23 # 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.
