Subject: Don't discard relocs against __ehdr_start
X-Git-Tag: gdb-7.8-release~1616
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=818d220a6fe3d0512a226188e9164245a02c9185;p=platform%2Fupstream%2Fbinutils.git

Don't discard relocs against __ehdr_start

__ehdr_start will be defined by assign_file_positions_for_non_load_sections
later.

	PR ld/16428
	* elf32-i386.c (elf_i386_allocate_dynrelocs): Don't discard relocs
	against __ehdr_start.
	* elf64-x86-64.c (elf_x86_64_allocate_dynrelocs): Likewise.
