# MicroBlaze versions are defined as features, the features are setup to
# conflict with other versions as well as unavailable features for particular
# versions.
#
# Versions before v9.0 of MicroBlaze use a versioning scheme of "vX.YY.Z"
# (where Z = [abc]). For v8.* versions of MicroBlaze the revision (Z) changes
# did not affect ABI and are ignored by this tune configuration. Though this
# format is expected by GCC including the revision, but this is defaulted to
# ".a".
#
# Since v9.0 of MicroBlaze the revision (Z) part of versions was entirely
# dropped and the version scheme was changed to "vX.Y".
