Currently, section ordering differs a little for non-loaded reloc sections output by ld -emit-relocs or ld -r and that after passing such objects through objcopy. Not that it really matters, but it would be better for a simple objcopy to produce an unchanged output object file. Also, section headers are put somewhere in the middle of the non-loaded sections, again slightly differently for ld and objcopy. This patch fixes these discrepancies and puts section headers last, which is where gold puts them, and is where bfd_from_remote_memory wrongly assumed they will be found. bfd/ * elf.c (assign_file_positions_except_relocs): Move section header placement to.. (_bfd_elf_assign_file_positions_for_relocs): ..here. Make static. * elf-bfd.h (_bfd_elf_assign_file_positions_for_relocs): Delete. * elflink.c (bfd_elf_final_link): Don't call above function. gas/testsuite/ * gas/arm/got_prel.d: Adjust for changed section header placement. * gas/i386/ilp32/x86-64-size-1.d: Likewise. * gas/i386/ilp32/x86-64-size-3.d: Likewise. * gas/i386/ilp32/x86-64-size-5.d: Likewise. * gas/i386/ilp32/x86-64-unwind.d: Likewise. * gas/i386/size-1.d: Likewise. * gas/i386/size-3.d: Likewise. * gas/i386/x86-64-size-1.d: Likewise. * gas/i386/x86-64-size-3.d: Likewise. * gas/i386/x86-64-size-5.d: Likewise. * gas/i386/x86-64-unwind.d: Likewise. * gas/ia64/alias-ilp32.d: Likewise. * gas/ia64/alias.d: Likewise. * gas/ia64/group-1.d: Likewise. * gas/ia64/group-2.d: Likewise. * gas/ia64/secname-ilp32.d: Likewise. * gas/ia64/secname.d: Likewise. * gas/ia64/unwind-ilp32.d: Likewise. * gas/ia64/unwind.d: Likewise. * gas/mmix/bspec-1.d: Likewise. * gas/mmix/bspec-2.d: Likewise. * gas/mmix/byte-1.d: Likewise. * gas/mmix/loc-1.d: Likewise. * gas/mmix/loc-2.d: Likewise. * gas/mmix/loc-3.d: Likewise. * gas/mmix/loc-4.d: Likewise. * gas/mmix/loc-5.d: Likewise. * gas/tic6x/scomm-directive-4.d: Likewise. ld/testsuite/ * ld-aarch64/emit-relocs-local-addend.d: Adjust for changed section header placement. * ld-aarch64/local-addend-r.d: Likewise. * ld-mmix/bspec1.d: Likewise. * ld-mmix/bspec2.d: Likewise. * ld-mmix/local1.d: Likewise. * ld-mmix/local3.d: Likewise. * ld-mmix/local5.d: Likewise. * ld-mmix/local7.d: Likewise. * ld-mmix/undef-3.d: Likewise. * ld-sh/sh64/crange3-cmpct.rd: Likewise. * ld-sh/sh64/crange3-media.rd: Likewise. * ld-sh/sh64/crangerel1.rd: Likewise. * ld-sh/sh64/crangerel2.rd: Likewise. * ld-tic6x/common.d: Likewise. * ld-tic6x/shlib-1.rd: Likewise. * ld-tic6x/shlib-1b.rd: Likewise. * ld-tic6x/shlib-1r.rd: Likewise. * ld-tic6x/shlib-1rb.rd: Likewise. * ld-tic6x/shlib-app-1.rd: Likewise. * ld-tic6x/shlib-app-1b.rd: Likewise. * ld-tic6x/shlib-app-1r.rd: Likewise. * ld-tic6x/shlib-app-1rb.rd: Likewise. * ld-tic6x/shlib-noindex.rd: Likewise. * ld-tic6x/static-app-1.rd: Likewise. * ld-tic6x/static-app-1b.rd: Likewise. * ld-tic6x/static-app-1r.rd: Likewise. * ld-tic6x/static-app-1rb.rd: Likewise. * ld-x86-64/ilp32-4.d: Likewise. * ld-x86-64/split-by-file-nacl.rd: Likewise. * ld-x86-64/split-by-file.rd: Likewise.
