The sem_* functions bring in references to tdelete, tfind, tsearch and twalk. But the t* functions are XSI-shaded, while sem_* aren't. This patch fixes this by using __t* instead, exporting those functions from libc at version GLIBC_PRIVATE (since sem_* are in libpthread) and using libc_hidden_* for the benefit of calls within libc. Tested for x86_64 and x86 (testsuite, and comparison of disassembly of installed stripped shared libraries). libpthread gets changes from PLT reordering; addresses in libc change because of PLT / dynamic symbol table changes. [BZ #18536] * misc/tsearch.c (__tsearch): Use libc_hidden_def. (__tfind): Likewise. (__tdelete): Likewise. (__twalk): Likewise. * misc/Versions (libc): Add __tdelete, __tfind, __tsearch and __twalk to GLIBC_PRIVATE. * include/search.h (__tsearch): Use libc_hidden_proto. (__tfind): Likewise. (__tdelete): Likewise. (__twalk): Likewise. * nptl/sem_close.c (sem_close): Call __twalk instead of twalk. Call __tdelete instead of tdelete. * nptl/sem_open.c (check_add_mapping): Call __tfind instead of tfind. Call __tsearch instead of tsearch. * sysdeps/sparc/sparc32/sem_open.c (check_add_mapping): Likewise. * conform/Makefile (test-xfail-POSIX/semaphore.h/linknamespace): Remove variable. (test-xfail-POSIX2008/semaphore.h/linknamespace): Likewise.
