This patch avoids CALL instructions to be optimized into branches if
the symbols referred to in the CALL instruction are not fully resolved
at the time the assembler writes its output.
Tested in sparc64-linux-gnu and sparc-sun-sunos4.1.3 targets.
No regressions.

This patch fixes two problems in the SPARC assembler:
- The diagnostic message
Error: Illegal operands: Immediate value in cbcond is out of range.
is incorrectly issued for non-CBCOND instructions that feature a
simm5 immediate field, such as MPMUL, MONTMUL, etc.
- When an invalid immediate operand is used in a CBCOND
instruction, two redundant error messages are issued to the
user, the second due to a stale fixup (this happens since
commit 85024cd8bcb93f4112470ecdbd6c10fc2aea724f).
Some diagnostic tests for the CBCOND instructions are also
included in the patch.
Tested in both sparc64-linux-gnu and sparcv9-linux-gnu targets.

When the assembler finds an instruction which is part of a higher
opcode architecture it bumps the current opcode architecture. For
example:
$ echo "mwait" | as -bump
{standard input}: Assembler messages:
{standard input}:1: Warning: architecture bumped from "v6" to "v9m" on "mwait"
However, when two instructions pertaining to the same opcode
architecture but associated to different SPARC hardware capabilities
are found in the input stream, and no GAS architecture is specified in
the command line, the assembler bangs:
$ echo "mwait; wr %g0,%g1,%mcdper" | as -bump
{standard input}: Assembler messages:
{standard input}:1: Warning: architecture bumped from "v6" to "v9m" on "mwait"
{standard input}:1: Error: Hardware capability "sparc5" not enabled for "wr".
... and it should'nt, as WRMCDPER pertains to the same architecture
level than MWAIT.
This patch fixes this by extending the definition of sparc opcode
architectures to contain a set of hardware capabilities and making the
assembler to take these capabilities into account when updating the
set of allowed hwcaps when an architecture bump is triggered by some
instruction.
This way, hwcaps associated to architecture levels are maintained in
opcodes, while the assembler keeps the flexibiity of defining GAS
architectures including additional hwcaps (like -Asparcfmaf or the
v8plus* variants).
A test covering this failure case is included.

Merely dumping the mnemonic name in "architecture mismatch" errors may
not provide enough information to determine what went wrong, as the same
mnemonic can be used for different variants of an instruction pertaining

Before SPARC V9 the effect of having a delayed branch instruction in the
delay slot of a conditional delayed branch was undefined.
In SPARC V9 DCTI couples are well defined.
However, starting with the UltraSPARC Architecture 2005, DCTI
couples (of all kind) are deprecated and should not be used, as they may
be slow or behave differently to what the programmer expects.
This patch adds a new command line option --dcti-couples-detect to `as',
disabled by default, that makes the assembler to warn the user if an
unpredictable DCTI couple is found. Tests and documentation are
included.

This patch marks the SPARC instructions in the opcodes table with their
proper opcode architectures, and makes the assembler aware of them.
This allows the assembler to properly realize when a new instruction
needs a higher architecture (after v9b) and to react accordingly
emitting an error message or bumping the architecture.
It also expands architecture mismatch tests to cover architectures
higher than v9b, and fixes a couple of minor bugs in the GAS testsuite.

The current sparc assembler breaks when the name of an ancillary-state
register, privileged register or hyperprivileged register has a
%-pseudo-operation name as a prefix. For example, %hmcdper and %hm(),
or %hintp and %hi().
This patch fixes it by introducing a new table `perc_table' (for
%-table) that contains an entry for every %name supported by the
assembler, other than the general registers. This table is used to
detect name collisions when the assembler tries to detect a %-pseudo-op.
This patch also fixes a related bug, making sure that v9a_asr_table and
hpriv_reg_table are sorted in reverse lexicographic order, as otherwise
the search code may fail.

get_symbol_name () returns a char * in a out arg, which means we need to cast
to assign a literal to the variable passed to get_symbol_name (). It seems
like better APIs than get_symbol_name () could be provided, but that seems like
a fair amount of work so just casting seems to be the betterthing to do for
now.

This is mostly just adding const in many places, however there are a couple
interesting things. We need to add casts in tc-s390.c and tc-cris.c because
they have functions that assign to input_line_pointer an argument that
sometimes comes from md_parse_option. Presumably this is safe because those
targets never pass literals to md_parse_option (), but this code should
probably be improved in the future. Also xtensa passes the argument to strtoll
which is a rather odd function, it takes a const char * as argument and returns
a pointer into that string as a char * through an out argument, but we can work
around that by adding more variables.

In the SPARC V9 (and later) versions of the SPARC specification, the
section C.1.1 "Register Names" specifies that:
"asr_reg. An asr_reg is an Ancillary State Register name. It may have
one of the following values:
%asr16-%asr31"
The rationale of having this restriction was that the registers from 16
to 31 are reserved to implementations, and are therefore "non-V9". It
also assumes that the existing ASR registers in the range 0..31 will
have their own names such as %y, that can be used to access such
registers.
However, this is problematic. When a new ASR register is introduced,
such as %mcdper a.k.a. %asr14, it is useful to be able to use %asr14 in
order to not depend on the latest version of the assembler.
The Solaris assembler is lax and allows to assembly instructions
referring to %asr0 to %asr31. This patch makes the GNU assembler to
mimic that behavior.

* config/tc-sparc.c (sparc_ip): Remove the V9 restriction on ASR

The SPARC Refence Manual documents the %dN and %qN syntax to
refer to double and quad-precision floating-point registers,
respectively. See OSA2015 Appendix C, Assembly Language Syntax,
C1.1 Register Names.
This patch adds support for these names to GAS. This eases the
porting of software from Solaris to GNU/Linux, as these register
names have been supported by the Solaris linker for a long time
and many assembler require that support.

This patch fixes two related problems:
- By default gas is supposed to bump the current architecture
(starting with v6) as it finds "higher" instructions as the
assembling progresses. There are four possible cases depending on
the usage of the -A and -bump options:
(a) No -A and -bump are specified. In this case max_architecture
must be the highest architecture not conflicting with the
default architecture. The default opcode architecture is
indirectly set in configure.tgt and is "v9" in sparc64 systems
(from "v9-64"). Thus the maximum architecture in sparc64
systems must be "v9b". No warnings are echoed when the assembly
of an instruction bumps the current architecture.
(b) Only -bump is specified. This is like (a) but warnings are
always issued when the assembly of an instruction bumps the
current architecture.
(c) Only -A is specified. In this case bumping to a new
architecture is an error.
(d) Both -A and -bump are specified. In this case max_architecture
must be the highest architecture not conflicting with the
default architecture, but warnings are only to be issued when
bumping to an architecture higher than the architecture selected
in the -A option.
`max_architecture' is a global variable defined in tc-sparc.c which
is initialized to the opcode architecture corresponding to the
default architecture ("sparclite" for sparc-* targets and "v9" for
sparc64-* targets). Then in `md_begin' it is set to the highest
non-conflicting architecture, but only when both -A and -bump are
specified.
Thus (a) does not work:
$ echo "fzero %f0" | as
{standard input}: Assembler messages:
{standard input}:1: Error: Architecture mismatch on "fzero".
{standard input}:1: (Requires v9a|v9b; requested architecture is v9.)
Neither (b):
$ echo "fzero %f0" | as -bump
{standard input}: Assembler messages:
{standard input}:1: Error: Architecture mismatch on "fzero".
{standard input}:1: (Requires v9a|v9b; requested architecture is v9.)
Only (d) does:
$ echo "fzero %f0" | as -Av9 -bump
{standard input}: Assembler messages:
{standard input}:1: Warning: architecture bumped from "v6" to "v9a" on "fzero"
This patch fixes that function to "upgrade" `max_architecture' also
in the (a) and (b) cases.
Note that this problem becomes apparent only in sparc64-* targets
because in sparc-* targets the default architecture is the "higher"
among the 32bit architectures ("sparclite").
- Gas maintains a set of hardware capabilities associated with each
gas architecture, in `sparc_arch_table'. On the other hand
libopcodes maintains a set of hardware capabilities needed by each
individual sparc instruction.
When an instruction is assembled in `sparc_ip' gas checks for the
presence of the hardware capabilities required by the instruction,
emitting an error if some capability is missing.
However, this mechanism does not work properly if the current
architecture is bumped due to an instruction requiring new hw
capabilities not present on either the default architecture or an
architecture specified with -A:
$ echo "fzero %f0" | as -bump
{standard input}: Assembler messages:
{standard input}:1: Warning: architecture bumped from "v6" to "v9a" on "fzero"
{standard input}:1: Error: Hardware capability "vis" not enabled for "fzero".
This patch fixes this by adding the set of required hw caps of an
instruction if it triggers an architecture bump.
The patch has been tested in sparc64-unknown-linux-gnu.

A number of targets pass extra information from TC_PARSE_CONS_EXPRESSION
to TC_CONS_FIX_NEW via static variables. That's OK, but not best
practice. tc-ppc.c goes further in implementing its own replacement
for cons(), because the generic one doesn't allow relocation modifiers
on constants. This patch fixes both of these warts.
