4 # and MULTILIB_REUSE.

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