With copy relocation, address of protected data defined in the shared library may be external.

2015-02-11Correct GOLD PowerPC64 local-dynamic TLS linker optimizationAlan Modra2-6/+14
Similar to b86ac8e3 * powerpc.cc (Target_powerpc::Relocate::relocate): Correct GOT_TLSLD and GOT_TLSGD to LE optimization.
2015-02-11Correct PowerPC64 local-dynamic TLS linker optimizationAlan Modra9-9/+211
The linker hardcoded r3 into a local-dynamic to local-exec TLS optimization sequence. This is normally the case since r3 is required as a parameter to (the optimized out) __tls_get_addr call. However, it is possible for a compiler, LLVM in this case, to set up the parameter value in another register then copy it to r3 before the call. When fixing this problem, I noticed that ppc32 had another bug when optimizing away one of the TLS insns to a nop. The patch also tidies a mask used by global-dynamic to initial-exec TLS optimization, to just select the fields needed. Leaving the offset in the instruction wasn't a bug since it will be overwritten anyway. bfd/ * elf64-ppc.c (ppc64_elf_relocate_section): Correct GOT_TLSLD optimization. Tidy mask for GOT_TLSGD optimization. * elf32-ppc.c (ppc_elf_relocate_section): Likewise. Correct location of nop zapping high insn too. ld/testsuite/ * ld-powerpc/tlsld.d, * ld-powerpc/tlsld.s: New test. * ld-powerpc/tlsld32.d, * ld-powerpc/tlsld32.s: New test. * ld-powerpc/powerpc.exp: Run them.

2015-02-11ld: Update expected test results for 32-bit hosts.Andrew Burgess3-11/+15
Tests that I added in commit c05b575a8dfabab6af5d8586d1a5c0c67f819ac2 fails on 32-bit hosts due to differences in whitespace. This patch updates the expected output patterns to be more accepting of differences in whitespace, the tests should now pass. ld/testsuite/ChangeLog: * ld-scripts/provide-4-map.d: Update expected output. * ld-scripts/provide-5-map.d: Likewise.
2015-02-11ld: Don't evaluate unneeded PROVIDE expressions.Andrew Burgess11-2/+93
When creating a linker mapfile (using -Map=MAPFILE), we previously would always try to evaluate the expression from a PROVIDE statement. However, this is not always safe, consider: PROVIDE (foo = 0x10); PROVIDE (bar = foo); In this example, if neither 'foo' or 'bar' is needed, then while generating the linker mapfile evaluating the expression for 'foo' is harmless (just the value 0x10). However, evaluating the expression for 'bar' requires the symbol 'foo', which is undefined. This used to cause a fatal error. This patch changes the behaviour, so that when the destination of the PROVIDE is not defined (that is the PROVIDE is not going to provide anything) the expression is not evaluated, and instead a special string is displayed to indicate that the linker is discarding the PROVIDE statement. This change not only fixes the spurious undefined symbol error, but also means that a user can now tell if a PROVIDE statement has provided anything by inspecting the linker mapfile, something that could not be done before. ld/ChangeLog: * ldlang.c (print_assignment): Only evaluate the expression for a PROVIDE'd assignment when the destination is being defined. Display a special message for PROVIDE'd symbols that are not being provided. ld/testsuite/ChangeLog: * ld-scripts/provide-4.d: New file. * ld-scripts/provide-4-map.d: New file. * ld-scripts/provide-4.t: New file. * ld-scripts/provide-5.d: New file. * ld-scripts/provide-5.s: New file. * ld-scripts/provide-5-map.d: New file. * ld-scripts/provide-5.t: New file. * ld-scripts/provide.exp: Run the provide-4.d and provide-5.d tests.
2015-02-11ld/testing: run_dump_test can now check linker mapfiles.Andrew Burgess4-9/+41
Add a new option 'map' to the ld run_dump_test mechanism. When the 'map' option is given run_dump_test will ensure that there is a -Map=MAPFILE present in the linker command line, adding one if needed. The MAPFILE is then compared with the file passed to the new 'map' option using the regexp_diff function. This should make it slightly easier to write tests that check the linker mapfile output. The only test I found that already compares mapfile content is updated to use the new mechanism. ld/testsuite/ChangeLog: * ld-scripts/overlay-size.d: Add 'map' option. * ld-scripts/overlay-size.exp: Remove manual check of mapfile. * lib/ld-lib.exp (run_dump_test): Add support for new 'map' option, checking linker mapfile output.
2015-02-11Fix garbage collection of common symbols for powerpc64Alan Modra2-1/+6
I forgot powerpc64 has its own gc_mark_dynamic_ref. PR ld/17615 * elf64-ppc.c (ppc64_elf_gc_mark_dynamic_ref): Don't drop ELF_COMMON_DEF syms.
2015-02-11Fix garbage collection of common symbolsAlan Modra16-37/+61
Running lang_common before garbage collection means slightly less work in garbage collection code, since common symbols should no longer appear there. It does have the side effect of keeping linker script symbols (at least those defined outside of sections) global too, hence some testsuite churn. bfd/ PR 17165 * elf-bfd.h (ELF_COMMON_DEF): Note that this might be true for linker script assignments too. * elflink.c (elf_gc_sweep_symbol): Don't drop ELF_COMMON_DEF syms. (bfd_elf_gc_mark_dynamic_ref_symbol): Similarly. ld/ PR 17165 * ldlang.c (lang_process): Run lang_common before lang_gc_sections. ld/testsuite/ * ld-gc/pr14265.d, * ld-cris/tls-gc-68.d, * ld-cris/tls-gc-69.d, * ld-cris/tls-gc-70.d, * ld-cris/tls-gc-71.d, * ld-cris/tls-gc-75.d, * ld-cris/tls-gc-76.d, * ld-cris/tls-gc-79.d, * ld-mmix/bpo-10.d, * ld-mmix/bpo-11.d: Update.
2015-02-11Omit section dynsyms for any linker created sectionAlan Modra2-11/+7
This is a simplification, and fixes a testcase I had where an empty powerpc64 .branch_lt section was chosen for the data_index_section dynamic symbol and thus wasn't removed. * elflink.c (_bfd_elf_link_omit_section_dynsym): Return true for any output section matching a linker created dynobj section.
2015-02-11Fix ARM fail of gap testAlan Modra2-44/+54
ld-elf/gap test was failing due to the ARM backend attempting to output arch symbols when ld -s (strip all symbols) is in force. This patch stops that happening and tidies the code a little. PR 17842 * elflink.c (elf_link_output_sym): Assert elf_onesymtab set. (bfd_elf_final_link): Always create a symbol table when emit_relocs. Don't assign symtab file position unless symbols will be output. Merge blocks with condition in common. Don't call elf_backend_output_arch_local_syms or elf_backend_output_arch_syms unless other symbols are output. Move assignment of symtab_shndx file position. Localize variable.

2015-02-11Delete unnecessary code copying SHF_SH5_ISA32 flagAlan Modra5-21/+30
Since 2006, commit d270463e9, _bfd_elf_copy_private_section_data has copied over SHF_MASKOS and SHF_MASKPROC flags. That makes the buggy code in sh_elf64_copy_private_data_internal redundant. bfd/ PR 17755 * elf64-sh64.c (sh_elf64_copy_private_data_internal): Delete code copying SHF_SH5_ISA32. binutils/testsuite/ * binutils-all/strip-11.d: New test. * binutils-all/objcopy.exp: Run it.
2015-02-11Don't create .eh_frame_hdr on shared lib bfdAlan Modra2-1/+9
If no object files have .eh_frame, but some shared library does, then ld creates a .eh_frame_hdr section using the shared library bfd. This is silly since shared library .eh_frame sections don't contribute to the output .eh_frame and thus no .eh_frame_hdr is needed. Also, the bfd section list and count is cleared for shared libraries, and a zero section count used as a flag in lang_check to omit a call to bfd_merge_private_bfd_data for shared libraries. If we create a section on a shared lib bfd then ld will wrongly attempt to merge the shared library private bfd data. PR 17742 * ld/emultempl/elf32.em (gld${EMULATION_NAME}_after_open): Exclude shared libraries in loop looking for .eh_frame sections. Similarly for build-id loop.
