GCC 5 will generate a relocation for protected symbol: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65248 when compiling for a shared library. It is undefined to access protected symbol in IFUNC selector function inside a shared library. PR gold/18628 * testsuite/ifuncdep2.c (global): Change protected to hidden. * testsuite/ifuncmod1.c (global): Likewise. * testsuite/ifuncmod5.c (global): Likewise.
