Disable shared version of libtetheringflags
- since the flags are readonly there is no real content to this,
and it should be statically linked for compile/link time optimization
(which should basically optimize the entire library out)
Use C++ magic to compile time verify the macro and flag are in sync.
The way this works:
constexpr auto useLibBpf = COM_ANDROID_TETHERING_READONLY_FLAGS_USE_LIBBPF;
^ this basically requires the macro to resolve to true/false, so that 'auto' resolves to 'const bool'
static_assert(std::is_same<decltype(useLibBpf), const bool>::value, "useLibBpf must be a boolean.");
^ which we check here
static_assert(useLibBpf == com::android::tethering::readonly:🎏:use_libbpf(), "useLibBpf flag mismatch");
^ and this then requires the macro and flag to be identical *and* compile time known
Test: TreeHugger
Flag: EXEMPT PURE_REFACTOR
