| # This shell script produces a header file fragment that defines |
| # SYSROOT_SUFFIX_SPEC. It assumes that the sysroots will have the same |
| # structure and names used by the multilibs. |
| |
| # Invocation: |
| # print-sysroot-suffix.sh \ |
| # MULTILIB_OSDIRNAMES \ |
| # MULTILIB_OPTIONS \ |
| # MULTILIB_MATCHES \ |
| # MULTILIB_REUSE |
| # > t-sysroot-suffix.h |
| |
| # The four options exactly correspond to the variables of the same |
| # names defined in the t-sysroot-suffix tmake_file fragment. |
| |
| # Example: |
| # sh ./gcc/config/print-sysroot-suffix.sh "a=A" "a b/c/d" "" |
| # => |
| # #undef SYSROOT_SUFFIX_SPEC |
| # #define SYSROOT_SUFFIX_SPEC "" \ |
| # "%{a:" \ |
| # "%{b:A/b/;" \ |
| # "c:A/c/;" \ |
| # "d:A/d/;" \ |
| # ":A/};" \ |
| # ":}" |
| |
| # The script uses temporary subscripts in order to permit a recursive |
| # algorithm without the use of functions. |
