Date: Thu Jul 27 18:12:07 2023 -0700 bpf: Handle sign-extenstin ctx member accesses Currently, if user accesses a ctx member with signed types, the compiler will generate an unsigned load followed by necessary left and right shifts. With the introduction of sign-extension load, compiler may just emit a ldsx insn instead. Let us do a final movsx sign extension to the final unsigned ctx load result to satisfy original sign extension requirement.
