2017-11-01PR22374, PowerPC unnecessary PLT entriesAlan Modra2-5/+4
We don't need a PLT entry when function pointer initialization in a read/write section is the only reference to a given function symbol. This patch prevents the unnecessary PLT entry, and ensures no dynamic relocs are emitted when UNDEFWEAK_NO_DYNAMIC_RELOC says so. bfd/ PR 22374 * elf32-ppc.c (ppc_elf_adjust_dynamic_symbol): Don't create a plt entry when just a dynamic reloc can serve. Ensure no dynamic relocations when UNDEFWEAK_NO_DYNAMIC_RELOC by setting non_got_ref. Expand and move the non_got_ref comment. * elf64-ppc.c (ppc64_elf_adjust_dynamic_symbol): Likewise. ld/ * testsuite/ld-powerpc/ambiguousv2.d: Remove FIXME.
2017-11-01PR22374 testcase, function pointer references in .dataAlan Modra6-0/+39
Function pointer references in .data ought to use a dynamic reloc. There shouldn't be any need for a PLT entry and definitely no copy reloc. This test fails on quite a few targets, but isn't something that anyone should worry about too much. It's really just a missed optimization.

2017-10-24[BFD][PR21703]Override the new defined symbol with the old normal symbol ↵Renlin Li10-0/+92
when --allow-multiple-definition is provided. The behavior of _bfd_elf_merge_symbol and _bfd_generic_link_add_one_symbol is inconsistent. In multiple definition case, _bfd_elf_merge_symbol decided to override the old symbol definition with the new defintion, (size, type, target data) In _bfd_generic_link_add_one_symbol, it simply return without doing anything because of allow-multiple-definition is provided. This leaves the symbol in a wrong state. Here, following the documentation, I made this patch to force the old definition override the new definition if the old symbol is not dynamic or weak. Because, in those two cases, it's expected to do some merge. I have checked that, those two cases are properly handled. bfd/ PR ld/21703 * elflink.c (_bfd_elf_merge_symbol): Handle multiple definition case. ld/ PR ld/21703 * testsuite/ld-elf/elf.exp: Run new tests. * testsuite/ld-elf/pr21703-1.s: New. * testsuite/ld-elf/pr21703-2.s: New. * testsuite/ld-elf/pr21703-3.s: New. * testsuite/ld-elf/pr21703-4.s: New. * testsuite/ld-elf/pr21703-r.sd: New. * testsuite/ld-elf/pr21703-shared.sd: New. * testsuite/ld-elf/pr21703.sd: New. * testsuite/ld-elf/pr21703.ver: New.

2017-10-19RISC-V: Add R_RISCV_DELETE, which marks bytes for deletionPalmer Dabbelt2-1/+6
We currently delete bytes by shifting an entire BFD backwards to overwrite the bytes we no longer need. The result is that relaxing a BFD is quadratic time. This patch adds an additional relocation that specifies a byte range that will be deleted from the final object file, and adds a relaxation pass (between the existing passes that delete bytes and the alignment pass) that actually deletes the bytes. Note that deletion is still quadratic time, and nothing uses R_RISCV_DELETE yet. I've been meaning to go convert all the other relaxations to use R_RISCV_DELETE and then make it faster, but this patch has been sitting around for months so it looks like that won't happen for a bit. The PCREL->GPREL relaxation that comes next uses this, and since we've been using these two patches out of tree since I wrote them months ago I figure it's better to just get them in now. I (or someone else :)) can convert all the relocations later... R_RISCV_DELETE will never be emitted into ELF objects, so therefor isn't exposed to the rest of binutils. As such, we're not considering this as part of the ABI. bfd/ChangeLog 2017-10-19 Palmer Dabbelt <palmer@dabbelt.com> * elfnn-riscv (R_RISCV_DELETE): New define.

2017-10-16ELF: Call check_relocs after opening all inputsH.J. Lu55-130/+194
For all ELF targers, call check_relocs after opening all inputs and garbage collection. Since the symbol resolution is known, check_relocs can be simplified. Also garbage collection doesn't need to undo what check_relocs has done for symbols which have been garbage collected. Since ELF targets never see the removed sections, gc_sweep_hook can be removed from elf_backend_data and we can avoid GOT/PLT with garbage collection now. Set link_info.check_relocs_after_open_input to TRUE for all linker targets which use ELF linker and update garbage collection tests to remove unused GOT section. ldemul_after_check_relocs is added for powerpc to support --secure-plt, --bss-plt and --sdata-got. Tested natively without regressions on i686, x86-64 and x32.

2017-10-12Set dynamic_undefined_weak to zero for static PIEsAlan Modra2-0/+14
I believe we should be warning if ld is given both --no-dynamic-linker and -z dynamic-undefined-weak. The two options are contradictory, the first says an executable has no dynamic interpreter to resolve dynamic symbols, while the second is asking for dynamic symbols to be emitted. (And even if a static PIE's relocation code, which is needed to process R_*_RELATIVE relocs, could process symbols, there are no DT_NEEDED dynamic objects to define such symbols.) I also think that dynamic_undefined_weak is the right flag to control whether undefined weaks are made dynamic, whether in static PIEs or anywhere else. So force it to 0 for static PIEs, fixing PR 22269 for powerpc and any other target where the backend usually defaults to undefined weaks being made dynamic. This patch introduces regressions. I'd normally not do that, but these are all in very recently added test cases, or expose bugs in the x86 backend. The test cases were added after I'd made it known that this patch or one like it was imminent. PR 22269 * emultempl/elf32.em (after_parse): Warn on --no-dynamic-linker -z dynamic-undefined-weak combination. Set dynamic_undefined_weak to zero when nointerp.

2017-10-11Add 2 testcases for PR ld/22269H.J. Lu4-0/+40
Since undefined weak symbols in static PIE are always resolved to 0 at run-time, linker should resolve them as 0 at link-time, regardless of whether "-z dynamic-undefined-weak" is used. "-z dynamic-undefined-weak" only makes undefined weak symbols dynamic, but doesn't change undefined weak symbol resolution in static PIE at link-time. These tests currently pass on x86, but fails on many other targets. The framework to resolve weak symbols in static PE at link-time is posted at https://sourceware.org/ml/binutils/2017-10/msg00087.html which requires users/hjl/check_relocs branch to call check_relocs after opening all inputs.

2017-10-05PR21167, relocation sections not included in groupsAlan Modra2-4/+10
This fixes a wart I've known about for years, but haven't done anything about because BFD treats relocation sections as an adjunct to the section they relocate. SHF_GROUP on the section thus implicitly applies to its relocation section(s), but it is an error that the reloc sections aren't part of the group. Like many patches to gas, this wasn't as straightforward as it could be due to a number of backends, i386, cr16 and others, removing relocs in tc_get_reloc rather than marking them as "done" earlier in md_apply_reloc. So it isn't possible for the group support to reliably detect the presence of relocs by looking at fixups earlier than write_relocs. However the group support needs to create signature symbols, and that must be done before the symbol table is frozen, before write_relocs. So split off the group sizing from elf_adjust_symtab and put it in elf_frob_file_after_relocs. bfd/ PR 21167 * elf.c (_bfd_elf_setup_sections): Don't trim reloc sections from groups.

I am applying a patch that has been lying around in the Fedora binutils sources for a while. It skips the PR14918 linker test for ARM based targets. This test checks that libgcc is not included in a link of an empty executable. This works for most targets, but on the ARM the crt1.o startup code calls __libc_csu_init which is in /usr/lib/libc_nonshared.a(elf-init.oS). This in turn needs __aeabi_unwind_cpp_pr0@@GCC_3.5 which is provided by libgcc_s.so.1, and so the test fails.
