7f20e1614f Fix parsing of 'vmov Q<n>.F32,Q<n>.F32' instruction.
parse_qfloat_immediate() accidentaly parses register with size
qualifier as immediate constant (It takes '<n>.' substring as
valid floating point constant).

Due to this, slightly reorder cases in parse_neon_mov() and move parsing of
vmov with immediate constant to last place.

5be48d84be add octeon+ as an alias for octeon in GCC & binutils
In r208737 jmallett@ added support for the "mips64r2" architecture
and "octeon" CPU, and the saa/saad instructions.

Upstream binutils also added the "octeon+" CPU, and the saa/saad
instructions are only available in octeon+, not octeon.  Since our
base system tool chain already accepts saa/saad with -march=octeon,
just allow octeon+ as an alias.

This allows the use of octeon+ in kernel config files, for use with both
external tool chain and in-tree GCC/binutils.

66c8095956 Rename elf*-powerpc into elf*-powerpc-freebsd in binutils
The powerpc support was the only supported architecture not prepending the elf format name
with "-freebsd" in base this change makes it consistent with other architectures.
On newer version of binutils the powerpc format is also prepended with "-freebsd".

Also modify the kernel ldscripts in that regards.

As a result it is now possible cross build the kernel on powerpc using newer binutils

0162755064 Allow vld and vst instructions to use the canonical form from ARM ARM when
including an alignment. Previously binutils would only allow instructions
in the form "vld1.64 {d0, d1}, [r0, :128]" where the final comma should
not be there, instead the above instruction should be
"vld1.64 {d0, d1}, [r0:128]".

This change duplicates the alignment code from within the function to
handle this case.

2d0ef32f84 Teach as(1) to handle the arm .arch_extension pseudo-op, which accepts
the same values as the -march= command line option.  Add support for the
"sec" extension (security extensions).

We've been getting away without support for the sec extension because
it's bogusly enabled even on arches where its presence is optional.  This
support for .arch_extension is being added mainly so that we can use the
right directives in our source code, and that helps folks using external
toolchains (and will help us when we finally update our toolchain).

90ab443e31 Some ARM vmov similar to 'vmov.f32 s1, s2' will incorrectly have the second
register added to the symbol table by the assembler. On further
investigation it was found the problem was with the my_get_expression
function. This is called by parse_big_immediate.

Fix this by moving the call to parse_big_immediate to the end of the if,
else if, ..., else block.

4da573d910 Merging of projects/armv6, part 3
r238211:
Support TARGET_ARCH=armv6 and TARGET_ARCH=armv6eb

This adds a new TARGET_ARCH for building on ARM
processors that support the ARMv6K multiprocessor
extensions.  In particular, these processors have
better support for TLS and mutex operations.

This mostly touches a lot of Makefiles to extend
existing patterns for inferring CPUARCH from ARCH.
It also configures:
 * GCC to default to arm1176jz-s
 * GCC to predefine __FreeBSD_ARCH_armv6__
 * gas to default to ARM_ARCH_V6K
 * uname -p to return 'armv6'
 * make so that MACHINE_ARCH defaults to 'armv6'
It also changes a number of headers to use
the compiler __ARM_ARCH_XXX__ macros to configure
processor-specific support routines.
