AArch64: Fix objdump tests
The newly added objdump -S tests check for source line mapping of a static
variable. But the test doesn't dump any data sections so this should never
pass.
This changes the test to dump all sections so the source mapping can be found.

bfd_section_* macros
This large patch removes the unnecessary bfd parameter from various
bfd section macros and functions. The bfd is hardly ever used and if
needed for the bfd_set_section_* or bfd_rename_section functions can
be found via section->owner except for the com, und, abs, and ind
std_section special sections. Those sections shouldn't be modified
anyway.
The patch also removes various bfd_get_section_<field> macros,
replacing their use with bfd_section_<field>, and adds
bfd_set_section_lma. I've also fixed a minor bug in gas where
compressed section renaming was done directly rather than calling
bfd_rename_section. This would have broken bfd_get_section_by_name
and similar functions, but that hardly mattered at such a late stage
in gas processing.

[gdb/testsuite] Handle unreachable network in server-connect.exp

FAIL: gdb.server/server-connect.exp: tcp6: connect to gdbserver using tcp6:::1
FAIL: gdb.server/server-connect.exp: tcp6-with-brackets: connect to gdbserver \

FAIL: gdb.server/server-connect.exp: udp6-with-brackets: connect to gdbserver \

The FAIL is caused by the fact that the ipv6 loopback address is not available:
...
PASS: gdb.server/server-connect.exp: tcp6: start gdbserver

A program is being debugged already. Kill it? (y or n) y^M
tcp6:::1:2347: Network is unreachable.^M
(gdb) FAIL: gdb.server/server-connect.exp: tcp6: connect to gdbserver using tcp6:::1
...
This should be marked UNSUPPORTED rather than FAIL.
Furthermore, the test-case takes about 4 minutes, because the 'Network is
unreachable' response is not explicitly handled in gdb_target_cmd, so instead
it runs into the timeout case.
Fix this by handling the 'Network is unreachable' response as UNSUPPORTED.
This reduces testing time from 4 minutes to about 2 seconds.

Give a name to the TUI SingleKey keymap
Readline 8.0 has a feature that lets an application name a keymap.
This in turn makes it simpler for users to bind keys in keymaps in
their .inputrc.
This patch gives a name to the TUI SingleKey keymap, so that
additional bindings can be made there. For example:
$if gdb
set keymap SingleKey
"X": "echo hello\\n\n"
$endif
The call to rl_initialize, in tui_initialize_readline, had to be
removed so that .inputrc was not read too early. Note that Readline
explicitly documents that this call is not needed.

binutils: doc: remove stale things from Makefile
The `install-data-local: install-info` part: the comment refers to when
the Makefile had the cygnus option. It no longer uses that, so the info
file should get installed without that rule. I verified that `make
install` still installed $(prefix)/share/info/binutils.info.
The `DISTCLEANFILES` part: the comment talks about Automake 1.9, we are
using 1.15.1, which doesn't appear to have this problem. binutils.info
is built fine without this snippet.
Note: with my automake 1,15.1 (built from source), I get a spurious diff
in Makefile.in, where the
runstatedir = @runstatedir@
line gets removed. I am not sure why, but I haven't included it.

Re-generate many configure and Makefile.in files
I get some spurious changes when running autoconf/automake for various
projects in the tree. This is likely because they were generated using
distro-patched tools last time.
I ran `autoreconf -f` in the various automake projects of the
binutils-gdb tree, and this is the result. The tools I am using have
been compiled from source, from the upstream release.

gdb: Look for compilation directory relative to directory search path
The 'directory' command allows the user to provide a list of filesystem
directories in which to search for source code. The directories in this
search path are used as the base directory for the source filename from
the debug information (DW_AT_name). Thus the directory search path
provides alternatives to the existing compilation directory from the
debug information (DW_AT_comp_dir). Generally speaking, DW_AT_name
stores the filename argument passed to the compiler (including any
directory components), and DW_AT_comp_dir stores the current working
directory from which the compiler was executed. For example:
$ cd /path/to/project/subdir1
$ gcc -c a/test.c -g
The corresponding debug information will look like this:
DW_AT_name : a/test.c
DW_AT_comp_dir : /path/to/project/subdir1
When compiling with the -fdebug-prefix-map GCC option, the compilation
directory can be arbitrarily rewritten. In the above example, we may
rewrite the compilation directory as follows:
$ gcc -c a/test.c -g -fdebug-prefix-map=/path/to/project=
In this case, the corresponding debug information will look like:
DW_AT_name : a/test.c
DW_AT_comp_dir : /subdir1
This prevents GDB from finding the corresponding source code based on
the debug information alone. In some cases, a substitute-path command
can be used to re-map a consistent prefix in the rewritten compilation
directory to the real filesystem path. However, there may not be a
consistent prefix remaining in the debug symbols (for example in a
project that has source code in many subdirectories under the project's
root), thereby requiring multiple substitute-path rules. In this case,
it is easier to add the missing prefix to the directory search path via
the 'directory' command.
The function find_and_open_source currently searches in:
SEARCH_PATH/FILENAME
where SEARCH_PATH corresponds to each individual entry in the directory
search path (which is guaranteed to contain the compilation directory
from the debug information, as well as the current working directory).
FILENAME corresponds to the source filename (DW_AT_name), which may have
directory components in it. In addition, GDB searches in:
SEARCH_PATH/FILE_BASENAME
where FILE_BASENAME is the basename of the DW_AT_name entry.
This change modifies find_and_open_source to additionally search in:
SEARCH_PATH/COMP_DIR/FILENAME
where COMP_DIR is the compilation directory from the debug symbols. In
the example given earlier, running:
(gdb) directory /path/to/project
will now allow GDB to correctly locate the source code from the debug
information.

gdb: Catch exceptions when accessing source cache
The source_cache::get_line_charpos function can currently throw an
exception if the source file is missing, which doesn't match the
expected behaviour documented in the functions header file. The
documented behaviour is to return false on failure, and this is how
the function appears to be used throughout GDB.
I spotted this in the 'info source' command, currently for a missing
source file you'll see something like this:
(gdb) info source
Current source file is /path/to/src/file.c
Compilation directory is /path/to/build/
/path/to/src/file.c: No such file or directory.
(gdb)
After this patch we see this:
(gdb) info source
Current source file is /path/to/src/file.c
Compilation directory is /path/to/build/
Source language is c.
Producer is COMPILER VERSION AND FLAGS.
Compiled with DWARF 2 debugging format.
Does not include preprocessor macro info.
We don't currently indicate that the source file can't be found, and

(Ada) do not print Ada task names in quotes in "info tasks" output
A recent change enhanced a couple of notifications about Ada tasks to
include the task's name in addition to the task's number. That change
also modified the output of the "info tasks" when printing the detailed
information of one given task. I believe this change was unintentionally
left over from the initial version after it was decided that quoting
the task's name should not be done. This patch therefore undoes this
part of the patch.

gdb: Have 'maint info sections' print all sections again

We lost the section index numbers, but more importantly, we lost the
information about the .debug* sections. We also gained entries for
the "fake" sections *COM*, *UND*, *ABS*, and *IND*.
I noticed this when running:
make check-gdb RUNTESTFLAGS="--target_board=cc-with-gdb-index gdb.base/maint.exp"
As this test relies on looking in the 'maint info sections' output to
see if we have a .debug_names or .gdb_index section, and these are
debug sections so they no longer show up in the 'main info sections'
output, the gdb.base/maint.exp test fails.
This commit restores the old behaviour while keeping the important
change that the above commit introduced, the addresses printed for
sections are the relocated addresses where appropriate. The above
commit mentions using this test:
make check-gdb RUNTESTFLAGS="CFLAGS_FOR_TARGET='-pie' gdb.base/compare-sections.exp"
And this still passes after this commit.
The output for 'maint info sections' now looks like this:

This is basically as it was before, except that the index numbers are
now padded so the section information all lines up.
When GDB has relocated a section then the relocated addresses will be
printed, otherwise the non-relocated addresses from the bfd will be
printed.
I've added a test to gdb.base/maint.exp to do some basic validation of
the output format.

gdb: Don't fault for 'maint print psymbols' when using an index
I found that these tests:
make check-gdb RUNTESTFLAGS="--target_board=cc-with-gdb-index gdb.base/maint.exp"
make check-gdb RUNTESTFLAGS="--target_board=cc-with-debug-names gdb.base/maint.exp"
were causing GDB to segfault. It turns out that this test runs this
command:
maint print psymbols -pc main /path/to/some/file
which tries to lookup the partial_symtab for 'main'. The problem is
that there is no partial_symtab for 'main' as we are using the
.gdb_index or .debug_names instead of partial_symtabs.
What happens is that maintenance_print_symbols calls
find_pc_sect_psymtab, which looks for the partial_symtab in the
objfile's objfile->partial_symtabs->psymtabs_addrmap.
This is a problem because when we are using the indexes
psymtabs_addrmap is reused to hold things other than partial_symtabs,
this can be seen in dwarf2read.c in create_addrmap_from_index and
create_addrmap_from_aranges. If we then lookup in psymtabs_addrmap we
end up returning a pointer to something that isn't really a
partial_symtab, after which everything goes wrong.
Initially I simply added a check at the start of find_pc_sect_psymtab
that the objfile had some partial_symtabs, like:
if (objfile->partial_symtabs->psymtabs == NULL)
return NULL;
Figuring that if there were no partial_symtabs at all then this
function should always return NULL, however, this caused a failure in
the test gdb.python/py-event.exp which I didn't dig into too deeply,
but seems to be that in this tests there are initially no psymtabs,
but the second part of find_pc_sect_psymtab does manage to read some
in from somewhere, with the check I added the test fails as we
returned NULL here and this caused GDB to load in the full symtabs
earlier than was expected.
Instead I chose to guard only the access to psymtabs_addrmap with a
check that the function has some psymtabs. This allows my original
tests to pass, and the py-event.exp test to pass too.
Now, a good argument can be made that we simply should never call
find_pc_sect_psymtab on an objfile that is using indexes instead of
partial_symtabs. I did consider this approach, we could easily add an
assert into find_pc_sect_psymtab that if we find a partial_symtab in
psymtabs_addrmap then the psymtabs pointer must be non-null. The
responsibility would then be on the user of find_pc_sect_psymtab to
ensure that the objfile being checked is suitable. In the end I
didn't take this approach as the check in find_pc_sect_psymtab is

not cause problems.

holds more than just partial_symtabs as this was not at all clear from
the original comment, and caused me some confusion when I was
initially debugging this problem.

[gdb/testsuite] Allow some tests in gdb.base/store.exp to be unsupported
The test-case gdb.base/store.exp fails with gcc 7.4.0:
...
nr of unexpected failures 27
...
The first FAIL:
...
110 l = add_float (l, r);
(gdb) PASS: gdb.base/store.exp: continue to wack_float
print l
$21 = <optimized out>
FAIL: gdb.base/store.exp: var float l; print old l, expecting -1
...
relates to this bit in the test-case (compiled at -O0):
...
106 float
107 wack_float (register float u, register float v)
108 {
109 register float l = u, r = v;
110 l = add_float (l, r);
111 return l + r;
112 }
...
and it expects to be able to read and modify variable l before executing line
110, but it already fails to read the value, because l has no DW_AT_location
attribute in the debug info.
Variable l is declared with the register keyword, and GCC implements the
register keyword at -O0 like so:
...
the compiler allocates distinct stack memory for all variables that do not
have the register storage-class specifier; if register is specified, the
variable may have a shorter lifespan than the code would indicate and may
never be placed in memory.
...
The fact that l has no DW_AT_location attribute, matches with the documented
"variable may have a shorter lifespan that code would indicate", (though it
is the most extreme case of it) so the gcc behaviour is valid. We can of
course improve gcc to generate better debuginfo (filed gcc PR91611), but
this not a wrong-debug problem.
[ The test-case passes with gcc 4.2.1, but for the failing test discussed
above, it passes simply because it doesn't store l in a register. ]
With the debug info missing for l, reading and setting l is unsupported, so
fix the FAIL by marking the test UNSUPPORTED instead.
Tested on x86_64-linux.

Output the Ada task name in more messages.
With this patch, we e.g. get:
[Switching to task 2 "task_list(1)"]
[Current task is 2 "task_list(1)"]
instead of
[Switching to task 2]
[Current task is 2]
The logic to produce the taskno optionally followed
by the task name has been factorized in the task_to_str function.
Task names are output between double quotes in the new messages,
similarly to what GDB does for thread names.
However, no quotes are put around task names in 'info tasks' Name column.
This was discussed with Tom, that preferred no quotes there, while I
was more in favour of visual consistency.
I discussed with a few more users, which led to (exactly) 50% preferring
quotes and 50% preferring no quotes :).
To arrive to the decision to remove the quotes, the following "killing args"
were used:
* To have quotes or to not have quotes, that is the question; yes
but not *THE* question :).
* If there is not a clear majority that prefers quotes, better to
not disturb the existing user basis for a (somewhat) irrelevant
aspect.
* The opinion of the reviewer has more weight.
So, compared to the previous version, this version remotes the quotes
in 'info tasks'.
It improves the alignement of 'info tasks' output.
With this patch, we get:
(gdb) info task
ID TID P-ID Pri State Name
* 1
555555759030 48 Runnable main_task
2
555555759e30 1 48 Selective Wait mit
(gdb)
instead of
(gdb) info task
ID TID P-ID Pri State Name
* 1
555555759030 48 Runnable main_task
2
555555759e30 1 48 Selective Wait mit
(gdb)
(e.g. the first one properly shows parent and priority under the
correct header).
This is version 4 of the 'task name' patch.
Compared to version 3, the changes are:
output task names between quotes but not in 'info tasks'

PR24981, Hit assertion failure in ld/ldlang.c:7504
This fixes a problem with commit
128bf1fe608, a patch I made
2019-08-06. Apparently it is possible to trigger the assertion I
added during an LTO bootstrap, something I haven't reproduced.
However, I did find a case triggered by an odd linker script feature
that allows a file to be loaded from the script without specifying
that file on the command line. Regarding input sections:
"When you use a file name which is not an archive:file specifier
and does not contain any wild card characters, the linker will
first see if you also specified the file name on the linker command
line or in an INPUT command. If you did not, the linker will
attempt to open the file as an input file, as though it appeared on
the command line."
So putting
.foo : { foo.a(*) }
into a script supposedly extracts foo.a into .foo. Except it doesn't,
since this feature is meant for object files only. Well anyway,
assuming --whole-archive was given on the command line, foo.a contains
a -flto object and no other objects involved were -flto then we'll hit
the assert due to files added like foo.a here *not* having their input
statement put on the general statement list. Why these are not put on
the statement list isn't obvious but it has been that way since commit
193c5f93a17 in 1994.

Fix signals reported for faults on Solaris
It's been a long-standing nuisance that gdb reported unaligned accesses
on Solaris/SPARC as SIGSEGV, contrary to the shells and truss which
correctly report SIGBUS instead.
I could trace this down to the fault handling code in procfs.c
(procfs_target::wait): when pr_why is set to PR_FAULTED, the current
code sets the signal based on the fault number. For one, the code gets
this wrong for FLTACCESS (the unaligned access case) where it uses
SIGSEGV. What's worse, it's completely unnecessary to make up the
signal number inside gdb. Instead, it should just take what procfs
reports to avoid mismatches, which is what this patch does. I've
completely removed the explicit handling of the various fault codes: for
one, the list has already been incomplete, lacking FLTCPCOVF which
existed since at least Solaris 8. Besides, there's no reason to error
out on unknown fault codes: either the fault causes a signal which can
then be reported from procfs, or it doesn't (as for FLTPAGE) and no
reporting is necessary.
Tested on sparcv9-sun-solaris2.11 and x86_64-pc-solaris2.11. Also
spot-checked manually for a couple of cases (unaligned access, division
by 0, NULL pointer dereference).
* procfs.c (procfs_target::wait) <PR_FAULTED>: Get signal from

Move elf32.em and elf-generic.em functions
Many ELF linker targets support multiple "emulations" and thus have
multiple copies of elf32.em being compiled and linked into ld. This
patch moves much of elf32.em and elf-generic.em into files which will
be compiled just once, resulting in a 20% decrease in ld size for
--enable-targets=all.

Fix latent bug in .debug_names file-name handling
An internal Ada test case showed that the .debug_names code does not
compute the same list of file names as the partial symbol reader. In
particular, the partial symbol reader uses the DW_AT_name of the CU:
/* Allocate a new partial symbol table structure. */
filename = dwarf2_string_attr (comp_unit_die, DW_AT_name, cu);
if (filename == NULL)
filename = "";
pst = create_partial_symtab (per_cu, filename);
