# This shell script produces a header file fragment that defines
24
# SYSROOT_SUFFIX_SPEC.  It assumes that the sysroots will have the same
25
# structure and names used by the multilibs.
26
 
27
# Invocation:
28
#   print-sysroot-suffix.sh \
29
#          MULTILIB_OSDIRNAMES \
30
#          MULTILIB_OPTIONS \
31
#          MULTILIB_MATCHES \
32
#      > t-sysroot-suffix.h
33
 
34
# The three options exactly correspond to the variables of the same
35
# names defined in the tmake_file fragments.
36
 
37
# Example:
38
#   sh ./gcc/config/print-sysroot-suffix.sh "a=A" "a b/c/d" ""
39
# =>
40
#   #undef SYSROOT_SUFFIX_SPEC
41
#   #define SYSROOT_SUFFIX_SPEC "" \
42
#   "%{a:" \
43
#     "%{b:A/b/;" \
44
#     "c:A/c/;" \
45
#     "d:A/d/;" \
46
#     ":A/};" \
47
#   ":}"
48
 
49
# The script uses temporary subscripts in order to permit a recursive
50
# algorithm without the use of functions.
