Differences in SIMD Instructions and Targeting Specific Architectures

This chapter explores the variations in SIMD instructions between ARM and X64 architectures, highlighting the distinctions and overlapping instructions. It delves into how the raw compiler's configurations for ARM and X64 target different SIMD instructions, emphasizes the importance of specifying the target architecture when compiling SIMD code, and acknowledges the evolution of different SIMD instruction set versions over time.
