      MIPS16/GAS: Restore unsupported relocation diagnostics · 88a7ef16
      Maciej W. Rozycki authored
      Correct a MIPS16 relocation handling regression in GAS introduced with:
      
      commit 177b4a6a
      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.

      Add support for catching system calls to native FreeBSD targets. · e6cdd38e
      John Baldwin authored
      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-tdep.c: Include xml-syscall.h
      	(fbsd_get_syscall_number): New function.
      	(fbsd_init_abi): Set XML system call file name.

      Add a new gdbarch method to print a single AUXV entry. · 2faa3447
      John Baldwin authored
      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.

      fix undefined reference to bfd_link_plugin_object_p during link · 08ce1d72
      Joel Brobecker authored
      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

      MIPS objcopy --rename-section fix · 9cc0123f
      Alan Modra authored
      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.

      Move logic out of symbol_find_demangled_name · 8b302db8
      Tom Tromey authored
      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.

      PR gdb/16483 - simplify "info frame-filters" output · 17621150
      Tom Tromey authored
      PR gdb/16483 notes that the output of "info frame-filters" is quite
      voluminous.  In particular it prints an entry for each objfile, even if
      only to say that the objfile does not have any associated frame filters.
      
      I think it's better to only print output when there is a frame filter.
      There's nothing worth doing with the no-frame-filter information, and
      limiting the output makes it much more readable.

      [ARC] Misc minor edits/fixes · ce440d63
      Graham Markall authored
      The code supporting -mspfp, -mdpfp, and -mfpuda options are in
      sections of code that are commented as being for backward
      compatibility only, and having no effect. However, they do have an
      effect, enabling the SPX, DPX, and DPA instruction subclasses
      respectively. This commit moves the code supporting these options
      away from the comments indicating that they are dummy options, and
      also fixes a small issue where -mnps400 had the additional effect
      of enabling SPX instructions.
      
      A couple of other minor edits (that make no functional change) are
      also included.
      
      gas/ChangeLog:
      
              * config/tc-arc.c (options, md_longopts, md_parse_option):
              Move -mspfp, -mdpfp and -mfpuda out of the sections for
              dummy options. Correct erroneous enabling of SPFP
              instructions when using -mnps400.
