When we match against an address type operand within an instruction it
is important that we match exactly the right address type operand early
on, during the opcode selection phase. If we wait until the operand
insertion phase to check that we have the correct address operand, then
it is too late to select an alternative opcode. This becomes important
only when we have multiple opcodes with the same mnemonic, and operand
lists that differ only in the type of the address operands.
This commit fixes this issue, and adds some example instructions that
require this issue to be fixed (the instructions are identical except
for the address type operand).

The current handling for arc instructions longer than 32-bits is all
handled as a special case in both the assembler and disassembler.
The problem with this approach is that it leads to code duplication,
selecting a long instruction is exactly the same process as selecting a
short instruction, except over more bits, in both cases we select based
on bit comparison, and initial operand insertion and extraction.
This commit unifies both the long and short instruction worlds,
converting the core opcodes library from being largely 32-bit focused,
to being largely 64-bit focused.
The changes are, on the whole, not too much. There's obviously a lot of
type changes but otherwise the bulk of the code just works. Most of the
actual functional changes are to code that previously handled the longer
48 or 64 bit instructions. The insert/extract handlers for these have
now been brought into line with the short instruction insert/extract
handlers.
All of the special case handling code that was previously added has now
been removed again. Overall, this commit reduces the amount of code in
the arc assembler and disassembler.

In preparation for moving to a world where arc instructions can be 2, 4,
6, or 8 bytes in length, replace the ARC_SHORT macro (which is either
true of false) with an arc_opcode_len function that returns a length in
bytes.
There should be no functional change after this commit.

The code supporting -mspfp, -mdpfp, and -mfpuda options are in
sections of code that are commented as being for backward
compatibility only, and having no effect. However, they do have an
effect, enabling the SPX, DPX, and DPA instruction subclasses
respectively. This commit moves the code supporting these options
away from the comments indicating that they are dummy options, and
also fixes a small issue where -mnps400 had the additional effect
of enabling SPX instructions.
A couple of other minor edits (that make no functional change) are
also included.
gas/ChangeLog:
* config/tc-arc.c (options, md_longopts, md_parse_option):
Move -mspfp, -mdpfp and -mfpuda out of the sections for
dummy options. Correct erroneous enabling of SPFP
instructions when using -mnps400.

features.

This commit adds the ldbit instruction for the NPS-400. The ldbit
instruction uses the same encoding as the ld instruction, but sets
the ZZ field to 11 (which is a reserved setting), and sets the AA
field to 1 or 2 for the x2 and x4 flags respectively.
|
|
With the exception of ldbit, this commit adds implementations of
all DPI instructions for the NPS-400. These instructions are:
- hash / hash.p[0-3]
- tr
- utf8
- e4by
- addf

This commit completes the implementation of arithmetic and logic
instructions for the NPS-400. These instructions are:
- calcbsd / calcbxd
- calckey / calcxkey
- mxb / imxb
- addl, subl, orl, andl, xorl
- andab / orab
- lbdsize
- bdlen
- csms, csma, cbba

This commit completes support for having multiple instructions with the
same mnemonic in non-contiguous blocks within the arc_opcodes table.
The commit adds an iterator mechanism for the arc_opcode_hash_entry
structure, which is then used in find_opcode_match to consider all
arc_opcode entries with the same mnemonic, even when these instructions
are stored in non-contiguous blocks.
I extend the comment on the arc_opcodes table to discuss how entries
within the table are organised, and to mention how instructions can be
split into multiple groups if needed, but that the table is still
searched in table order.
There should be no user visible changes after this commit.

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.

This commit restructures the selection of the default cpu/mach so that
the choice is made from md_begin (if the user has not provided a command
line choice). This will reduce the amount of change needed in a later
patch.
At the request of Synopsys, the default architecture changes to ARC700
from this commit, previously the default was a non-existent
super-architecture that contained all instructions from all arc
variants. There's some clean up associated with removing the default
merged architecture, and a small test fix now that the default is
ARC700.

* testsuite/binutils-all/objdump.exp (cpus_expected): Add ARC700
to the architecture list.
