      [Patch AArch64] Warn on unpredictable stlxrb , stlxrh and stlxr cases. · 513e3973
      Ramana Radhakrishnan authored
      A recent case in golang highlighted that gas wasn't warning on these
      unpredictable cases in the architecture. Fixed thusly.
      I need to audit gcc to make sure we have early clobbers on the
      patterns but that's a separate patch.
      Tested aarch64-none-elf and gas
      Ok ?

      Fix AArch64 encodings for by element instructions. · 48d86a7a
      Tamar Christina authored
      Some instructions in Armv8-a place a limitation on FP16 registers that can be
      used as the register from which to select an element from.
      e.g. fmla restricts Rm to 4 bits when using an FP16 register.  This restriction
      does not apply for all instructions, e.g. fcmla does not have this restriction
      as it gets an extra bit from the M field.
      Unfortunately, this restriction to S_H was added for all _Em operands before,
      meaning for a large number of instructions you couldn't use the full register
      This fixes the issue by introducing a new operand _Em16 which applies this
      restriction only when paired with S_H and leaves the _Em and the other
      qualifiers for _Em16 unbounded (i.e. using the full 5 bit range).
      Also the patch updates all instructions that should be affected by this.

      Correct negs aliasing on AArch64. · 514cd3a0
      Tamar Christina authored
      This patch fixes a disassembly issue with the aliases to subs with a shifted
      register.  The subs instruction with the zero register as destination is
      supposed to alias to cmp and when the first input register is the zero register
      the subs is supposed to be aliased to negs.
      This means that a subs with destination and first input registers the zero
      register is supposed to be a cmp.
      This is done by raising the priority of the cmp alias.

      Bump to autoconf 2.69 and automake 1.15.1 · d0ac1c44
      Simon Marchi authored
      When trying to run the update-gnulib.sh script in gdb, I get this:
      Error: Wrong automake version (Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/\${ <-- HERE ([^      =:+{}]+)}/ at /opt/automake/1.11.1/bin/automake line 4113.), we need 1.11.1.
      Apparently, it's an issue with a regex in automake that triggers a
      warning starting with Perl 5.22.  It has been fixed in automake 1.15.1.
      So I think it's a good excuse to bump the versions of autoconf and
      automake used in the gnulib import.  And to avoid requiring multiple
      builds of autoconf/automake, it was suggested that we bump the required
      version of those tools for all binutils-gdb.
      For autoconf, the 2.69 version is universally available, so it's an easy
      choice.  For automake, different distros and distro versions have
      different automake versions.  But 1.15.1 seems to be the most readily
      available as a package.  In any case, it's easy to build it from source.
      I removed the version checks from AUTOMAKE_OPTIONS and AC_PREREQ,
      because I don't think they are useful in our case.  They only specify a
      lower bound for the acceptable version of automake/autoconf.  That's
      useful if you let the user choose the version of the tool they want to
      use, but want to set a minimum version (because you use a feature that
      was introduced in that version).  In our case, we force people to use a
      specific version anyway.  For the autoconf version, we have the check in
      config/override.m4 that enforces the version we want.  It will be one
      less thing to update next time we change autotools version.
      I hit a few categories of problems that required some changes.  They are
      described below along with the chosen solutions.
      Problem 1:
        configure.ac:17: warning: AM_INIT_AUTOMAKE: two- and three-arguments forms are deprecated.  For more info, see:
        configure.ac:17: http://www.gnu.org/software/automake/manual/automake.html#Modernize-AM_005fINIT_005fAUTOMAKE-invocation
      Solution 1:
        Adjust the code based on the example at that URL.
      Problem 2 (in zlib/):
        Makefile.am: error: required file './INSTALL' not found
        Makefile.am:   'automake --add-missing' can install 'INSTALL'
        Makefile.am: error: required file './NEWS' not found
        Makefile.am: error: required file './AUTHORS' not found
        Makefile.am: error: required file './COPYING' not found
        Makefile.am:   'automake --add-missing' can install 'COPYING'
      Solution 2:
        Add the foreign option to AUTOMAKE_OPTIONS.
      Problem 3:
        doc/Makefile.am:20: error: support for Cygnus-style trees has been removed
      Solution 3:
        Remove the cygnus options.
      Problem 4:
        Makefile.am:656: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or '*_CPPFLAGS')
      Solution 4:
        Rename "INCLUDES = " to "AM_CPPFLAGS += " (because AM_CPPFLAGS is
        already defined earlier).
      Problem 5:
        doc/Makefile.am:71: warning: suffix '.texinfo' for Texinfo files is discouraged; use '.texi' instead
        doc/Makefile.am: warning: Oops!
        doc/Makefile.am:     It appears this file (or files included by it) are triggering
        doc/Makefile.am:     an undocumented, soon-to-be-removed automake hack.
        doc/Makefile.am:     Future automake versions will no longer place in the builddir
        doc/Makefile.am:     (rather than in the srcdir) the generated '.info' files that
        doc/Makefile.am:     appear to be cleaned, by e.g. being listed in CLEANFILES or
        doc/Makefile.am:     DISTCLEANFILES.
        doc/Makefile.am:     If you want your '.info' files to be placed in the builddir
        doc/Makefile.am:     rather than in the srcdir, you have to use the shiny new
        doc/Makefile.am:     'info-in-builddir' automake option.
      Solution 5:
        Rename .texinfo files to .texi.
      Problem 6:
        doc/Makefile.am: warning: Oops!
        doc/Makefile.am:     It appears this file (or files included by it) are triggering
        doc/Makefile.am:     an undocumented, soon-to-be-removed automake hack.
        doc/Makefile.am:     Future automake versions will no longer place in the builddir
        doc/Makefile.am:     (rather than in the srcdir) the generated '.info' files that
        doc/Makefile.am:     appear to be cleaned, by e.g. being listed in CLEANFILES or
        doc/Makefile.am:     DISTCLEANFILES.
        doc/Makefile.am:     If you want your '.info' files to be placed in the builddir
        doc/Makefile.am:     rather than in the srcdir, you have to use the shiny new
        doc/Makefile.am:     'info-in-builddir' automake option.
      Solution 6:
        Remove the hack at the bottom of doc/Makefile.am and use
        the info-in-builddir automake option.
      Problem 7:
        doc/Makefile.am:35: error: required file '../texinfo.tex' not found
        doc/Makefile.am:35:   'automake --add-missing' can install 'texinfo.tex'
      Solution 7:
        Use the no-texinfo.tex automake option.  We also have one in
        texinfo/texinfo.tex, not sure if we should point to that, or move it
        (or a newer version of it added with automake --add-missing) to
      Problem 8:
        Makefile.am:131: warning: source file 'config/tc-aarch64.c' is in a subdirectory,
        Makefile.am:131: but option 'subdir-objects' is disabled
        automake: warning: possible forward-incompatibility.
        automake: At least a source file is in a subdirectory, but the 'subdir-objects'
        automake: automake option hasn't been enabled.  For now, the corresponding output
        automake: object file(s) will be placed in the top-level directory.  However,
        automake: this behaviour will change in future Automake versions: they will
        automake: unconditionally cause object files to be placed in the same subdirectory
        automake: of the corresponding sources.
        automake: You are advised to start using 'subdir-objects' option throughout your
        automake: project, to avoid future incompatibilities.
      Solution 8:
        Use subdir-objects, that means adjusting references to some .o that will now
        be in config/.
      Problem 9:
        configure.ac:375: warning: AC_LANG_CONFTEST: no AC_LANG_SOURCE call detected in body
        ../../lib/autoconf/lang.m4:193: AC_LANG_CONFTEST is expanded from...

        configure.ac:375: the top level
      Solution 9:
        Use AC_LANG_SOURCE, or use proper quoting.
      Problem 10 (in intl/):
        configure.ac:7: warning: AC_COMPILE_IFELSE was called before AC_USE_SYSTEM_EXTENSIONS

      x86: relax redundant REX prefix check · 44846f29
      Jan Beulich authored
      All REX bits can be specified via individual prefixes. Redundancy should
      only be reported on a per-bit basis.
      Note that I originally had further checks added to the test case,
      checking the effect also on PDEP. I had to strip those, because my patch
      to correctly handle those
      (https://sourceware.org/ml/binutils/2017-02/msg00280.html) was rejected.
      I continue to think that there should not be any new prefix introduced
      to handle the VEX case - whether the encoding of an insn requires VEX et
      al should not be of immediate interest to the programmer.

      x86: tighten condition for emitting LOCK on control register accesses · e0c7f900

      The control register is never expressed by REX.B; this bit only affects
      the involved GPR. Also only one of the operands can have its "control"
      flag set, so only check the correct operand.

      Implement Read/Write constraints on system registers on AArch64 · f9830ec1
      Tamar Christina authored
      This patch adds constraints for read and write only system registers with the
      msr and mrs instructions.  The code will treat having both flags set and none
      set as the same.  These flags add constraints that must be matched up. e.g. a
      system register with a READ only flag set, can only be used with mrs.  If The
      constraint fails a warning is emitted.
      Examples of the warnings generated:
      test.s: Assembler messages:
      test.s:5: Warning: specified register cannot be written to at operand 1 -- `msr dbgdtrrx_el0,x3'
      test.s:7: Warning: specified register cannot be read from at operand 2 -- `mrs x3,dbgdtrtx_el0'
      test.s:8: Warning: specified register cannot be written to at operand 1 -- `msr midr_el1,x3'
      and disassembly notes:
      0000000000000000 <main>:
         0:	d5130503 	msr	dbgdtrtx_el0, x3

      Note that because dbgdtrrx_el0 and dbgdtrtx_el0 have the same encoding, during
      disassembly the constraints are use to disambiguate between the two.  An exact
      constraint match is always prefered over partial ones if available.
      As always the warnings can be suppressed with -w and also be made errors using
      warnings as errors.

      Allow non-fatal errors to be emitted and for disassembly notes be placed on AArch64 · 7d02540a
      Tamar Christina authored
      This patch adds a new platform option "notes" that can be used to indicate if
      disassembly notes should be placed in the disassembly as comments.
      These notes can contain information about a failing constraint such as reading
      from a write-only register.  The disassembly will not be blocked because of this
      but -M notes will emit a comment saying that the operation is not allowed.
      For assembly this patch adds a new non-fatal status for errors.  This is
      essentially a warning.  The reason for not creating an actual warning type is
      that this causes the interaction between the ordering of warnings and errors to
      be problematic.  Currently the error buffer is almost always filled because of
      the way operands are matched during assembly. An earlier template may have put
      an error there that would only be displayed if no other template matches or
      generates a higher priority error.  But by definition a warning is lower
      priority than a warning, so the error (which is incorrect if another template
      matched) will supersede the warning.  By treating warnings as errors and only
      later relaxing the severity this relationship keeps working and the existing
      reporting infrastructure can be re-used.

      Modify AArch64 Assembly and disassembly functions to be able to fail and report why. · 561a72d4
      Tamar Christina authored
      This patch if the first patch in a series to add the ability to add constraints
      to system registers that an instruction must adhere to in order for the register
      to be usable with that instruction.
      These constraints can also be used to disambiguate between registers with the
      same encoding during disassembly.
      This patch adds a new flags entry in the sysreg structures and ensures it is
      filled in and read out during assembly/disassembly. It also adds the ability for
      the assemble and disassemble functions to be able to gracefully fail and re-use
      the existing error reporting infrastructure.
      The return type of these functions are changed to a boolean to denote success or
      failure and the error structure is passed around to them. This requires
      aarch64-gen changes so a lot of the changes here are just mechanical.
