2018-03-28PR ld/22972 on SPARC.Eric Botcazou2-7/+30
This is a regression for the corner case of a hidden symbol in a PIC/PIE binary which is subject to both a new-style GOTDATA relocation and an old-style GOT relocation. In this case, depending on the link order, the R_SPARC_RELATIVE dynamic relocation for the GOT slot needed because of the old-style relocation can be replaced with R_SPARC_NONE coming from the GOTDATA relocation. The fix simply records whether an old-style GOT relocation is seen for a symbol and prevents the R_SPARC_NONE from being generated in this case. bfd/ * elfxx-sparc.c (struct _bfd_sparc_elf_link_hash_entry): Add new flag has_old_style_got_reloc. (_bfd_sparc_elf_check_relocs) <GOT relocations>: Set it for old-style relocations. Fix a couple of long lines. (_bfd_sparc_elf_relocate_section) <R_SPARC_GOTDATA_OP>: Do not generate a R_SPARC_NONE for the GOT slot if the symbol is also subject to old-style GOT relocations. ld/ * testsuite/ld-sparc/sparc.exp: Add test for mixed GOTDATA/GOT relocs. * testsuite/ld-sparc/gotop-hidden.c: New file. * testsuite/ld-sparc/got-hidden32.s: Likewise. * testsuite/ld-sparc/got-hidden64.s: Likewise. * testsuite/ld-sparc/pass.out: Likewise.

2018-03-25x86-64: Add ENDBR64 to the TLSDESC PLT entryH.J. Lu2-13/+25
The TLSDESC entry in a lazy procedure linkage table is called indirectly with "callq *(%rax)". This patch adds an ENDBR64 to support indirect branch tracking in Intel CET. The TLSDESC PLT entry now looks like: 0xf3, 0x0f, 0x1e, 0xfa, /* endbr64 */ 0xff, 0x35, 8, 0, 0, 0, /* pushq GOT+8(%rip) */ 0xff, 0x25, 16, 0, 0, 0 /* jmpq *GOT+TDG(%rip) */ The BND prefix isn't needed since MPX isn't used for TLSDESC. bfd/ PR ld/23000 * elf64-x86-64.c (elf_x86_64_finish_dynamic_sections): Add ENDBR64 to the TLSDESC PLT entry. ld/ PR ld/23000 * testsuite/ld-x86-64/tlsdesc.pd: Updated.

2018-03-14PowerPC64 debian bug 886264, out-of-line save/restore functionsAlan Modra2-15/+25
This calculation in relocate_section if (stub_entry->stub_type == ppc_stub_save_res) relocation += (stub_sec->output_offset + stub_sec->output_section->vma + stub_sec->size - htab->sfpr->size - htab->sfpr->output_offset - htab->sfpr->output_section->vma); to adjust from the original out-of-line save/restore function address in sfpr to a copy at the end of stub_sec goes wrong when stub_sec is padded, because the copy is no longer at the end of stub_sec. The solution is to pad before copying sfpr, so the copy is always at the end of stub_sec. * elf64-ppc.c (sfpr_define): Adjust for stub_sec size having sfpr size added before defining alias symbols.

ifunc symbols found in note sections. Following on from PR 22929, I have found the same problem exists with other ifunc supporting targets too. Plus see this link for the bug being reported against the s390x binutils for Fedora rawhide: https://bugzilla.redhat.com/show_bug.cgi?id=1553705 So I am going to check in the patch below which applies the same change that H.J. made for the x86_64 target to the other affected targets.

2018-03-03PR ld/21900: MIPS: Fix relocation processing with undefined symbolsJames Cowgill2-4/+19
Currently, when `mips_elf_calculate_relocation' is asked to relocate an undefined symbol, it reports an error or a warning and immediately returns without performing the relocation. This is fine if the link fails, but if unresolved_syms_in_objects == RM_GENERATE_WARNING, the link will continue and output some unrelocated code, which is a regression from commit e7e2196da3f0 ("MIPS/BFD: Correctly report undefined relocations"). Fix this by continuing after calling the `undefined_symbol' hook unless this is an error condition. bfd/ PR ld/21900 * elfxx-mips.c (mips_elf_calculate_relocation): Only return after calling `undefined_symbol' hook if this is an error condition.
