gdb: use gdb::optional instead of passing a pointer to gdb::array_view
Following on from the previous commit, this commit changes the API of
value_struct_elt to take gdb::optional<gdb::array_view<value *>>
instead of a pointer to the gdb::array_view.
This makes the optional nature of the array_view parameter explicit.
This commit is purely a refactoring commit, there should be no user
visible change after this commit.
I have deliberately kept this refactor separate from the previous two
commits as this is a more extensive change, and I'm not 100% sure that
using gdb::optional for the parameter type, instead of a pointer, is
going to be to everyone's taste. If there's push back on this patch
then this one can be dropped from the series.

an empty gdb::optional when calling value_struct_elt.

Remove redundant typedefs
I was inspired by this patch of Simon's: https://sourceware.org/pipermail/gdb-patches/2020-November/173522.html ... to remove other typedefs that are no longer necessary now that gdb uses C++. I didn't remove absolutely every one -- I didn't touch the tdep files. However, I removed many of them. In some cases, I removed an existing different struct tag. 2020-12-04 Tom Tromey <tromey@adacore.com> * linespec.c (struct linespec_token): Rename; remove typedef. * guile/scm-block.c (struct block_smob): Remove typedef.

gdb, gdbserver, gdbsupport: fix leading space vs tabs issues
Many spots incorrectly use only spaces for indentation (for example, there are a lot of spots in ada-lang.c). I've always found it awkward when I needed to edit one of these spots: do I keep the original wrong indentation, or do I fix it? What if the lines around it are also wrong, do I fix them too? I probably don't want to fix them in the same patch, to avoid adding noise to my patch. So I propose to fix as much as possible once and for all (hopefully). One typical counter argument for this is that it makes code archeology more difficult, because git-blame will show this commit as the last change for these lines. My counter counter argument is: when git-blaming, you often need to do "blame the file at the parent commit" anyway, to go past some other refactor that touched the line you are interested in, but is not the change you are looking for. So you already need a somewhat efficient way to do this. Using some interactive tool, rather than plain git-blame, makes this trivial. For example, I use "tig blame <file>", where going back past the commit that changed the currently selected line is one keystroke. It looks like Magit in Emacs does it too (though I've never used it). Web viewers of Github and Gitlab do it too. My point is that it won't really make archeology more difficult. The other typical counter argument is that it will cause conflicts with existing patches. That's true... but it's a one time cost, and those are not conflicts that are difficult to resolve. I have also tried "git rebase --ignore-whitespace", it seems to work well. Although that will re-introduce the faulty indentation, so one needs to take care of fixing the indentation in the patch after that (which is easy). gdb/ChangeLog: * aarch64-linux-tdep.c: Fix

gdb: remove TYPE_CODE macro
Remove TYPE_CODE, changing all the call sites to use type::code directly. This is quite a big diff, but this was mostly done using sed and coccinelle. A few call sites were done by hand. gdb/ChangeLog: * gdbtypes.h (TYPE_CODE): Remove. Change all call sites to use type::code instead. |

Change extension language pretty-printers to use value API
This changes the extension language pretty-printers to use the value API. Note that new functions were needed, for both Guile and Python. Currently both languages always wrap values by removing the values from the value chain. This makes sense to avoid strange behavior with watchpoints, and to avoid excessive memory use. However, when printing, it's important to leave the passed-in value untouched, in case pretty-printing does nothing -- that way the caller can still access it. gdb/ChangeLog 2020-03-13 Tom Tromey <tom@tromey.com> * valprint.c (do_val_print): Update. * python/python-internal.h (gdbpy_apply_val_pretty_printer): Take a struct value.

Remove la_get_string member
The la_get_string member of struct language_defn was intended to provide a way to fetch string data from a "string" object in a language-dependent way.

Avoid undefined behavior in Guile exception handling

Update copyright year range in all GDB files.
This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files. |

Use gdb:array_view in call_function_by_hand & friends
This replaces a few uses of pointer+length with gdb::array_view, in call_function_by_hand and related code. Unfortunately, due to -Wnarrowing, there are places where we can't brace-initialize an gdb::array_view without an ugly-ish cast. To avoid the cast, this patch introduces a gdb::make_array_view function. Unit tests included. This patch in isolation may not look so interesting, due to gdb::make_array_view uses, but I think it's still worth it. Some of the gdb::make_array_view calls disappear down the series, and others could be eliminated with more (non-trivial) gdb::array_view detangling/conversion (e.g. code around eval_call). See this as a "we have to start somewhere" patch. gdb/ChangeLog: 2018-11-21 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_evaluate_subexp): Adjust to pass an array_view. * common/array-view.h (make_array_view): New. * compile/compile-object-run.c (compile_object_run): Adjust to pass an array_view. * elfread.c (elf_gnu_ifunc_resolve_addr): Adjust. * eval.c (eval_call): Adjust to pass an array_view.

Eliminate most remaining cleanups under gdb/guile/
The main complication with the Guile code is that we have two types of exceptions to consider. GDB/C++ exceptions, and Guile/SJLJ exceptions. Code that is facing the Guile interpreter must not throw GDB exceptions, instead Scheme exceptions must be thrown. Also, because Guile exceptions are SJLJ based, Guile-facing code must not use local objects with dtors, unless wrapped in a scope with a TRY/CATCH, because the dtors won't otherwise be run when a Guile exceptions is thrown. This commit adds a new gdbscm_wrap wrapper function than encapsulates a pattern I noticed in many of the functions using GDBSCM_HANDLE_GDB_EXCEPTION_WITH_CLEANUPS. The wrapper is written such that you can pass either a lambda to it, or a function plus a variable number of forwarded args. I used a lambda when its body would be reasonably short, and a separate function in the larger cases. This also convers a few functions that were using GDBSCM_HANDLE_GDB_EXCEPTION to use gdbscm_wrap too because they followed a similar pattern. A few cases of make_cleanup calls are replaced with explicit xfree calls. The make_cleanup/do_cleanups calls in those cases are pointless, because do_cleanups won't be called when a Scheme exception is thrown. We also have a couple cases of Guile-facing code using RAII-type objects to manage memory, but those are incorrect, exactly because their dtor won't be called if a Guile exception is thrown. gdb/ChangeLog: 2018-07-18 Pedro Alves <palves@redhat.com> * guile/guile-internal.h: Add comment about mixing GDB and Scheme exceptions.

This changes read_string's "buffer" out-parameter to be a unique_xmalloc_ptr, then updates the users. This allows for the removal of some cleanups.

Introduce a gdb_ref_ptr specialization for struct value
struct value is internally reference counted and so, while it also has some ownership rules unique to it, it makes sense to use a gdb_ref_ptr when managing it automatically. This patch removes the existing unique_ptr specialization in favor of a reference-counted pointer. It also introduces two other clarifications: 1. Rename value_free to value_decref, which I think is more in line with what the function actually does; and 2. Change release_value to return a gdb_ref_ptr. This change allows us to remove the confusing release_value_or_incref function, primarily by making it much simpler to reason about the result of release_value. gdb/ChangeLog 2018-04-06 Tom Tromey <tom@tromey.com> * varobj.c (varobj_clear_saved_item) (update_dynamic_varobj_children, install_new_value, ~varobj): Update. * value.h (value_incref): Move declaration earlier.

Target FP: Handle interfaces to scripting languages
The last remaing use for DOUBLEST is in the code that interfaces to the scripting languages (Python and Guile). The problem here is that we expose interfaces to convert a GDB value to and from native values of floating-point type in those languages, and those by definition use the host floating-point format. While we cannot completely eliminate conversions to/from the host floating-point format here, we still need to get rid of the uses of value_as_double / value_from_double, since those will go away. This patch implements two new target-float.c routine: - target_float_to_host_double - target_float_from_host_double which convert to/from a host "double". Those should only ever be used where a host "double" is mandated by an external interface. gdb/ChangeLog: 2017-11-06 Ulrich Weigand <uweigand@de.ibm.com> * target-float.c (floatformat_to_host_double): New function.

Fix sometimes-uninitialized warning in gdbscm_value_address
I am getting this warning with clang:
/home/emaisin/src/binutils-gdb/gdb/guile/scm-value.c:439:11: error: variable 'address' is used uninitialized whenever 'if' condition is false [-Werror,-Wsometimes-uninitialized]
if (res_val != NULL)
^~~~~~~~~~~~~~~

^~~~~~~~~~~~~~~~~~~~
/home/emaisin/src/binutils-gdb/gdb/guile/scm-value.c:427:18: note: initialize the variable 'address' to silence this warning
SCM address;
^
= nullptr
We can get rid of it with a small refactoring. I think it's a bit
cleaner/safer to initialize address with a pessimistic value and assign
it on success. Then there's no chance of using it uninitialized. If I
understand correctly, the NULL check on res_val was to check whether
value_addr threw, and that if value_addr returns without throwing, the
result will never be NULL. If that's true, we can skip the res_val
variable.
Tested by running gdb.guile/*.exp locally.

* guile/scm-value.c (gdbscm_value_address): Initialize address,

Stop assuming no-debug-info functions return int
The fact that GDB defaults to assuming that functions return int, when
it has no debug info for the function has been a recurring source of
user confusion. Recently this came up on the errno pretty printer
discussions. Shortly after, it came up again on IRC, with someone
wondering why does getenv() in GDB return a negative int:
(gdb) p getenv("PATH")
$1 = -6185
This question (with s/getenv/random-other-C-runtime-function) is a FAQ
on IRC.
The reason for the above is:
(gdb) p getenv
$2 = {<text variable, no debug info>} 0x7ffff7751d80 <getenv>
(gdb) ptype getenv
type = int ()
... which means that GDB truncated the 64-bit pointer that is actually
returned from getent to 32-bit, and then sign-extended it:
(gdb) p /x -6185
$6 = 0xffffe7d7
The workaround is to cast the function to the right type, like:
(gdb) p ((char *(*) (const char *)) getenv) ("PATH")
$3 = 0x7fffffffe7d7 "/usr/local/bin:/"...
IMO, we should do better than this.
I see the "assume-int" issue the same way I see printing bogus values
for optimized-out variables instead of "<optimized out>" -- I'd much
rather that the debugger tells me "I don't know" and tells me how to
fix it than showing me bogus misleading results, making me go around
tilting at windmills.
If GDB prints a signed integer when you're expecting a pointer or
aggregate, you at least have some sense that something is off, but
consider the case of the function actually returning a 64-bit integer.
For example, compile this without debug info:
unsigned long long
function ()
{
return 0x7fffffffffffffff;
}
Currently, with pristine GDB, you get:
(gdb) p function ()
$1 = -1 # incorrect
(gdb) p /x function ()
$2 = 0xffffffff # incorrect
maybe after spending a few hours debugging you suspect something is
wrong with that -1, and do:
(gdb) ptype function
type = int ()
and maybe, just maybe, you realize that the function actually returns
unsigned long long. And you try to fix it with:
(gdb) p /x (unsigned long long) function ()
$3 = 0xffffffffffffffff # incorrect
... which still produces the wrong result, because GDB simply applied
int to unsigned long long conversion. Meaning, it sign-extended the
integer that it extracted from the return of the function, to 64-bits.
and then maybe, after asking around on IRC, you realize you have to
cast the function to a pointer of the right type, and call that. It
won't be easy, but after a few missteps, you'll get to it:
..... (gdb) p /x ((unsigned long long(*) ()) function) ()
$666 = 0x7fffffffffffffff # finally! :-)
So to improve on the user experience, this patch does the following
(interrelated) things:
- makes no-debug-info functions no longer default to "int" as return
type. Instead, they're left with NULL/"<unknown return type>"
return type.
(gdb) ptype getenv
type = <unknown return type> ()
- makes calling a function with unknown return type an error.
(gdb) p getenv ("PATH")
'getenv' has unknown return type; cast the call to its declared return type
- and then to make it easier to call the function, makes it possible
to _only_ cast the return of the function to the right type,
instead of having to cast the function to a function pointer:
(gdb) p (char *) getenv ("PATH") # now Just Works
$3 = 0x7fffffffe7d7 "/usr/local/bin:/"...
(gdb) p ((char *(*) (const char *)) getenv) ("PATH") # continues working
$4 = 0x7fffffffe7d7 "/usr/local/bin:/"...
I.e., it makes GDB default the function's return type to the type
of the cast, and the function's parameters to the type of the
arguments passed down.
After this patch, here's what you'll get for the "unsigned long long"
example above:
(gdb) p function ()
'function' has unknown return type; cast the call to its declared return type
(gdb) p /x (unsigned long long) function ()
$4 = 0x7fffffffffffffff # correct!
Note that while with "print" GDB shows the name of the function that
has the problem:
(gdb) p getenv ("PATH")
'getenv' has unknown return type; cast the call to its declared return type
which can by handy in more complicated expressions, "ptype" does not:
(gdb) ptype getenv ("PATH")
function has unknown return type; cast the call to its declared return type
This will be fixed in the next patch.

Eliminate make_cleanup_ui_file_delete / make ui_file a class hierarchy
This patch starts from the desire to eliminate
make_cleanup_ui_file_delete, but then goes beyond. It makes ui_file &
friends a real C++ class hierarchy, and switches temporary
ui_file-like objects to stack-based allocation.
- mem_fileopen -> string_file
mem_fileopen is replaced with a new string_file class that is treated
as a value class created on the stack. This alone eliminates most
make_cleanup_ui_file_delete calls, and, simplifies code a whole lot
(diffstat shows around 1k loc dropped.)
string_file's internal buffer is a std::string, thus the "string" in
the name. This simplifies the implementation much, compared to
mem_fileopen, which managed growing its internal buffer manually.
- ui_file_as_string, ui_file_strdup, ui_file_obsavestring all gone
The new string_file class has a string() method that provides direct
writable access to the internal std::string buffer. This replaced
ui_file_as_string, which forced a copy of the same data the stream had
inside. With direct access via a writable reference, we can instead
move the string out of the string_stream, avoiding deep string
copying.
Related, ui_file_xstrdup calls are replaced with xstrdup'ping the
stream's string, and ui_file_obsavestring is replaced by
obstack_copy0.
With all those out of the way, getting rid of the weird ui_file_put
mechanism was possible.
- New ui_file::printf, ui_file::puts, etc. methods
These simplify / clarify client code. I considered splitting
client-code changes, like these, e.g.:
- stb = mem_fileopen ();
- fprintf_unfiltered (stb, "%s%s%s",
- _("The valid values are:\n"),
- regdesc,
- _("The default is \"std\"."));
+ string_file stb;
+ stb.printf ("%s%s%s",
+ _("The valid values are:\n"),
+ regdesc,
+ _("The default is \"std\"."));
In two steps, with the first step leaving fprintf_unfiltered (etc.)
calls in place, and only afterwards do a pass to change all those to
call stb.printf etc.. I didn't do that split, because (when I tried),
it turned out to be pointless make-work: the first pass would have to
touch the fprintf_unfiltered line anyway, to replace "stb" with
"&stb".
- gdb_fopen replaced with stack-based objects
This avoids the need for cleanups or unique_ptr's. I.e., this:
struct ui_file *file = gdb_fopen (filename, "w");
if (filename == NULL)
perror_with_name (filename);
cleanups = make_cleanup_ui_file_delete (file);
// use file.
do_cleanups (cleanups);
is replaced with this:
stdio_file file;
if (!file.open (filename, "w"))
perror_with_name (filename);
// use file.
- odd contorsions in null_file_write / null_file_fputs around when to
call to_fputs / to_write eliminated.
- Global null_stream object
A few places that were allocating a ui_file in order to print to
"nowhere" are adjusted to instead refer to a new 'null_stream' global
stream.
- TUI's tui_sfileopen eliminated. TUI's ui_file much simplified
The TUI's ui_file was serving a dual purpose. It supported being used
as string buffer, and supported being backed by a stdio FILE. The
string buffer part is gone, replaced by using of string_file. The
'FILE *' support is now much simplified, by making the TUI's ui_file
inherit from stdio_file.

Replace some xmalloc-family functions with XNEW-family ones
This patch is part of the make-gdb-buildable-in-C++ effort. The idea is to change some calls to the xmalloc family of functions to calls to the equivalents in the XNEW family. This avoids adding an explicit cast, so it keeps the code a bit more readable. Some of them also map relatively well to a C++ equivalent (XNEW (struct foo) -> new foo), so it will be possible to do scripted replacements if needed. I only changed calls that were obviously allocating memory for one or multiple "objects". Allocation of variable sizes (such as strings or buffer handling) will be for later (and won't use XNEW). - xmalloc (sizeof (struct foo)) -> XNEW (struct foo) - xmalloc (num * sizeof (struct foo)) -> XNEWVEC (struct foo, num) - xcalloc (1, sizeof (struct foo)) -> XCNEW (struct foo) - xcalloc (num, sizeof (struct foo)) -> XCNEWVEC (struct foo, num) - xrealloc (p, num * sizeof (struct foo) -> XRESIZEVEC (struct foo, p, num) - obstack_alloc (ob, sizeof (struct foo)) -> XOBNEW (ob, struct foo) - obstack_alloc (ob, num * sizeof (struct foo)) -> XOBNEWVEC (ob, struct foo, num) - alloca (sizeof (struct foo)) -> XALLOCA (struct foo) - alloca (num * sizeof (struct foo)) -> XALLOCAVEC (struct foo, num) Some instances of xmalloc followed by memset to zero the buffer were replaced by XCNEW or XCNEWVEC. I regtested on x86-64, Ubuntu 14.04, but the patch touches many architecture-specific files.

Remove CHECK_TYPEDEF, use check_typedef instead
I think that the CHECK_TYPEDEF macro is not necessary, and even a bit
annoying. It makes unclear the fact that the "type" variables gets
overwritten. It has actually bitten me a few times. I think the
following, explicit form, is better.
type = check_typedef (type);
This patches changes all instances of CHECK_TYPEDEF for an equivalent
call to check_typedef. The bulk of the change was done with this sed:
sed -i 's/CHECK_TYPEDEF (\([^)]*\));/\1 = check_typedef (\1);/' <file>.c
The ChangeLog was generated using David Malcom's generate_changelog.py.
I manually fixed those places where it gets the wrong function name,
hopefully all of them.
The patch was built-tested, and I ran a few smoke tests.

Split TRY_CATCH into TRY + CATCH
This patch splits the TRY_CATCH macro into three, so that we go from
this:
~~~
volatile gdb_exception ex;
TRY_CATCH (ex, RETURN_MASK_ERROR)
{
}
if (ex.reason < 0)
{
}
~~~
to this:
~~~
TRY
{
}
CATCH (ex, RETURN_MASK_ERROR)
{
}
END_CATCH
~~~
Thus, we'll be getting rid of the local volatile exception object, and
declaring the caught exception in the catch block.
This allows reimplementing TRY/CATCH in terms of C++ exceptions when
building in C++ mode, while still allowing to build GDB in C mode
(using setjmp/longjmp), as a transition step.
TBC, after this patch, is it _not_ valid to have code between the TRY
and the CATCH blocks, like:
TRY
{
}
// some code here.
CATCH (ex, RETURN_MASK_ERROR)
{
}
END_CATCH
Just like it isn't valid to do that with C++'s native try/catch.
By switching to creating the exception object inside the CATCH block
scope, we can get rid of all the explicitly allocated volatile
exception objects all over the tree, and map the CATCH block more
directly to C++'s catch blocks.
The majority of the TRY_CATCH -> TRY+CATCH+END_CATCH conversion was
done with a script, rerun from scratch at every rebase, no manual
editing involved. After the mechanical conversion, a few places
needed manual intervention, to fix preexisting cases where we were
using the exception object outside of the TRY_CATCH block, and cases
where we were using "else" after a 'if (ex.reason) < 0)' [a CATCH
after this patch]. The result was folded into this patch so that GDB
still builds at each incremental step.
END_CATCH is necessary for two reasons:
First, because we name the exception object in the CATCH block, which
requires creating a scope, which in turn must be closed somewhere.
Declaring the exception variable in the initializer field of a for
block, like:
#define CATCH(EXCEPTION, mask) \
for (struct gdb_exception EXCEPTION; \
exceptions_state_mc_catch (&EXCEPTION, MASK); \
EXCEPTION = exception_none)
would avoid needing END_CATCH, but alas, in C mode, we build with C90,
which doesn't allow mixed declarations and code.
Second, because when TRY/CATCH are wired to real C++ try/catch, as
long as we need to handle cleanup chains, even if there's no CATCH
block that wants to catch the exception, we need for stop at every
frame in the unwind chain and run cleanups, then rethrow. That will
be done in END_CATCH.
After we require C++, we'll still need TRY/CATCH/END_CATCH until
cleanups are completely phased out -- TRY/CATCH in C++ mode will
save/restore the current cleanup chain, like in C mode, and END_CATCH
catches otherwise uncaugh exceptions, runs cleanups and rethrows, so
that C++ cleanups and exceptions can coexist.
IMO, this still makes the TRY/CATCH code look a bit more like a
newcomer would expect, so IMO worth it even if we weren't considering
C++.
