ELF: Call check_relocs after opening all inputs For all ELF targers, call check_relocs after opening all inputs and garbage collection. Since the symbol resolution is known, check_relocs can be simplified. Also garbage collection doesn't need to undo what check_relocs has done for symbols which have been garbage collected. Since ELF targets never see the removed sections, gc_sweep_hook can be removed from elf_backend_data and we can avoid GOT/PLT with garbage collection now. Set link_info.check_relocs_after_open_input to TRUE for all linker targets which use ELF linker and update garbage collection tests to remove unused GOT section. ldemul_after_check_relocs is added for powerpc to support --secure-plt, --bss-plt and --sdata-got. Tested natively without regressions on i686, x86-64 and x32.

ELF/BFD: Handle both variants of the 64-bit Linux core PRPSINFO note Fix commit 70a38d42c5b3 ("New entry points for writing Linux NT_PRPSINFO notes."), <https://sourceware.org/ml/binutils/2013-02/msg00023.html>, and handle both variants of the 64-bit Linux core PRPSINFO note across all targets. The 64-bit Linux core PRPSINFO note matches the 64-bit kernel structure, defined as follows: (gdb) ptype struct elf_prpsinfo type = struct elf_prpsinfo { char pr_state; char pr_sname; char pr_zomb; char pr_nice; unsigned long pr_flag; __kernel_uid_t pr_uid; __kernel_gid_t pr_gid; pid_t pr_pid; pid_t pr_ppid; pid_t pr_pgrp; pid_t pr_sid; char pr_fname[16]; char pr_psargs[80]; } (gdb) where the individual data types of most members are the same across all 64-bit Linux ports, with the exception of `__kernel_uid_t' and `__kernel_gid_t'. These are defined in <asm-generic/posix_types.h> as 32-bit `unsigned int' by default, however overridden as 16-bit `unsigned short' in port-specific <asm/posix_types.h> for the SuperH target. The default is already handled, as from the commit referred. Add the other variant then and provide a backend flag to switch between the two cases possible, with the 32-bit one being the default and the 16-bit one explicitly selected. Set the flag in the SuperH target backend. This arrangement is analogous to how the 32-bit Linux core PRPSINFO note is handled. bfd/ * elf-bfd.h (elf_backend_data): Add `linux_prpsinfo64_ugid16' member. * elf-linux-core.h (elf_external_linux_prpsinfo64): Rename to...

These are defined in <asm-generic/posix_types.h> as 32-bit `unsigned int' by default, however overridden as 16-bit `unsigned short' in port-specific <asm/posix_types.h> for a few targets, mostly earlier ports of Linux, specifically: ARM, CRIS, FR-V, M32R, m68k, MN10300/AM33, s390, SuperH, SPARC and i386. The default is the same as the PowerPC variant already handled, as from the commits referred. Make the special PowerPC case generic then, removing the GDB part, and provide a backend flag to switch between the two cases possible, with the 32-bit one being the default and the 16-bit one explicitly selected.

ELF/BFD: Fix padding in `elf_external_linux_prpsinfo64' Fix commit 70a38d42c5b3 ("New entry points for writing Linux NT_PRPSINFO notes."), <https://sourceware.org/ml/binutils/2013-02/msg00023.html>, and move the padding of the `elf_external_linux_prpsinfo64' structure to match the corresponding 64-bit Linux kernel `elf_prpsinfo' structure. The 64-bit kernel structure is defined as follows: (gdb) ptype struct elf_prpsinfo type = struct elf_prpsinfo { char pr_state; char pr_sname; char pr_zomb; char pr_nice; unsigned long pr_flag; __kernel_uid_t pr_uid; __kernel_gid_t pr_gid; pid_t pr_pid; pid_t pr_ppid; pid_t pr_pgrp; pid_t pr_sid; char pr_fname[16]; char pr_psargs[80]; } (gdb) print /x &((struct elf_prpsinfo *)0)->pr_nice $1 = 0x3 (gdb) print /x &((struct elf_prpsinfo *)0)->pr_flag $2 = 0x8 (gdb) print /x &((struct elf_prpsinfo *)0)->pr_uid $3 = 0x10 (gdb) print sizeof(((struct elf_prpsinfo *)0)->pr_flag) $4 = 8 (gdb) with implicit padding present before the `pr_flag' member, to correctly align it to a multiple of 8. Conversely `elf_external_linux_prpsinfo64' has padding after its `pr_flag' member: (top-gdb) ptype struct elf_external_linux_prpsinfo64 type = struct elf_external_linux_prpsinfo64 { char pr_state; char pr_sname; char pr_zomb; char pr_nice; char pr_flag[8]; char gap[4]; char pr_uid[4]; char pr_gid[4]; char pr_pid[4]; char pr_ppid[4]; char pr_pgrp[4]; char pr_sid[4]; char pr_fname[16]; char pr_psargs[80]; } (top-gdb) print /x &((struct elf_external_linux_prpsinfo64 *)0)->pr_nice $1 = 0x3 (top-gdb) print /x &((struct elf_external_linux_prpsinfo64 *)0)->pr_flag $2 = 0x4 (top-gdb) print /x &((struct elf_external_linux_prpsinfo64 *)0)->pr_uid $3 = 0x10 (top-gdb) and consequently `pr_flag' is misplaced.

PR21167, relocation sections not included in groups This fixes a wart I've known about for years, but haven't done anything about because BFD treats relocation sections as an adjunct to the section they relocate. SHF_GROUP on the section thus implicitly applies to its relocation section(s), but it is an error that the reloc sections aren't part of the group. Like many patches to gas, this wasn't as straightforward as it could be due to a number of backends, i386, cr16 and others, removing relocs in tc_get_reloc rather than marking them as "done" earlier in md_apply_reloc. So it isn't possible for the group support to reliably detect the presence of relocs by looking at fixups earlier than write_relocs. However the group support needs to create signature symbols, and that must be done before the symbol table is frozen, before write_relocs. So split off the group sizing from elf_adjust_symtab and put it in elf_frob_file_after_relocs. bfd/ PR 21167 * elf.c (_bfd_elf_setup_sections): Don't trim reloc sections from groups.

Support %Lx, %Lu, %Ld in _bfd_error_handler format One way to print 64-bit bfd_vma or bfd_size_type values on 32-bit hosts is to cast the value to long long and use the 'll' modifier in printf format strings. However, that's awkward because we also support the Microsoft C library printf that uses 'I64' as a modifier instead, and having variants of translated strings would not endear us to the translation project. So, rewrite the 'll' modifier in _doprint for Microsoft. Even with that capability it's not so nice for 32-bit code to need casts to long long, so this patch makes 'L' a modifier for bfd_vma rather than an alias for 'll'. I've then used the new 'L' modifier to fix selected format strings. * bfd.c (_doprnt): Rewrite "ll" and "L" modifiers to "I64" for __MSVCRT__. Support "L" modifier for bfd_vma.

Fix PR 13402 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.

[ARM] Add linker support for ARMv8-R === 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.

x86: Support Intel IBT with IBT property and IBT-enable PLT To support IBT in Intel Control-flow Enforcement Technology (CET) instructions: https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf #define GNU_PROPERTY_X86_FEATURE_1_AND 0xc0000002 #define GNU_PROPERTY_X86_FEATURE_1_IBT (1U << 0) are added to GNU program properties to indicate that all executable sections are compatible with IBT when ENDBR instruction starts each valid target where an indirect branch instruction can land. GNU_PROPERTY_X86_FEATURE_1_IBT is set on output only if it is set on all relocatable inputs. The followings changes are made to the Procedure Linkage Table (PLT): 1. For 64-bit x86-64, PLT is changed to PLT0: push GOT[1] bnd jmp *GOT[2] nop ... PLTn: endbr64 push namen_reloc_index bnd jmp PLT0 together with the second PLT section: PLTn: endbr64 bnd jmp *GOT[namen_index] nop BND prefix is also added so that IBT-enabled PLT is compatible with MPX. 2. For 32-bit x86-64 (x32) and i386, PLT is changed to PLT0: push GOT[1] jmp *GOT[2] nop ... PLTn: endbr64 # endbr32 for i386. push namen_reloc_index jmp PLT0 together with the second PLT section: PLTn: endbr64 # endbr32 for i386. jmp *GOT[namen_index] nop BND prefix isn't used since MPX isn't supported on x32 and BND registers aren't used in parameter passing on i386. GOT is an array of addresses. Initially, GOT[namen_index] is filled with the address of the ENDBR instruction of the corresponding entry in the first PLT section. The function, namen, is called via the ENDBR instruction in the second PLT entry. GOT[namen_index] is updated to the actual address of the function, namen, at run-time. 2 linker command line options are added: 1. -z ibtplt: Generate IBT-enabled PLT. 2. -z ibt: Generate GNU_PROPERTY_X86_FEATURE_1_IBT in GNU program properties as well as IBT-enabled PLT. bfd/ * elf32-i386.c (elf_i386_lazy_ibt_plt0_entry): New.

Rewrite __start and __stop symbol handling This arranges for __start and __stop symbols to be defined before garbage collection, for all target formats. That should allow the COFF and PE --gc-sections to keep a singleton orphan input section, a feature lost by 2017-06-13 commit cbd0eecf26. The fancier ELF treatment of keeping all input sections associated with a __start or __stop symbol, from 2015-10-23 commit 1cce69b9dc, is retained. .startof. and .sizeof. symbols are deliberately not defined before garbage collection, so these won't affect garbage collection of sections. The patch also ensures __start, __stop, .startof. and .sizeof. symbols are defined before target size_dynamic_sections is called, albeit with a preliminary value, so that target code doesn't need to cope with a symbol changing from undefined at size_dynamic_sections to defined at relocate_section. Also, a number of problems with the testcases have been fixed.

Always define referenced __start_SECNAME/__stop_SECNAME Currently, linker will define __start_SECNAME and __stop_SECNAME symbols only for orphaned sections. However, during garbage collection, ELF linker marks all sections with references to __start_SECNAME and __stop_SECNAME symbols as used even when section SECNAME isn't an orphaned section and linker won't define __start_SECNAME nor __stop_SECNAME. And ELF linker stores the first input section whose name matches __start_SECNAME or __stop_SECNAME in u.undef.section for garbage collection. If these symbols are provided in linker script, u.undef.section is set to the section where they will defined by linker script, which leads to the incorrect output. This patch changes linker to always define referenced __start_SECNAME and __stop_SECNAME if the input section name is the same as the output section name, which is always true for orphaned sections, and SECNAME is a C identifier. Also __start_SECNAME and __stop_SECNAME symbols are marked as hidden by ELF linker so that __start_SECNAME and __stop_SECNAME symbols for section SECNAME in different modules are unique. For garbage collection, ELF linker stores the first matched input section in the unused vtable field. bfd/ PR ld/20022 PR ld/21557 PR ld/21562 PR ld/21571 * elf-bfd.h (elf_link_hash_entry): Add start_stop.

[bfd][arm] Don't assert on suspicious build attributes in input file It's generally a bad idea to use assertions to validate our idea of what an input file looks like. We need to be as liberal as possible in what we accept with respect to standards and conservative with what we produce. Currently, if gcc is used to produce an assembler file which contains only data, but the FPU is set to fpv4-sp-d16 and mfloat-abi=hard, then the following attributes will be set in the output: .cpu arm7tdmi .eabi_attribute 27, 1 @ Tag_ABI_HardFP_use .eabi_attribute 28, 1 @ Tag_ABI_VFP_args .eabi_attribute 20, 1 @ Tag_ABI_FP_denormal .eabi_attribute 21, 1 @ Tag_ABI_FP_exceptions .eabi_attribute 23, 3 @ Tag_ABI_FP_number_model .eabi_attribute 24, 1 @ Tag_ABI_align8_needed .eabi_attribute 25, 1 @ Tag_ABI_align8_preserved .eabi_attribute 26, 2 @ Tag_ABI_enum_size .eabi_attribute 30, 6 @ Tag_ABI_optimization_goals .eabi_attribute 34, 0 @ Tag_CPU_unaligned_access .eabi_attribute 18, 4 @ Tag_ABI_PCS_wchar_t There is then no .fpu directive to cause Tag_FP_arch to be set, because there are no functions containing code in the object file. If this object file is assembled by hand, but without -mfpu on the invocation of the assembler, then the build attributes produced will trigger an assertion during linking. Thinking about the build attributes, the combination of a single-precision only implementation of no floating-point architecture is still no floating-point architecture. Hence the assertion on the input BFD in the linker makes no real sense. We should, however, be more conservative in what we generate, so I've left the assertion on the output bfd in place; I don't think we can trigger it with this change since we never merge the problematic tags from a perversely generated input file. * elf32-arm.c (elf32_arm_merge_eabi_attributes): Remove assertion that the input bfd has Tag_FP_ARCH non-zero if Tag_ABI_HardFP_use is non-zero.

ld: Allow section groups to be resolved as part of a relocatable link This commit adds a new linker feature: the ability to resolve section groups as part of a relocatable link. Currently section groups are automatically resolved when performing a final link, and are carried through when performing a relocatable link. By carried through this means that one copy of each section group (from all the copies that might be found in all the input files) is placed into the output file. Sections that are part of a section group will not match input section specifiers within a linker script and are forcibly kept as separate sections. There is a slight resemblance between section groups and common section. Like section groups, common sections are carried through when performing a relocatable link, and resolved (allocated actual space) only at final link time. However, with common sections there is an ability to force the linker to allocate space for the common sections when performing a relocatable link, there's currently no such ability for section groups. This commit adds such a mechanism. This new facility can be accessed in two ways, first there's a command line switch --force-group-allocation, second, there's a new linker script command FORCE_GROUP_ALLOCATION. If one of these is used when performing a relocatable link then the linker will resolve the section groups as though it were performing a final link, the section group will be deleted, and the members of the group will be placed like normal input sections. If there are multiple copies of the group (from multiple input files) then only one copy of the group members will be placed, the duplicate copies will be discarded. Unlike common sections that have the --no-define-common command line flag, and INHIBIT_COMMON_ALLOCATION linker script command there is no way to prevent group resolution during a final link, this is because the ELF gABI specifically prohibits the presence of SHT_GROUP sections in a fully linked executable. However, the code as written should make adding such a feature trivial, setting the new resolve_section_groups flag to false during a final link should work as you'd expect. bfd/ChangeLog: * elf.c (_bfd_elf_make_section_from_shdr): Don't initially mark SEC_GROUP sections as SEC_EXCLUDE.

ELF/BFD: Hold the number of internal static relocs in `->reloc_count' Correct a commit e5713223cbc1 ("MIPS/BFD: For n64 hold the number of internal relocs in `->reloc_count'") regression and change internal relocation handling in the generic ELF BFD linker code such that, except in the presence of R_SPARC_OLO10 relocations, a section's `reloc_count' holds the number of internal rather than external relocations, making the handling more consistent between GAS, which sets `->reloc_count' with a call to `bfd_set_reloc', and LD, which sets `->reloc_count' as it reads input sections. The handling of dynamic relocations remains unchanged and they continue holding the number of external relocations in `->reloc_count'; they are also not converted to the internal form except in `elf_link_sort_relocs' (which does not handle the general, i.e. non-n64-MIPS case of composed relocations correctly as per the ELF gABI, though it does not seem to matter for the targets we currently support). The n64 MIPS backend is the only one with `int_rels_per_ext_rel' set to non-one, and consequently the change is trivial for all the remaining backends and targets. bfd/ * elf-bfd.h (RELOC_AGAINST_DISCARDED_SECTION): Subtract `count' from `reloc_count' rather than decrementing it. * elf.c (bfd_section_from_shdr): Multiply the adjustment to `reloc_count' by `int_rels_per_ext_rel'. * elf32-score.c (score_elf_final_link_relocate): Do not multiply `reloc_count' by `int_rels_per_ext_rel' for last relocation entry determination.

Use the ELF class to determine the word size for FreeBSD core notes. FreeBSD ELF cores contain data structures with that have two different layouts: one for ILP32 platforms and a second for LP64 platforms. Previously, the code used 'bits_per_word' from 'arch_info', but this field is not a reliable indicator of the format for FreeBSD MIPS cores in particular. I had originally posted this patch back in November because process cores for FreeBSD MIPS contained an e_flags value of 0 in the header which resulted in a bfd_arch which always had 'bits_per_word' set to 32. This permitted reading o32 cores, but not n64 cores. The feedback I received then was to try to change n64 cores to use a different default bfd_arch that had a 64-bit 'bits_per_word' when e_flags was zero. I submitted a patch to that effect but it was never approved. Instead, I changed FreeBSD's kernel and gcore commands to preserve the e_flags field from an executable when generating process cores. With a proper e_flags field in process cores, n64 cores now use a 64-bit bfd_arch and now work fine. However, the change to include e_flags in the process cores had the unintended side effect of breaking handling of o32 process cores. Specifically, FreeBSD MIPS builds o32 with a default MIPS architecture of 'mips3', thus FreeBSD process cores with a non-zero e_flags match the 'mips3' bfd_arch which has 64 'bits_per_word'. From this, it seems that 'bits_per_word' for FreeBSD MIPS is not likely to ever be completely correct. However, FreeBSD core dumps do reliably set the ELF class to ELFCLASS32 for cores using ILP32 and ELFCLASS64 for cores using LP64. As such, I think my original patch of using the ELF class instead of 'bits_per_word' is probably the simplest and most reliable approach for detecting the note structure layout. bfd/ChangeLog: * elf.c (elfcore_grok_freebsd_psinfo): Use ELF header class to determine structure sizes.

PPC64_OPT_LOCALENTRY ELFv2 functions with localentry:0 are those with a single entry point, ie. global entry == local entry, and that have no requirement on r2 or r12, and guarantee r2 is unchanged on return. Such an external function can be called via the PLT without saving r2 or restoring it on return, avoiding a common load-hit-store for small functions. The optimization is attractive. The TOC pointer load-hit-store is a major reason why calls to small functions that need no register saves, or with shrink-wrap, no register saves on a fast path, are slow on powerpc64le. To be safe, this optimization needs ld.so support to check that the run-time matches link-time function implementation. If a function in a shared library with st_other localentry non-zero is called without saving and restoring r2, r2 will be trashed on return, leading to segfaults. For that reason the optimization does not happen for weak functions since a weak definition is a fairly solid hint that the function will likely be overridden. I'm also not enabling the optimization by default unless glibc-2.26 is detected, which should have the ld.so checks implemented. bfd/ * elf64-ppc.c (struct ppc_link_hash_table): Add has_plt_localentry0.

MIPS/BFD: For n64 hold the number of internal relocs in `->reloc_count' Revert parts of commit fee24f1c5bfe ("objdump improvements for mips elf64"), <https://sourceware.org/ml/binutils/2003-03/msg00108.html>, and make the `->reloc_count' member of `struct bfd_section' hold the actual number of internal relocations stored in its `->relocation' vector. To do so adjust `mips_elf64_slurp_one_reloc_table' to set `->reloc_count' to the actual number of internal relocations retrieved and discard `mips_elf64_canonicalize_reloc', `mips_elf64_canonicalize_dynamic_reloc' and their corresponding target macros. Contrary to the description of `mips_elf64_slurp_one_reloc_table', adjusted appropriately, this makes generic relocation processing code happy and satisfies the "merge notes section" binutils test case. Add extra binutils test cases to expand the coverage of the generic "merge notes section" test case, now passing with the n64 ABI, across the MIPS o32, n32 and n64 ABIs regardless of the default ABI selected in target configuration, and also to verify correctness of the relocations produced. Conversely, do not provide any additional test cases for the original issue addressed with the commit referred: - objdump would display only 1/3 of the total number of relocations, because it used the external relocation count, but each external relocation is brought in as 3 internal relocations. as n64 ABI relocation processing with `objdump -r' and `objdump -R' is already widely covered across the GAS and LD test suites. bfd/ * elf64-mips.c (mips_elf64_canonicalize_reloc): Remove prototype and function.

MIPS16e2: Add MIPS16e2 ASE support Add MIPS16e2 ASE support as per the architecture specification[1], including in particular: 1. A new ELF ASE flag to mark MIPS16e2 binaries. 2. MIPS16e2 instruction assembly support, including a relaxation update to use LUI rather than an LI/SLL instruction pair for loading the high part of 32-bit addresses. 3. MIPS16e2 instruction disassembly support, including updated rules for extended forms of instructions that are now subdecoded and therefore do not alias to the original MIPS16 ISA revision instructions even for encodings that are not valid in the MIPS16e2 instruction set. Add `-mmips16e2' and `-mno-mips16e2' GAS command-line options and their corresponding `mips16e2' and `no-mips16e2' settings for the `.set' and `.module' pseudo-ops. Control the availability of the MT ASE subset of the MIPS16e2 instruction set with a combination of these controls and the preexisting MT ASE controls. Parts of this change by Matthew Fortune and Andrew Bennett.

x86-64: Improve PLT generation and synthetic PLT symbols On x86-64, the procedure linkage table (PLT) is used to 1. Call external function. 2. Call internal IFUNC function. The best implementation is selected for the target processor at run-time. 3. Act as the canonical function address. 4. Support LD_AUDIT to audit external function calls. 5. Support LD_PROFILE to profile external function calls. PLT looks like: PLT0: push GOT[1] jmp *GOT[2] nop PLT1: jmp *GOT[name1_index] push name1_reloc_index jmp PLT0 GOT is an array of addresses. Initially the GOT entry of name1 is filled with the address of the "push name1_reloc_index" instruction. The function, name1, is called via "jmp *GOT[name1]" in the PLT entry. Even when lazy binding is disabled by "-z now", the PLT0 entry may still be used with LD_AUDIT or LD_PROFILE if PLT entry is used for canonical function address. When linker is invoked with "-z bndplt", a different PLT layout in .plt is used: PLT0: push GOT[1] bnd jmp *GOT[2] nop PLT1: push name1_reloc_index bnd jmp PLT0 nop together with a second PLT section, .pl.bnd: PLT1: bnd jmp *GOT[name1_index] nop where the GOT entry of name1 is filled with the address of the push instruction of the corresponding entry in .plt. 1. With lazy binding, when the external function, name1, is called the first time, dynamic linker is called via PLT0 to update GOT[name1_index] with the actual address of name1 and transfers control to name1 afterwards. 2. PLT is also used to call a local IFUNC function, name1, run-time loader updates GOT[name1_index] when loading the module. This patch 1. Remove PLT layout configurations from x86-64 backend_data. 2. Add generic, lay and non-lazy PLT layout configurations to x86-64 link_hash_table. Generic PLT layout includes the PLT entry templates, information how to update the first instruction in PLT and PLT eh_frame informaton, which are initialized in x86-64 setup_gnu_properties, based on "-z bndplt" and target selection. PLT section alignment is also set to PLT entry size for non-NaCl target. 3. Remove elf_x86_64_create_dynamic_sections. create_dynamic_sections isn't always called, but GOT relocations need GOT relocations. Instead, create all x86-64 specific dynamic sections with alignment to their entry size in x86-64 setup_gnu_properties, which initializes elf.dynobj, so that x86-64 check_relocs can be simplified. 4. Rewrite elf_x86_64_get_synthetic_symtab to check PLT sections against all dynamic relocations to support both lazy and non-lazy PLTs. There is no change in PLT. The only externally visible change is the improvement of synthetic PLT symbols for .plt.got. bfd/ * elf64-x86-64.c (PLT_ENTRY_SIZE): Renamed to ... (LAZY_PLT_ENTRY_SIZE): This.

Fix PR21404 - assertion fail when calculating symbol size Fix a host of problems related to adjustment of symbol values and sizes when relaxing for avr. 1. Adjust symbol size first before adjusting symbol value. Otherwise, a symbol whose value just got adjusted to the relaxed address also ends up getting resized. See pr21404-1.s. 2. Reduce symbol sizes only if their span is below an alignment boundary. Otherwise, the size gets decremented once when the actual instruction is relaxed and padding bytes are added, and again when the padding bytes are deleted (if padding ends up being unnecessary). pr21404-2.s addresses that, and this bug is really the root cause of PR21404. 3. Adjust all symbol values before an alignment boundary. Previous code did not adjust symbol values if they fell in the would-be padded area, resulting in incorrect symbol values in some cases (see pr21404-3.s). 4. Increase symbol sizes if alignment directives require so. As pr21404-4.s shows .global nonzero_sym L1: jmp L1 nonzero_sym: nop nop .p2align 2 .size nonzero_sym, .-nonzero_sym The two nops satisfy the 4 byte alignment at assembly time and therefore the size of nonzero_sym is 4. Relaxation shortens the 4 byte jmp to a 2 byte rjmp, and to satisfy 4 byte alignment the code places 2 extra padding bytes after the nops, increasing nonzero_sym's size by 2. This wasn't handled before. If the assembly code does not have any align directives, then the boundary is the section size, and symbol values and sizes == boundary should also get adjusted. To handle that case, add a did_pad variable and use that to determine whether it should use < boundary or <= boundary. Also get rid of reloc_toaddr, which is now redundant. toaddr is now not adjusted to handle the above case - the newly added did_pad variable does the job. pr21404-{5,6,7,8} are the same testcases written for local symbols, as the code handles them slightly differently.

Nios2 dynobj handling fixes A number of places in elf32-nios.c created dynamic sections but didn't set the hash table dynobj. That meant we could have duplicate dynamic sections connected to a number of bfds, so size_dynamic_sections didn't properly discard or allocate contents. Also, the entire set of dynamic sections was created in check_relocs on seeing GOT relocs, when only .got related sections are needed, probably done to hide segfaults later in finish_dynamic_sections. The patch fixes these issues and makes the assembler emit errors when nios2 lacks the necessary pc-relative relocs for subtraction expressions, rather than silently generating bad code. eg. ld-elf/merge. I've also tidied uses of elf32_nios2_hash_table and elf_hash_table. bfd/ PR 20995 * elf32-nios2.c (nios2_elf32_relocate_section): Use htab rather than elf32_nios2_hash_table or elf_hash_table.

PowerPC addpcis fix This came up because I was looking at ld/tmpdir/addpcis.o and noticed the odd addends on REL16DX_HA. They ought to both be -4. The error crept in due REL16DX_HA howto being pc-relative (as indeed it should be), and code at gas/write.c:1001 after this comment /* Make it pc-relative. If the back-end code has not selected a pc-relative reloc, cancel the adjustment we do later on all pc-relative relocs. */ *not* cancelling the pc-relative adjustment. So I've made a dummy non-relative split reloc so that the generic code handles this, rather than attempting to add hacks later in md_apply_fix which would not be very robust. Having the new internal reloc also makes it easy to support addpcis rx,sym@ha as an equivalent to addpcis rx,(sym-0f)@ha 0: The patch also fixes overflow checking, which must test whether the addi will overflow too since @l relocs don't have any overflow check. Lastly, since I was poking at md_apply_fix, I arranged to have the generic gas/write.c code emit errors for subtraction expressions where we lack reloc support. include/ * elf/ppc64.h (R_PPC64_16DX_HA): New.

Don't make dynamic .data.rel.ro SEC_READONLY I'd made this dynamic section read-only so a flag test distinguished it from .dynbss, but like any other .data.rel.ro section it really should be marked read-write. (It is read-only after relocation, not before.) When using the standard linker scripts this usually doesn't matter since the output section is among other read-write sections and not page aligned. However, it might matter in the extraordinary case of the dynamic section being the only .data.rel.ro section with the output section just happening to be page aligned and a multiple of a page in size. In that case the output section would be read-only, and live it its own read-only PT_LOAD segment, which is incorrect. * elflink.c (_bfd_elf_create_dynamic_sections): Don't make dynamic .data.rel.ro read-only. * elf32-arm.c (elf32_arm_finish_dynamic_symbol): Compare section rather than section flags when deciding where copy reloc goes. * elf32-cris.c (elf_cris_finish_dynamic_symbol): Likewise. * elf32-hppa.c (elf32_hppa_finish_dynamic_symbol): Likewise. * elf32-i386.c (elf_i386_finish_dynamic_symbol): Likewise. * elf32-metag.c (elf_metag_finish_dynamic_symbol): Likewise. * elf32-microblaze.c (microblaze_elf_finish_dynamic_symbol): Likewise. * elf32-nios2.c (nios2_elf32_finish_dynamic_symbol): Likewise. * elf32-or1k.c (or1k_elf_finish_dynamic_symbol): Likewise. * elf32-ppc.c (ppc_elf_finish_dynamic_symbol): Likewise. * elf32-s390.c (elf_s390_finish_dynamic_symbol): Likewise. * elf32-tic6x.c (elf32_tic6x_finish_dynamic_symbol): Likewise. * elf32-tilepro.c (tilepro_elf_finish_dynamic_symbol): Likewise. * elf64-ppc.c (ppc64_elf_finish_dynamic_symbol): Likewise. * elf64-s390.c (elf_s390_finish_dynamic_symbol): Likewise. * elf64-x86-64.c (elf_x86_64_finish_dynamic_symbol): Likewise. * elfnn-aarch64.c (elfNN_aarch64_finish_dynamic_symbol): Likewise. * elfnn-riscv.c (riscv_elf_finish_dynamic_symbol): Likewise. * elfxx-mips.c (_bfd_mips_vxworks_finish_dynamic_symbol): Likewise. * elfxx-sparc.c (_bfd_sparc_elf_finish_dynamic_symbol): Likewise. * elfxx-tilegx.c (tilegx_elf_finish_dynamic_symbol): Likewise.

MIPS/BFD: Discard ineligible JALR relocations right away Discard R_MIPS_JALR and R_MICROMIPS_JALR relocations associated with jumps that cannot be converted to an equivalent branch right away in `mips_elf_calculate_relocation' rather than letting them through to `mips_elf_perform_relocation'. This includes cross-mode jumps which need to flip the ISA bit or jumps to a misaligned location that cannot be encoded with a branch, in addition to preemptible symbol references already handled. Cross-mode jumps are actually already rejected as the conversion is made in `mips_elf_perform_relocation', so in this case this change only saves some processing. Jumps to a misaligned location are however converted, with bits causing misalignment lost, making resulting code functionally different even if the lone effect is avoiding an address error exception with an instruction fetch at the jump destination requested. Add test cases suitable, also including GAS verification to confirm that the JALR relocations explicitly requested have indeed been output in the intermediate objects used. bfd/ * elfxx-mips.c (mips_elf_calculate_relocation) <R_MIPS_JALR> <R_MICROMIPS_JALR>: Discard relocation if `cross_mode_jump_p' or misaligned. gas/ * testsuite/gas/mips/jalr4.d: New test. * testsuite/gas/mips/jalr4-n32.d: New test. * testsuite/gas/mips/jalr4-n64.d: New test. * testsuite/gas/mips/jalr4.s: New test source. * testsuite/gas/mips/mips.exp: Run the new tests. ld/ * testsuite/ld-mips-elf/jalr4.dd: New test. * testsuite/ld-mips-elf/mips-elf.exp: Run the new test.

PR ld/20828: Move symbol version processing ahead of GC symbol sweep Complement commit b531344c34b0 ("PR ld/20828: Reorder the symbol sweep stage of section GC") and commit 81ff47b3a546 ("PR ld/20828: Fix linker script symbols wrongly forced local with section GC") and move symbol version processing ahead of the symbol sweep stage of section GC, all in `bfd_elf_size_dynamic_sections', so that version symbols created stay in the global scope and are not output as local symbols to the dynamic symbol table in the presence of corresponding symbol definitions pulled from a DSO involved in a link. Consolidate the whole of symbol version processing into a single block from all parts scattered across the function and rearranging the local variables used as necessary, however leaving the setting of dynamic entries associated with the DT_VERDEF, DT_VERDEFNUM, DT_VERNEED and DT_VERNEEDNUM tags and the SEC_EXCLUDE flag for unused `.gnu.version' section in the original places.

bfd/dwarf: Improve use of previously loaded dwarf information When parsing DWARF data in order to report file/line type error messages we perform section placement to make section addresses unique within relocatable object files. Currently, if we reuse previously loaded (and cached) dwarf data then we neglect to perform section placement, the result is that the section addresses will not be unique, and we might, incorrectly associate an address with the wrong debug information, and so report an incorrect file and line number. Further we neglect to check that that bfd for which we are looking up debug information is actually the bfd for which the previous debug information was loaded, it is possible that we will reuse previously loaded debug information for a different bfd. And finally, due to following of gnu_debuglink links in one bfd to another, the process of checking that the cached debug information is valid requires us to track the original bfd in the cached debug information. The original debug information here is either the bfd that we're interested in, not the bfd we finally load the debug information from. bfd/ChangeLog: * dwarf2.c (struct dwarf2_debug): Add orig_bfd member.

PowerPC/BFD: Convert `%P: %H:' to `%H:' in error messages Remove an inconsistency in BFD linker error messages across the PowerPC backends, where in the presence of line information the `%P: %H:' format sequence makes the first error message produced for any given function different from subsequent ones. Taking the `ld/testsuite/ld-powerpc/tocopt7.s' test case source as an example and the `powerpc-linux' target we have: $ as -gdwarf2 -o tocopt.o -a64 tocopt.s $ ld -o tocopt -melf64ppc tocopt.o ld: tocopt.o: In function `_start': tocopt.s:35:(.text+0x14): toc optimization is not supported for 0x3fa00000 instruction. ld: tocopt.s:49:(.text+0x34): toc optimization is not supported for 0x3fa00000 instruction. $ where the first error message does not have the source file name prefixed with the linker program executable's name, i.e. `ld:', whereas the second error message does, as would any subsequent. This is because with a multiple-line error message such as `%H' produces `%P' only prints the program executable's name on the first line and not any later ones. Also the PowerPC backend is the only part of BFD which uses `%P' along with one of the clever `%C', `%D', `%G', `%H' format specifiers. And last but not least this breaks a GNU Coding Standard's requirement that error messages from compilers should look like this: source-file-name:lineno: message also quoted in `vfinfo' code handling these specifiers. Convert `%P: %H:' to `%H:' in error messages across the PowerPC backends then, yielding: $ as -gdwarf2 -o tocopt.o -a64 tocopt.s $ ld -o tocopt -melf64ppc tocopt.o tocopt.o: In function `_start': tocopt.s:35:(.text+0x14): toc optimization is not supported for 0x3fa00000 instruction. tocopt.s:49:(.text+0x34): toc optimization is not supported for 0x3fa00000 instruction. $ instead, making it consistent and matching the GNU Coding Standard's requirement. bfd/ * elf32-ppc.c (ppc_elf_check_relocs): Use `%H:' rather than `%P: %H:' with `info->callbacks->einfo'.

PR ld/20828: Reorder the symbol sweep stage of section GC Complement commit 81ff47b3a546 ("PR ld/20828: Fix linker script symbols wrongly forced local with section GC") and move the symbol sweep stage of section GC from `elf_gc_sweep' to `bfd_elf_size_dynamic_sections', avoiding the need to clear the `forced_local' marker, problematic for targets that have special processing in their `elf_backend_hide_symbol' handler. Set `mark' instead in `bfd_elf_record_link_assignment' and, matching changes from commit 3bd43ebcb602 ("ld --gc-sections fail with __tls_get_addr_opt"), also in PowerPC `__tls_get_addr_opt' handling code, removing a: FAIL: PR ld/20828 dynamic symbols with section GC (version script) test suite failure with the `score-elf' target. The rationale is it is enough if symbols are swept at the beginning of `bfd_elf_size_dynamic_sections' as it is only in this function that the size of the GOT, the dynamic symbol table and other dynamic sections is determined, which will depend on the number of symbols making it to the dynamic symbol table. It is also appropriate to do the sweep at this point as it is already after any changes have been made to symbols with `bfd_elf_record_link_assignment', and not possible any earlier as calls to that function are only made just beforehand -- barring audit entry processing -- via `gld${EMULATION_NAME}_find_statement_assignment' invoked from `gld${EMULATION_NAME}_before_allocation' which is the ELF handler for `ldemul_before_allocation'. bfd/ PR ld/20828 * elflink.c (bfd_elf_record_link_assignment): Revert last change and don't ever clear `forced_local'.

PowerPC dynamic relocations This patch fixes a number of issues with powerpc dynamic relocations. 1) Both ppc and ppc64 were emitting more dynamic symbols and relocations than necessary, due to not supporting static linker resolution of tls_index entries for __tls_get_addr_opt. This meant that any @got@tlsgd or @got@tlsld reloc needed to make their symbols dynamic and generate dptmod and dtprel relocs for the dynamic linker. That would have been passable, but what happened was that practically all @got relocations resulted in their symbols being made dynamic and dynamic relocations emitted against the GOT entries. (Mostly visible on ppc32 executables since ppc64 gcc really only uses @got style relocs for TLS.) 2) The PowerOpen syntax was not supported with __tls_get_addr_opt. DTPMOD/DTPREL relocs on tls_index TOC entries did not use the trick of forcing dynamic symbols and relocations so those entries always resulted in the full __tls_get_addr processing. gcc doesn't use the PowerOpen syntax for TLS, and normally such code would be optimized to TLS IE or LE so the impact of missing this support was minimal. 3) In an executable, relocations against GNU indirect functions always used the value of their PLT stub. While this is correct, it is better in some cases to use a dynamic relocation. An extra dynamic relocation can mean that calls via function pointers need not bounce through the PLT stub at runtime. The patch also tidies the PLT handling code in ppc32 allocate_dynrelocs. Allocating PLT entries after other dynamic relocs allows the PLT loop to omit special handling for undefined weak symbols, and that in turn allows the loop to be simplified. bfd/ * elf32-ppc.c (ppc_elf_adjust_dynamic_symbol): Merge two cases where dynamic relocs are preferable.

PR ld/20828: Fix linker script symbols wrongly forced local with section GC Fix a generic ELF linker regression introduced with a chain of changes made to unused input section garbage collection: - commit 1a766c6843ce ("Also hide symbols without PLT nor GOT references."), <https://sourceware.org/ml/binutils/2011-09/msg00076.html>, - commit 1d5316ab67e1 ("PR ld/13177: garbage collector retains zombie references to external libraries"), <https://sourceware.org/ml/binutils/2011-10/msg00161.html>, - commit 6673f753c019 ("Fix PR 12772, garbage collection of dynamic syms"), <https://sourceware.org/ml/binutils/2011-12/msg00077.html>, causing the garbage collection of unused symbols present in a DSO involved in a link to make identically named symbols ordinarily defined (i.e. not hidden or PROVIDEd) by a linker script local, even though the latter symbols are supposed to be global as if no DSO defined them as well. This is because linker script assignments are processed very late as `lang_process' proceeds, down in the call to `ldemul_before_allocation', which is made after the call to `lang_gc_sections' to do input section garbage collecting. Consequently if unused, then any such DSO-defined symbol has already been garbage-collected and internally marked local. It would ordinarily be removed from dynamic symbol table output, however a linker script assignment correctly replaces its original definition with the new one and enters it into the dynamic symbol table produced as it is supposed to be exported. The original local marking is however retained making the symbol local in the dynamic symbol table and therefore not available externally. This also causes a sorting problem with the MIPS target, which does not expect non-section local dynamic symbols to be output and produces an invalid binary. Fix the problem then, by removing the `forced_local' marking for the offending case and add suitable test cases. First to verify that unused symbols ordinarily defined with linker script assignments remain exported in the context of input section garbage collection whether or not a DSO defining identically named symbols is present in the link. Second that a linker version script still correctly retains or removes such symbols as requested. bfd/ PR ld/20828 * elflink.c (bfd_elf_record_link_assignment): Clear any `forced_local' marking for DSO symbols that are not being provided. ld/ PR ld/20828 * testsuite/ld-elf/pr20828-1.sd: New test. * testsuite/ld-elf/pr20828-2a.sd: New test. * testsuite/ld-elf/pr20828-2b.sd: New test. * testsuite/ld-elf/pr20828.ld: New test linker script. * testsuite/ld-elf/pr20828.ver: New test version script. * testsuite/ld-elf/pr20828.s: New test source. * testsuite/ld-elf/shared.exp: Run the new test.
