A recent version of GCC changed how fixed-point types are described.
For example, a denominator in one test case now looks like:
GNU_denominator (exprloc)
[ 0] implicit_value: 16 byte block: 00 00 b8 9d 0d 69 55 a0 01 00 00 00 00 00 00 00
... the difference being that this now uses exprloc and emits a
DW_OP_implicit_value for the 16-byte block. (DWARF 5 still uses
DW_FORM_data16.)
This change was made here:
https://gcc.gnu.org/pipermail/gcc-patches/2020-December/560897.html
This patch updates gdb to handle this situation.
Note that, before GCC 11, this test would not give the same answer.
Earlier versions of GCC fell back to GNAT encodings for this case.

A user noticed that the Ada expression code in gdb did not
automatically disambiguate an enumerator in an array context. That
is, an expression like "print array(enumerator)" is not ambiguous,
even if "enumerator" is declared in multiple enumerations, because the
correct one can be found by examining the array's index type.

case.

This is inside a TYPE_ALLOC macro. The fact that gdbarch_obstack is
called means that the type is flagged as being arch-owned, but arch=0x0
means that type::arch returned NULL, probably meaning that the m_owner
field contains NULL.
If we look at the code before the problematic patch, in the
copy_type_recursive function, we see:
if (! TYPE_OBJFILE_OWNED (type))
return type;
...
TYPE_OBJFILE_OWNED (new_type) = 0;
TYPE_OWNER (new_type).gdbarch = get_type_arch (type);
The last two lines were replaced with:
new_type->set_owner (type->arch ());
get_type_arch and type->arch isn't the same thing: get_type_arch gets
the type's arch owner if it is arch-owned, and gets the objfile's arch
if the type is objfile owned. So it always returns non-NULL.
type->arch returns the type's arch if the type is arch-owned, else NULL.
So since the original type is objfile owned, it effectively made the new
type arch-owned (that is good) but set the owner to NULL (that is bad).
Fix this by using get_type_arch again there.
I spotted one other similar change in lookup_array_range_type, in the
original patch. But that one appears to be correct, as it is executed
only if the type is arch-owned.
Add some asserts in type::set_owner to ensure we never set a NULL owner.
That would have helped catch the issue a little bit earlier, so it could
help in the future.

* gdbtypes.c (copy_type_recursive): Use get_type_arch.
* gdbtypes.h (struct type) <set_owner>: Add asserts.

Before this patch, gdb_tilde_expand would use glob(3) in order to expand
tilde at the begining of a path. This implementation has limitation when
expanding a tilde leading path to a non existing file since glob fails to
expand.
This patch proposes to use glob only to expand the tilde component of the
path and leaves the rest of the path unchanged.
This patch is a followup to the following discution:

gdb_tilde_expand("~") -> "/home/lsix"

This commit adds a new 'version' style, which replaces the hard coded
styling currently used for GDB's version string. GDB's version number
is displayed:
1. In the output of 'show version', and
2. When GDB starts up (without the --quiet option).
This new style can only ever affect the first of these two cases as
the second case is printed before GDB has processed any initialization
files, or processed any GDB commands passed on the command line.
However, because the first case exists I think this commit makes
sense, it means the style is no longer hard coded into GDB, and we can
add some tests that the style can be enabled/disabled correctly.
This commit is an alternative to a patch Tom posted here:
https://sourceware.org/pipermail/gdb-patches/2020-June/169820.html
I've used the style name 'version' instead of 'startup' to reflect
what the style is actually used for. If other parts of the startup
text end up being highlighted I imagine they would get their own
styles based on what is being highlighted. I feel this is more inline
with the other style names that are already in use within GDB.
I also decoupled adding this style from the idea of startup options,
and the possibility of auto-saving startup options. Those ideas can
be explored in later patches.
This commit should probably be considered only a partial solution to
issue PR cli/25956. The colours of the style are no longer hard
coded, however, it is still impossible to change the styling of the
version string displayed during startup, so in one sense, the styling
of that string is still "hard coded". A later patch will hopefully
extend GDB to allow it to adjust the version styling before the
initial version string is printed.

While working on another patch I noticed that if I disable a single
style with, for example:
set style filename background none
set style filename foreground none
set style filename intensity normal
Then in some places escape characters are still injected into the
output stream. This is a bit of an edge case, and I can't think when
this would actually cause problems, but it still felt like a bit of an
annoyance.
One place where this does impact is in testing, where it becomes
harder to write tight test patterns if it is not obvious when GDB will
decide to inject escape sequences.
It's especially annoying because depending on how something is printed
then GDB might, or might not, add escape characters. So this would
not add escape characters if the filename style was disabled:
fprintf_filtered (file, "%ps",
styled_string (file_name_style.style (),
"This is a test"));
But this would add escape characters:
fprintf_styled (file, file_name_style.style (),
"%s", "This is a test");
I tracked this down to some calls to set_output_style in utils.c.
Currently some calls to set_output_style (in utils.c) are guarded like
this:
if (!STYLE.is_default ())
set_output_style (stream, STYLE);
But some calls are not. It is the calls that are NOT guarded that
cause the extra escape sequences to be emitted.
My initial proposal to resolve this issue was simply to ensure that
all calls to set_output_style were guarded. The patch I posted for
this can be found here:
https://sourceware.org/pipermail/gdb-patches/2021-January/175096.html
The feedback on this proposal was that it might be better to guard
against the escape sequences being emitted at a later lever, right
down at emit_style_escape.
So this is what this version does. In emit_style_escape we already
track the currently applied style, so if the style we are being asked
to switch to is the same as the currently applied style then no escape
sequence needs to be emitted.
Making this change immediately exposed some issues in
fputs_maybe_filtered related to line wrapping. The best place to start
to understand what's going on with the styling and wrapping is look at
the test:
gdb.base/style.exp: all styles enabled: frame when width=20
If you run this test and then examine the output in an editor so the
escape sequences can be seen you'll see the duplicate escape sequences
that are emitted before this patch, the compare to after this patch
you'll see the set of escape sequences should be the minimum required.
In order to test these changes I have rewritten the gdb.base/style.exp
test script. The core of the script is now run multiple times. The
first time the test is run things are as they were before, all styles
are on.
After that the test is rerun multiple times. Each time through a
single style is disabled using the 3 explicit set calls listed above.
I then repeat all the tests, however, I arrange so that the patterns
for the disabled style now require no escape sequences.

The node 'Auto-loading extensions' currently relies on a @menu item to
provide a set of cross-references to different parts of the manual.
Additionally the menu is placed part way through the node and the text
prior to the menu seems (to me) to assume that the menu will be
formatted into the document.
This is a bad idea as the menus are not always part of the final
document (e.g. pdf output does not include the menu), when compared to
the info page the pdf version of this node is less helpful as it lacks
proper cross references. Menus should always be placed at the end of
a node.
In this commit I rewrite a paragraph to add extra cross references
inline within the text. I then move the menu to the end of the node.

This is the next in the new-style debug macro series.
For this one, I decided to omit the function name from the "Sending packet" /
"Packet received" kind of prints, just because it's not very useful in that
context and hinders readability more than anything else. This is completely
arbitrary.
This is with:
[remote] putpkt_binary: Sending packet: $qTStatus#49...
[remote] getpkt_or_notif_sane_1: Packet received: T0;tnotrun:0;tframes:0;tcreated:0;tfree:500000;tsize:500000;circular:0;disconn:0;starttime:0;stoptime:0;username:;notes::
and without:
[remote] Sending packet: $qTStatus#49...
[remote] Packet received: T0;tnotrun:0;tframes:0;tcreated:0;tfree:500000;tsize:500000;circular:0;disconn:0;starttime:0;stoptime:0;username:;notes::
A difference is that previously, the query packet and its reply would be
printed on the same line, like this:
Sending packet: $qTStatus#49...Packet received: T0;tnotrun:0;tframes:0;tcreated:0;tfree:500000;tsize:500000;circular:0;disconn:0;starttime:0;stoptime:0;username:;notes::
Now, they are printed on two lines, since each remote_debug_printf{,_nofunc}
prints its own complete message including an end of line. It's probably
a matter of taste, but I prefer the two-line version, it's easier to
follow, especially when the query packet is long.
As a result, lib/range-stepping-support.exp needs to be updated, as it
currently expects the vCont packet and the reply to be on the same line.
I think it's sufficient in that context to just expect the vCont packet
and not the reply, since the goal is just to count how many vCont;r GDB
sends.

* common-debug.c (debug_prefixed_vprintf): Handle a nullptr
func.

As far as I can see, there are no more spots looking for a remote_debug
other than true/false. If we ever want to revert to an int, we can
always change it back later, but this makes things simpler for now.
gdb/ChangeLog:
* remote.h (remote_debug): Change to bool.
* remote.c (remote_debug): Change to bool.
(_initialize_remote): Adjust.
Change-Id: I21aac5b4cff9dc4f75c8efaf47c23583ecabd2a6
remote_debug is currently declared in target.h and defined in top.c.
Move them to remote.h and remote.c.
Include remote.h in remote-sim.c, as it uses remote_debug.
gdb/ChangeLog:
* target.h (remote_debug): Move to...
* remote.h (remote_debug): ... here.
* top.c (remote_debug): Move to...
* remote.c (remote_debug): ... here.
* remote-sim.c: Include remote.h.

Commands "set debug remote" and "set remotetimeout" are defined in
cli/cli-cmds.c, I think it would make more sense for them to be in
remote.c.
gdb/ChangeLog:
* cli/cli-cmds.c (show_remote_debug): Remove.
(show_remote_timeout): Remove.
(_initialize_cli_cmds): Don't register commands.
* remote.c (show_remote_debug): Move here.
(show_remote_timeout): Move here.
(_initialize_remote): Register commands.

type::objfile method instead.

Update all users to use the type::is_objfile_owned method.
gdb/ChangeLog:
* gdbtypes.h (TYPE_OBJFILE_OWNED): Remove, update all users to
use the type::is_objfile_owned method.
Change-Id: Icae84d136393ab9f756f50a33ac3cedda13c5ba2
Add the following methods to struct type:
* is_objfile_owned
* set_owner (objfile and gdbarch overloads)
* objfile and arch getters
Rename the fields in main_type to ensure no other code accesses them
directly. As usual, we can't make them actually private, but giving
them the `m_` prefix will help making sure they are not accessed when
not supposed to, by convention.
Remove the TYPE_OWNER macro to ensure no code uses the type_owner struct
directly.
gdb/ChangeLog:
* gdbtypes.h (TYPE_OBJFILE_OWNED): Adjust.
(TYPE_OWNER): Remove.
(TYPE_OBJFILE): Adjust.
(struct main_type) <flag_objfile_owned>: Rename to...
<m_flag_objfile_owned>: ... this.
<owner>: Rename to...
<m_owner>: ... this.
(struct type) <is_objfile_owned, set_owner, objfile, arch>: New
methods.
(TYPE_ALLOC): Adjust.
* gdbtypes.c (alloc_type): Adjust.
(alloc_type_arch): Adjust.

gdb/doc: reorder and group sections relating to aliases
Added a @menu block into the wrong place within a @node. This commit
moves it to the end of the @node, where it should be been placed.
gdb/doc/ChangeLog:
* gdb.texinfo (Aliases): Move @menu to the end of the node.
After a discussion on a recent patch it was pointed out that the
contents of a @var should (generally) be lower case. I took a look
through the GDB manual and there are a small number of places where
the contents are currently upper case, but one in particular seemed
like an obvious candidate for being down cased, so lets do that.
gdb/doc/ChangeLog:
* gdb.texinfo (PowerPC Embedded): Down case contents of @var.
On Ubuntu 18.04/20.04 I was running into annoying timeouts for
gdb.server/server-connect.exp. Those were caused by the ipv6 tests, because
they were running into the "Cannot assign requested address" error, originated
from the connect syscall.
Improve this by handling this additional error in the testsuite library.
It still fails for me, but at least it fails pretty quickly and doesn't make the
testsuite run take longer.

* lib/gdbserver-support.exp (gdb_target_cmd_ext): Handle a new error
message.
When building for 32-bit ARM, I ran into a couple build failures.
The first one seems to be caused by recent changes to warning switches,
leading to the following error:
--

gdb/coffread.c: In function "void enter_linenos(file_ptr, int, int, objfile*)":

^

complaint (_("Line number pointer %ld lower than start of line numbers"),

--
The other one is due to a narrowing conversion in valops.c:
--

Ubuntu 18.04/20.04.
gdb/ChangeLog:

* coffread.c (enter_linenos): Passing string to complaint.

Function file_is_auto_load_safe was taking a format string and varargs
just to output a debug print. This is probably because that function is
used in linux-thread-db.c and main.c, but debug_auto_load is static in
auto-load.c. I simplified that, making debug_auto_load visible outside
of auto-load.c, and making the callers of file_is_auto_load_safe output
the debug print themselves.
This file uses _() for internationalization of the debug messages. This
is not necessary, as these are mostly messages for GDB developers, and
it's not used in other files anyway. So I removed them.
The rest is pretty much standard.
gdb/ChangeLog:
* auto-load.h (debug_auto_load): Move here.
(auto_load_debug_printf): New.
* auto-load.c: Use auto_load_debug_printf.
(debug_auto_load): Move to header.
* linux-thread-db.c (try_thread_db_load): Use
auto_load_debug_printf.
* main.c (captured_main_1): Likewise.

This variable appears to be unused. Its uses were removed in commit
3e2e34f862 ("fort_dyn_array: Use value constructor instead of
raw-buffer manipulation.") back in 2016.

When GDB is waiting trying to connect to a remote target and it receives
a SIGWINCH (terminal gets resized), the blocking system call gets
interrupted and we abort.
For example, I connect to some port (on which nothing listens):
(gdb) tar rem :1234
... GDB blocks here, resize the terminal ...
🔢 Interrupted system call.
The backtrace where GDB is blocked while waiting for the connection to
establish is:

Fix that by using interruptible_select in wait_for_connect, instead of
gdb_select. Resizing the terminal now no longer aborts the connection.
It is still possible to interrupt the connection using ctrl-c.
gdb/ChangeLog:
* ser-tcp.c (wait_for_connect): Use interruptible_select instead
of gdb_select.

Here's a bonus patch that applies on top of the other two.
While debugging TUI test cases, it's hard to know what exactly is
happening in the little mind of the terminal emulator. Add some logging
for all input processing. Right now I'm interested in seeing what
happens to the cursor position, so made it so all operations log the
"before" and "after" cursor position. It should help see if any
operation is not behaving as expected, w.r.t. the cursor position.
Here are some examples of the logging found in gdb.log with this patch
applied:
+++ Inserting string '+|'
+++ Inserted char '+', cursor: (0, 79) -> (1, 0)
+++ Inserted char '|', cursor: (1, 0) -> (1, 1)
+++ Inserted string '+|', cursor: (0, 79) -> (1, 1)
+++ Cursor Horizontal Absolute (80), cursor: (1, 1) -> (1, 79)
In the last line, note that the argument is 80 and we move to 79, that's
because the position in the argument to the control sequence is 1-based,
while our indexing is 0-based.
gdb/testsuite/ChangeLog:
* lib/tuiterm.exp (_log, _log_cur): New, use throughout.
