This is a version of the patch posted by Trevor Saunders on 2017-07-31,
for which he wrote:
> For most of the history of this see
>   https://sourceware.org/ml/gdb-patches/2016-10/msg00223.html
> The changes are mostly s/gdb/gtl/g

This version was updated by me (dmalcolm) adding these changes:
- renaming of "gtl" to "gnu" (3 letters, and one of the ones Richi
  proposed, and not a match for "*tl")
- renaming of DEFINE_GDB_UNIQUE_PTR to DEFINE_GNU_UNIQUE_PTR
- renaming of xfree_deleter to xmalloc_deleter, and making it
  use "free" rather than "xfree" (which doesn't exist)
- added a gcc/unique-ptr-tests.cc
- implement unique_xmalloc_ptr<T[]> (taken from gdb, but changing
  "xfree" to "free", and adding support for pre-C++-11)

gcc/ChangeLog:

	David Malcolm <dmalcolm@redhat.com>

	* Makefile.in (OBJS): Add unique-ptr-tests.o.
	* selftest-run-tests.c (selftest::run_tests): Call

DSP instructions are optional for Arm Cortex-M33, yet its -mcpu option
does not allow +nodsp. Users are thus left with using
-march=armv8-m.main -mtune=cortex-m33. This patch allows +nodsp to
-mcpu=cortex-m33.

Fix PR82442

Recently the gcc.dg/vect/pr31699.c was modified to check for
vect_float effective target instead for vect_double.  As a

Tested on armhf, aarch64 and x64.
