git commit 211dc24b87 removed most sh5 and sh64 SuperH support, after
they were obsoleted by git commit 2b213129c5. This patch removes a
few remaining pieces that should have gone with 211dc24b87.

I recently learned that move constructors generally should be marked
"noexcept". This ensures that standard containers will move objects
when possible, rather than copy them.
This patch fixes the cases I could find. Note that implicitly-defined
or defaulted move constructors will automatically do what you'd
expect; that is, they are noexcept if all the members have noexcept
move constructors.
While doing this, I noticed a couple of odd cases where the move
constructor seemed to assume that the object being constructed could
have state requiring destruction. I've fixed these as well. See
completion_result and scoped_mmap.

symbol types N_TEXT etc. were #undef'd and then #define'd with new values. But N_STAB was not changed even though the new value for N_EXT overlapped with it. This caused aout_link_write_symbols() to treat global symbols referenced in the source but defined in a linker script as undefined.
Separately, in translate_symbol_table() the 16-bit symbol values were sign extended to unsigned long (e.g., 64 bits) when they really should be treated as unsigned so the value remains 16 bits.
PR 25828
* pdp11.c (N_STAB): Modify value to avoid conflict with N_EXT
causing globals from linker script to be treated as debug symbols.
(translate_symbol_table): Don't sign-extend symbol values from 16

This patch implements the TSB instructions:
https://developer.arm.com/docs/ddi0596/f/base-instructions-alphabetic-order/
tsb-csync-trace-synchronization-barrier
Since TSB and PSB both use the same (and only) argument "CSYNC", this patch
reuses it for TSB. However, the same argument would imply different value
for CRm:Op2 which are anyway fixed values, so I have diverted the
inserter/extracter function to dummy versions instead of the "hint" version.
The operand checker part still uses the existing infratructure for
AARCH64_OPND_BARRIER_PSB to make sure the operand is parsed correctly.

This is another one where not cleaning up sufficiently after
processing one file can lead to errors when processing the next file.
We have ngnuchains non-zero but gnuchains NULL in the following:
off < ngnuchains && (gnuchains[off] & 1) == 0

This patch is aimed at fixing a number of oss-fuzz segfaults that
don't reproduce reliably with their current infrastructure, the
problem being that one invocation of readelf is effectively being run
on multiple object files. I believe that these segfaults could be
reliably reproduced with just two fuzzed objects being presented to
readelf, but those inputs are currently not identified by oss-fuzz.
So there is some guesswork involved in this patch. The idea here is
to clear stashed data such as symtab_shndx_list that is processed
using section header info, at the same time that header info is
cleared.
* readelf.c (process_section_headers): Free dynamic symbols etc.
earlier.

This fixes two leaks found in the new code supporting display of
dynamic symbols retrieved via dynamic tags.
* readelf.c (get_num_dynamic_syms): Formatting. Don't return
on error without freeing.
(process_dynamic_section): Don't recreate dynamic symbols from
dynamic tag info when the dynamic symbols have already been
read via section headers.

Stripping .rela.branch_lt is easy enough but messes with the

When I removed init_w32_command_list, I weirdly neglected to see if it
was called anywhere else. This patch restores the function, which is
called from windows-nat.c. Sorry about the breakage.
Is it possible to have a windows-native gdb that isn't also using
windows-tdep?
Anyway, I'm checking this in.

Two ld tests currently XPASS on 64-bit Solaris/SPARC:
XPASS: ld-elf/warn1
XPASS: ld-elf/warn2
They were xfail'ed on Solaris/SPARCv9 back in 2005
https://sourceware.org/pipermail/binutils/2005-February/039268.html
but obviously this no longer appplies.
Fixed by removing the xfail's.
Tested on sparcv9-sun-solaris2.11 and sparc-sun-solaris2.11.
* testsuite/ld-elf/warn1.d: Don't xfail on 64-bit Solaris/SPARC.

This changes get_objfile_arch to be a new inline method,
objfile::arch.
To my surprise, this function came up while profiling DWARF psymbol
reading. Making this change improved performance from 1.986 seconds
to 1.869 seconds. Both measurements were done by taking the mean of
10 runs on a fixed copy of the gdb executable.

Currently there are many prefix commands that do nothing but call
either help_list or cmd_show_list. I happened to notice that one such
call, for "set print type", used the wrong command list parameter,
causing incorrect output.
Rather than fix this bug in isolation, I decided to eliminate this
possibility by adding two new ways to add prefix commands, which
simply route the call to help_list or cmd_show_list, as appropriate.
This makes it impossible for a mismatch to occur.
In some cases, a bit of output was removed; however, I don't think
this output in general was very useful. It seemed redundant with
what's already printed by help_list. A representative example is this
hunk, removed from ada-lang.c:
- printf_unfiltered (_(\
-"\"set ada\" must be followed by the name of a setting.\n"));
This simplified the CLI style set/show commands quite a bit, and
allowed the deletion of a macro.
This also cleans up some unusual code in windows-tdep.c.
Tested on x86-64 Fedora 30. Note that I have no way to build the
go32-nat.c change.

When a warning is displayed, it isn't clear to the user which file is
the cause of the warning. Add the filename in there. Remove the
"Failed to parse .idata section" part, since the .idata section is
always mentioned one way or another anyway, so it just contributes to
make the message longer than it needs to be.

.idata section
When loading the file C:\Windows\SysWOW64\msvcrt.dll, taken from a
Windows 10 system, into GDB, we get the following warning:
warning: Failed to parse .idata section: name's virtual address (0x0) is outside .idata section's range [0xb82b8, 0xb97f0[.
This uncovers an issue with how we parse the import table, part of the
.idata section. Right now, we assume that the import table is located
at the beginning of the section. That was the case in everything I had
tried so far, but this file is an example where that's not true.
We need to compute the offset of the import table within the .idata
section, and start there, instead of at the beginning of the .idata
section. Using the file mentioned above, this is the values we have to
work with:
A) bfd_section_vma (idata_section) 101b8000
B) Import table's virtual address b82b8
C) Image base 10100000
The virtual address that BFD returns us for the section has the image
base applied, so we need to subtract it first. The offset of the table
in the section is therefore:
B - (A - C)
This patch implements that.
gdb/ChangeLog:
* windows-tdep.c (is_linked_with_cygwin_dll): Consider case where
import table is not at beginning of .idata section.

Currently, while the program_space's ctor adds the new pspace to the
pspaces list, the destructor doesn't remove the pspace from the pspace
list. Instead, you're supposed to use delete_program_space, to both
remove the pspace from the list, and deleting the pspace.
This patch eliminates delete_program_space, and makes the pspace dtor
remove the deleted pspace from the pspace list itself, i.e., makes the
dtor do the mirror opposite of the ctor.
I found this helps with a following patch that will allocate a mock
program_space on the stack. It's easier to just let the regular dtor
remove the mock pspace from the pspace list than arrange to call
delete_program_space instead of the pspace dtor in that situation.
While at it, move the ctor/dtor intro comments to the header file, and
make the ctor explicit.

Simon pointed out that the windows-nat sharing series broke the Cygwin
build. This patch fixes the problem, by moving the Cygwin-specific
code to a new handler function. This approach is taken because this
code calls find_pc_partial_function, which isn't available in
gdbserver.

...
Looking at the .gdb_index section contents using objdump --dwarf=gdb_index, we
have:
...
CU table:
[ 0] 0x0 - 0x2d
[ 1] 0x2e - 0xa4
[ 2] 0xa5 - 0xc6
[ 3] 0xf7 - 0x126
[ 4] 0x127 - 0x2de
[ 5] 0x2df - 0x300
Address table:
00000000004004a7 00000000004004b2 4
Symbol table:
[489] main: 4 [global, function]
...
We see that both the main symbol, and main address range map to CU 4, which has
offset range 0x127 - 0x2de, while main actually is contained in CU 3 at offset
range 0xf7 - 0x126.
This is caused by this continue in write_gdbindex, which triggers for the PU:
...
/* CU of a shared file from 'dwz -m' may be unused by this main file.
It may be referenced from a local scope but in such case it does not
need to be present in .gdb_index. */
if (psymtab == NULL)
continue;
...
The continue causes the PU to be skipped in the CU table (we can see that the
PU offset range 0xc7-0xf6 is missing) but the references are not taking that
into account.
I've tried fixing this in the optimal way, by updating the references, but ran
into trouble when follow_die_offset tries to find the CU for the inter-CU
ref. Because the PU is missing from the CU table,
dwarf2_find_containing_comp_unit bisects to the wrong CU.
Fix this by not skipping the PU in the CU table.
Build and reg-tested on x86_64-linux, with native and target boards
cc-with-gdb-index, cc-with-dwz and cc-with-dwz-m.

Information about the deprecated function can be found here:

Specifically, with regard to PyEval_InitThreads(), it says:
The PyEval_InitThreads() and PyEval_ThreadsInitialized() functions
are now deprecated and will be removed in Python 3.11. Calling
PyEval_InitThreads() now does nothing. The GIL is initialized by
Py_Initialize() since Python 3.7. (Contributed by Victor Stinner
in bpo-39877.)
I chose to disable the call with a #if test using PY_VERSION_HEX.
There is precedent for use of PY_VERSION_HEX; it's used in two places
in python-internal.h. I noticed that under certain circumstances
python-internal.h defines PyEval_InitThreads to be nothing, which
accomplishes the same thing. I considered doing something similar for
this case, but decided against it because, at some point in the future,
the presence of PyEval_InitThreads() without some explanation will be
confusing to a reader who won't be able to find PyEval_InitThreads in
the current (future for us) Python API. IMO, use of the #if along
with an accompanying comment seemed more straightforward.
gdb/ChangeLog:
* python/python.c (do_start_initialization): Don't call
PyEval_InitThreads for Python 3.9 and beyond.
