  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.
  27
  28 # Invocation:
  29 #   print-sysroot-suffix.sh \
  30 #          MULTILIB_OSDIRNAMES \
  31 #          MULTILIB_OPTIONS \
  32 #          MULTILIB_MATCHES \
  33 #      > t-sysroot-suffix.h
  34
  35 # The three options exactly correspond to the variables of the same
  36 # names defined in the tmake_file fragments.
  37
  38 # Example:
  39 #   sh ./gcc/config/print-sysroot-suffix.sh "a=A" "a b/c/d" ""
  40 # =>
  41 #   #undef SYSROOT_SUFFIX_SPEC
  42 #   #define SYSROOT_SUFFIX_SPEC "" \
  43 #   "%{a:" \
  44 #     "%{b:A/b/;" \
  45 #     "c:A/c/;" \
  46 #     "d:A/d/;" \
  47 #     ":A/};" \
  48 #   ":}"
  49
  50 # The script uses temporary subscripts in order to permit a recursive
  51 # algorithm without the use of functions.
