--- Comment #4 from cvs-commit at gcc dot gnu.org <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Alan Modra <amo...@sourceware.org>: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=e1c6cf618cbeebbafd34afc5ee921fcbf7061bfa commit e1c6cf618cbeebbafd34afc5ee921fcbf7061bfa Author: Alan Modra <amo...@gmail.com> Date: Tue Jan 14 20:45:53 2020 +1030 PR25384, PowerPC64 ELFv1 copy relocs against function symbols Function symbols of course don't normally want .dynbss copies but with some old versions of gcc they are needed to copy the function descriptor. This patch restricts the cases where they are useful to compilers using dot-symbols, and enables the warning regardless of whether a PLT entry is emitted in the executable. PLTs in shared libraries are affected by a .dynbss copy in the executable. bfd/ PR 25384 * elf64-ppc.c (ELIMINATE_COPY_RELOCS): Update comment. (ppc64_elf_adjust_dynamic_symbol): Don't allow .dynbss copies of function symbols unless dot symbols are present. Do warn whenever one is created, regardles of whether a PLT entry is also emitted for the function symbol. ld/ * testsuite/ld-powerpc/ambiguousv1b.d: Adjust expected output. * testsuite/ld-powerpc/funref.s: Align func_tab. * testsuite/ld-powerpc/funref2.s: Likewise. * testsuite/ld-powerpc/funv1.s: Add dot symbols. -- You are receiving this mail because: You are on the CC list for the bug.
