[PATCH v2 12/22] libtasn1: disable code not needed in grub |
Date: |
Wed, 30 Jun 2021 18:40:21 +1000 |
We don't expect to be able to write ASN.1, only read it,
so we can disable some code.
Do that with #if 0/#endif, rather than deletion. This means
that the difference between upstream and grub is smaller,
which should make updating libtasn1 easier in the future.
With these exclusions we also avoid the need for minmax.h,
which is convenient because it means we don't have to
import it from gnulib.
