2018-05-04-Wstringop-truncation warningsAlan Modra11-51/+70
This patch is aimed at silencing gcc8 -Wstringop-truncation warnings. Unfortunately adding __attribute__ ((__nonstring)) doesn't work in a number of the places patched here, (see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85643) so if you have recent glibc headers installed you'll need to configure binutils with --disable-werror to compile using gcc8 or gcc9. include/ * ansidecl.h: Import from gcc. * coff/internal.h (struct internal_scnhdr): Add ATTRIBUTE_NONSTRING to s_name.

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.

2018-04-26PPC64: always make synthetic .text symbols for GNU ifunc symbolsPedro Alves2-6/+21
If you create an ifunc using GCC's __attribute__ ifunc, like: extern int gnu_ifunc (int arg); static int gnu_ifunc_target (int arg) { return 0; } __typeof (gnu_ifunc) *gnu_ifunc_resolver (unsigned long hwcap) { return gnu_ifunc_target; } __typeof (gnu_ifunc) gnu_ifunc __attribute__ ((ifunc ("gnu_ifunc_resolver"))); then you end up with two (function descriptor) symbols, one for the ifunc itself, and another for the resolver: (...) 12: 0000000000020060 104 FUNC GLOBAL DEFAULT 18 gnu_ifunc_resolver (...) 16: 0000000000020060 104 GNU_IFUNC GLOBAL DEFAULT 18 gnu_ifunc (...) Both ifunc and resolver symbols have the same address/value, so ppc64_elf_get_synthetic_symtab only creates a synthetic text symbol for one of them. In the case above, it ends up being created for the resolver, only: (gdb) maint print msymbols (...) [ 7] t 0x980 .frame_dummy section .text [ 8] T 0x9e4 .gnu_ifunc_resolver section .text [ 9] T 0xa58 __glink_PLTresolve section .text (...) GDB needs to know when a program stepped into an ifunc resolver, so that it can know whether to step past the resolver into the target function without the user noticing. The way GDB does it is my checking whether the current PC points to an ifunc symbol (since resolver and ifunc have the same address by design). The problem is then that ppc64_elf_get_synthetic_symtab never creates the synchetic symbol for the ifunc, so GDB stops stepping at the resolver (in a test added by the following patch): (gdb) step gnu_ifunc_resolver (hwcap=21) at gdb/testsuite/gdb.base/gnu-ifunc-lib.c:33 33 { (gdb) FAIL: gdb.base/gnu-ifunc.exp: resolver_attr=1: resolver_debug=1: final_debug=0: step After this commit, we get: [ 8] i 0x9e4 .gnu_ifunc section .text [ 9] T 0x9e4 .gnu_ifunc_resolver section .text And stepping an ifunc call takes to the final function: (gdb) step 0x00000000100009e8 in .final () (gdb) PASS: gdb.base/gnu-ifunc.exp: resolver_attr=1: resolver_debug=1: final_debug=0: step An alternative to touching bfd I considered was for GDB to check whether there's an ifunc data symbol / function descriptor that points to the current PC, whenever the program stops, but discarded it because we'd have to do a linear scan over .opd over an over to find a matching function descriptor for the current PC. At that point I considered caching that info, but quickly dismissed it as then that has no advantage (memory or performance) over just creating the synthetic ifunc text symbol in the first place. I ran the binutils and ld testsuites on PPC64 ELFv1 (machine gcc110 on the GCC compile farm), and saw no regressions. This commit is part of a GDB patch series that includes GDB tests that fail without this fix. bfd/ChangeLog: 2018-04-26 Pedro Alves <palves@redhat.com> * elf64-ppc.c (ppc64_elf_get_synthetic_symtab): Don't consider ifunc and non-ifunc symbols duplicates.

2018-04-20PR22978, TLS local-dynamic incorrectly linked on hppa-linuxAlan Modra2-32/+48
We were emitting dynamic relocs on the second word of a TLS GD GOT entry pair (the dtprel offset), without the addend necessary when no symbol is present on the dynamic reloc. Unfortunately the simple solution of providing the proper addend doesn't work due to an hppa glibc ld.so bug that ignores such addends. So instead optimize the relocs. The dtprel offset is known at link time for locally defined symbols (the only case where we'll end up with no symbol on a dynamic reloc) so we can omit the dynamic reloc in that case. Furthermore, we can omit a dynamic reloc on the first word of a TLS GD GOT entry pair (the module id) if the symbol is local and we are producing an executable. Similarly, a tprel reloc on a TLS IE GOT entry is not needed for local symbols in an executable. So the condition for TLS GOT relocs can become bfd_link_dll(info) rather than bfd_link_pic(info) as needed for normal GOT relocs. This all presumes hppa ld.so doesn't need to differentiate TLS GD GOT pairs from TLS LD GOT pairs, which is currently true. PR 22978 * elf32-hppa.c (got_relocs_needed): Add extra param to special case both dtprel and tprel relocs. (allocate_dynrelocs): Adjust conditions for got relocs. (elf32_hppa_relocate_section): Likewise for local sym got relocs. Emit dynamic relocs on TLS GOT entries for shared libraries, not when pic. Omit dynamic reloc on dtprel entry when local, and on tprel entry when local and executable.
