2017-08-06Treat common symbol as undefined for --no-define-commonH.J. Lu12-6/+63
When --no-define-common is used to build shared library, treat common symbol as undefined so that common symbols that are referenced from a shared library to be assigned addresses only in the main program. This eliminates the unused duplicate space in the shared library, and also prevents any possible confusion over resolving to the wrong duplicate when there are many dynamic modules with specialized search paths for runtime symbol resolution. --no-define-common is only allowed when building a shared library. bfd/ PR ld/21903: * elflink.c (elf_link_add_object_symbols): Treat common symbol as undefined for --no-define-common. include/ PR ld/21903: * bfdlink.h (bfd_link_info): Add inhibit_common_definition. ld/ PR ld/21903: * ld.h (command_line): Remove inhibit_common_definition. * ldgram.y: Replace command_line.inhibit_common_definition with link_info.inhibit_common_definition. * ldlang.c (lang_common): Likewise. * lexsup.c (parse_args): Likewise. * ldmain.c (main): Only allow --no-define-common with -shared. * testsuite/ld-elf/pr21903.s: New file. * testsuite/ld-elf/pr21903a.d: Likewise. * testsuite/ld-elf/pr21903b.d: Likewise. * testsuite/ld-elf/pr21903c.d: Likewise. * testsuite/ld-elf/pr21903d.d: Likewise. * testsuite/ld-elf/pr21903e.d: Likewise.

2017-07-25__tls_get_addr_opt stub eh_frame infoAlan Modra5-3/+44
Since the __tls_get_addr_opt stub saves LR and makes a call, eh_frame info should be generated to describe how to unwind through the stub. The patch also changes the way the backend iterates over stubs, from looking at all sections in stub_bfd to which all dynamic sections are attached as well, to iterating over the group list, which gets just the stub sections. Most binaries will have just one or two stub groups, so this is a little faster. bfd/ * elf64-ppc.c (struct map_stub): Add tls_get_addr_opt_bctrl. (stub_eh_frame_size): New function.

2017-07-19LD/testsuite: Add 2**4 section alignment FILL script statement testMaciej W. Rozycki7-8/+97
Complement commit ffe54b3798db ("Pad sections according to current script FILL.") and add a FILL script statement test for targets that impose the minimum alignment of more than 2**2 for the `.text' section.

2017-07-18LD/testsuite: Conditionalize the placement of `.got' in GNU_RELROMaciej W. Rozycki2-1/+24
Complement commit d345186d0535 ("Check if GNU_RELRO segment is is generated") and exclude the presence of a `.got' section from implying the creation of a GNU_RELRO segment for targets which place the section along with small data, and therefore as it stands cannot have the section assigned to GNU_RELRO. This is because we currently only support a single GNU_RELRO segment and we place it at the beginning of regular data which is then separated from small data by read-write data. Currently the list of such targets consists of Alpha, Linux HPPA, NetBSD HPPA, OpenBSD HPPA, Meta, MIPS, Nios II, OpenRISC 1000, RISC-V, SH and X86-64, as determined by examining default linker scripts produced in a `--enable-targets=all' build for those that have DATA_SEGMENT_RELRO_END set and `.got' placed beyond. These targets do not set NO_SMALL_DATA or DATA_GOT in their respective files in ld/emulparams/*, hovever checking for the absence of these settings on its own is not very feasible due to the structure of these files and the lack of support for GNU_RELRO by some targets in the first place.

2017-07-07MIPS/LD: Fix a segfault from ELF `e_flags' access with non-ELF output BFDMaciej W. Rozycki6-6/+36
Fix a commit 861fb55ab50a ("Defer allocation of R_MIPS_REL32 GOT slots"), <https://sourceware.org/ml/binutils/2008-08/msg00096.html>, regression and a more recent: FAIL: ld-unique/pr21529 new LD test case failure, observed with all the relevant MIPS targets whenever the linker is invoked with one or more ELF inputs and the output format set to `binary'. The culprit is a segmentation fault caused in `mips_before_allocation' by a null pointer dereference, where an attempt is made to access the ELF file header's `e_flags' member, for the purpose of determining whether to produce a PLT and copy relocations, without first checking that the output BFD is ELF. The `e_flags' member is stored in BFD's private data pointed to by `tdep', which in the case of the `binary' BFD is null, causing the segmentation fault. With other non-ELF BFDs such as SREC `tdep' is not null and consequently no crash may happen and in that case random data will be interpreted as it was `e_flags'. Disable the access to `e_flags' then and all the associated checks and consequently never produce a PLT and copy relocations if output is not a MIPS ELF BFD, matching `_bfd_mips_elf_merge_private_bfd_data' that does not process `e_flags' in that case either and therefore does not let us decide here anyway if all the input objects included in the link are suitable for use with a PLT and copy relocations. ld/ * emultempl/mipself.em (mips_before_allocation): Avoid ELF processing if not MIPS ELF. * testsuite/ld-mips-elf/binary.d: New test. * testsuite/ld-mips-elf/binary.ld: New test linker script. * testsuite/ld-mips-elf/binary.s: New test source. * testsuite/ld-mips-elf/mips-elf.exp: Run the new test.

2017-07-01MIPS/GAS: Use non-zero frag offset directly in PIC branch relaxationMaciej W. Rozycki7-0/+116
Use frag symbols with a non-zero offset directly in `fix_new_exp' calls made in PIC branch relaxation. There is no need here to make a helper symbol to hold the result of a `symbol+offset' calculation requested as only branches to local symbols are relaxed and in this case the LO16 part of the PIC address load sequence will have the offset accounted for in calculation against the local GOT entry retrieved as the GOT16 high part. Consequently actual code produed is identical whether a helper symbol is used or the original `symbol+offset' expression used directly. Verify that this is indeed the case with GAS and LD tests. gas/ * config/tc-mips.c (md_convert_frag): Don't make a helper expression symbol for `fix_new_exp' called with a non-zero offset. * testsuite/gas/mips/relax-offset.d: New test. * testsuite/gas/mips/mips1@relax-offset.d: New test. * testsuite/gas/mips/r3000@relax-offset.d: New test. * testsuite/gas/mips/r3900@relax-offset.d: New test. * testsuite/gas/mips/micromips@relax-offset.d: New test. * testsuite/gas/mips/relax-offset.l: New stderr output. * testsuite/gas/mips/relax-offset.s: New test source. * testsuite/gas/mips/mips.exp: Run the new tests. ld/ * testsuite/ld-mips-elf/relax-offset.dd: New test. * testsuite/ld-mips-elf/relax-offset.gd: New test. * testsuite/ld-mips-elf/relax-offset-umips.dd: New test. * testsuite/ld-mips-elf/relax-offset-umips.gd: New test. * testsuite/ld-mips-elf/relax-offset.ld: New test linker script. * testsuite/ld-mips-elf/mips-elf.exp: Run the new tests.

2017-06-27Fix PR 13402Senthil Kumar Selvaraj3-0/+31
Fix incorrect adjustment of diff relocs when relaxing, and thus the resulting source line to address mismatch. Fix two issues when adjusting diff relocs to account for deleted bytes. 1. Don't adjust the difference if the end address is the shrinked insn's address i.e. use < instead of <=. The relaxation code deletes count bytes from or after shrinked_insn_address, so the difference between start_address and end_address should remain unchanged in this case. 2. Adjust the reloc addend if the difference is to be adjusted and symval + reloc addend is past the shrinked insn address. This is because for a typical sym1 - sym2 diff reloc, sym1 is .text + irel->r_addend, and the addend should be reduced to account for the shrinked insn. For example, assume the reloc value is .text + 0x8 with .text = 0, the diff value in the object file = 0x4, and shrinked_insn_address = 0x4 with count = 0x2. Then the existing code writes 0x2 into the object file to account for the deleted bytes, as shrinked_insn_address lies between 0x8 and 0x8 - 0x4 = 0x4, but leaves the addend as is. The next time the reloc is looked at, the code sees if a shrinked_insn_address lies between 0x8 and 0x8 - 0x2 = 0x6, instead of 0x6 and 0x4. If there happens to be one, then the diff value in the object file ends up getting reduced again. bfd/ 2017-06-27 Senthil Kumar Selvaraj <senthil_kumar.selvaraj@atmel.com> PR ld/13402 * elf32-avr.c (elf32_avr_adjust_diff_reloc_value): Adjust reloc addend if necessary.

This lets callers of this procedure request to examine MIPS ABI Flags in addition to the `e_flags' member of the ELF file header so as to verify that flags are merged correctly by LD. The presence of further arguments triggers this verification, in which case `readelf' is called with the `-A' option additionally specified and the ISA member, the ISA Extension member and the ASEs member will be examined as per the arguments. Unlike with `readelf -h' output consider a failure to retrieve the member requested a test case failure rather than an unresolved result. This is because unlike with the `e_flags' member of the ELF file header which is always there in any valid ELF file the MIPS ABI Flags structure is optional in LD output and the absence of this structure when expected is surely a bug in LD. ld/ * testsuite/ld-mips-elf/mips-elf-flags.exp (good_combination): Add an `args' final argument and examination code for `readelf -A' output. Update procedure description accordingly.
2017-06-27MIPS/LD/testsuite: mips-elf-flags: Use `remote_exec' to call `readelf'Maciej W. Rozycki2-2/+12
For ELF file header flag verification done in `good_combination' in the `mips-elf-flags.exp' test script the version of `readelf' built along with the rest of binutils has to be used rather than any such executable already present on the build system, so that flags recognized by the tool match those supported by LD being tested. Use `remote_exec' as elsewhere in the LD test framework and also with GAS and LD used here, getting and arranging for extra reporting of `readelf' calls included in test logs on this occasion as well. ld/ * testsuite/ld-mips-elf/mips-elf-flags.exp (good_combination): Use `remote_exec' to call `readelf'. Log the command issued.
2017-06-27MIPS/LD/testsuite: mips-elf-flags: Use `-h' only with `readelf'Maciej W. Rozycki2-2/+7
For the purpose of link-time object compatibility handling verification code in the `good_combination' procedure from the `mips-elf-flags.exp' test script only examines the `e_flags' member of the ELF file header and ignores data from any ELF program or section headers present. Use `readelf -h' rather than `readelf --headers' then to obtain data for examination, avoiding unnecessary processing to extract this extraneous information. ld/ * testsuite/ld-mips-elf/mips-elf-flags.exp (good_combination): Use `readelf -h' rather than `readelf --headers'.
2017-06-26MIPS/BFD: Consistently mark the LSI CW4010 as a MIPS II processorMaciej W. Rozycki3-0/+31
Make BFD agree with GAS and mark the LSI MiniRISC CW4010 processor core (for an odd reason referred to as LSI R4010 across our code base) as a MIPS II processor in BFD as well, fixing a bug that has been there since forever and addressing linker warnings like: $ as -m4010 empty.s -o 4010.o $ ld -r 4010.o -o 4010-r.o ld: 4010.o: warning: Inconsistent ISA between e_flags and .MIPS.abiflags $ due to the ISA level being recorded as MIPS III in ELF file header's `e_flags' vs MIPS II in the MIPS ABI Flags section: $ readelf -Ah 4010.o ELF Header: Magic: 7f 45 4c 46 01 02 01 00 00 00 00 00 00 00 00 00 Class: ELF32 Data: 2's complement, big endian Version: 1 (current) OS/ABI: UNIX - System V ABI Version: 0 Type: REL (Relocatable file) Machine: MIPS R3000 Version: 0x1 Entry point address: 0x0 Start of program headers: 0 (bytes into file) Start of section headers: 348 (bytes into file) Flags: 0x20821000, 4010, o32, mips3 Size of this header: 52 (bytes) Size of program headers: 0 (bytes) Number of program headers: 0 Size of section headers: 40 (bytes) Number of section headers: 11 Section header string table index: 10 Attribute Section: gnu File Attributes Tag_GNU_MIPS_ABI_FP: Hard float (double precision) MIPS ABI Flags Version: 0 ISA: MIPS2 GPR size: 32 CPR1 size: 32 CPR2 size: 0 FP ABI: Hard float (double precision) ISA Extension: LSI R4010 ASEs: None FLAGS 1: 00000000 FLAGS 2: 00000000 $ Available documentation[1][2] clearly indicates the LSI CW4010 processor is only backwards compatible with the MIPS R4000 processor as far as the latter's 32-bit instructions are concerned and consequently can only be considered a MIPS II ISA implementation (with vendor extensions). This fixes an LD testsuite failure: FAIL: MIPS incompatible objects: "-march=r4010 -32" "-march=r4650 -32" triggered for the `mips-sgi-irix5' and `mips-sgi-irix6' targets.

2017-06-26LD: Fix .startof.SECNAME/.sizeof.SECNAME tests for MIPS/IRIXMaciej W. Rozycki5-8/+16
Correct .startof.SECNAME/.sizeof.SECNAME tests for MIPS/IRIX targets, complementing commit dc74becf498f ("ld: Add tests for -Ur") and commit da614360f520 ("ld: Add tests for .startof.SECNAME/.sizeof.SECNAME") with subsequent updates, and in reference to commit cbd0eecf261c ("Always define referenced __start_SECNAME/__stop_SECNAME") and commit 7dba9362c172 ("Rewrite __start and __stop symbol handling"). These targets set the STT_OBJECT type for non-function symbol references, according to `elf_frob_symbol' code in gas/config/obj-elf.c: /* The Irix 5 and 6 assemblers set the type of any common symbol and any undefined non-function symbol to STT_OBJECT. We try to be compatible, since newer Irix 5 and 6 linkers care. However, we only set undefined symbols to be STT_OBJECT if we are on Irix, because that is the only time gcc will generate the necessary .global directives to mark functions. */ if (S_IS_COMMON (symp)) symbol_get_bfdsym (symp)->flags |= BSF_OBJECT; if (strstr (TARGET_OS, "irix") != NULL && ! S_IS_DEFINED (symp) && (symbol_get_bfdsym (symp)->flags & BSF_FUNCTION) == 0) symbol_get_bfdsym (symp)->flags |= BSF_OBJECT; and consequently entries in the symbol table listing from `readelf' produced with these tests do not match the NOTYPE pattern expected, causing test suite failures: FAIL: ld-elf/sizeofa FAIL: ld-elf/sizeofc FAIL: ld-elf/startofa FAIL: ld-elf/startofc specifically with the `mips-sgi-irix5' and `mips-sgi-irix6' targets. Given that it does not matter for the feature covered by these tests whether the type of the symbols produced is STT_NOTYPE or STT_OBJECT adjust the problematic cases to accept either type, removing the failures observed. ld/ * testsuite/ld-elf/sizeofa.d: Also accept the OBJECT type for the symbols examined. * testsuite/ld-elf/sizeofc.d: Likewise. * testsuite/ld-elf/startofa.d: Likewise. * testsuite/ld-elf/startofc.d: Likewise.

2017-06-26Don't attach linker created section to --just-syms bfdAlan Modra2-4/+12
All sections on a --just-syms bfd are discarded from the output, so attaching linker created sections to such a bfd results in errors. In other cases, like the .note.GNU-stack check, it's wrong to have a --just-syms object potentially affect the output. bfd/ * elflink.c (_bfd_elf_link_create_dynstrtab): Don't make dynobj a --just-syms bfd.

2017-06-24[ARM] Add linker support for ARMv8-RThomas Preud'homme8-0/+55
=== Context === This patch is part of a patch series to add support for ARMv8-R architecture. Its purpose is to add support for ARMv8-R in the linker. === Patch description === This patch is composed of 3 changes: 1) The main change is the addition of the logic for merging a file whose Tag_CPU_arch build attribute is 15 (ARMv8-R). Namely, all pre-ARMv8 are merged into ARMv8-R as well as ARMv8-R itself. ARMv8-A (14) merges into ARMv8-A. ARMv8-M Baseline (16) and Mainline (17) are not allowed to merge merge with ARMv8-R. Note that merging only occurs if the two profiles are identical or one is S (Application or Realtime) and the other is R. 2) using_thumb_only, using_thumb2_bl, using_thumb2 and arch_has_arm_nop are updated according to capabilities of ARMv8-R and their BFD_ASSERT updated to reflect that the logic is valid for ARMv8-R. 3) 2 build attribute merging tests are added to test the first change. 2017-06-24 Thomas Preud'homme <thomas.preudhomme@arm.com> bfd/ * elf32-arm.c (using_thumb_only): Update list of architectures in BFD_ASSERT for which the logic is valid. (using_thumb2_bl): Likewise. (using_thumb2): Likewise and return true for ARMv8-R. (arch_has_arm_nop): Likewise. (tag_cpu_arch_combine): New v8r table for ARMv8-R Tag_CPU_arch merging logic. Update commentis for value 15 of v8m_baseline, v8m_mainline and v4t_plus_v6_m arrays. Use v8r array to decide merging of value 15 of Tag_CPU_arch. ld/ * testsuite/ld-arm/arm-elf.exp (EABI attribute merging 11): New test.
