Sep 15, 2023 · This chapter covers ARMv8 architecture and programming. Compiler Options Now that we have a high level understanding of ARM floating-point technologies, let’s take a look at the compiler options we can use. Below is a comprehensive overview of: General-Purpose Registers Condition Flags (NZCV) Instruction Encoding with Hexadecimal Examples AI/ML Instruction Extensions (NEON, SVE) Quick Links Account Products Tools and Software Support Cases Manage Your Account Profile and Settings Oct 25, 2024 · My question is, however, is SP architecturally mapped to the appropriate SP_ELx register or is SP_ELx copied into SP on an EL change? In other words, if say I write to SP, do I also write to SP_ELx? I attempted to read the manual on this, but it seemed fairly ambiguous and could have been interpreted either way.
