2016-05-26MIPS/BFD: Don't stop processing on `bfd_reloc_outofrange'Maciej W. Rozycki31-193/+65
Upon a `bfd_reloc_outofrange' error continue processing so that any further issues are also reported, similarly to how `bfd_reloc_overflow' is handled. Adjust message formatting accordingly, using `%X' to abort processing at conclusion. Reduce the number of test cases by grouping relocations the handling of which can now be verified together with a single source and dump. bfd/ * elfxx-mips.c (_bfd_mips_elf_relocate_section) <bfd_reloc_outofrange>: Use the `%X%H' rather than `%C' format for message.

2016-05-25MIPS/BFD: Report `bfd_reloc_outofrange' errors as suchMaciej W. Rozycki34-0/+456
A `bfd_reloc_outofrange' condition from `mips_elf_calculate_relocation' currently triggers the warning callback, which in the case of LD prints messages like: foo.o: In function `foo': (.text+0x0): warning: JALX to a non-word-aligned address or: foo.o: In function `foo': (.text+0x0): warning: PC-relative load from unaligned address and nothing else, which suggests this is a benign condition and link has otherwise successfully run to completion. This is however not the case, the link terminates right away with no further messages and no output produced. Use the general error or warning info callback then, preserving the message format. Also set a BFD error condition so that a failure is unambiguously reported. Complement the change with a set of suitable test suite additions. bfd/ * elfxx-mips.c (_bfd_mips_elf_relocate_section) <bfd_reloc_outofrange>: Call `->einfo' rather than `->warning'.

2016-05-25Skip an archive element if not added by linkerH.J. Lu7-3/+126
During archive rescan to resolve symbol references for files added by LTO, linker add_archive_element callback is called to check if an archive element should added. After all IR symbols have been claimed, linker won't claim new IR symbols and shouldn't add the LTO archive element. This patch updates linker add_archive_element callback to return FALSE when seeing an LTO archive element during rescan and changes ELF linker to skip such archive element. bfd/ PR ld/20103 * cofflink.c (coff_link_check_archive_element): Return TRUE if linker add_archive_element callback returns FALSE. * ecoff.c (ecoff_link_check_archive_element): Likewise. * elf64-ia64-vms.c (elf64_vms_link_add_archive_symbols): Skip archive element if linker add_archive_element callback returns FALSE. * elflink.c (elf_link_add_archive_symbols): Likewise. * pdp11.c (aout_link_check_ar_symbols): Likewise. * vms-alpha.c (alpha_vms_link_add_archive_symbols): Likewise. * xcofflink.c (xcoff_link_check_dynamic_ar_symbols): Likewise.

2016-05-20MIPS: Fix the encoding of immediates with microMIPS JALXMaciej W. Rozycki5-0/+51
The microMIPS JALX instruction shares the R_MICROMIPS_26_S1 relocation with microMIPS J/JAL/JALS instructions, however unlike the latters its encoded immediate argument is unusually shifted left by 2 rather than 1 in calculating the value used for the operation requested. We already handle this exception in `mips_elf_calculate_relocation' in LD, in a scenario where JALX is produced as a result of relaxing JAL for the purpose of making a cross-mode jump. We also get it right in the disassembler in `decode_micromips_operand'. What we don't correctly do however is processing microMIPS JALX produced by GAS from an assembly source, where a non-zero constant argument or a symbol reference with a non-zero in-place addend has been used. In this case the same calculation is made as for microMIPS J/JAL/JALS, causing the wrong encoding to be produced by GAS on making an object file, and then again by LD in the final link. The latter in particular causes the calculation, where the addend fits in the relocatable field, to produce different final addresses for the same source code depending on whether REL or RELA relocations are used. Correct these issues by special-casing microMIPS JALX in the places that have been previously missed. bfd/ * elfxx-mips.c (mips_elf_read_rel_addend): Adjust the addend for microMIPS JALX. gas/ * config/tc-mips.c (append_insn): Correct the encoding of a constant argument for microMIPS JALX.

The `am34-*-linux*' target cannot be configured for, `am34' is not a CPU name recognized by `config.sub'. It has never been, required code has not been contributed to GNU config, neither before nor since the addition of the target triplet to our configury with commit bfff16424942 ("Add MN10300 linker relaxation support for symbol differences") back in 2007.

2016-05-04LD/testsuite: Add STB_GNU_UNIQUE cross-linker testMaciej W. Rozycki3-2/+19
Some targets are only really, or at least regularly, regression-tested in a crossed configuration. Currently we only have native compiled test cases for the STB_GNU_UNIQUE feature in the linker test suite. This is nice, covering run-time semantics even, but quite often not run at all. Consequently a regression may remain unnoticed for long. Add a simple test case then to provide basic linker coverage with no need for a compiler or a native toolchain. ld/ * testsuite/ld-unique/unique.d: New test. * testsuite/ld-unique/unique.exp: Run the new test.

2016-05-03[AArch64] Also puts value in place for R_AARCH64_RELATIVEJiong Wang9-1/+89
When handling absolute relocations for global symbols bind within the shared object, AArch64 will generate one dynamic RELATIVE relocation, but won't apply the value for this absolution relocations at static linking stage. This is different from AArch64 gold linker and x86-64. This is not a bug as AArch64 is RELA, there is only guarantee that relocation addend is placed in the relocation entry. But some system softwares originally writen for x86-64 might assume AArch64 bfd linker gets the same behavior as x86-64, then they could take advantage of this buy skipping those RELATIVE dynamic relocations if the load address is the same as the static linking address. This patch makes AArch64 BFD linker applies absolution relocations at static linking stage for scenario described above. Meanwhile old AArch64 android loader has a bug (PR19163) which relies on current linker behavior as a workaround, so the same option --no-apply-dynamic-relocs added.
