X8664 NASM Assembly Quick Reference ('Cheat Sheet') Here's the full list of ordinary integer x86 registers. The 64 bit registers are shown in red. The cheat sheet is intended for 32-bit Windows programming with FASM. One A4 page contains almost all general-purpose x86 instructions (except FPU, MMX and SSE instructions). Note: NASM, the Netwide Assembler, is a 80 x86 and x86-64 platform based on the assembly language compiler, designed to achieve the compiler program cross-platform and modular features. Nasm -f bin -o payload.bin payload.asm nasm -f elf payload.asm; ld -o payload payload.o; objdump -d payload.
