It is not possible to disable all intrinsics on 32-bit ARM, and it's not necessarily desirable to do so for AArch64 (so I don't think it's implemented). Note that this is somewhat true for x86 too - leading to things like DivU64x32 in BaseLib. > How does the linker find the CompilerInstrinsicsLib in linking phase?
