Problem Description
-------------------
On a Windows machine I built gdbserver, configured for the target
'x86_64-w64-mingw32', then on a GNU/Linux machine I built GDB with
support for all target (--enable-targets=all).
On the Windows machine I start gdbserver with a small test binary:
$ gdbserver 192.168.129.25:54321 C:\some\directory\executable.exe
On the GNU/Linux machine I start GDB without the test binary, and
connect to gdbserver.
As I have not given GDB the test binary, my expectation is that GDB
would connect to gdbserver and then download the file over the remote
protocol, but instead I was presented with this message:
(gdb) target remote 192.168.129.25:54321
Remote debugging using 192.168.129.25:54321
warning: C:\some\directory\executable.exe: No such file or directory.
0x00007ffa3e1e1741 in ?? ()
(gdb)
What I found is that if I told GDB where to find the binary, like
this:
(gdb) file target:C:/some/directory/executable.exe
A program is being debugged already.
Are you sure you want to change the file? (y or n) y
Reading C:/some/directory/executable.exe from remote target...
warning: File transfers from remote targets can be slow. Use "set sysroot" to access files locally instead.
Reading C:/some/directory/executable.exe from remote target...
Reading symbols from target:C:/some/directory/executable.exe...
(gdb)
then GDB would download the executable.
The Actual Issue
----------------
I tracked the problem down to exec_file_find (solib.c). The remote
target was passing an absolute Windows filename (beginning with "C:/"
in this case), but in exec_file_find GDB was failing the
IS_TARGET_ABSOLUTE_PATH call, and so was treating the filename as
relative.
The IS_TARGET_ABSOLUTE_PATH call was failing because GDB thought that
the file system kind was "unix", and as the filename didn't start with
a "/" it assumed the filename was not absolute.
But I'm connecting to a Windows target and 'target-file-system-kind'
was set to "auto", so GDB should be figuring out that the target
file-system is "dos-based".
Looking in effective_target_file_system_kind (filesystem.c), we find
that the logic of "auto" is delegated to the current gdbarch. However
in windows-tdep.c we see:
set_gdbarch_has_dos_based_file_system (gdbarch, 1);
So if we are using a Windows gdbarch we should have "dos-based"
filesystems. What this means is that after connecting to the remote
target GDB has selected the wrong gdbarch.
What's happening is that the target description sent back by the
remote target only includes the x86-64 registers. There's no
information about which OS we're on. As a consequence, GDB picks the
first x86-64 gdbarch which can handle the provided register set, which
happens to be a GNU/Linux gdbarch.
And indeed, there doesn't appear to be anywhere in gdbserver that sets
the osabi on the target descriptions. Some target descriptions do have
their osabi set when the description is created, e.g. in:
gdb/arch/amd64.c - Sets GNU/Linux osabi when appropriate.
gdb/arch/i386.c - Likewise.
gdb/arch/tic6x.c - Always set GNU/Linux osabi.
There are also some cases in gdb/features/*.c where the tdesc is set,
but these locations are only called from GDB, not from gdbserver.
This means that many target descriptions are created without an osabi,
gdbserver does nothing to fix this, and the description is returned to
GDB without an osabi included. This leaves GDB having to guess what
the target osabi is, and in some cases, GDB can get this wrong.
Proposed Solution
-----------------
I propose to change init_target_desc so that it requires an gdb_osabi
to be passed in, this will then be used to set the target_desc osabi
field.
I believe that within gdbserver init_target_desc is called for every
target_desc, so this should mean that every target_desc has an
opportunity to set the osabi to something sane.
I did consider passing the osabi into the code which creates the
target_desc objects, but that would require updating far more code, as
each target has its own code for creating target descriptions.
The approach taken here requires minimal changes and forces every
user of init_target_desc to think about what the correct osabi is.
In some cases, e.g. amd64, where the osabi is already set when the
target_desc is created, the init_target_desc call will override the
current value, however, we should always be replacing it with the same
actual value. i.e. if the target_desc is created with the osabi set
to GNU/Linux, then this should only happen when gdbserver is built for
GNU/Linux, in which case the init_target_desc should also be setting
the osabi to GNU/Linux.
The Tricky Bits
---------------
Some targets, like amd64, use a features based approach for creating
target_desc objects, there's a function in arch/amd64.c which creates
a target_desc, adds features too it, and returns the new target_desc.
This target_desc is then passed to an init_target_desc call within
gdbserver. This is the easy case to handle.
Then there are other targets which instead have a fixed set of xml
files, each of which is converted into a .dat file, which is then used
to generate a .cc file, which is compiled into gdbserver. The
generated .cc file creates the target_desc object and calls
init_target_desc on it. In this case though the target description
that is sent to GDB isn't generated from the target_desc object, but
is instead the contents of the fixed xml file. For this case the
osabi which we pass to init_target_desc should match the osabi that
exists in the fixed xml file.
Luckily, in the previous commit I copied the osabi information from
the fixed xml files into the .dat files. So in this commit I have
extended regdat.sh to read the osabi from the .dat file and use it in
the generated init_target_desc call.
The problem with some of these .dat base targets is that their fixed
xml files don't currently contain any osabi information, and the file
names don't indicate that they are Linux only (despite them currently
only being used from gdbserver for Linux targets), so I don't
currently feel confident adding any osabi information to these files.
An example would be features/rs6000/powerpc-64.xml. For now I've just
ignored these cases. The init_target_desc will use GDB_OSABI_UNKNOWN
which is the default. This means that for these targets nothing
changes from the current behaviour. But many other targets do now
pass the osabi back. Targets that do pass the osabi back are
improved with this commit.
Conclusion
----------
Now when I connect to the Windows remote the target description
returned includes the osabi name. With this extra information GDB
selects the correct gdbarch object, which means that GDB understands
the target has a "dos-based" file-system. With that correct GDB
understands that the filename it was given is absolute, and so fetches
the file from the remote as we'd like.

This function doesn't seem so useful. Use `thread_info::id::lwp`

This reverts commit 98bcde5e268ea7cd54186c5f2c27c65103218fc3. This
commit was causing build problems on at least sparc, ppc, and s390,
though I suspect some other targets might be impacted too.

then GDB would download the executable.
I eventually tracked the problem down to exec_file_find (solib.c).
The remote target was passing an absolute Windows filename (beginning
with "C:/" in this case), but in exec_file_find GDB was failing the
IS_TARGET_ABSOLUTE_PATH call, and so was treating the filename as
relative.
The IS_TARGET_ABSOLUTE_PATH call was failing because GDB thought that

a "/" it assumed the filename was not absolute.
But I'm connecting to a Windows target, my 'target-file-system-kind'
was set to "auto", so should be figuring out that my file-system is
"dos-based".
Looking in effective_target_file_system_kind (filesystem.c), we find
that the logic of "auto" is delegated to the current gdbarch. However
in windows-tdep.c we see:
set_gdbarch_has_dos_based_file_system (gdbarch, 1);
So if we are using a Windows gdbarch we should have "dos-based"
filesystems. What this means is that after connecting to the remote
target GDB has selected the wrong gdbarch.
What's happening is that the target description sent back by the
remote target only includes the x86-64 registers. There's no
information about which OS we're on. As a consequence, GDB picks the
first x86-64 gdbarch which can handle the provided register set, which

And indeed, there doesn't appear to be anywhere in gdbserver that sets
the osabi on the target descriptions, though some target descriptions
do have their osabi set when the description is created, e.g. in:
gdb/arch/amd64.c - Sets GNU/Linux osabi when appropriate.
gdb/arch/i386.c - Likewise.
gdb/arch/tic6x.c - Always set GNU/Linux osabi.
Most target descriptions are created without an osabi, gdbserver does
nothing to fix this, and the description is returned to GDB without an
osabi included.
I propose that we always set the osabi name on the target descriptions
returned from gdbserver. We could try to do this when the description
is first created, but that would mean passing extra flags into the
tdesc creation code (or just passing the osabi string in), and I don't
think that's really necessary. If we consider the tdesc creation as
being about figuring out which registers are on the target, then it
makes sense that the osabi information is injected later.
So what I've done is require the osabi name to be passed to the
init_target_desc function. This is called, I believe, for all
targets, in the gdbserver code.
Now when I connect to the Windows remote the target description
returned includes the osabi name. With this extra information GDB
selects the correct gdbarch object, which means that GDB understands
the target has a "dos-based" file-system. With that correct GDB

This commit is the result of the following actions:
- Running gdb/copyright.py to update all of the copyright headers to
include 2024,
- Manually updating a few files the copyright.py script told me to
update, these files had copyright headers embedded within the
file,
- Regenerating gdbsupport/Makefile.in to refresh it's copyright
date,
- Using grep to find other files that still mentioned 2023. If
these files were updated last year from 2022 to 2023 then I've
updated them this year to 2024.
I'm sure I've probably missed some dates. Feel free to fix them up as
you spot them.

Convert tdesc's expedite_regs to a string vector
The risc-v, loongarch, and csky gdbserver builds were broken. A use
of target_desc::expedite_regs (for each architecture) was not updated
to take account of the type change.
I've tested that this fixes the risc-v build. I haven't tested the
other architectures, but they should be fine.

Update allocate_target_description to return a target_desc_up, a
specialisation of unique_ptr.
This commit does not attempt to make use of the unique_ptr in the
best possible way, in almost all cases we immediately release the
pointer from within the unique_ptr and then continue as before.
There are a few places where it was easy to handle the unique_ptr, and
in these cases I've done that.
Everything under gdb/features/* is auto-regenerated.

This is the beginning of a series of patches that convert the linux
low targets into classes derived from linux_process_target. At the
end of the series we obtain a class hierarchy that looks like this:
process_stratum_target
^
|
|-- linux_process_target
^
|
|-- x86_target (defined in linux-x86-low)
|-- aarch64_target (defined in linux-aarch64-low)
|-- ppc_target (defined in linux-ppc-low)
|-- ...
In several cases, linux_process_target simply forwards a target op
request to a corresponding linux_target_ops function. For these
cases, the definition in linux_process_target will be removed and the
definition will be left to the deriving linux low target class; using
inheritance provides a nice and natural, object-oriented
simplification in these cases.
The series converts linux_target_ops into protected methods of
linux_process_target one by one. Throughout the series, based on the
needs, static functions defined in linux-low.cc are converted to
private methods of linux_process_target as well. This is done either
as separate patches or as integrated into a patch that convert a
particular linux_target_op into a method.
The series ends with the patch titled "gdbserver/linux-low: delete
'linux_target_ops' and 'the_low_target'".
Built and regression-tested on x86_64-linux. The following linux low
targets have been built (but not tested) via cross-compilation:
aarch64, arm, m68k, mips, ppc, riscv, s390, sh, sparc. The other
targets (bfin, cris, crisv32, ia64, m32r, nios2, tic6x, tile, xtensa)
were neither built nor tested.

Implement RISC-V/Linux support for both RV64 and RV32 systems, including
XML target description handling based on features determined, GPR and
FPR regset support including dynamic sizing of the latter, and software
breakpoint handling. Define two NT_FPREGSET regsets of a different size
matching the FPR sizes supported for generic `gdbserver' code to pick
from according to what the OS supplies.
Also handle a glibc bug where ELF_NFPREG is defined in terms of NFPREG,
however NFPREG is nowhere defined.
