# $FreeBSD$

# Setup variables for the linker.
#
# LINKER_TYPE is the major type of linker. Currently binutils and lld support
# automatic detection.
#
# LINKER_VERSION is a numeric constant equal to:
#     major * 10000 + minor * 100 + tiny
# It too can be overridden on the command line.
#
# LINKER_FEATURES may contain one or more of the following, based on
# linker support for that feature:
#
# - build-id:  support for generating a Build-ID note
# - retpoline: support for generating PLT with retpoline speculative
#              execution vulnerability mitigation
#
# LINKER_FREEBSD_VERSION is the linker's internal source version.
#
# These variables with an X_ prefix will also be provided if XLD is set.
#
# This file may be included multiple times, but only has effect the first time.
