Correct a regression introduced with commit 919731affb ("Add MIPS
.module directive") causing code like:
.set mips3
dli $2, 0x9000000080000000
to fail assembly with the following error message produced:
Error: number (0x9000000080000000) larger than 32 bits
if built with `mips3' selected as the global ISA (e.g. `-march=mips3').
This is because a `.set' directive doing an ISA override does not lift
the ABI restriction on register sizes if the ISA remains unchanged.
Previously the directive always set register sizes from the ISA chosen,
which is what some code expects. Restore the old semantics then.

The RAS extension was introduced as part of the ARMv8.2 architecture
where it is a required feature. It is also available as an optional
feature for ARMv8 and ARMv8.1. In binutils, the RAS extension is
currently enabled by default for -march=armv8.2-a but is not available
for -march=armv8 or -march=armv8.1-a.
This patch adds the feature extension '+ras' to enable the RAS extension
for ARMv8 and ARMv8.1, it is disabled by default.

Add support for arc/nps400 cmem instructions, these load and store
instructions are hard-wired to access "0x57f00000 + 16-bit-offset".
Supporting this relocation required some additions to the arc relocation
handling in the bfd library, as well as the standard changes required to
add a new relocation type.
There's a test of the new instructions in the assembler, and a test of
the relocation in the linker.

Weak symbols can be preempted at link time so always choose the longer

Where branch relaxation is enabled emit the long sequence for branches
whose distance cannot be determined, i.e. to symbols that are undefined
or in a different segment. These symbols are only resolved at link time
and therefore the longer sequence ensures the branch target is in range,
which cannot be guaranteed with a direct branch.
This is the opposite to the current implementation, originally proposed
here: <https://sourceware.org/ml/binutils/2002-09/msg00218.html>. The
proposal was then extensively discussed before the final version was
posted here: <https://sourceware.org/ml/binutils/2002-10/msg00191.html>
and eventually committed:
commit 4a6a3df43d
Author: Alexandre Oliva <aoliva@redhat.com>
Date: Sat Oct 12 05:23:33 2002 +0000
The case considered here was not commented in the review however and the
original version remains. With branch relaxation enabled it makes more
sense to do it consistently, so that all code impure with respect to
branch distances can be linked. Direct branches are still produced for
the cases concerned where branch relaxation is disabled, which is the
default.

When parsing the operand instruction flags we don't currently detect the
case where multiple flags are provided from the same class set, these
will be accepted and the bit values merged together, resulting in the
wrong instruction being assembled. For example:
adc.n.eq r0,r0,r2
Will assemble without error, yet, upon disassembly, the instruction will
actually be:
adc.c r0,r0,r2
In a later commit the concept of required flags will be introduced.
Required flags are just like normal instruction flags, except that they
must be present for the instruction to match. Adding this will allow
for simpler instructions in the instruction table, and allow for more
sharing of operand extraction and insertion functions.
To solve both of the above issues (multiple flags being invalid, and
required flags), this commit reworks the flag class mechanism.
Currently the flag class is never used. Each instruction can reference
multiple flag classes, each flag class has a class type and a set of
flags. However, at present, the class type is never used. The current
values identify the type of instruction that the flag will be used in,
but this is not required information.
Instead, this commit discards the old flag classes, and introduces 3 new
classes. The first F_CLASS_NONE, is just a NULL marker value, and is
only used in the NULL marker flag class. The other two flag classes are
F_FLAG_OPTIONAL, and F_FLAG_REQUIRED.
The class F_FLAG_OPTIONAL has the property that at most one of the flags
in the flag set for that class must be present in the instruction. The
"at most" one means that no flags being present is fine.
The class F_FLAG_REQUIRED is not currently used, but will be soon. With
this class, exactly one of the flags from this class must be present in
the instruction. If the flag class contains a single flag, then of
course that flag must be present. However, if the flag class contained
two or more, then one, and only one of them must be present.

The inline-data test checks the specific bytes laid down by the
assembler, and so relies on the endianness of the target. I could
change the expected results to be endian agnostic, however, I worried
that a bug in the assembler that gets the endianness wrong would then
slip through. Instead I add a new test for big-endian arc, and restrict
the existing test to little-endian arc.
