      Fix test for availability of emplace_back. · 21555352
      Cary Coutant authored
      Testing for the GCC version 5 or later isn't right, since C++ 11 support
      wasn't enabled by default until later.  This patch tests the C++ standard
      support directly instead of inferring it from the GCC version.

      GNU attribute output on errors · bdb5f07b
      Alan Modra authored
      .gnu.attributes entries from linker input files are merged to the
      output file, the output having the union of compatible input
      attributes.  Incompatible attributes generally cause a linker error
      and no output.  However in some cases only a warning is emitted, and
      one of the incompatible input attributes is passed on to the output.
      PowerPC tends to emit warnings rather than errors, and the output
      takes the first input attribute.  For example, if we have two input
      files with Tag_GNU_Power_ABI_FP, the first with a value signifying
      "double-precision hard float, IBM long double", the second with a
      value signifying "double-precision hard float, IEEE long double",
      we'll get a warning about incompatible long double types and the
      output will say "double-precision hard float, IBM long double".
      The output attribute of course isn't correct.  It would be correct to
      specify "IBM and IEEE long double", but we don't have a way to
      represent that currently.  While it would be possible to extend the
      encoding, there isn't much gain in doing so.  A shared library
      providing support for both long double types should link against
      objects using either long double type without warning or error.  That
      is what you'd get if such a shared library had no Tag_GNU_Power_ABI_FP
      So this patch provides a way for the backend to omit .gnu.attributes
      tags from the output.

      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.
