Summary
This episode explores how integer literals are handled in ARM assembly compared to x86-64. Jason demonstrates that while Intel processors can directly represent 32-bit values in instructions, ARM has stricter limitations due to its fixed 32-bit instruction size. He explains ARM's encoding technique which uses an 8-bit immediate value combined with a 4-bit rotate field to represent larger numbers. Using compiler outputs from both GCC and Clang, he reveals how ARM represents values larger than 255 through either memory loading (GCC) or bit manipulation through rotation (Clang).
