2015-08-03Fix ChangeLog for "FAIL: -Bsymbolic-functions" for cris-linux in ldHans-Peter Nilsson1-1/+1
It's bfd_link_info, not elf_link_hash_entry, for the old reference: * elf32-cris.c (cris_elf_relocate_section) (elf_cris_finish_dynamic_symbol, cris_elf_check_relocs) (elf_cris_discard_excess_dso_dynamics): Use SYMBOLIC_BIND, not just bfd_link_info->symbolic, to check if a symbol should be bound symbolically.

2015-07-30Don't change the default symbol for relocatable linkH.J. Lu1-0/+8
We should change the default symbol for the versioned symbol only when not performing a relocatable link. bfd/ PR ld/18735 * elflink.c (_bfd_elf_add_default_symbol): Add the default symbol if not performing a relocatable link.

This patch changes "ld -r" not to set link_info.executable.

2015-07-28Fallout from "Reorder more powerpc64 sections for -z relro"Alan Modra1-0/+6
Commit 23283c1b changed the layout of some bss style sections on powerpc64, but neglected to add a page gap before the third PT_LOAD segment created by this reording. Without a page gap we get two PT_LOAD headers that overlap by one page in memory. That shouldn't be allowed because the dynamic loader will load garbage from the first page of the last segment over the last page of the previous segment. bfd/ * elf.c (_bfd_elf_map_sections_to_segments): Do not make a new segment for loaded sections after nonloaded sections if the sections are on the same page. ld/testsuite/ * ld-powerpc/elfv2so.d: Update

2015-07-24bfd_get_section_by_name_if hash chain traversalAlan Modra1-0/+5
This function stops too soon, as I found when the hash chain happened to contain two .debug_macro sections and a .bss section: .debug_macro -> .bss -> .debug_macro * section.c (bfd_get_section_by_name_if): Iterate over entire hash chain.
2015-07-23Fix DT_MIPS_RLD_MAP_REL tag for n64 target and 32-bit host.Joseph Myers1-0/+6
For the case of MIPS n64 target and 32-bit host, the computation of the DT_MIPS_RLD_MAP_REL tag involves sdyn->output_section->vma + sdyn->output_offset (64-bit) being added to b (32-bit host pointer), so losing the high part and resulting in an incorrect DT_MIPS_RLD_MAP_REL tag, and all dynamically linked glibc tests failing for n64. This patch fixes this (spot-tested with glibc tests; however, I don't have a self-contained testcase for this bug). * elfxx-mips.c (_bfd_mips_elf_finish_dynamic_sections) <DT_MIPS_RLD_MAP_REL>: Add target address to host address difference, not to host pointer.
2015-07-22Fix ppc64 ELFv1 assertion failureAlan Modra1-0/+5
Bogus assembly can hit an assertion in opd_entry_value when the symbol referenced by a function descriptor is undefined. Worse, the code after the assert copies unitialised memory to return the code section. This uninitialised pointer can later be dereferencd, possibly causing a linker segmentation fault. * elf64-ppc.c (opd_entry_value): Remove assertion. Instead, return -1 if symbol referenced is not defined. Tidy.

The output SHF_COMPRESSED section size is different from input if ELF classes of input and output aren't the same.

2015-06-24Don't convert R_X86_64_GOTPCREL if it will overflowH.J. Lu1-0/+7
When converting "mov foo@GOTPCREL(%rip), %reg" to "lea foo(%rip), %reg" with R_X86_64_PC32 relocation, it may overflow if the target section is more than 2GB away. This patch estimates distance between mov instruction and the target section. We convert R_X86_64_GOTPCREL to R_X86_64_PC32 only if their distance is less than 2GB.

2015-06-15Allow gdb to find debug symbols file by build-id for PE file format alsoJon Turney1-0/+12
This promotes BFD's struct elf_build_id to the generic struct bfd_build_id, populated when an ELF or PE BFD is read. gdb is updated to use that, and to use the build-id to find symbols for PE files also. There is currently no generic way to extract the build-id from an object file, perhaps an option to objdump to do this might make sense? On x86_64-pc-cygwin, gdb's sepdebug.exp changes: -# of unsupported tests 1 +# of expected passes 90 I don't seem to get consistent testsuite runs on i686-linux-gnu, but there don't appear to be any regressions. bfd/ChangeLog: 2015-06-10 Jon Turney <jon.turney@dronecode.org.uk> * elf-bfd.h : Remove struct elf_build_id. * bfd.c : Add struct bfd_build_id. * bfd-in2.h: Regenerate. * elf.c (elfobj_grok_gnu_build_id): Update to use bfd_build_id. * libpei.h: Add protoype and macros for bfd_XXi_slurp_codeview_record. * peXXigen.c (_bfd_XXi_slurp_codeview_record): Make public * peicode.h (pe_bfd_read_buildid): Add.

When building a shared lib from non-PIC objects, we'll get dynamic text relocations. These need to move with any insns we move.
