2016-06-28[AArch64] Make register indices be full 64-bit valuesRichard Sandiford7-5/+103
aarch64_opnd_info used bitfields to hold vector element indices, but values were stored into those bitfields before their ranges had been checked. This meant large invalid indices could be silently truncated to smaller valid indices. The two obvious fixes were to do the range checking earlier or use a full 64-bit field for the index. I went for the latter for two reasons: - Doing the range checking in operand_general_constraint_met_p seems structurally cleaner than doing it while parsing. - The bitfields didn't really buy us anything. The imm field of the union is already 128 bits, so we can use a full int64_t index without growing the structure. The patch also adds missing range checks for the elements in a register list index. include/ * opcode/aarch64.h (aarch64_opnd_info): Change index fields to int64_t. opcodes/ * aarch64-opc.c (operand_general_constraint_met_p): Check the range of ldst_elemlist operands.

2016-06-27Fix use of a dangling pointer for Python breakpoint objectsPierre-Marie de Rodat6-0/+127
When a Python script tries to create a breakpoint but fails to do so, gdb.Breakpoint.__init__ raises an exception and the breakpoint does not exist anymore in the Python interpreter. However, GDB still keeps a reference to the Python object to be used for a later hook, which is wrong. This commit adds the necessary cleanup code so that there is no stale reference to this Python object. It also adds a new testcase to reproduce the bug and check the fix. 2016-06-25 Pierre-Marie de Rodat <derodat@adacore.com> gdb/ * python/py-breakpoint.c (bppy_init): Clear bppy_pending_object when there is an error during the breakpoint creation. gdb/testsuite * gdb.python/py-breakpoint-create-fail.c, gdb.python/py-breakpoint-create-fail.exp, gdb.python/py-breakpoint-create-fail.py: New testcase.

2016-06-25MIPS16/GAS: Restore unsupported relocation diagnosticsMaciej W. Rozycki77-63/+1227
Correct a MIPS16 relocation handling regression in GAS introduced with: commit 177b4a6ad0047c8995fbc55016bc4f4b68d53b4a Author: Alexandre Oliva <aoliva@redhat.com> Date: Mon Mar 18 18:56:18 2002 +0000 discussed at <https://sourceware.org/ml/binutils/2002-03/msg00345.html>, which removed a preparatory call to `mips16_extended_frag' previously made from `md_estimate_size_before_relax'. As a result the function is never called with its `sec' parameter non-NULL and consequently all the unsupported relocation checks within are dead and never trigger, causing any unhandled relocations to silently resolve to 0. Unfortunately there was no sufficient test suite coverage back then to catch this. Remove all dead code then, and all the associated comments. Update the remaining call to `mips16_extended_frag' from `mips_relax_frag' to pass the relocation section as the `sec' parameter and use it to mark frags which require an external relocation, as extended. Finally handle any outstanding MIPS16 relocations in `md_convert_frag' and report an error since we don't support any except with percent operators. gas/ * config/tc-mips.c (append_insn): Use any `O_symbol' expression unchanged with relaxed MIPS16 instructions.

2016-06-24Add support for catching system calls to native FreeBSD targets.John Baldwin8-1/+523
All platforms on FreeBSD use a shared system call table, so use a single XML file to describe the system calls available on each FreeBSD platform. Recent versions of FreeBSD include the identifier of the current system call when reporting a system call entry or exit event in the ptrace_lwpinfo structure obtained via PT_LWPINFO in fbsd_wait. As such, FreeBSD native targets do not use the gdbarch method to fetch the system call code. In addition, FreeBSD register sets fetched via ptrace do not include an equivalent of 'orig_rax' (on amd64 for example), so the system call code cannot be extracted from the available registers during a system call exit. However, GDB assumes that system call catch points are not supported if the gdbarch method is not present. As a workaround, FreeBSD ABIs install a dummy gdbarch method that throws an internal_error if it is ever invoked. gdb/ChangeLog: * configure.ac: Check for support for system call LWP fields on FreeBSD. * config.in, configure: Rebuild. * data-directory/Makefile.in (SYSCALLS_FILES): Add freebsd.xml. * fbsd-nat.c (fbsd_wait) [HAVE_STRUCT_PTRACE_LWPINFO_PL_SYSCALL_CODE]: Report system call events.

2016-06-24Add a new gdbarch method to print a single AUXV entry.John Baldwin6-87/+178
Different platforms have different meanings for auxiliary vector entries. The 'print_auxv_entry' gdbarch method allows an architecture to output a suitable description for platform-specific entries. A fprint_auxv_entry function is split out of fprint_target_auxv. This function outputs the description of a single auxiliary vector entry to the specified file using caller-supplied formatting and strings to describe the vector type. The existing switch on auxiliary vector types is moved out of fprint_target_auxv into a new default_print_auxv_entry function. default_print_auxv_entry chooses an appropriate format and description and calls fprint_single_auxv to describe a single vector entry. This function is used as the default 'print_auxv_entry' gdbarch method. fprint_target_auxv now invokes the gdbarch 'print_auxv_entry' method on each vector entry. gdb/ChangeLog: * auxv.c (fprint_auxv_entry): New function.

2016-06-24Fetch the ELF auxiliary vector from live processes on FreeBSD.John Baldwin2-0/+83
Use the kern.proc.auxv.<pid> sysctl to fetch the ELF auxiliary vector for a live process. gdb/ChangeLog: * fbsd-nat.c [KERN_PROC_AUXV] New variable super_xfer_partial. (fbsd_xfer_partial): New function. (fbsd_nat_add_target) [KERN_PROC_AUXV] Set "to_xfer_partial" to "fbsd_xfer_partial".
2016-06-24Add elfcore_grok_freebsd_note to parse FreeBSD ELF core notes.John Baldwin2-9/+139
Move parsing of FreeBSD-specific ELF core notes out of elfcore_grok_note into a new elfcore_grok_freebsd_note function. Add core note grok routines for FreeBSD's psinfo and prstatus notes while here rather than depending on the native handling in elfcore_grok_note. bfd/ChangeLog: * elf.c (elfcore_grok_note): Remove handling of NT_X86_XSTATE for FreeBSD. Remove case for NT_FREEBSD_THRMISC. (elfcore_grok_freebsd_psinfo): New function. (elfcore_grok_freebsd_prstatus): New function. (elfcore_grok_freebsd_note): New function. (elf_parse_notes): Use "elfcore_grok_freebsd_note" for "FreeBSD" notes.
2016-06-24Add constants for FreeBSD-specific auxiliary vector entry types.John Baldwin2-0/+17
include/ChangeLog: * elf/common.h (AT_FREEBSD_EXECPATH, AT_FREEBSD_CANARY) (AT_FREEBSD_CANARYLEN, AT_FREEBSD_OSRELDATE, AT_FREEBSD_NCPUS) (AT_FREEBSD_PAGESIZES, AT_FREEBSD_PAGESIZESLEN) (AT_FREEBSD_TIMEKEEP, AT_FREEBSD_STACKPROT): Define.
2016-06-24Add missing ChangeLog entry for "fix undefined reference [...]" commit.Joel Brobecker1-0/+5
2016-06-24fix undefined reference to bfd_link_plugin_object_p during linkJoel Brobecker1-2/+2
When configured with the default options, GDB currently fails to link, due to an undefined reference to bfd_link_plugin_object_p, coming from elflink.c: #ifdef BFD_SUPPORTS_PLUGINS || (abfd->plugin_format == bfd_plugin_unknown && bfd_link_plugin_object_p (abfd)) #endif This is because BFD_SUPPORTS_PLUGINS is always defined. It is its value that determines whether plugin support is enabled or not. bfd/ChangeLog: * elflink.c: Check the value of BFD_SUPPORTS_PLUGINS rather than its existance.
2016-06-24MIPS objcopy --rename-section fixAlan Modra8-44/+81
Some MIPS targets use a named section symbol rather than a symbol with no name as is used with most ELF targets. When renaming sections, the named section symbol needs to be renamed too. Rather than fix this bug, I'd originally intended to just correct the xfail added recently for update-1.o vs update4.o in update-section.exp, using the same set of targets for the localize-hidden-1 mips xfail. I'd extracted that target test into a new function, is_bad_symtab. It turns out to be useful in readelf.exp too. bfd/ * config.bfd: Delete mips vxworks patterns matched earlier. Combine mips*-*-none with mips*-*-elf*. binutils/ * objcopy.c (find_section_rename): Forward declare. Remove ibfd and sec_ptr param. Add old_name param. Allow for NULL returned_flags. Move read of section name and flags to.. (setup_section): ..here. Update find_section_rename call. (filter_symbols): Rename section symbols for renamed sections. (copy_object): Call filter_symbols when renamed sections. * testsuite/lib/binutils-common.exp (is_bad_symtab): New. * testsuite/binutils-all/update-section.exp: Revert 96037eb0 mips xfail. * testsuite/binutils-all/objcopy.exp (copy_executable): Use is_bad_symtab. (localize-hidden-1): xfail if is_bad_symtab. * testsuite/binutils-all/readelf.exp: Use is_bad_symtab to select between mips/tmips.
2016-06-24aarch64 ld testsuiteAlan Modra2-10/+13
Fixes failure on aarch64-rtems. * testsuite/ld-aarch64/aarch64-elf.exp (aarch64_choose_ilp32_emul): Don't error out, always return an emulation.
2016-06-24alpha-openbsd build failureAlan Modra2-2/+5
This target doesn't build, due to a missing gas/config/te-obsd.h file. It's been that way since the commit switching to elf, in 2002. https://lists.gnu.org/archive/html/bug-gnu-utils/2002-07/msg00128.html * configure.tgt (alpha-*-openbsd*): Use em=nbsd.
2016-06-24Limit objdump -S context linesAlan Modra2-2/+17
Showing context lines is confusing in many cases, an obvious example being loops. * objdump.c (struct print_file_list): Add "max_printed". (try_print_file_open): Init new field. (show_line): Don't show 5 context lines when redisplaying source.
2016-06-24Check DEFAULT_LD_Z_RELRO for -z relro help messageH.J. Lu2-1/+14
* lexsup.c (elf_shlib_list_options): Check DEFAULT_LD_Z_RELRO for -z relro help message.
2016-06-23Move logic out of symbol_find_demangled_nameTom Tromey18-97/+223
This patch moves most of the demangling logic out of symbol_find_demangled_name into the various language_defn objects. The simplest way to do this seemed to be to add a new method to language_defn. This is shame given the existing la_demangle, but given Ada's unusual needs, and the differing demangling options between languages, la_demangle didn't seem to fit. In order to make this work, I made enum language order-sensitive. This helps preserve the current ordering of demangling operations. 2016-06-23 Tom Tromey <tom@tromey.com> * symtab.c (symbol_find_demangled_name): Loop over languages and use language_sniff_from_mangled_name. * rust-lang.c (rust_sniff_from_mangled_name): New function. (rust_language_defn): Update. * p-lang.c (pascal_language_defn): Update. * opencl-lang.c (opencl_language_defn): Update. * objc-lang.c (objc_sniff_from_mangled_name): New function.

2016-06-23Move filename extensions into language_defnTom Tromey16-55/+132
This moves filename extensions from a function in symfile.c out to each language_defn. I think this is an improvement because it means less digging around when writing a new language port. 2016-06-23 Tom Tromey <tom@tromey.com> * ada-lang.c (ada_extensions): New array. (ada_language_defn): Use it. * c-lang.c (c_extensions): New array. (c_language_defn): Use it. (cplus_extensions): New array. (cplus_language_defn): Use it. (asm_extensions): New array.

(_initialize_symfile): Update. * symfile.h (add_filename_language): Declare.
2016-06-23Use VEC for filename_language_tableTom Tromey2-33/+46
This patch changes filename_language_table to be a VEC. This seemed like a reasonable cleanup over the old code. 2016-06-23 Tom Tromey <tom@tromey.com> * symfile.c (filename_language_table): Now a VEC. (fl_table_size, fl_table_next): Remove. (add_filename_language): Use VEC_safe_push. (set_ext_lang_command, info_ext_lang_command) (deduce_language_from_filename): Use VEC_iterate. (init_filename_language_table): Use VEC_empty.
2016-06-23Make gdbpy_parameter staticTom Tromey3-2/+6
While working on the next patch in this series, I noticed that gdbpy_parameter did not need to be exported. This makes it "static". 2016-06-23 Tom Tromey <tom@tromey.com> * python/python.c (gdbpy_parameter): Now static. * python/python-internal.h (gdbpy_parameter): Don't declare.

2016-06-23Fix bug with grouping sections.Cary Coutant6-6/+23
The fix for PR 15370 did not correctly check all patterns in a group, but instead threw all unassigned sections into the group.
