gdb/fortran: add parser support for lbound and ubound
When I created the test gdb/testsuite/gdb.fortran/lbound-ubound.exp, I
copied the script from a different file and failed to delete the test
description comment at the top (even though I added a new
description). Fixed in this commit.
gdb/testsuite/ChangeLog:
* gdb.fortran/lbound-ubound.exp: Remove old comment.

The 'maintenance info sections' command currently takes a list of
filters on the command line. It can also accept the magic string
'ALLOBJ' which acts more like a command line flag, telling the command
to print information about all objfiles.
The manual has this to say about the options and filters:
... In addition, 'maint info sections' provides the following
command options (which may be arbitrarily combined): ...
Implying (to me at least) that I can do this:
(gdb) maint info sections ALLOBJ READONLY
to list all the read-only sections from all currently loaded object
files.
Unfortunately, this doesn't work. The READONLY filter will work, but
ALLOBJ will not be detected correctly.
It would be fairly simple to fix the ALLOBJ detection. However, I
dislike this mixing of command options (ALLOBJ) with command data (the
filters, e.g. READONLY, etc).
As this is a maintenance command, so not really intended for end
users, I think we can be a little more aggressive in "fixing" the
option parsing. So that's what I do in this commit.
The ALLOBJ mechanism is replaced with a real command
option (-all-objects). The rest of the command operates just as
before. The example above would now become:
(gdb) maint info sections -all-objects READONLY
The manual has been updated, and I added a NEWS entry to document the
change.

The 'maint info sections' command is split into two blocks or work,
first if there's an executable then the sections from the executable,
and optionally all other loaded object files are printed. Then all
the sections from any core file are printed.
I ran into a situation where (for various reasons) I wasn't using a
main executable. Instead I connected to a remote target and used
add-symbol-file. This allowed me to debug an image that was already
loaded on the remote system.
Unfortunately, when I tried to use 'maint info sections' I saw
nothing. The reason is that the loop over all object files is hidden
behind a check that we have a main executable.
This commit removes this check and merges together some duplicate
code. I also (I think) made the output of this command cleaner.
Here is the original output of 'maint info sections':
Exec file:
`/tmp/hello.x', file type elf64-x86-64.
[0] 0x004002a8->0x004002c4 at 0x000002a8: .interp ALLOC LOAD READONLY DATA HAS_CONTENTS
[1] 0x004002c4->0x004002e8 at 0x000002c4: .note.gnu.build-id ALLOC LOAD READONLY DATA HAS_CONTENTS
...
And my modified output:
Exec file: `/home/andrew/tmp/hello.x', file type elf64-x86-64.
[0] 0x004002a8->0x004002c4 at 0x000002a8: .interp ALLOC LOAD READONLY DATA HAS_CONTENTS
[1] 0x004002c4->0x004002e8 at 0x000002c4: .note.gnu.build-id ALLOC LOAD READONLY DATA HAS_CONTENTS
...
The forced newline after 'Exec file: ' has been removed. This is now
a wrap point (in case the filename is very long).
Here is the original output of 'maint info sections ALLOBJ':
Exec file:
`/tmp/hello.x', file type elf64-x86-64.
Object file: /tmp/hello.x

And my modified output:

...
The executable now only gets a single header line. The header line
for the additional object files is no longer indented as it was
before, and the line is laid out in a similar style to the main
executable line (with quotes and file type information).
And of course, the biggest change. If GDB is started with no
executable, but then the user does 'add-symbol-file ....' followed by
'maint info sections ALLOBJ', previously they got nothing, now they
get:
Object file: `/tmp/hello.x', file type elf64-x86-64.

The next couple of patches are going to add more tests for the 'maint
info sections' command. Rather than try to jam these tests into the
already quite long gdb.base/maint.c, this commit moves all of the
tests for 'maint info sections' into a new file.
I've updated the tests to make use of some newer testsuite constructs,
like -wrap and $gdb_test_name for gdb_test_multiple, but otherwise the
tests should not have changed with this commit.

The multi-target tests involve some inferiors using remote targets. By
default, GDB uses target: as the sysroot, which makes it read loaded
libraries and their debug info through GDBserver. This makes the tests
run slower than necessary.
Pass `-ex "set sysroot"` when launching GDB in these tests, so that GDB
always reads from its local file system.
On a system where I don't have debug info for libc, that reduces run
time for
$ make check TESTS="gdb.multi/multi-target-*.exp"
from 1:15 to 0:45.
On this other system where debug info is installed though, it reduces it
from 13:00 to 1:45.

Add support for the LBOUND and UBOUND built in functions to the
Fortran expression parser.
Both support taking one or two arguments. A single argument, which
must be an array, returns an array containing all of the lower or
upper bound data.
When passed two arguments, the second argument is the dimension being
asked about. In this case the result is a scalar containing the lower
or upper bound just for that dimension.
Some examples of usage taken from the new test:
# Given:
# integer, dimension (-8:-1,-10:-2) :: neg_array
#
(gdb) p lbound (neg_array)
$1 = (-8, -10)
(gdb) p lbound (neg_array, 1)

Right now, these libraries hardwire -L../intl -lintl on a few fixed
platforms, which works fine on those platforms but on other platforms
leads to shared libraries that lack libintl_* symbols when configured
--with-included-gettext, and/or static libraries that contain libintl as
*another* static library. If we instead use the LIBINTL variable
defined in ../intl/config.intl, this gives us the right thing on all
three classes of platform (gettext in libc, gettext in system libintl,
gettext in ../intl/libintl.a).. This also means we can rip out some
Darwin-specific machinery from configure.ac and also simplify the Cygwin
side.
This also means that the libctf testsuite (and other places that include
libbfd, libopcodes or libctf) don't need to grow libintl dependencies
just on account of those libraries (though they still need such
dependencies if they themselves use gettext machinery).

As Iain reported, my change broke the case when one has bison >= 3,
but make decides there is no reason to regenerate plural.c, unfortunately
that seems to be a scenario I haven't tested. The problem is that
the pregenerated plural.c has been generated with bison 1.35, but when
config.h says HAVE_BISON3, the code assumes it is the bison3 variant.
What used to work fine is when one has bison >= 3 and plural.c has been
regenerated (e.g. do touch intl/plural.y and it will work), or when
one doesn't have any bison (then nothing is regenerated, but HAVE_BISON3
isn't defined either), or when one has bison < 3 and doesn't need to
regenerate, or when one has bison < 3 and it is regenerated.
The following patch fixes this, by killing the HAVE_BISON3 macro from
config.h, and instead remembering the fact whether plural.c has been created
with bison < 3 or bison >= 3 in a separate new plural-config.h header.
The way this works:
- user doesn't have bison
- user has bison >= 3, but intl/{plural-config.h,plural.c} aren't older than intl/plural.y
- user has bison < 3, but intl/{plural-config.h,plural.c} aren't older than intl/plural.y
pregenerated !USE_BISON3 plural.c and plural-config.h from source
dir is used, nothing in the objdir
- user has bison >= 3 and intl/plural.y is newer
Makefile generates plural.c and USE_BISON3 plural-config.h in the
objdir, which is then used in preference to srcdir copies
- user has bison < 3 and intl/plural.y is newer
Makefile generates plural.c and !USE_BISON3 plural-config.h in the
objdir, which is then used in preference to srcdir copies
I have tested all these cases and make all-yes worked in all the cases.
If one uses the unsupported ./configure where srcdir == objdir, I guess
(though haven't tested) that it should still work, just it would be nice
if such people didn't try to check in the plural{.c,-config.h} they have
regenerated.
What doesn't work, but didn't work before either (just tested gcc-9 branch
too) is when one doesn't have bison and plural.y is newer than plural.c.
Don't do that ;)

bison 3 apparently made a backwards incompatible change, dropped
YYLEX_PARAM/YYPARSE_PARAM support and instead needs %param or %lex-param
and %parse-param. Furthermore, there is no easy way to conditionalize
on bison version in the *.y files.
While e.g. glibc bumped bison requirement and just has the bison 3
compatible version, Richi said there are still systems with older bison
where we want to build gcc.
So, this patch instead determines during configure bison version, and
depending on that when building plural.c (if building it at all) tweaks
what is passed over to bison if needed.
Tested with both bison 3 and bison 1.35, in each case with reconfiguring
intl and building with make all-yes (as in my setup intl isn't normally
used).

The problem originates in read_array_type, when reading a DW_TAG_array_type
with a dwarf-5 DW_TAG_generic_subrange child. This is not supported, and the
fallout of this is that rather than constructing a new array type, the code
proceeds to modify the element type.
Fix this conservatively by issuing a complaint and bailing out in
read_array_type when not being able to construct an array type, such that we
have:

This reverts commit 82a1fd3a4935fe665cf08bc6820942c4a091184c.
It was pointed out:
https://sourceware.org/pipermail/gdb-patches/2021-February/175750.html
that commit 82a1fd3a4935 caused GDB to have an unconditional
dependency on ELF specific parts of BFD. What this means is that if
GDB and BFD are built for a non-elf target then there will be
undefined symbol references within GDB.
The right solution isn't immediately obvious. So rather than rush a
fix in I'm reverting this commit for now, and will bring it back once
I have a good solution.

With a certain Ada program, ada-lang.c:coerce_unspec_val_to_type can
cause a crash. This function may copy a value, and in the particular
case in the crash, the new value's type is smaller than the original
type. This causes coerce_unspec_val_to_type to create a lazy value --
but the original value is also not_lval, so later, when the value is
un-lazied, gdb asserts.
As with the previous patch, we believe there is a compiler bug here,
but it is difficult to reproduce, so we're not completely certain.
In the particular case we saw, the original value has record type, and
the record holds some variable-length arrays. This leads to the
type's length being 0. At the same time, the value is optimized out.
This patch changes coerce_unspec_val_to_type to handle an
optimized-out value correctly.
It also slightly restructures this code to avoid a crash should a
not_lval value wind up here. This is a purely defensive change.
This change also made it clear that value_contents_copy_raw can now be
made static, so that is also done.

resolve_dynamic_struct says:

However, a certain Ada program has a structure with no fields but with

The tic54x exports some fairly generic variable names that can
conflict with programs that use them, so put proper tic54x_
prefixes on all of them.

The test expects the ifunc resolver to run lazily, at a later stage.
Depending on the distro and toolchain configuration, this is not the
case. Some configurations use non-lazy binding and thus the ifunc resolver
resolves all the ifunc references very early in the process startup, before
main.
Ubuntu is one such case. It has switched its toolchains to pass -Wl,z,now by
default, since 16.04. This wasn't a problem before 20.04 (at least for
aarch64) because the toolchains did not support ifunc's.
Forcing lazy binding makes the test run as expected, as opposed to the 80 or
so failures it showed before the change.
Tested on aarch64-linux/x86_64-linux Ubuntu 20.04.

When stepping over thread-lock related codes (in uClibc), the inferior process
gets stuck and never manages to enter the critical section:
------8<-------
1 size_t fwrite(const void * __restrict ptr, size_t size,
2 size_t nmemb, register FILE * __restrict stream)
3 {
4 size_t retval;
5 __STDIO_AUTO_THREADLOCK_VAR;
6
7 > __STDIO_AUTO_THREADLOCK(stream);
8
9 retval = fwrite_unlocked(ptr, size, nmemb, stream);
10
11 __STDIO_AUTO_THREADUNLOCK(stream);
12
13 return retval;
14 }
------>8-------
Here, we are at line 7. Using the "next" command leads no where.
However, setting a breakpoint on line 9 and issuing "continue" works.
Looking at the assembly instructions reveals that we're dealing with the
critical section entry code [1] that should never be interrupted, in this
case by the debugger's implicit breakpoints:
------8<-------
...
1 add_s r0,r13,0x38
2 mov_s r3,1
3 llock r2,[r0] <-.
4 brne.nt r2,0,14 --. |
5 scond r3,[r0] | |
6 bne -10 --|--'
7 brne_s r2,0,84 <-'
...
------>8-------
Lines 3 until 5 (inclusive) are supposed to be executed atomically.
Therefore, GDB should never (implicitly) insert a breakpoint on lines
4 and 5, else the program will try to acquire the lock again by jumping
back to line 3 and gets stuck in an infinite loop.
The solution is to make GDB aware of these patterns so it inserts
breakpoints after the sequence -- line 6 in this example.

"llock" (Load Locked) loads the 32-bit word pointed by the source
operand. If the load is completed without any interruption or
exception, the physical address is remembered, in Lock Physical Address
(LPA), and the Lock Flag (LF) is set to 1. LF is a non-architecturally
visible flag and is cleared whenever an interrupt or exception takes
place. LF is also cleared (atomically) whenever another process writes
to the LPA.
"scond" (Store Conditional) will write to the destination address if
and only if the LF is set to 1. When finished, with or without a write,
it atomically copies the LF value to ZF (Zero Flag).
These two instructions together provide the mechanism for entering a
critical section. The code snippet above comes from uClibc:
-----------------------
v3 (after Tom's remarks[2]):
handle_atomic_sequence()
- no need to initialize the std::vector with "{}"
- fix typo in comments: "conditial" -> "conditional"
- add braces to the body of "if" condition because of the comment line
arc_linux_software_single_step()
- make the performance slightly more efficient by moving a few
variables after the likely "return" point.
v2 (after Simon's remarks[3]):
- handle_atomic_sequence() gets a copy of an instruction instead of
a reference.
- handle_atomic_sequence() asserts if the given instruction is an llock.

If the user implements a TUI window in Python, and this window
responds to GDB events and then redraws its window contents then there
is currently an edge case which can lead to problems.
The Python API documentation suggests that calling methods like erase
or write on a TUI window (from Python code) will raise an exception if
the window is not valid.
And the description for is_valid says:
This method returns True when this window is valid. When the user
changes the TUI layout, windows no longer visible in the new layout
will be destroyed. At this point, the gdb.TuiWindow will no longer
be valid, and methods (and attributes) other than is_valid will
throw an exception.
From this I, as a user, would expect that if I did 'tui disable' to
switch back to CLI mode, then the window would no longer be valid.
However, this is not the case.
When the TUI is disabled the windows in the TUI are not deleted, they
are simply hidden. As such, currently, the is_valid method continues
to return true.
This means that if the users Python code does something like:
def event_handler (e):
global tui_window_object
if tui_window_object->is_valid ():
tui_window_object->erase ()
tui_window_object->write ("Hello World")
gdb.events.stop.connect (event_handler)
Then when a stop event arrives GDB will try to draw the TUI window,
even when the TUI is disabled.
This exposes two bugs. First, is_valid should be returning false in
this case, second, if the user forgot to add the is_valid call, then I
believe the erase and write calls should be throwing an
exception (when the TUI is disabled).
The solution to both of these issues is I think bound together, as it
depends on having a working 'is_valid' check.
There's a rogue assert added into tui-layout.c as part of this
commit. While working on this commit I managed to break GDB such that
TUI_CMD_WIN was nullptr, this was causing GDB to abort. I'm leaving
the assert in as it might help people catch issues in the future.

This commit was inspired by this mailing list patch:
https://sourceware.org/pipermail/gdb-patches/2021-January/174713.html
Currently, calling tui_layout_window::apply will add the window from
the layout object to the global tui_windows list.
Unfortunately, when the user runs the 'winheight' command, this calls
tui_adjust_window_height, which calls the tui_layout_base::adjust_size
function, which can then call tui_layout_base::apply. The consequence
of this is that when the user does 'winheight' duplicate copies of a
window can be added to the global tui_windows list.
The original patch fixed this by changing the apply function to only
update the global list some of the time.
This patch takes a different approach. The apply function no longer
updates the global tui_windows list. Instead a new virtual function
is added to tui_layout_base which is used to gather all the currently
applied windows into a vector. Finally tui_apply_current_layout is
updated to make use of this new function to update the tui_windows
list.
The benefits I see in this approach are, (a) the apply function now no
longer touches global state, this solves the immediate problem,
and (b) now that tui_windows is updated directly in the function
tui_apply_current_layout, we can drop the saved_tui_windows global.

gdb/tui: remove special handling of locator/status window
I accidentally remove a call to delete the tui window objects. Now
every time GDB changes tui layout it is leaking windows.
gdb/ChangeLog:
* tui/tui-layout.c (tui_apply_current_layout): Restore the delete
of the window objects.
