# Definition of features which introduce new libc ABI versions.  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.  Since some features

# are conditionally added this can only ever be done securely without much

# risk is by adding at the end.

#

# The following lines have one of two formats:

#

#	SYMBOL

# With just a symbol on the line this is the name of a feature which

# is architecture independent.

#

#	SYMBOL	PLATFORM

# Using this form architecture (and platform) dependent features can be

# specified.  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.  An extra symbol is added as entry zero to

# specify the default ABI with number 0 and an artificial last entry is

# added to allow computing the maximum ABI version for the platform.

#

# Feature Name	Configuration

# ------------	-------------

#

# Unique symbol definitions for C++.

# Architecture independent, all ELF targets (== all targets)

UNIQUE

#

# Indirect PLT relocations.  Architecture dependent.
