2016-12-29link_hash_copy_indirect and symbol flagsAlan Modra11-47/+63
A while ago HJ fixed PR ld/18720 with commit 6e33951ed, which, among other things, modified _bfd_elf_link_hash_copy_indirect to not copy ref_dynamic, ref_regular, ref_regular_nonweak, non_got_ref, needs_plt and pointer_equality_needed when setting up an indirect non-versioned symbol pointing to a non-default versioned symbol. I didn't notice at the time, but the pr18720 testcase fails on hppa-linux with "internal error, aborting at binutils-gdb-2.28/bfd/elf32-hppa.c:3933 in elf32_hppa_relocate_section". Now hppa-linux creates entries in the plt even for local functions, if they are referenced using plabel (function pointer) relocations. So needs_plt is set for foo when processing pr18720a.o. When the aliases in pr28720b.o are processed, we get an indirection from foo to foo@FOO, but don't copy needs_plt. Since foo@FOO is the "real" symbol that is used after that point, no plt entry is made for foo and we bomb when relocating the plabel. As shown by the hppa-linux scenario, needs_plt should be copied even for non-default versioned symbols. I believe all of the others ought to be copied too, with the exception of ref_dynamic. Not copying ref_dynamic is right because if a shared lib references "foo" it should not be satisfied by any non-default version "foo@FOO". * elflink.c (_bfd_elf_link_hash_copy_indirect): Only omit copying one flag, ref_dynamic, when versioned_hidden. * elf64-ppc.c (ppc64_elf_copy_indirect_symbol): Likewise. * elf32-hppa.c (elf32_hppa_copy_indirect_symbol): Use same logic for copying weakdef flags.

2016-12-26dynrelro section for read-only dynamic symbols copied into executableAlan Modra29-154/+521
Variables defined in shared libraries are copied into an executable's .bss section when code in the executable is non-PIC and thus would require dynamic text relocations to access the variable directly in the shared library. Recent x86 toolchains also copy variables into the executable to gain a small speed improvement. The problem is that if the variable was originally read-only, the copy in .bss is writable, potentially opening a security hole. This patch cures that problem by putting the copy in a section that becomes read-only after ld.so relocation, provided -z relro is in force. The patch also fixes a microblaze linker segfault on attempting to use dynamic bss variables. bfd/ PR ld/20995 * elf-bfd.h (struct elf_link_hash_table): Add sdynrelro and sreldynrelro.

2016-12-20Re-work RISC-V gas flags: now we just support -mabi and -marchAndrew Waterman2-2/+7
We've decided to standardize on two flags for RISC-V: "-march" sets the target architecture (which determines which instructions can be generated), and "-mabi" sets the target ABI. We needed to rework this because the old flag set didn't support soft-float or single-float ABIs, and didn't support an x32-style ABI on RISC-V. Additionally, we've changed the behavior of the -march flag: it's now a lot stricter and only parses things we can actually understand. Additionally, it's now lowercase-only: the rationale is that while the RISC-V ISA manual specifies that ISA strings are case-insensitive, in Linux-land things are usually case-sensitive. Since this flag can be used to determine library paths, we didn't want to bake some case-insensitivity in there that would case trouble later. This patch implements these two new flags and removes the old flags that could conflict with these. There wasn't a RISC-V release before, so we want to just support a clean flag set. include/ * elf/riscv.h (EF_RISCV_SOFT_FLOAT): Don't define. (EF_RISCV_FLOAT_ABI, EF_RISCV_FLOAT_ABI_SOFT): Define.

Before this commit we didn't cleanly support CFI directives because the internal offsets used to get relaxed which broke them. This patch significantly reworks how we handle linker relaxations: * DWARF is now properly supported * There is a ".option norelax" to disable relaxations, for when users write assembly that can't be relaxed (if it's to be later patched up, for example). * There is an additional _RELAX relocation that specifies when previous relocations can be relaxed. We're in the process of documenting the RISC-V ELF ABI, which will include documentation of our relocations https://github.com/riscv/riscv-elf-psabi-doc/blob/master/riscv-elf.md but we expect that this relocation set will remain ABI compatible in the future (ie, it's safe to release).

2016-12-14MIPS/opcodes: Also set disassembler's ASE flags from ELF structuresMaciej W. Rozycki4-0/+25
Respect any ASE flags recorded in ELF file structures for the purpose of selecting instructions to be disassembled, preventing code from being hex-dumped even though having been clearly indicated as valid at the assembly time. Use date from the MIPS ABI flags structure if present, and otherwise there may be an MDMX ASE flag set in the ELF file header. For backwards compatibility only set extra flags and do not clear any, preserving all previously set by the architecture selected to be disassembled for. include/ * elf/mips.h (Elf_Internal_ABIFlags_v0): Also declare struct typedef as `elf_internal_abiflags_v0'. bfd/ * bfd-in.h (elf_internal_abiflags_v0): New struct declaration.

2016-12-14ld: aarch64: fix TLS relaxation where TCB_SIZE is usedYury Norov2-5/+20
TCB_SIZE is 2*sizeof(void *), which is 0x10 for lp64, and 0x8 for ilp32. During relaxation, ld goes to do a replace: bl __tls_get_addr => add R0, R0, TCB_SIZE But actual implementation is: bfd_putl32 (0x91004000, contents + rel->r_offset + 4); Which is equivalent of add x0, x0, 0x10. This is wrong for ilp32. The possible fix for it is: bfd_putl32 (0x91000000 | (TCB_SIZE<<10), contents + rel->r_offset + 4); But ilp32 also needs w-registers, so it's simpler to put proper instruction in #if/#else condition. There are 2 such relaxations in elfNN_aarch64_tls_relax(), and so 2 new tests added for ilp32 mode to test it.

2016-12-13Don't add PHDR for objcopy/strip or ld script specifying PHDRSAlan Modra2-23/+19
HPPA64 needs to add a DT_PHDR header for shared libs. That's fine when linking but shouldn't happen for strip/objcopy. Also PHDR must come first so there's no need to look at all program headers. bfd/ * elf64-hppa.c (elf64_hppa_modify_segment_map): Don't add PHDR for objcopy/strip or when a ld script specifies PHDRS. ld/ * testsuite/ld-elf/nobits-1.d: Remove xfail for hppa64. * testsuite/ld-elf/note-1.d: Likewise. * testsuite/ld-elf/note-2.d: Likewise.
2016-12-13Don't fudge p_vaddr when PHDR in segmentAlan Modra2-1/+20
RX does horrible fudges to PT_LOAD p_vaddr, that affect the testsuite and mean the target won't support dynamic objects. The latter probably doesn't matter too much since RX is an embedded target, but it's easy to stop some of the fudges in order to reduce special cases for RX in the testsuite. The changes make sense in isolation too. bfd/ * elf32-rx.c (elf32_rx_modify_program_headers): Don't adjust segments that include the ELF file header or program headers. ld/ * testsuite/ld-elf/flags1.d: Run for RX. * testsuite/ld-scripts/phdrs.exp: Likewise. * testsuite/ld-scripts/pr14962.d: Likewise. * testsuite/ld-scripts/pr14962-2.d: Likewise.
