Subject: Only give FDE encoding warnings if --eh-frame-hdr was specified.
X-Git-Url: http://git.efficios.com/?a=commitdiff_plain;ds=sidebyside;h=bce7c9d6fbba85c351ee343843dc9adc285e44a3;p=deliverable%2Fbinutils-gdb.git

Only give FDE encoding warnings if --eh-frame-hdr was specified.

This bug was observed on nios2-linux-gnu with some C++ programs
linked with -pie or -shared.  The nios2 ABI doesn't include appropriate
relocations in this instance and GCC is also being patched not to pass
--eh-frame-hdr to the linker in those cases.

        * elf-eh-frame.c (_bfd_elf_discard_section_eh_frame): Make
        FDE encoding warning conditional.
