Use the module level ISA setting rather than the last ISA selected with
a `.set' directive in the source file in determination as to whether to
keep PC-relative relocations and then with the original symbol referred,
for the purpose of R6 linker relaxation.
This is so that with e.g. code like this:
b foo
.set mips32r2
...
it's the command line options or any `.module' directive that decides
how to encode any relocation for `foo' rather than the presence of `.set
mips32r2'.

This patch fixes and expands the definition of the read/write
instructions for ancillary-state, privileged and hyperprivileged
registers in opcodes.
It also adds support for three new v9m hyperprivileged registers:
%hmcdper, %hmcddfr and %hva_mask_nz.
Finally, the patch expands existing tests (and adds several new ones) in
order to cover all the read/write instructions in all its variants.

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.

VLE is an encoding, not a particular processor architecture, so it
isn't really proper to select insns based on PPC_OPCODE_VLE. For
example
{"evaddw", VX (4, 512), VX_MASK, PPCSPE|PPCVLE, PPCNONE, {RS, RA, RB}},
{"vaddubs", VX (4, 512), VX_MASK, PPCVEC|PPCVLE, PPCNONE, {VD, VA, VB}},
shows two insns that have the same encoding, both available with VLE.
Enabling both with VLE means we can't disassemble the second variant
even if -Maltivec is given rather than -Mspe. Also, we don't check
user assembly against the processor type as well as we could.
Another problem is that when using the VLE encoding, insns from the
main ppc opcode table are not available, except those using opcode 4
and 31. Correcting this revealed two errors in the ld testsuite,
use of "nop" and "rfmci" when -mvle.
This patch fixes those problems in the opcode table, and removes
PPCNONE. I find a plain 0 distracts less from other values.
In addition, I've implemented code to recognize some machine values
from the apuinfo note present in ppc32 objects. It's not a complete
disambiguation since we're lacking info to detect newer chips, but
what we have should help with disassembly.

With code refactoring made in commit b886a2ab0d and the addition of
`calculate_reloc' and a separate test for TLS relocs against constants
made there the preexisting fall-through from the TLS reloc switch case
has effectively become a dead execution path. This is because the call
to `calculate_reloc' present there is only made if `fixP->fx_done' is
true, which can only be the case if `fixP->fx_addsy' is NULL, which in
turn has already triggered the TLS reloc test and made execution break
out of the switch statement.
Remove the fall-through then and reshape code accordingly.

The microMIPS JALX instruction shares the R_MICROMIPS_26_S1 relocation
with microMIPS J/JAL/JALS instructions, however unlike the latters its
encoded immediate argument is unusually shifted left by 2 rather than 1
in calculating the value used for the operation requested.
We already handle this exception in `mips_elf_calculate_relocation' in
LD, in a scenario where JALX is produced as a result of relaxing JAL for
the purpose of making a cross-mode jump. We also get it right in the
disassembler in `decode_micromips_operand'.
What we don't correctly do however is processing microMIPS JALX produced
by GAS from an assembly source, where a non-zero constant argument or a
symbol reference with a non-zero in-place addend has been used. In this
case the same calculation is made as for microMIPS J/JAL/JALS, causing
the wrong encoding to be produced by GAS on making an object file, and
then again by LD in the final link. The latter in particular causes the
calculation, where the addend fits in the relocatable field, to produce
different final addresses for the same source code depending on whether
REL or RELA relocations are used.
Correct these issues by special-casing microMIPS JALX in the places that
have been previously missed.

The opcode array iterator mechanism can, in some situations, result in
reading memory outside of the opcode array. When using the
iterator-next mechanism to find the next possible arc_opcode, if we find
an opcode where the name field is NULL, or the name does not match, then
the cached opcode pointer is not set to NULL. The result is that
another call to iterator-next will again increment the opcode
pointer (which might now point outside the opcode array) and attempt to
access the name field of this undefined opcode.
Fixed in this commit by clearing the cached opcode pointer.

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.

Presumably this was supposed to be regname[sizeof (regname) - 1] but was typoed
to regname[sizeof (rename) - 1]. However that should be unnecessary because
sprintf should null terminate. As is this assignment is invalid ISO C because
rename refers to the function rename (), and sizeof on functions is undefined.
In GNU C C the size of functions is 1 so the expression is the same as
regname[0]. The following call to sprintf () clearly will over right that, so
the statement either has no effect or is invalid. Given that it seems safe to
just remove it. While we are there correct the size of regname, and switch
from snprintf to sprintf since we know the exact length of the result.

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.

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.

Building on earlier commits, this commit moves along support for having
multiple arc_opcode entries in the arc_opcodes table that have the same
mnemonic (name) field, but are not stored in a contiguous block in the
table.
In this commit we support looking up the arc_opcode_hash_entry from the
hash table, and passing this along to the find_opcode_match function,
which then finds the specific arc_opcode that we're assembling. We
still don't actually support the multiple chains of arc_opcode entries
in this commit, but the limitation is now isolated to the
find_opcode_match function.
There is no user visible change after this commit.
gas/ChangeLog:

arc_opcode_hash_entry pointer.

(assemble_tokens): Lookup arc_opcode_hash_entry based on

The arc assembler builds a hash table to hold references to arc_opcode
entries in the arc_opcodes table. This hash assumes that each mnemonic
will always appear in a contiguous blocks within the arc_opcodes table;
all ADD instruction will be together, all AND instructions will likewise
be together and so on.
The problem with this is that as different variations of arc are added,
then it is often more convenient to split instructions apart, so all the
base ADD instructions are together, but, variants of ADD specific to one
variation of arc are grouped with other instructions specific to that
arc variant. The current data structures don't support splitting the
instructions in this way.
This commit is a first step towards addressing this limitation. In this
commit the hash table that currently holds arc_opcode pointers directly,
instead holds a pointer to a new, intermediate, data structure. This
new data structure holds the pointer to the arc_opcode. In this way, we
can, in the future support having the intermediate structure hold
multiple pointers to different arc_opcode groups.
There should be no visible functional change after this commit.

An upcoming commit will add a new arc instruction flag that uses
characters that have never appeared in an arc instruction flag before.
Currently the assembler is very conservative about which characters can
or cannot appear in an instruction flag.
This commit relaxes these constraints a little. After this commit all
alpha-numeric characters are now allowed into instruction flags. This
complete set is not required for the upcoming change, however, having
this slightly larger set does not impact the assemblers ability to
correctly parse input, but does make it easier to add new flag to the
instruction table.
gas/ChangeLog:
* config/tc-arc.c (tokenize_flags): Allow greater range of

The preprocess_operands function changes the incoming list of assembler
tokens based on the assumption that the first arc_operand found will be

mnemonic.
Though this assumption is probably fine, removing this assumption, and
pushing the token change down into assemble_tokens makes the code no
more complex, and might even be easier to follow.

In tc-arc.h we redefine constants that are also defined in the
include/opcode/arc.h header file. The problem is that changing one
without changing the other resulting in strange crashes.
We could comment both locations to stress the importance of remembering
to update the other location too, or we could just include the
opcode/arc.h header file into the assembler.
Given that other targets include their opcode/ARCH.h header file, and
only having a single definition, where possible, is usually the safest
solution, that's what I switch too with this commit.

Xtensa uses it in several macros passing it a literal string, so its convenient
for the argument type to be const char *. However some of the code in
symbols.c seems to assume tc_canonicalize_symbol_name () will return a non
const pointer, and some other target's implementations even modify the
argument, so it seems best to return a char * which means casting away const on
the argument when we return it instead of another string.

parse_ldconst () takes a char ** as a in / out argument, and sometimes points
args[0] to a constant string. Then in some cases after parse_ldconst ()

For these targets its not clear how md_assemble can usefully be split up so

of casts.

various places either directly or indirectly set input_line_pointer to point at

best to add ways to generate and deal with expressions that doesn't involve

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.

frag_var () assigns its last argument to frag::fr_opcode, and it turns out
