Consider the test-case contained in this patch.
With -readnow, we have two breakpoint locations:
...
$ gdb -readnow -batch breakpoint-locs -ex "b N1::C1::baz" -ex "info break"
Breakpoint 1 at 0x4004cb: N1::C1::baz. (2 locations)
Num Type Disp Enb Address What
1 breakpoint keep y <MULTIPLE>
1.1 y 0x00000000004004cb in N1::C1::baz() \
at breakpoint-locs.h:6
1.2 y 0x00000000004004f0 in N1::C1::baz() \
at breakpoint-locs.h:6
...
But without -readnow, we have instead only one breakpoint location:
...
$ gdb -batch breakpoint-locs -ex "b N1::C1::baz" -ex "info break"
Breakpoint 1 at 0x4004f0: file breakpoint-locs.h, line 6.
Num Type Disp Enb Address What
1 breakpoint keep y 0x00000000004004f0 in N1::C1::baz() \
at breakpoint-locs.h:6

The missing breakpoint location is specified by DIE 0x161, which is ignored by
the partial DIE reader because it's a child of a DW_TAG_subprogram DIE (at
0x146, for foo).
Fix this by not ignoring the DIE during partial DIE reading.
Tested on x86_64-linux.

Don't do anything special with non-loaded, non-alloced sections.
In particular, any relocs in such sections should not affect GOT
and PLT reference counting (ie. we don't allow them to create GOT
or PLT entries), there's no possibility or desire to optimize TLS
relocs, and there's not much point in propagating relocs to shared
libs that the dynamic linker won't relocate.

This is the consequence of the use of global verbose in these tests, which is
used to change the actual test, rather than be more verbose about it.
Fix this by defining a global test_verbose in each test, and using that
instead.

--export-dynamic-symbol-list is like a dynamic list, but without
the symbolic property for unspecified symbols.
When creating an executable, --export-dynamic-symbol-list is treated
like --dynamic-list.
When creating a shared library, it is treated like --dynamic-list if
-Bsymbolic or --dynamic-list are used, otherwise, it is ignored, so
that references to matched symbols will not be bound to the definitions
within the shared library.

https://sourceware.org/pipermail/binutils/2020-June/111383.html
Inlcude the bfd.h in the include/opcode/riscv.h may cause gdbserver fail
to build. I just want to use the `bfd_boolean` in the opcodes/riscv-opc.c,
but I didn't realize this cause the build failed. Fortunately, I can also
use the `int` as the function return types just like others in the
opcodes/riscv-opc.c.
include/
* opcode/riscv.h: Remove #include "bfd.h". And change the return
types of riscv_get_isa_spec_class and riscv_get_priv_spec_class
from bfd_boolean to int.
opcodes/
* riscv-opc.c (riscv_get_isa_spec_class): Change bfd_boolean to int.
(riscv_get_priv_spec_class): Likewise.

This commit changes the language_data::la_demangle function pointer
member variable into a member function of language_defn.
The only slightly "weird" change in this commit is in f-lang.c, where
I have given the Fortran language a demangle method that is identical
to the default language_defn::demangle. The only reason for this is
to give me somewhere to copy the comment that was previously embedded
within the f_language_data structure.

This commit changes the language_data::la_sniff_from_mangled_name
function pointer member variable into a member function of
language_defn.
Previously the la_sniff_from_mangled_name pointer was NULL for some
languages, however, all uses of this function pointer were through the
function language_sniff_from_mangled_name which provided a default
implementation.
This default implementation now becomes the implementation in the base
class language_defn, which is then overridden as required in various
language sub-classes.

This commit changes the language_data::la_pass_by_reference function
pointer member variable into a member function of language_defn.
The interesting thing in this commit is that I have removed the
default_pass_by_reference function entirely. This function only ever
returned a language_pass_by_ref_info struct in its default state, so
all uses of this function can be replaced by just default
initialisation of a language_pass_by_ref_info variable.

This commit changes the language_data::la_read_var_value function
pointer member variable into a member function of language_defn.
An interesting aspect of this change is that the implementation of
language_defn::read_var_value is actually in findvar.c. This is
partly historical, the new language_defn::read_var_value is a rename
of default_read_var_value, which was already in that file, but also,
that is the file that contains the helper functions needed by the
read_var_value method, so it makes sens that the method implementation
should continue to live there (I think).

This commit converts all languages to sub-classes of a language_defn
base class.
The motivation for this change is to make it easier to add new methods
onto languages without having to update all of the individual language
structures. In the future it might be possible to move more things,
like expression parsing, into the language class(es) for better
encapsulation, however I have no plans to tackle this in the short
term.
This commit sets up a strategy for transitioning from the current
language system, where each language is an instance of the
language_defn structure, to the class hierarchy system.
The plan is to rename the existing language_defn into language_data,
and make this a base class for the new language_defn class, something
like this:
struct language_data
{
... old language_defn fields here ...
};
struct language_defn : public language_data
{
language_defn (const language_data d)
: language_data (d)
{ .... }
};
Then each existing language, for example ada_language_defn can be
converted into an instance of language_data, and passed into the
constructor of a new language class, something like this:
language_data ada_language_data =
{
... old ada_language_defn values here ...
};
struct ada_language : public language_defn
{
ada_language (ada_language_data)
{ .... }
};
What this means is that immediately after the conversion nothing much
changes. Every language is now its own class, but all the old
language fields still exist and can be accessed in the same way.
In later commits I will convert function pointers from the old
language_defn structure into real class methods on language_defn, with
overrides on sub-classes where needed.
At this point I imagine that those fields of the old language_defn
structure that contained only data will probably remain as data fields
within the new language_data base structure, it is only the methods
that I plan to change initially.
I tweaked how we manage the list of languages a bit, each language is
now registered as it is created, and this resulted in a small number
of changes in language.c.
Most of the changes in the *-lang.c files are identical.
There should be no user visible changes after this commit.

Consider a gdb_load patch to call the gdb_file_cmd twice:
...
proc gdb_load { arg } {
if { $arg != "" } {
+ set res [gdb_file_cmd $arg]
+ if { $res != 0 } {
+ return $res
+ }
return [gdb_file_cmd $arg]
}
return 0
}
...
With this patch, I run into:
...
(gdb) kill^M
The program is not being run.^M
(gdb) ^M</outputs/gdb.dwarf2/multidictionary/multidictionary^M
<.dwarf2/multidictionary/multidictionary"? (y or n)

(gdb) UNRESOLVED: gdb.dwarf2/multidictionary.exp: GDB is alive \

...
The problem is that the second file command results in a prompt, which is
normally handled by gdb_file_cmd, but not recognized because the initial part
of the prompt is scrolled out.
This in turn is caused by using gdb_spawn_with_cmdline_opts without a
subsequent "set width 0".
Fix this by avoiding gdb_spawn_with_cmdline_opts, and forcing -readline by
temporarily modifying GDBFLAGS instead.
Tested on x86_64-linux.

There are a number of targets that don't support thin archives (*),
and vms doesn't even support file name extensions other than .obj for
archives containing object files. This patch adjusts the testsuite
to cater for the vms restriction, and reenables testing for non-ELF
alpha targets. That adds a few alpha-dec-vms fails and one
alpha-linuxecoff fail but testsuite fails on those targets are nothing
new.
(*) It might seem like they do if binutils is built with
--enable-plugins but the plugin archive support is broken, causing the
wrong type of archives to be created by ar for those targets.
* testsuite/binutils-all/ar.exp (obj): Set up object file name
extension. Use throughout. Don't completely exclude non-ELF
alpha targets. Run long_filenames test for tic30. Exclude thin
archive tests for aix, ecoff and vms.
* estsuite/binutils-all/objdump.exp (obj): Set up object file name
extension. Use throughout. Don't exclude non-ELF alpha targets
from "bintest.a".

After the is-stmt support commit:
commit 8c95582da858ac981f689a6f599acacb8c5c490f
Date: Mon Dec 30 21:04:51 2019 +0000
gdb: Add support for tracking the DWARF line table is-stmt field
A regression was observed where a breakpoint could no longer be placed
in some cases.
Consider a line table like this:
File 1: test.c
File 2: test.h
| Addr | File | Line | Stmt |
|------|------|------|------|
| 1 | 1 | 16 | Y |
| 2 | 1 | 17 | Y |
| 3 | 2 | 21 | Y |
| 4 | 2 | 22 | Y |
| 4 | 1 | 18 | N |
| 5 | 2 | 23 | N |
| 6 | 1 | 24 | Y |
| 7 | 1 | END | Y |
|------|------|------|------|
Before the is-stmt patch GDB would ignore any non-stmt lines, so GDB
built two line table structures:
File 1 File 2
------ ------
| Addr | Line | | Addr | Line |
|------|------| |------|------|
| 1 | 16 | | 3 | 21 |
| 2 | 17 | | 4 | 22 |
| 3 | END | | 6 | END |
| 6 | 24 | |------|------|
| 7 | END |
|------|------|
After the is-stmt patch GDB now records non-stmt lines, so the
generated line table structures look like this:
File 1 File 2
------ ------
| Addr | Line | Stmt | | Addr | Line | Stmt |
|------|------|------| |------|------|------|
| 1 | 16 | Y | | 3 | 21 | Y |
| 2 | 17 | Y | | 4 | 22 | Y |
| 3 | END | Y | | 4 | END | Y |
| 4 | 18 | N | | 5 | 23 | N |
| 5 | END | Y | | 6 | END | Y |
| 6 | 24 | Y | |------|------|------|
| 7 | END | Y |
|------|------|------|
The problem is that in 'File 2', end END marker at address 4 causes
the previous line table entry to be discarded, so we actually end up
with this:
File 2
------
| Addr | Line | Stmt |
|------|------|------|
| 3 | 21 | Y |
| 4 | END | Y |
| 5 | 23 | N |
| 6 | END | Y |
|------|------|------|
When a user tries to place a breakpoint in file 2 at line 22, this is
no longer possible.
The solution I propose here is that we ignore line table entries that
would trigger a change of file if:
1. The new line being added is at the same address as the previous
line, and
2. We have previously seen an is-stmt line at the current address.
The result of this is that GDB switches file, and knows that some line
entry (or entries) are going to be discarded, prefer to keep is-stmt
lines and discard non-stmt lines.
After this commit the lines tables are now:
File 1 File 2
------ ------
| Addr | Line | Stmt | | Addr | Line | Stmt |
|------|------|------| |------|------|------|
| 1 | 16 | Y | | 3 | 21 | Y |
| 2 | 17 | Y | | 4 | 22 | Y |
| 3 | END | Y | | 5 | 23 | N |
| 5 | END | Y | | 6 | END | Y |
| 6 | 24 | Y | |------|------|------|
| 7 | END | Y |
|------|------|------|
We've lost the non-stmt entry for file 1, line 18, but retained the
is-stmt entry for file 2, line 22. The user can now place a
breakpoint at that location.
One problem that came from this commit was the test
gdb.cp/step-and-next-inline.exp, which broke in several places. After
looking at this test again I think that in some cases this test was
only ever passing by pure luck. The debug GCC is producing for this
test is pretty broken. I raised this GCC bug:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=94474
for this and disabled one entire half of the test. There are still
some cases in here that do pass, and if/when GCC is fixed it would be
great to enable this test again.

member variable.
<m_stmt_at_address>: New member variable.

We are using -Werror=missing-declarations, and the _S.h files generated
by mig do not currently include a declaration for the server routine.
gnu-nat.c used to have its own external declarations, but better just
share them between gnu-nat.c and the _S.c files.
Fixes
