This procfs.c (and friends) cleanup patch grew along a couple of lines:
* First I noticed that PR_MODEL_NATIVE is always defined now that
Solaris 10 is the minimum supported version.
* Then there was a cleanup that I'd missed when removing support for
!NEW_PROC_API, IRIX, and Tru64 UNIX: given that sysset_t is no longer
dynamic, there's no need for the special sysset_t_alloc, but we can
just use XNEW instead.
* Then I found one of those ARI warning mails on gdb-patches, discovered
how to run it myself and fixed a large number of the warnings, among
them all uses of sprintf.
I had to silence the warnings in only 3 instances of the same issue,
namely references to LDT in function names which are due to the
libthread_db API.
* Even so, there were several formatting glitches, like braces around
single statements in an if, which I chose to fix while I was at it.
The result has been tested on amd64-pc-solaris2.11 and
amd64-pc-solaris2.11.

Here we have a constant assembly instruction operand, whose value is
within the 24-bit unsigned range, to be placed in a machine instruction
such as to use the least space-consuming encoding. So the sign of that
value does not matter, because signed values are out of range and are
not supposed to appear here, and we only have this warning here because
the `X_add_number' member of `struct expressionS' is of the `offsetT'
type, which is signed.
Use an auxiliary variable of an unsigned data type then, observing that
both `offsetT' and `valueT' have the same width, as they correspond to
`bfd_signed_vma' and `bfd_vma' respectively.

Here `flag' identifies the type of a DWARF section, as used with the the
first operand to the `.dwsect' pseudo-op, and has no notion of a sign,
or for that matter being arithmetic in the first place[1]. We already
handle this correctly with the `flag' member of the `xcoff_dwsect_name'
structure, however not in the local variable used in GAS to hold the
parsed value of said `.dwsect' pseudo-op's operand.
Use an unsigned data type in GAS then too, observing that both `offsetT'

FAIL: gdb.base/auxv.exp: info auxv on gcore-created dump
The following patch fixes this by introducing the missing AT_SUN_*
values from Solaris 11.4+ <sys/auxv.h>. This lets the live and
gcore-created dump tests PASS.
I don't know yet what's the reason for those weird 'Unrecognized tag
value' warnings with native core dumps is; elfdump -n certainly doesn't
show them. However, native core dumps still need quite some work
(mostly in bfd) in this and other areas.
I've been carrying around the following patch for some time. I noticed
that both i386-sol2-nat.c and i386-v4-nat.c are Solaris-only now and it
seems confusing to carry both around.
So this patch merges i386-v4-nat.c into i386-sol2-nat.c, simplifying it
in a couple of places, like removing checks for macros that are always
defined.
Tested on 64-bit Solaris 11.5/x86 (amd64-pc-solaris2.11) and 32-bit
Solaris 11.3/x86 (i386-pc-solaris2.11) half a year ago.

When debugging with lldb, instead of having the STOP signal, we can
see that a breakpoint is not set to a proper location:
The inserted breakpoint is the one used when GDB has to stop the target
when a shared library is loaded or unloaded. The notifier address used
for adding the breakpoint is wrong thus the above failure.
This notifier address is an offset relative to dyld base address, so
the value calculation has to be updated to reflect this.
This was tested on High Sierra by trying to run a simple "hello world"

print truth_table(1,1) .OR. truth_table(2,1)
where truth_table(1,1) evaluates to true, the debugger would report that
it could not perform substring operations on this type. This patch
addresses this issue.
Investigation revealed that EVAL_SKIP was not being handled correctly
for all types serviced by the OP_F77_UNDETERMINED_ARGLIST case in
evaluate_subexp_standard. While skipping an undetermined argument list
the type is resolved to be an integer (as this is what evaluate_subexp
returns when skipping) and so it was not possible to delegate to the
appropriate case (e.g. array, function call).
The solution implemented here updates OP_VAR_VALUE to return correct
type information when skipping. This way OP_F77_UNDETERMINED_ARGLIST
can delegate the skipping to the appropriate case or routine, which
should know how to skip/evaluate the type in question.
koenig.exp was updated to include a testcase which exercises the
modified skip logic in OP_VAR_VALUE, as it falls through from
OP_ADL_FUNC.
This patch has been tested for regressions with GCC 7.3 on aarch64,
ppc64le and x86_64.

* eval.c (skip_undetermined_arglist): Skip argument list helper.

Carry the gnulib getcwd backport as a patch
Commit
e2fc52e7457 ("Fix PR gdb/23558: Use system's 'getcwd' when cross-compiling GDB")
backported some changes from a future gnulib version to our import.
However, this means that every time someone wants to change our gnulib
import (e.g. add a module), they must make sure not to include that
backported change. It also means that someone running the
update-gnulib.sh script without changes will get some diffs and wonder
why.
Instead, I suggest we carry that backport as a patch applied by the
update-gnulib.sh script after running the import tool. It will make it
clear what backport or local modification we have and should make
running update-gnulib.sh give a reproducible result.
There is a hunk in the configure file in this patch, this is because the
commit that backported the getcwd bits didn't include the re-generated
configure.

trying to use a command like gdb.execute("show commands") in Python
fails. GDB ends up trying to run the "commands" command.
The reason is that GDB gets confused with the special "commands"
command. In process_next_line, the lookup_cmd_1 function returns the
cmd_list_element representing the "commands" sub-command of "show".
Lower, we check the cmd_list_element to see if it matches various
control commands by name, including the "commands" command. This is
where we wrongfully conclude that the executed command must be
"commands", when in reality it was "show commands".
The fix proposed in this patch removes the comparisons by name, instead
comparing the cmd_list_element object by pointer with the objects
created at initialization time.

Add more methods to gdb.Progspace
There are a number of global functions in the gdb Python module which
really should be methods on Progspace. This patch adds new methods to
Progspace and then redefines these globals in terms of these new
methods.
This version has been rebased on the related changes that Simon
recently put in.
Built and regtested on x86-64 Fedora 28.

Use GNU style for metasyntactic variables in gdb
I searched for other spots that did not use the GNU style for
metasyntactic syntactic variables. This patch fixes most of the ones
I found in gdb proper. There are a few remaining in MI, but I was
unsure whether those should be touched.

Consolidate run_dump_test
This merges the three versions of run_dump_test. Improved warning
handling versus the old gas version shows up a number of tests that
need their disassembly updating:
arm-linuxeabi +FAIL: ARM v1 instructions
arm-linuxeabi +FAIL: Accepted v8-a with ARMv8.1 AdvSIMD.
arm-linuxeabi +FAIL: bl local instructions for v4t.
arm-linuxeabi +FAIL: UDF
and some that now fail due to detecting assembly warnings:
h8300-elf +FAIL: binutils-all/strip-13
h8300-elf +FAIL: binutils-all/strip-14
h8300-elf +FAIL: binutils-all/strip-15
I've generally kept the union of all run_dump_test features, except
that the ld target aliases "cfi" and "shared" have disappeared, as has
the binutils substitution of $srcdir as $scrdir/$subdir.

gas run_dump_test rename stderr and error-output
Use warning_output and error_output, like the ld version of
run_dump_test. Note that some tests used the wrong option, and this
went undetected since the gas version of run_dump_test doesn't
properly check tool error status. This patch corrects wrong options,
in preparation for a later patch that will check error status.
