2018-05-21ld: Hide symbols defined by HIDDEN/PROVIDE_HIDDENH.J. Lu30-6/+148
There should be no difference in output for symbols defined by HIDDEN or PROVIDE_HIDDEN assignments whether they are explicitly marked as hidden or not.

2018-05-18x86: Don't set eh->local_ref to 1 for linker defined symbolsH.J. Lu3-60/+13
Since symbols created by HIDDEN and PROVIDE_HIDDEN assignments in linker script may be marked as defined, but not hidden, we can't set eh->local_ref to 1 in _bfd_x86_elf_link_symbol_references_local. Also R_386_GOT32X should be handled as just like R_386_GOT32 when relocating a section. The input R_386_GOT32X relocations, which can be relaxed, should have been converted to R_386_PC32, R_386_32 or R_386_GOTOFF. bfd/ PR ld/23189 * elf32-i386.c (elf_i386_relocate_section): Handle R_386_GOT32X like R_386_GOT32. * elfxx-x86.c (_bfd_x86_elf_link_symbol_references_local): Don't set eh->local_ref to 1 for linker defined symbols. ld/ PR ld/23189 * testsuite/ld-i386/i386.exp: Run pr23189. * testsuite/ld-x86-64/x86-64.exp: Likewise. * testsuite/ld-i386/pr23189.d: New file. * testsuite/ld-i386/pr23189.s: Likewise. * testsuite/ld-i386/pr23189.t: Likewise. * testsuite/ld-x86-64/pr23189.d: Likewise. * testsuite/ld-x86-64/pr23189.s: Likewise. * testsuite/ld-x86-64/pr23189.t: Likewise.

2018-05-16PR22458, failure to choose a matching ELF targetAlan Modra7-32/+44
https://sourceware.org/ml/binutils/2013-05/msg00271.html was supposed to banish "file format is ambiguous" errors for ELF. It didn't, because the code supposedly detecting formats that implement match_priority didn't work. That was due to not placing all matching targets into the vector of matching targets. ELF objects should all match the generic ELF target (priority 2), plus one or more machine specific targets (priority 1), and perhaps a single machine specific target with OS/ABI set (priority 0, best match). So the armel object in the testcase actually matches elf32-littlearm, elf32-littlearm-symbian, and elf32-littlearm-vxworks (all priority 1), and elf32-little (priority 2). As the PR reported, elf32-little wasn't seen as matching. Fixing that part of the problem wasn't too difficult but matching the generic ELF target as well as the ARM ELF targets resulted in ARM testsuite failures. These proved to be the annoying reordering of stubs that occurs from time to time due to the stub names containing the section id. Matching another target causes more sections to be created in elf_object_p. If section ids change, stub names change, which results in different hashing and can therefore result in different hash table traversal and stub creation order. That particular problem is fixed by resetting section_id to the initial state before attempting each target match, and taking a snapshot of its value after a successful match.

2018-05-12PR20659, Objcopy and change section lma failingAlan Modra2-86/+84
Sections may well belong in multiple segments. The testcase in the PR saw an allocated section being assigned to an ABIFLAGS segment, then not being assigned to a LOAD segment because it had already been handled. To fix that particular problem this patch sets and tests segment_mark only for LOAD segments. I kept the segment_mark test for LOAD segments because I think there may otherwise be a problem with zero size sections. A few other problems showed up with the testcase. Some targets align .dynamic, resulting in the test failing with "section .dynamic lma 0x800000c0 adjusted to 0x800000cc" and similar messages. I've tried to handle that with some more hacks to the segment lma, which do the right thing for the testcase, but may well fail in other situations. I've also removed the tests of segment lma (p_paddr) and code involved in deciding that an adjusted segment no longer covers the file or program headers. Those test can't be correct in the face of objcopy --change-section-lma. It may be necessary to reinstate the tests but do them modulo page size, but we'll see how this goes.

2018-05-09Fix binary compatibility between GCC and the TI compiler for the PRU target.Dimitar Dimitrov2-19/+158
My original implementation for LDI32 pseudo does not conform to the TI ABI. I wrongly documented my TI PRU ELF object files inspection, which got propagated into my binutils implementation. Issue was exposed when running the GCC ABI testsuite against TI toolchain. According to TI ABI, LDI32 must use first LDI instruction to load the MSB 16bits, and second LDI instruction for the LSB 16bits. This patch will break binary compatibility with previously released binutils versions for PRU. Still, I think it is better to fix binutils to conform to the chip vendor ABI. bfd * elf32-pru.c (pru_elf32_do_ldi32_relocate): Make LDI32 relocation conformant to TI ABI.

2018-05-03BFD: Prevent writing the MIPS _gp_disp symbol into symbol tablesSimon Atanasyan3-12/+20
The _gp_disp is a magic symbol, always implicitly defined by the linker. It does not make a sense to write it into symbol tables for output files. Moreover, now if the linker gets a version script, the _gp_disp symbol gets zero version definition index. The zero index means[1]: "The symbol is local, not available outside the object." But the _gp_disp symbol has GLOBAL binding. That confuses some tools like for example the LLD linker when they get such files as inputs. This patch fixes the problem - it prevents writing the _gp_disp symbol in regular and dynamic symbol tables. This was tested by running LD test suite on a mipsel-linux board.
