SD 26:29 Multiplying by Constant Float MULSD 28:56 Saving Result Printing Modified Float 31:38 Multiplying User Integer by User Float 33:54 Final Result Display Program Summary 35:19 Stack Alignment Crash Demonstration 36:24 Conclusion Key Takeaways 36:52 Outro Subscribe and Thanks =-=-=-=-=-=-=-=-= Thanks for watching!
