All of the backend relocate_section functions that interpret reloc numbers assuming the input file is of the expected type (ie. same as output or very similar) really ought to be checking input file type.

2018-12-14elf: Add PT_GNU_PROPERTY segment typeH.J. Lu3-7/+39
Linkers group input note sections with the same name into one output note section with the same name. One output note section is placed in one PT_NOTE segment. New linkers merge all input .note.gnu.property sections into one output .note.gnu.property section with a single NT_GNU_PROPERTY_TYPE_0 note in a single PT_NOTE segment. Since older linkers treat input .note.gnu.property section as a generic note section and just concatenate all input .note.gnu.property sections into one output .note.gnu.property section without merging them, we may see one or more NT_GNU_PROPERTY_TYPE_0 notes in PT_NOTE segment, which are invalid. GNU_PROPERTY_X86_UINT32_VALID was defined to address this issue such that linker sets the bit for non-relocatable outputs. But it isn't sufficient: 1. It doesn't cover generic properties. 2. When -mx86-used-note=yes is passed to x86 assembler, the GNU_PROPERTY_X86_UINT32_VALID bit is set in GNU_PROPERTY_X86_ISA_1_USED property in object file and older linkers generate invalid NT_GNU_PROPERTY_TYPE_0 notes with the GNU_PROPERTY_X86_UINT32_VALID bit set. I am proposing the following changes: 1. Add PT_GNU_PROPERTY segment type: # define PT_GNU_PROPERTY (PT_LOOS + 0x474e553) which covers .note.gnu.property section. 2. Remove GNU_PROPERTY_X86_UINT32_VALID. bfd/ PR ld/23900 * elf.c (get_program_header_size): Add a PT_GNU_PROPERTY segment for NOTE_GNU_PROPERTY_SECTION_NAME.

2018-12-06PowerPC @l, @h and @ha warnings, plus VLE e_liAlan Modra2-8/+27
This patch started off just adding the warnings in tc-ppc.c about incorrect usage of @l, @h and @ha in instructions that don't have 16-bit D-form fields. That unfortunately showed up three warnings in ld/testsuite/ld-powerpc/vle-multiseg.s on instructions like e_li r3, IV_table@l+0x00 which was being assembled to 8: 70 60 00 00 e_li r3,0 a: R_PPC_ADDR16_LO IV_table The ADDR16_LO reloc is of course completely bogus on e_li, which has a split 20-bit signed integer field in bits 0x1f7fff, the low 11 bit in 0x7ff, the next 5 bits in 0x1f0000, and the high 4 bits in 0x7800. Applying an ADDR16_LO reloc to the instruction potentially changes the e_li instruction to e_add2i., e_add2is, e_cmp16i, e_mull2i, e_cmpl16i, e_cmph16i, e_cmphl16i, e_or2i, e_and2i., e_or2is, e_lis, e_and2is, or some invalid encodings. Now there is a relocation that suits e_li, R_PPC_VLE_ADDR20, which was added 2017-09-05 but I can't see code in gas to generate the relocation. In any case, VLE_ADDR20 probably doesn't have the correct semantics for @l since ideally you'd want an @l to pair with @h or @ha to generate a 32-bit constant. Thus @l should only produce a 16-bit value, I think. So we need some more relocations to handle e_li it seems, or as I do in this patch, modify the behaviour of existing relocations when applied to e_li instructions. include/ * opcode/ppc.h (E_OPCODE_MASK, E_LI_MASK, E_LI_INSN): Define. bfd/ * elf32-ppc.c (ppc_elf_howto_raw <R_PPC_VLE_ADDR20>): Correct mask and shift value.

2018-12-05[aarch64] Add support for pointer authentication B keySam Tebbs2-0/+6
Armv8.3-A has another key used in pointer authentication called the B-key (other than the A-key that is already supported). In order for stack unwinders to work it is necessary to be able to identify frames that have been signed with the B-key rather than the A-key and it was felt that keeping this as an augmentation character in the CIE was the best bet. The DWARF extensions for ARM therefore propose to add a new augmentation character 'B' to the CIE augmentation string and the corresponding cfi directive ".cfi_b_key_frame". I've made the relevant changes to GAS and LD to add support for B-key unwinding, which required modifying LD to check for 'B' in the augmentation string, adding the ".cfi_b_key_frame" directive to GAS and adding a "pauth_key" field to GAS's fde_entry and cie_entry structs. The pointer authentication instructions will behave as NOPs on architectures that don't support them, and so a check for the architecture being assembled for is not necessary since there will be no behavioural difference between augmentation strings with and without the 'B' character on such architectures. 2018-12-05 Sam Tebbs <sam.tebbs@arm.com> bfd/ * elf-eh-frame.c (_bfd_elf_parse_eh_frame): Add check for 'B'. gas/ * dw2gencfi.c (struct cie_entry): Add tc_cie_entry_extras invocation.

2018-12-01x86: Delay setting the iplt section alignmentH.J. Lu3-7/+35
Delay setting its alignment until we know it is non-empty. Otherwise an empty iplt section may change vma and lma of the following sections, which triggers moving dot of the following section backwards, resulting in a warning and section lma not being set properly. It later leads to a "File truncated" error. bfd/ PR ld/23930 * elfxx-x86.c (_bfd_x86_elf_size_dynamic_sections): Update the iplt section alignment if it is non-empty.
