    • [arm] Fix various tests · e3e266bf 
      The neon-thumb2-move.c test was overriding the options that had been
detected as being necessary to enable Neon.  The result was that the
combination of the test's options and those auto-detected were not
compatible with neon leading to a test failure.  The correct fix here
is to stick with the options that dg-add-options arm_neon has worked
out.

The thumb2-slow-flash-data tests were relying (incorrectly) on a
particular FPU being enabled by default.  These tests are fixed by
adding +fp to the architecture selected.

    • [arm] Mark -marm and -mthumb as being inverse options · 718a3eab 
      -marm and -mthumb are opposites: one cancels out the other.  This patch
marks them as such so that the driver will eliminate all but the last
option on the command line.  This aids multilib selection which otherwise
can get confused if both are present.

    • [arm][doc] Document changes to -mcpu, -mtune and -mfpu. · f54133ea 
      This patch adds the remainder of the main documentation changes.  It
adds the changes for -mcpu, -mtune and -mfpu.  I've chosen to document
the extension options under -mcpu rather than under -mtune because,
while they are permitted with -mtune, they do not affect the behaviour
of the tuning done by the compiler.

I've also inverted the sense of the table (making the primary index
the extension name and then listing the CPU names to which it applies.
This is because the extensions are much more orthoganal in meaning
here and having a primary entry via the CPU name would lead to
enormous duplication.

Finally, it adds the relevant changes to -mfpu.  I haven't stated yet
that any setting of -mfpu other than 'auto' is deprecated, but that is
certainly the long-term goal of this patch series.

	* doc/invoke.texi (ARM Options, -mcpu): Document supported
	extension options.
	(ARM Options, -mtune): Document that this accepts the same
	extension options as -mcpu.
	(ARM Options, -mfpu): Document addition of -mfpu=auto.

    • [arm] Rework multilib support · be5c4e06 
      It looks like the fuchsia port relied on inheriting the multilib rules from
the bare-metal port (the t-arm-elf makefile fragment), but that has now been
rewritten on the assuption that the base architecture is ARMv4t; fuchsia
has a base architecture of ARMv7-a.

To account for this, I've cloned the original t-arm-elf rules into a
new makefile fragment t-fuchsia and arranged for that to be used when
targetting this system.

	* config/arm/t-fuchsia: New file.
	* config.gcc (arm*-*-fuchsia*): Use it.

    • [arm] Rework multlib builds for symbianelf · e61a3cdd 
      Symbianelf used to build multilib for armv5t with softfp, but that
architecture doesn't really support floating point instructions.  This
patch reworks the multilib configuration to use armv5te as the base
when building for floating point.

I'm not sure just how useful the symbian port is these days, so this
has only been very lightly tested (checks that libgcc builds for all
multilib variants).  Perhaps we should consider deprecating this
config?

	* config/arm/t-symbian: Rewrite for new option infrastructure.

    • [arm] reset all multilib variables · 99d6bcf7 
      NB.  This configuration does not build in GCC-7 and doesn't build now either.

This patch resets a couple of multlib variables which previously were
not cleared.

It almost certainly needs further work to make it use the new option
framework correctly, but since the library configurations are already
clearly wrong, it's not clear what the changes need to be.  In
particular it tries to build a hard-float library for ARM7TDMI in both
ARM and thumb modes, but ARMv4t does not support any floating-point
instructions; furthermore, GCC has never supported a hard-float thumb1
library.

	* config/arm/t-phoenix (MULTILIB_REUSE): Clear variable.

    • [arm] Update t-rtems for new option framework · d59ee314 
      [This patch has only been fairly lightly tested (I've built a compiler
with all the relevant multilibs and smoke-tested a few combinations to
check that the tools still produce a sensible object file).]

This patch updates the RTEMS build to use the new option framework.
It tries as far as possible to keep the existing supported options,
but there are two necessary changes and one cleanup.  I've also
restructed the file slightly to make it slightly easier (IMO) to
understand.

Necessary changes:

1: ARMv4t does not support a hard-float ABI, the earliest supported
architecture with floating-point support is ARMv5te, so I've rebased
the original fpu/hard libraries to that revision of the architecture.

2: Similarly, the earliest version of the -m profile to support
hardware floating-point is armv7e-m (not armv7-m), so the base
architecture for m-profile with FP has been correspondingly updated.

Clean-up:

1: For greater consistency I've changed the
-mcpu=cortex-m7/-mfpu=fpv5-d16/-mhard-float to
-march=armv7e-m+fp.dp/-mhard-float.  The built-in -mcpu rewrite rules
take care of mapping the existing option sets onto the architecture
string to ensure compatibility.

Since the existing rule set does not contain any MULTILIB_REUSE rules,
I have not added any here this time around, but it would be worth the
maintainers of this file considering whether adding some rules would
make their toolchain more friendly to users.

Finally, I've added lines to reset all the multilib variables at the
head of the file.  I found during testing that some definitions from
t-arm-elf were leaking through and causing unexpected behviour.

	* config/arm/t-rtems: Rewrite for new option framework.
