# This script takes the following arguments:
20
#
21
#    - the target sysroot
22
#    - the value of $(MULTILIB_MATCHES)
23
#    - the value of $(MULTILIB_OPTIONS)

#
25
# It uses these arguments to construct a definition of SYSROOT_SUFFIX_SPEC,
26
# which it prints to the standard output.  For each multilib directory FOO,
27
# the script checks whether $sysroot has a subdirectory FOO, and if so will
28
# use /FOO for all compatible command-line options.  It will not add a
29
# suffix for /FOO's options otherwise.  These suffixes are concatenated,
30
# with one subspec for each space-separated entry in $(MULTILIB_OPTIONS).
