Subject: 	* elf-bfd.h (struct eh_cie_fde): Add need_relative and
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8935b81f1f49a0a8db4674b70a4b5d46ecd00b28;p=binutils-gdb.git

	* elf-bfd.h (struct eh_cie_fde): Add need_relative and
	need_lsda_relative.
	* elf-eh-frame.c (_bfd_elf_eh_frame_section_offset): Set
	need_relative or need_lsda_relative if we are processing an
	offset for a reloc on a FDE initial loc or LSDA field
	respectively.
	(_bfd_elf_write_section_eh_frame): Test need_relative and
	need_lsda_relative in place of corresponding make_* field
	when deciding to use pc-relative encodings.
