This +# file is used to create a header file with definitions for the various +# versions. The static linker will encode in the EI_ABIVERSION field in +# the e_ident array in the ELF program header the required ABI version. +# This is not a bitmask. The maximum ABI version required must be +# encoded. +# +# Adding new features should always happen by appending new lines. Never +# add entries in the middle or where they seem "logical". Once a version +# is assigned to a feature it must not change again.

The PLATFORM name can use the wildcards available in +# the Bourne shell's case expression. +# +# Note that the same symbol can be used using different platform triples. +# They don't have to be in the same order relative to other entries. This +# can happen if the feature is implemented for different architectures +# at different times. +# +# This file is parsed by a script which produces a header file containing +# a single enum definition.
