For some reason install-dvi is missing although other targets of the
same family are present. This looks like an oversight.
This enables calling 'make install-dvi' from the top-level build
directory.
Fix what looks like another oversight: include 'pdf' in 'all-doc' in
gdb/doc/Makefile.in.

This patch rewrites gdb_bfd_error_handler to use 'bfd_print_error' to
generate the text of the warning, and then emits it using 'warning'.
The current code in the tree is a bit wrong because it may do the
wrong thing when BFD uses ones of its printf extensions.
This also adds locking to increment_bfd_error_count. This is
important now that some BFD operations can be done on worker threads.
This approach makes it simpler for worker threads to intercept any
messages.
Regression tested on x86-64 Fedora 38.

when processing the GDBserver reply to qRcmd packet.
Print error message or the error code.
Currently, when qRcmd request returns an error,
GDB just prints:
Protocol error with Rcmd
After this change, GDB will also print the error code:
Protocol error with Rcmd: 01.
Add an accept_msg argument to packet_check result. qRcmd
request (such as many other packets) does not recognise
"E.msg" form as an error right now. We want to recognise
"E.msg" as an error response only for the packets where
it's documented.
Also use packet_check result in remote_read_bytes_1.

Following the suggestion in this review comment:
https://inbox.sourceware.org/gdb-patches/9420bbb0-2614-4847-9157-8562f8a62d03@simark.ca
this commit realigns the AC_ARG_ENABLE(sim, ....) block. I've added
additional [...] quoting in a couple of places, which is inline with
how other AC_ARG_ENABLE blocks are formatted within GDB's configure.ac
file.
There should be no change in how GDB configures or builds after this
commit.

This commit makes use of gdb/silent-rules.mk in the data-directory
Makefile.in. I've only updated the rules that actually generate
things, I've not touched the install or uninstall rules, this matches
gdb/Makefile.in.
I've not managed to completely silence all of the recipe output, the
mkinstalldirs command outputs some diagnostic text which looks like
this:
GEN stamp-python
mkdir -p -- ./python/gdb
mkdir -p -- ./python/gdb/command
mkdir -p -- ./python/gdb/dap
mkdir -p -- ./python/gdb/function
mkdir -p -- ./python/gdb/printer
I have a patch for mkinstalldirs that fixes this (by adding a new
--silent command line flag), but that patch needs to be submitted to
automake, then an updated mkinstalldirs sync'd to the gcc repository,
and then copied into the binutils-gdb repository... so I'm leaving
that for a future project.
Then the guild compiler also emits some diagnostic output, which looks
like this:
GEN stamp-guile
mkdir -p -- ./guile/.
mkdir -p -- ./guile/gdb
wrote `./gdb.go'
wrote `gdb/experimental.go'
wrote `gdb/iterator.go'
wrote `gdb/printing.go'
wrote `gdb/support.go'
wrote `gdb/types.go'
The 'wrote' lines are from the guild compiler. The only way to
silence these would be to redirect stdout to /dev/null I think. I did
prototype this, but wasn't 100% convinced about that part of the
patch, so I've decided to leave that for another day.
I did need to add a new SILENT_ECHO variable to silent-rules.mk, this
is set to a suitable 'echo' command to use within recipes. When we
are in silent mode then I use the 'true' command, while in verbose
mode we actually use 'echo'.
So, other than the issues outlined above, the output when building the
data-directory is now greatly reduced, and more inline with the output
when building in the gdb/ directory.
There should be no change in what is actually built after this commit.

After the recent commits, I noticed that GDB's configure script would
still emit two lines even when run in silent mode. If you touch
gdb/Makefile.in and then run 'make all' in the gdb/ build directory
you'll see this:
GEN config.status
enable_sim = no
enableval = no
Obviously the 'no' might be 'yes' depending on how you actually
configured GDB.
This is caused by two direct invocations of 'echo' in GDB's
configure.ac script.
In this commit I replace these calls with use of AC_MSG_NOTICE
instead. Now when configure is run with the --silent command line
option these lines will not be printed.
There should be no changes in the built GDB after this commit.

The targets that use config.status to regenerate themselves don't
currently follow the silent rules that the rest of GDB's Makefile
does. For example, touch the gdb/gcore.in file and then 'make all' in
the gdb/ directory prints:
/bin/sh config.status gcore
config.status: creating gcore
In this commit I make use of the silent-rules.mk mechanism for these
targets, now we get:
GEN gcore
Which matches the rest of our Makefile. Obviously, if you pass 'V=1'
to the build then you'll get the old output back.

I noticed that for the build targets jit-reader.h, gcore, gdb-gdb.py,
and gdb-gdb.gdb the rules all use the config.status script, but don't
have a dependency on the config.status target. This means we might
fail to regenerate these targets in a case where config.status, or one
of its dependencies changes.
Two other targets that use config.status do correctly have a
dependency on config.status.
Fixed in this commit by adding the missing dependencies.

I noticed something weird, the rule for the config.status target looks
like this:
config.status: $(srcdir)/configure configure.nat configure.tgt configure.host ../bfd/development.sh
$(SHELL) config.status --recheck
What bothered me is that 'configure' is specified as being in
$(srcdir), while all of the other files are not, even though those
files are in the same $(srcdir) as the configure script.
However, I tried touching one of those files, and the config.status
rule does trigger!
This is thanks to the VPATH variable, which is set to $(srcdir), so
make looks in $(srcdir) for any dependencies.
However, this inconsistency bothers me. Better, I think, to add the
$(srcdir) prefix to each of these files.
I also spotted that the configure script also includes the files
../bfd/config.bfd, yet that is missing from the include list, so in
this commit I plan to add this as a dependency.
The configure script also pulls in two TCL and TK related files:
. ${TCL_BIN_DIR}/tclConfig.sh
. ${TK_BIN_DIR}/tkConfig.sh
However, I don't think ${TCL_BIN_DIR} and ${TK_BIN_DIR} are currently
visible in GDB's Makefile, so I'm not planning to add these
dependencies at this time.
In this commit I add a new variable config_status_deps which holds the
list of all the dependencies for config.status, with the $(srcdir)
prefix included, and then I use this in the config.status rule.
After this commit config.status will regenerate if config.bfd changes,
which it wouldn't before, but nothing else changes.

The gcore script is initially generated by the configure process, just
like gdb-gdb.gdb and gdb-gdb.py. However if the gdb/gcore.in input
source is modified then 'make all' in the gdb/ directory does not
regenerate the gcore script.
This is different than the gdb-gdb.gdb and gdb-gdb.py files, if their
input is updated then 'make all' will regenerate these files.
The difference is that for gdb-gdb.* there is an explicit dependency
between the 'all' target and the generated file, this dependency is
missing for gcore.
This commit adds the dependency. Now, if gcore.in is changed, running
'make all' will regenerate the gcore script.

In ada-lex.l, we already use `DIAGNOSTIC_IGNORE_DEPRECATED_REGISTER`,
which for Clang translates to ignoring `-Wdeprecated-register` [1]. I think
that was produced when compiling as C++11, but now that we always compile as
C++17, Clang produces a `-Wregister` error [2].
For GCC, `DIAGNOSTIC_IGNORE_DEPRECATED_REGISTER` already translates to
ignoring `-Wregister`. So, rename
`DIAGNOSTIC_IGNORE_DEPRECATED_REGISTER` to `DIAGNOSTIC_IGNORE_REGISTER`
and ignore `-Wregister` for Clang too.

In a previous review, I noticed that some code in gdb/compile/compile.c
could use c++17's `std::filesystem::remove_all` instead of using some
`system ("rm -rf ...");`.
This patch implements this.
Note that I use the noexcept overload of std::filesystem::remove_all and
explicitly check for an error code. This means that this code called
during the cleanup procedure cannot throw, and does not risk preventing
other cleanup functions to be called.

I recent change (e9b738dfbdc "Avoid race when reading dwz file") moved
the call to dwarf2_read_dwz_file from dwarf2_initialize_objfile to
dwarf2_has_info.
Before that patch, dwarf2_initialize_objfile was only called when
dwarf2_has_info returned true, and since that patch it is always called.
When reading a file that has no debug info (.debug_info/.debug_abbrev
sections), but has a .gnu_debugaltlink section, GDB’s behavior is
different. I can observe this when loading
/lib/x86_64-linux-gnu/libtinfo.so on Ubuntu 22.04 (or while debugging
any program dynamically loading this library).
Before e9b738dfbdc, we had:
$ ./gdb/gdb -data-directory ./gdb/data-directory -q /lib/x86_64-linux-gnu/libtinfo.so
Reading symbols from /lib/x86_64-linux-gnu/libtinfo.so...
(No debugging symbols found in /lib/x86_64-linux-gnu/libtinfo.so)
(gdb)
while after we have:
$ ./gdb/gdb -data-directory ./gdb/data-directory -q /lib/x86_64-linux-gnu/libtinfo.so
Reading symbols from /lib/x86_64-linux-gnu/libtinfo.so...
warning: could not find '.gnu_debugaltlink' file for /usr/lib/x86_64-linux-gnu/libtinfo.so.6.3
(No debugging symbols found in /lib/x86_64-linux-gnu/libtinfo.so)
(gdb)
This patch restores the previous behavior of only trying to load the
DWZ file for objfiles when the main part of the debuginfo is present
(i.e. when dwarf2_has_info returns true). We still make sure that
dwarf2_read_dwz_file is called at most once per objfile.
A consequence of this change is that the per_bfd->dwz_file optional
object can now remain empty (instead of containing a nullptr), so also
this patch also adjusts dwarf2_get_dwz_file to account for this
possibility. This effectively reverts the changes to
dwarf2_get_dwz_file done by e9b738dfbdc.
Regression tested on x86_64-linux-gnu Ubuntu 22.04.

Investigating GDB PR d/31580 showed that the libiberty demangler
doesn't automatically demangle D mangled names. However, I think it
should -- like C++ and Rust (new-style), D mangled names are readily
distinguished by the leading "_D", and so the likelihood of confusion
is low. The other non-"auto" cases in this code are Ada (where the
encoded form could more easily be confused by ordinary programs) and
Java (which is long gone, but which also shared the C++ mangling and
thus was just an output style preference).
This patch also fixed another GDB bug, though of course that part
won't apply to the GCC repository.

While examining the Ada parser globals with 'nm', I noticed that the
lexer's "attributes" array should be const. This change moves it into
read-only storage.
|
|
The lexer has a "numbuf" global that is only used for temporary
storage. This patch removes the global and redeclares it at the
points of use.
|

This moves the "returned_complete" global into ada_parse_state.
|
|
This moves the "paren_depth" global into ada_parse_state.
|

This patch moves the "temp_parse_space" global into ada_parse_state.

|
|
This patch moves the "int_storage" global into ada_parse_state.
|
|
This patch introduces the ada_parse_state class and the ada_parser
global. It also changes find_completion_bounds to be a method of this
new type.
Note that find_completion_bounds never used its parameter; and because
it is generally fine to use the 'pstate' global throughout the parser,
this patch removes the parameter entirely.

Ada 2022 includes iterated assignment for array initialization. This
patch implements a subset of this for gdb. In particular, only arrays
with integer index types really work -- currently there's no decent
way to get the index type in EVAL_AVOID_SIDE_EFFECTS mode during
parsing. Fixing this probably requires the Ada parser to take a
somewhat more sophisticated approach to type resolution; and while
this would help fix another bug in this area, this patch is already
useful without it.

This patch is a refactoring to add a new aggregate_assigner type.
This type is passed to Ada aggregate assignment operations in place of

I noticed in code_breakpoint::code_breakpoint that we are calling
update_dprintf_command_list once for each breakpoint location, when we
really only need to call this once per breakpoint -- the data updated
by this function, the breakpoint command list -- is per breakpoint,
not per breakpoint location. Calling update_dprintf_command_list
multiple times is just wasted effort, there's no per location error
checking, we don't even pass the current location to the function.
This commit moves the update_dprintf_command_list call outside of the
per-location loop.
There should be no user visible changes after this commit.

Given the changes in the previous couple of commits, this commit
cleans up some of the asserts and 'if' checks related to the
extra_string within a dprintf breakpoint.
This commit:
1. Adds some asserts to update_dprintf_command_list about the
breakpoint type, and that the extra_string is not nullptr,
2. Given that we know extra_string is not nullptr (this is enforced
when the breakpoint is created), we can simplify
code_breakpoint::code_breakpoint -- it no longer needs to check for
the extra_string is nullptr case,
3. In dprintf_breakpoint::re_set we can remove the assert (this will
be checked within update_dprintf_command_list, we can also remove
the redundant 'if' check.
There should be no user visible changes after this commit.
|

I noticed in update_dprintf_command_list that we handle the case where
the bp_dprintf style breakpoint doesn't have a format and args string.
However, I don't believe such a situation is possible. The obvious
approach certainly already catches this case:
(gdb) dprintf main
Format string required
If it is possible to create a dprintf breakpoint without a format and
args string then I think we should be catching this case and handling
it at creation time, rather than having GDB just ignore the situation
later on.
And so, I propose that we change the 'if' that ignores the case where
the format/args string is empty, and instead assert that we do always
have a format/args string. The original code, that handled an empty
format/args string has existed since commit e7e0cddfb0d4, which is
when dprintf support was added to GDB.
If I'm correct and this situation can't ever happen then there should
be no user visible changes after this commit.

The goal of this commit is to better define the API for
create_breakpoint especially around the use of extra_string and
parse_extra. This will be useful in the next commit when I plan to
make some changes to create_breakpoint.
This commit makes one possibly breaking change: until this commit it
was possible to create thread-specific dprintf breakpoint like this:

printf "%s", "hello"
(gdb)
This feature of dprintf was not documented, was not tested, and is
slightly different in syntax to how we create thread specific
breakpoints and/or watchpoints -- the thread condition appears after
the first ','.
I believe that this worked at all was simply by luck. We happen to
pass the parse_extra flag as true from dprintf_command to
create_breakpoint.
So in this commit I made the choice to change this. We now pass
parse_extra as false from dprintf_command to create_breakpoint. With
this done it is assumed that the only thing in the extra_string is the
dprintf format and arguments.
Beyond this change I've updated the comment on create_breakpoint in
breakpoint.h, and I've then added some asserts into
create_breakpoint as well as moving around some of the error
handling.
- We now assert on the incoming argument values,
- I've moved an error check to sit after the call to
find_condition_and_thread_for_sals, this ensures the extra_string
was parsed correctly,
In dprintf_command:
- We now throw an error if there is no format string after the
dprintf location. This error was already being thrown, but was
being caught later in the process. With this change we catch the
missing string earlier,
- And, as mentioned earlier, we pass parse_extra as false when
calling create_breakpoint,
In create_tracepoint_from_upload:
- We now throw an error if the parsed location doesn't completely
consume the addr_str variable. This error has now effectively
moved out of create_breakpoint.
