This commit adds the _option_ of having disassembler output syntax
highlighted in objdump. This option is _off_ by default. The new
command line options are:
--disassembler-color=off # The default.
--disassembler-color=color
--disassembler-color=extended-color
I have implemented two colour modes, using the same option names as we
use of --visualize-jumps, a basic 8-color mode ("color"), and an
extended 8bit color mode ("extended-color").
The syntax highlighting requires that each targets disassembler be
updated; each time the disassembler produces some output we now pass
through an additional parameter indicating what style should be
applied to the text.
As updating all target disassemblers is a large task, the old API is
maintained. And so, a user of the disassembler (i.e. objdump, gdb)
must provide two functions, the current non-styled print function, and
a new, styled print function.
I don't currently have a plan for converting every single target
disassembler, my hope is that interested folk will update the
disassemblers they are interested in. But it is possible some might
never get updated.
In this initial series I intend to convert the RISC-V disassembler
completely, and also do a partial conversion of the x86 disassembler.
Hopefully having the x86 disassembler at least partial converted will
allow more people to try this out easily and provide feedback.
In this commit I have focused on objdump. The changes to GDB at this
point are the bare minimum required to get things compiling, GDB makes
no use of the styling information to provide any colors, that will
come later, if this commit is accepted.
This first commit in the series doesn't convert any target
disassemblers at all (the next two commits will update some targets),
so after this commit, the only color you will see in the disassembler
output, is that produced from objdump itself, e.g. from
objdump_print_addr_with_sym, where we print an address and a symbol
name, these are now printed with styling information, and so will have
colors applied (if the option is on).
Finally, my ability to pick "good" colors is ... well, terrible. I'm
in no way committed to the colors I've picked here, so I encourage
people to suggest new colors, or wait for this commit to land, and
then patch the choice of colors.
I do have an idea about using possibly an environment variable to
allow the objdump colors to be customised, but I haven't done anything
like that in this commit, the color choices are just fixed in the code
for now.

As Tom Tromey said [1]:
These files are maintained in gcc and then imported into the

The CTF variable section is an optional (usually-not-present) section in
the CTF dict which contains name -> type mappings corresponding to data
symbols that are present in the linker input but not in the output
symbol table: the idea is that programs that use their own symbol-
resolution mechanisms can use this section to look up the types of
symbols they have found using their own mechanism.
Because these removed symbols (mostly static variables, functions, etc)
all have names that are unlikely to appear in the ELF symtab and because
very few programs have their own symbol-resolution mechanisms, a special
linker flag (--ctf-variables) is needed to emit this section.
Historically, we emitted only removed data symbols into the variable
section. This seemed to make sense at the time, but in hindsight it
really doesn't: functions are symbols too, and a C program can look them
up just like any other type. So extend the variable section so that it
contains all static function symbols too (if it is emitted at all), with
types of kind CTF_K_FUNCTION.
This is a little fiddly. We relied on compiler assistance for data
symbols: the compiler simply emits all data symbols twice, once into the
symtypetab as an indexed symbol and once into the variable section.
Rather than wait for a suitably adjusted compiler that does the same for
function symbols, we can pluck unreported function symbols out of the
symtab and add them to the variable section ourselves. While we're at
it, we do the same with data symbols: this is redundant right now
because the compiler does it, but it costs very little time and lets the
compiler drop this kludge and save a little space in .o files.

The flags for the "HSA" OS ABI are properly versioned and documented on
that page. But the NONE, PAL and MESA3D OS ABIs are not well documented

encode their flags the same way as HSA v3. For example, for PAL:
c8b614cd74/llvm/lib/Target/AMDGPU/MCTargetDesc/AMDGPUTargetStreamer.cpp (L601)
So for those other OS ABIs, we read them the same as HSA v3.

Add support for the AMDGCN architecture to BFD.
This is the bare minimum to get

The specific AMDGCN models added here are a bit arbitrary, based on
what we intend to initially support in GDB. This list will need to be
updated in the future anyway. The complete up-to-date list of existing
AMDGPU models can be found here:
https://llvm.org/docs/AMDGPUUsage.html#processors
The ELF format for this architecture is documented here:

Let's hope this stays dead, but it's here as a patch separate from

The extended instructions implemented in powerpc_macros aren't used by
the disassembler. That means instructions like "sldi r3,r3,2" appear
in disassembly as "rldicr r3,r3,2,61", which is annoying since many
other extended instructions are shown.
Note that some of the instructions moved out of the macro table to the
opcode table won't appear in disassembly, because they are aliases
rather than a subset of the underlying raw instruction. If enabled,
rotrdi, extrdi, extldi, clrlsldi, and insrdi would replace all
occurrences of rotldi, rldicl, rldicr, rldic and rldimi. (Or many
occurrences in the case of clrlsldi if n <= b was added to the extract
functions.)
The patch also fixes a small bug in opcode sanity checking.

Gfortran supports namelists (a Fortran feature); it emits
DW_TAG_namelist and DW_TAG_namelist_item dies. But gdb does not
process these dies and does not support 'print' or 'ptype' commands on
namelist variables.
An attempt to print namelist variables results in gdb bailing out with
the error message as shown below.

This commit is to make the print and ptype commands work for namelist

XCOFF assembly defines the visibility using an additional argument

Currently, on 32-bit and 64-bit ARM, it seems that ld generates p_align
values of 0x10000 even if no section alignment is greater than 0x1000.
The issue is more general and probably affects other targets with multiple
page sizes.
While file layout absolutely must take 64K page size into account, that
does not have to be reflected in the p_align value. If running on a 64K
kernel, the file will be loaded at a 64K page boundary by necessity. On
a 4K kernel, 64K alignment is not needed.
The glibc loader has been fixed to honor p_align:
https://sourceware.org/bugzilla/show_bug.cgi?id=28676
similar to kernel:
commit ce81bb256a224259ab686742a6284930cbe4f1fa

fs/binfmt_elf: use PT_LOAD p_align values for suitable start address
This means that on 4K kernels, we will start to do extra work for 64K
p_align, but this pointless for pretty much all binaries (whose section
alignment rarely exceeds 16).
The minimum page size is used, instead of the maximum section alignment
due to this glibc bug:
https://sourceware.org/bugzilla/show_bug.cgi?id=28688
It has been fixed in glibc 2.35. But linker output must work on existing
glibc binaries.
1. Set p_align to the minimum page size while laying out segments aligning
to the maximum page size or section alignment. The run-time loader can
align segments to the minimum page size or above, depending on system page
size.
2. If -z max-page-size=NNN is used, p_align will be set to the maximum
page size or the largest section alignment.
3. If a section requires alignment higher than the minimum page size,
don't set p_align to the minimum page size.
4. If a section requires alignment higher than the maximum page size,
set p_align to the section alignment.
5. For objcopy, when the minimum page size != the maximum page size,
p_align may be set to the minimum page size while segments are aligned
to the maximum page size. In this case, the input p_align will be
ignored and the maximum page size will be used to align the ouput
segments.
6. Update linker to disallow the common page size > the maximum page size.
7. Update linker to avoid the common page size > the maximum page size.
8. Adjust pru_irq_map-1.d to expect p_align == sh_addralign:

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
out */po/*.pot which we don't update frequently.
The copy of cgen was with commit d1dd5fcc38ead reverted as that commit

This commit brings all the changes made by running gdb/copyright.py

This makes way for a clean 1.12 based Hypervisor Ext support.
There are no known implementors of 1.9.1 H-ext. (Per Jim, kendryte k210
is based on priv spec 1.9.1, but it seems unlikely that they implemented
H-ext).

According to the privileged spec, there are five new instructions for
svinval extension. Two of them (HINVAL.VVMA and HINVAL.GVMA) need to
enable the hypervisor extension. But there is no implementation of
hypervisor extension in mainline for now, so let's consider the related
issues later.

FreeBSD's kernel has recently added two new ELF auxiliary vector
entries. AT_FXRNG points to a root seed version for the kernel's
PRNG. Userland can use this to reseed a userland PRNG after the
kernel's PRNG has reseeded. AT_KPRELOAD is the base address of a
kernel-provided vDSO.
This change displays the proper name and description of these entries
in 'info auxv'.
include/ChangeLog:
* elf/common.h (AT_FREEBSD_FXRNG, AT_FREEBSD_KPRELOAD): Define.
We're including system headers after local headers in a bunch of
places, but this leads to conflicts when our local headers happen
to define symbols that show up in the system headers.
Use the more standard order of:
* config.h (via defs.h)
* system headers
* local library headers (e.g. bfd & libiberty)
* sim specific headers
The MOPS instructions should be used as a triple, such as:
cpyfp [x0]!, [x1]!, x2!
cpyfm [x0]!, [x1]!, x2!
cpyfe [x0]!, [x1]!, x2!
The registers should also be the same for each writeback operand.

along similar lines to the warning that we already emit for
invalid uses of MOVPRFX.

This patch adds support for FEAT_MOPS, an Armv8.8-A extension
that provides memcpy and memset acceleration instructions.
I took the perhaps controversial decision to generate the individual
instruction forms using macros rather than list them out individually.
This becomes useful with a follow-on patch to check that code follows
the correct P/M/E sequence.

libopcodes has some code to check constraints across sequences
of consecutive instructions. It was added to support MOVPRFX
sequences but is going to be useful for the Armv8.8-A MOPS
feature as well.
Currently the structure has one field to record the instruction
that started a sequence and another to record the remaining
instructions in the sequence. It's more convenient for the
MOPS code if we put the instructions into a single array instead.
No functional change intended.

When introducing this code, I forgot that we had some macros for this.
Replace some "manual" pragma diagnostic with some DIAGNOSTIC_* macros,
provided by include/diagnostics.h.
In diagnostics.h:
- Add DIAGNOSTIC_ERROR, to enable a diagnostic at error level.
- Add DIAGNOSTIC_ERROR_SWITCH, to enable -Wswitch at error level, for
both gcc and clang.
Additionally, using DIAGNOSTIC_PUSH, DIAGNOSTIC_ERROR_SWITCH and
DIAGNOSTIC_POP seems to misbehave with g++ 4.8, where we see these
errors:
CXX ada-tasks.o
/home/smarchi/src/binutils-gdb/gdb/ada-tasks.c: In function void read_known_tasks():
/home/smarchi/src/binutils-gdb/gdb/ada-tasks.c:998:10: error: enumeration value ADA_TASKS_UNKNOWN not handled in switch [-Werror=switch]
switch (data->known_tasks_kind)
^
Because of the POP, the diagnostic should go back to being disabled,
since it was disabled in the beginning, but that's not what we see
here. Versions of GCC >= 5 compile correctly.
Work around this by making DIAGNOSTIC_ERROR_SWITCH a no-op for GCC < 5.
Note that this code (already as it exists in master today) enables
-Wswitch at the error level even if --disable-werror is passed. It
shouldn't be a problem, as it's not like a new enumerator will appear
out of nowhere and cause a build error if building with future
compilers. Still, for correctness, we would ideally want to ask the
compiler to enable -Wswitch at its default level (as if the user had
passed -Wswitch on the command-line). There doesn't seem to be a way to
do this.

According the rvv spec,
https://github.com/riscv/riscv-v-spec/blob/master/vtype-format.adoc
The bits of vtype immediate from 8 to (xlen - 1) should be reserved.
Therefore, we should also dump the vtype immediate as numbers, when
they are set over 8-bits. I think this is a bug that we used to support
vediv extension and use the bit 8 and 9 of vtype, but forgot to update
the behavior when removing the vediv.
Consider the testcases,
vsetvli a0, a1, 0x700 # the reserved bit 10, 9 and 8 are used.
vsetvli a0, a1, 0x400 # the reserved bit 10 is used.
vsetvli a0, a1, 0x300 # the reserved bit 9 and 8 are used.
vsetvli a0, a1, 0x100 # the reserved bit 8 is used.
vsetivli a0, 0xb, 0x300 # the reserved bit 9 and 8 are used.
vsetivli a0, 0xb, 0x100 # the reserved bit 8 is used.
The original objdump shows the following result,
0000000000000000 <.text>:
0: 7005f557 vsetvli a0,a1,1792
4: 4005f557 vsetvli a0,a1,1024
8: 3005f557 vsetvli a0,a1,e8,m1,tu,mu
c: 1005f557 vsetvli a0,a1,e8,m1,tu,mu
10: f005f557 vsetivli a0,11,e8,m1,tu,mu
14: d005f557 vsetivli a0,11,e8,m1,tu,mu
But in fact the correct result should be,
0000000000000000 <.text>:
0: 7005f557 vsetvli a0,a1,1792
4: 4005f557 vsetvli a0,a1,1024

In preparation for the next commit, which will add GDB support for
RISC-V disassembler options, this commit restructures how the
disassembler options are managed within libopcodes.
The implementation provided here is based on this mailing list patch
which was never committed:
https://sourceware.org/pipermail/binutils/2021-January/114944.html
which in turn took inspiration from the MIPS implementation of the
same feature.
The biggest changes from the original mailing list post are:
1. The GDB changes have been split into a separate patch, and
2. The `riscv_option_args_privspec` variable, which held the valid
priv-spec values is now gone, instead we use the `riscv_priv_specs`
array from bfd/cpu-riscv.c instead.

This adds support for efi-*-aarch64 by virtue of adding a new PEI target
pei-aarch64-little. 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 aarch64 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.
With these changes the resulting file is recognized as an efi image by
third party tools:
