For now we should always generate the elf architecture attribute both for
elf and linux toolchains, so that we could dump the objects correctly
according to the generated architecture string. This patch resolves the
problem that we probably dump an object with c.nop instructions, but
in fact the c extension isn't allowed. Consider the following case,
nelson@LAPTOP-QFSGI1F2:~/test$ cat temp.s
.option norvc
.option norelax
.text
add a0, a0, a0
.byte 0x1
.balign 16
nelson@LAPTOP-QFSGI1F2:~/test$ ~/binutils-dev/build-elf32-upstream/build-install/bin/riscv32-unknown-elf-as temp.s -o temp.o
nelson@LAPTOP-QFSGI1F2:~/test$ ~/binutils-dev/build-elf32-upstream/build-install/bin/riscv32-unknown-elf-objdump -d temp.o
temp.o: file format elf32-littleriscv
Disassembly of section .text:
00000000 <.text>:
0: 00a50533 add a0,a0,a0
4: 01 .byte 0x01
5: 00 .byte 0x00
6: 0001 nop
8: 00000013 nop
c: 00000013 nop
nelson@LAPTOP-QFSGI1F2:~/test$ ~/binutils-dev/build-elf32-upstream/build-install/bin/riscv32-unknown-elf-readelf -A temp.o
Attribute Section: riscv
File Attributes
Tag_RISCV_arch: "rv32i2p0_m2p0_a2p0_f2p0_d2p0"
The c.nop at address 0x6 is generated for alignment, but since the rvc isn't
allowed for this object, dump it as a c.nop instruction looks wrong. After
applying this patch, I get the following result,
nelson@LAPTOP-QFSGI1F2:~/test$ ~/binutils-dev/build-elf32-upstream/build-install/bin/riscv32-unknown-elf-objdump -d temp.o
temp.o: file format elf32-littleriscv
Disassembly of section .text:
00000000 <.text>:
0: 00a50533 add a0,a0,a0
4: 01 .byte 0x01
5: 00 .byte 0x00
6: 0001 .2byte 0x1
8: 00000013 nop
c: 00000013 nop
For the current objdump, we dump data to .byte/.short/.word/.dword, and
dump the unknown or unsupported instructions to .2byte/.4byte/.8byte, which
respectively are 2, 4 and 8 bytes instructions. Therefore, we shouldn't
dump the 0x0001 as a c.nop instruction in the above case, we should dump
it to .2byte 0x1 as a unknown instruction, since the rvc is disabled.
However, consider that some people may use the new objdump to dump the old
objects, which don't have any elf attributes. We usually set the default
architecture string to rv64g by bfd/elfxx-riscv.c:riscv_set_default_arch.
But this will cause rvc instructions to be unrecognized. Therefore, we
set the default architecture string to rv64gc for disassembler, to keep
the previous behavior.
This patch pass the riscv-gnu-toolchain gcc/binutils regressions for
rv32emc-elf, rv32gc-linux, rv32i-elf, rv64gc-elf and rv64gc-linux
toolchains. Also, tested by --enable-targets=all and can build
riscv-gdb successfully.

If built as a shared library, libopcodes has a load-time dependency on
libbfd, which is recorded in the dynamic section, however without a
corresponding RPATH entry for the directory to find libbfd in. This
causes loading to fail whenever libbfd is only pulled by libopcodes
indirectly and libbfd has been installed in a directory that is not in
the dynamic loader's search path.
It does not happen with the programs included with binutils or GDB,
because they all also pull libbfd when using libopcodes, but it can
happen with external software, e.g.:
$ gdbserver --help
gdbserver: error while loading shared libraries: libbfd-[...].so: cannot open shared object file: No such file or directory
$
(not our `gdbserver').
Indirect dynamic dependencies are handled by libtool automatically by
adding RPATH entries as required, however our setup for libopcodes
prevents this from happening by linking in libbfd with an explicit file
reference sneaked through to the linker directly behind libtool's back
via the `-Wl' linker command-line option rather than via `-l' combined
with a suitable library search path specified via `-L', as it would be
usually the case, or just referring to the relevant .la file in a fully
libtool-enabled configuration such as ours.
According to an observation in the discussion back in 2007[1][2][3] that
has led to the current arrangement it is to prevent libtool from picking
up the wrong version of libbfd. It does not appear to be needed though,
not at least with our current libtool incarnation, as directly referring
`libbfd.la' does exactly what it should, as previously suggested[4], and
with no link-time reference to the installation directory other than to
set RPATH. Uninstalled version of libopcodes has libbfd's build-time
location prepended to RPATH too, as also expected.
Use a direct reference to `libbfd.la' then, making the load error quoted
above go away. Alternatively `-L' and `-l' could be used to the same
effect, but it seems an unnecessary complication and just another way to
circumvent rather than making use of libtool.

When the RISC-V disassembler encounters an unknown instruction, it
currently just prints the value of the bytes, like this:
Dump of assembler code for function custom_insn:
0x00010132 <+0>: addi sp,sp,-16
0x00010134 <+2>: sw s0,12(sp)
0x00010136 <+4>: addi s0,sp,16
0x00010138 <+6>: 0x52018b
0x0001013c <+10>: 0x9c45
My proposal, in this patch, is to change the behaviour to this:
Dump of assembler code for function custom_insn:
0x00010132 <+0>: addi sp,sp,-16
0x00010134 <+2>: sw s0,12(sp)

0x00010138 <+6>: .4byte 0x52018b
0x0001013c <+10>: .2byte 0x9c45
Adding the .4byte and .2byte opcodes. The benefit that I see here is
that in the patched version of the tools, the disassembler output can
be fed back into the assembler and it should assemble to the same
binary format. Before the patch, the disassembler output is invalid
assembly.
I've started a RISC-V specific test file under binutils so that I can
add a test for this change.

With a gdb build with --enable-targets=all, we have 2 arch-specific failures
in selftest print_one_insn:
...
$ gdb -q -batch a.out -ex "maint selftest print_one_insn" 2>&1 \
| grep "Self test failed: arch "
Self test failed: arch armv8.1-m.main: self-test failed at \
disasm-selftests.c:165
Self test failed: arch arm_any: self-test failed at disasm-selftests.c:165
$
...
During the first failed test, force_thumb is set to true, and remains so until
and during the second test, which causes the second failure.
Fix this by resetting force_thumb to false in parse_arm_disassembler_options,
such that we get just one failure:
...
$ gdb -q -batch a.out -ex "maint selftest print_one_insn" 2>&1 \
| grep "Self test failed: arch "
Self test failed: arch armv8.1-m.main: self-test failed at \
disasm-selftests.c:165
$
...
Tested on x86_64-linux.
The disassembler has support to pretty print values created by an lui/addi
pair, but there is no support for addiw. There is also no support for
c.addi and c.addiw. This patch extends the pretty printing support to
handle these 3 instructions in addition to addi. Existing testcases serve
as tests for the new feature.

Similar to ARM/AARCH64, we add mapping symbols in the symbol table,
to mark the start addresses of data and instructions. The $d means
data, and the $x means instruction. Then the disassembler uses these
symbols to decide whether we should dump data or instruction.
Consider the mapping-04 test case,
$ cat tmp.s
.text
.option norelax
.option norvc
.fill 2, 4, 0x1001
.byte 1
.word 0
.balign 8
add a0, a0, a0
.fill 5, 2, 0x2002
add a1, a1, a1
.data
.word 0x1 # No need to add mapping symbols.
.word 0x2
$ riscv64-unknown-elf-as tmp.s -o tmp.o
$ riscv64-unknown-elf-objdump -d tmp.o
Disassembly of section .text:
0000000000000000 <.text>:
0: 00001001 .word 0x00001001 # Marked $d, .fill directive.
4: 00001001 .word 0x00001001
8: 00000001 .word 0x00000001 # .byte + part of .word.
c: 00 .byte 0x00 # remaining .word.
d: 00 .byte 0x00 # Marked $d, odd byte of alignment.
e: 0001 nop # Marked $x, nops for alignment.
10: 00a50533 add a0,a0,a0
14: 20022002 .word 0x20022002 # Marked $d, .fill directive.
18: 20022002 .word 0x20022002
1c: 2002 .short 0x2002
1e: 00b585b3 add a1,a1,a1 # Marked $x.
22: 0001 nop # Section tail alignment.
24: 00000013 nop
* Use $d and $x to mark the distribution of data and instructions.
Alignments of code are recognized as instructions, since we usually
fill nops for them.
* If the alignment have odd bytes, then we cannot just fill the nops
into the spaces. We always fill an odd byte 0x00 at the start of
the spaces. Therefore, add a $d mapping symbol for the odd byte,
to tell disassembler that it isn't an instruction. The behavior
is same as Arm and Aarch64.
The elf/linux toolchain regressions all passed. Besides, I also
disable the mapping symbols internally, but use the new objudmp, the
regressions passed, too. Therefore, the new objudmp should dump
the objects corretly, even if they don't have any mapping symbols.

As discussed previously, a.out support is now quite deprecated, and in
some cases removed, in both Binutils itself and NetBSD, so this legacy
default makes little sense. `netbsdelf*` and `netbsdaout*` still work
allowing the user to be explicit about there choice. Additionally, the
configure script warns about the change as Nick Clifton requested.
One possible concern was the status of NetBSD on NS32K, where only a.out
was supported. But per [1] NetBSD has removed support, and if it were to
come back, it would be with ELF. The binutils implementation is
therefore marked obsolete, per the instructions in the last message.
With that patch and this one applied, I have confirmed the following:
--target=i686-unknown-netbsd
--target=i686-unknown-netbsdelf
builds completely
--target=i686-unknown-netbsdaout
properly fails because target is deprecated.
--target=vax-unknown-netbsdaout builds completely except for gas, where
the target is deprecated.

Intel AVX512 FP16 instructions use maps 3, 5 and 6. Maps 5 and 6 use 3 bits
in the EVEX.mmm field (0b101, 0b110). Map 5 is for instructions that were FP32
in map 1 (0Fxx). Map 6 is for instructions that were FP32 in map 2 (0F38xx).
There are some exceptions to this rule. Some things in map 1 (0Fxx) with imm8
operands predated our current conventions; those instructions moved to map 3.
FP32 things in map 3 (0F3Axx) found new opcodes in map3 for FP16 because map3
is very sparsely populated. Most of the FP16 instructions share opcodes and
prefix (EVEX.pp) bits with the related FP32 operations.
Intel AVX512 FP16 instructions has new displacements scaling rules, please refer
to the public software developer manual for detail information.
