Leif,
I didn’t realized tool supports a global NULL library class usage. I now found this https://bugzilla.tianocore.org/show_bug.cgi?id=645.
Thanks for the education😊
Thanks,
Ray

Hi Ray,

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.

For example:
https://github.com/tianocore/edk2/blob/master/MdeModulePkg/MdeModulePkg.dsc#L172
Regards,
Leif
