This changes readelf output a little, removing the 0x prefix on hex
output when the value is 0, except in cases where a fixed field
width is shown. %#010x is not a good replacement for 0x%08x.
This adds support for efi-loongarch64 by virtue of adding a new PEI target
pei-loongarch64. This is not a full target and only exists to support EFI at
this time.
This means that this target does not support relocation processing and is mostly
a container format. This format has been added to elf based loongarch64 targets
such that efi images can be made natively on Linux.
However this target is not valid for use with gas but only with objcopy.
We should't limit addresses to 32-bits for 64-bit vma, otherwise there will be
"RVA truncated" error when using objcopy on loongarch64.
With these changes the resulting file is recognized as an efi image.
Any magic number is based on the Microsoft PE specification [1].
The test results are as follows:
$ make check-binutils RUNTESTFLAGS='loongarch64.exp'
PASS: Check if efi app format is recognized
$ objdump -h -f tmpdir/loongarch64copy.o
tmpdir/loongarch64copy.o: file format pei-loongarch64

Correct issues with INSN2_ALIAS annotation for branch instructions:
- regular MIPS BEQZ/L and BNEZ/L assembly instructions are idioms for
BEQ/L and BNE/L respectively with the `rs' operand equal to $0,
- microMIPS 32-bit BEQZ and BNEZ assembly instructions are idioms for
BEQ and BNE respectively with the `rt' operand equal to $0,
- regular MIPS BAL assembly instruction is an idiom for architecture
levels of up to the MIPSr5 ISA and a machine instruction on its own
from the MIPSr6 ISA up.
Add missing annotation to BEQZ/L and BNEZ/L accordingly then and add a
new entry for BAL for the MIPSr6 ISA, correcting a disassembly bug:
$ mips-linux-gnu-objdump -m mips:isa64r6 -M no-aliases -d bal.o
bal.o: file format elf32-tradlittlemips
Disassembly of section .text:
00000000 <foo>:

...
$
Add test cases accordingly.

PowerPC64 takes a more traditional approach to DT_RELR than x86. Count

the usual places but not doing so when enable_dt_relr. DT_RELR is
sized in the existing ppc stub relaxation machinery, run via the
linker's ldemul_after_allocation hook. DT_RELR is output in the same
function that writes ppc stubs, run via ldemul_finish.

As pre-approved by Alan in

and I believe people have run into getting testsuite failures for
test-environments with "long" directory names, at least once more
since that time. Enough. I grepped the gas, binutils and ld
testsuites for "CU:" to catch target-specific occurrences, but I
noticed none. I chose to remove "CU:" on the objdump tests instead of
changing options to get the wide format, so as to keep the name of the
test consistent with actual options; but added it to the readelf
options for the gas test as I believe the "CU:" format is preferable.
Tested for cris-elf and native x86_64-pc-linux-gnu.
binutils:
* dwarf.c (display_debug_lines_decoded): Don't check the
string length of the directory, instead emit the "CU: dir/name"
format only if wide output is requested.
* testsuite/binutils-all/dw5.W, testsuite/binutils-all/objdump.WL:
Adjust accordingly.
gas:
* testsuite/gas/elf/dwarf-5-loc0.d: Add -W to readelf options.
In many ar implementations (FreeBSD, elfutils, etc), -T has the X/Open
System Interface specified semantics. Therefore -T for thin archives is
not recommended for portability. -T is deprecated without diagnostics.

The result of running etc/update-copyright.py --this-year, fixing all
the files whose mode is changed by the script, plus a build with
--enable-maintainer-mode --enable-cgen-maint=yes, then checking

The copy of cgen was with commit d1dd5fcc38ead reverted as that commit
breaks building of bfp opcodes files.

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.

too. This was all supposed to work with the testsuite .exp files
using CC for the target compiler, and CC_FOR_HOST for the host
compiler, with the makefiles passing CC=$CC_FOR_TARGET and
CC_FOR_HOST=$CC to the runtest invocation.
One exception to the rule of using CC_FOR_TARGET is the native-only ld
bootstrap test, which uses the newly built ld to link a copy of
itself. Since the files being linked were created with the host
compiler, the boostrap test should use CC and CFLAGS, in case some
host compiler option provides needed libraries automatically.
However, bootstrap.exp used CC where it should have used CC_FOR_HOST.
I set about fixing that problem, then decided that playing games in
the makefiles with CC was a bad idea. Not only is it confusing, but
other dejagnu code knows about CC_FOR_TARGET. See dejagnu/target.exp.
So this patch gets rid of the makefile variable renaming and changes
all the .exp files to use the correct _FOR_TARGET variables.
CC_FOR_HOST and CFLAGS_FOR_HOST disappear. A followup patch will
correct bootstrap.exp to use CFLAGS, and a number of other things I
noticed.

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.

netbsdpe was deprecated in c2ce831330.
Since then, a release has passed (2.37), and it was marked obselete in
5c9cbf07f3. Unless I am mistaken, that
means we can now remove support altogether.
All branches in the "active" code are remove, and the target is
additionally marked as obsolete next to the other removed ones for
libbfd and gdb.
Per [1] from the NetBSD toolchain list, PE/COFF support was removed a
decade ago. Furthermore, the sole mention of this target in the binutils
commit history was in 2002. Together, I'm led to believe this target
hasn't seen much attention in quite a while.

Since gcc commit, 3c70b3ca1ef58f302bf8c16d9e7c7bb8626408bf, we now enable
elf attributes for all riscv targets by default in gcc. Therefore, I
think binutils should have the same behavior, in case users are writing
assembly files. If --enable-default-riscv-attribute isn't set, then we
enable the elf attributes for all riscv targets by default.

I finally found time to teach readelf to identify PIEs in the file
header display and program header display. So in place of
"DYN (Shared object file)" which isn't completely true, show
"DYN (Position-Independent Executable file)".
It requires a little bit of untangling code in readelf due to
process_program_headers setting up dynamic_addr and dynamic_size,
needed to scan .dynamic for the DT_FLAGS_1 entry, and
process_program_headers itself wanting to display the file type in
some cases. At first I modified process_program_header using a
"probe" parameter similar to get_section_headers in order to inhibit
output, but decided it was cleaner to separate out
locate_dynamic_sections.

The CP0 control register set has never been defined, however encodings
for the CFC0 and CTC0 instructions remained available for implementers
up until the MIPS32 ISA declared them invalid and causing the Reserved
Instruction exception[1]. Therefore we handle them for both assembly
and disassembly, however in the latter case the names of CP0 registers
from the regular set are incorrectly printed if named registers are
requested. This is because we do not define separate operand classes
for coprocessor regular and control registers respectively, which means
the disassembler has no way to tell the two cases apart. Consequently
nonsensical disassembly is produced like:
cfc0 v0,c0_random
Later the MIPSr5 ISA reused the encodings for XPA ASE MFHC0 and MTHC0
instructions[2] although it failed to document them in the relevant
opcode table until MIPSr6 only.
Correct the issue then by defining a new register class, OP_REG_CONTROL,
and corresponding operand codes, `g' and `y' for the two positions in
the machine instruction a control register operand can take. Adjust the
test cases affected accordingly.
While at it swap the regular MIPS opcode table "cfc0" and "ctc0" entries
with each other so that they come in the alphabetical order.

This is because the test cases rely on these ASEs being disabled for
disassembly by default and expect instructions belonging to these ASEs
not to be shown unless explicitly enabled. The `mips-xpa-virt-4' test
case passes regardless, but we want it to verify the explicit options do
work, so use the `mips:3000' machine to set the defaults there as well.
