This patch adds support for DW_AT_main_subprogram.
This is PR symtab/16264.
DW_AT_main_subprogram is used to mark a program's entry point. GCC
can emit this, and I hope to change the Rust compiler to emit it as
well.
GDB already supports an older, pre-DWARF 4 convention adopted by
FORTRAN compilers, namely to emit DW_AT_calling_convention for the
"main" function. However, I think this support in GDB had a small
bug, in that it seems to rely on the DW_AT_name being read before
DW_AT_calling_convention. This patch fixes this as well.
Built and regtested on x86-64 Fedora 24 and the buildbot. New test
case included.

The DW_AT_data_bit_offset attribute was introduced by DWARF V4 and
allows specifying the offset of a data member within its containing
entity. But although the new attribute was intended to replace
DW_AT_bit_offset for this purpose, GDB ignores it, and thus GCC still
emits DW_AT_bit_offset instead. See also
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71669.
This change fixes GDB's lack of support for DW_AT_data_bit_offset and
adds an appropriate test case.

This replaces most of the remaining ui_file_xstrdup calls with
ui_file_as_string calls. Whenever a call was replaced, that led to a
cascade of other necessary adjustments throughout, to make the code
use std::string instead of raw pointers. And then whenever I added a
std::string as member of a struct, I needed to adjust
allocation/destruction of said struct to use new/delete instead of
xmalloc/xfree.
The stopping point was once gdb built again. These doesn't seem to be
a way to reasonably split this out further.
Maybe-not-obvious changes:
- demangle_for_lookup returns a cleanup today. To get rid of that,
and avoid unnecessary string dupping/copying, this introduces a
demangle_result_storage type that the caller instantiates and
passes to demangle_for_lookup.
- Many methods returned a "char *" to indicate that the caller owns
the memory and must free it. Those are switched to return a
std::string instead. Methods that return a "view" into some
internal string return a "const char *" instead. I.e., we only
copy/allocate when necessary.

This patch removes the Java support from gdb. gcj has not seen much
development or use for years now, and was recently removed from GCC.
This patch changes gdb to follow; in the unlikely event that there are
still users using gcj, they can continue to use an older gdb to debug.
Or, they can debug in C++ mode.
Built and regtested on x86-64 Fedora 24.

At this point, all TYPE_CODE_FLT types carry their floating-point format,
except for those creating from reading DWARF or stabs debug info. Those
will be addressed by this commit.
The main issue here is that we actually have to determine which floating-
point format to use. Currently, we only have the type length as input
to this decision. In the future, we may hopefully get --at least in
DWARF-- additional information to help disambiguate multiple different
formats of the same length. For now, we can still look at the type name
as a hint.
This decision logic is encapsulated in a gdbarch callback to allow
platform-specific overrides. The default implementation use the same
logic (compare type length against the various gdbarch_..._bit sizes)
that is currently implemented in floatformat_from_length.
With this commit, all platforms still use the default logic, so there
should be no actual change in behavior. A follow-on commit will add
support for __float128 on Intel and Power.
Once dwarf2read.c and stabsread.c make use of the new callback to
determine floating-point formats, we're now sure every TYPE_CODE_FLT
type will always carry its format. The commit therefore adds asserts
to verify_floatformat to ensure new code will continue to always
provide formats, and removes the code in floatformat_from_type that
used to handle types with a NULL TYPE_FLOATFORMAT.

This adds a number of helper routines for creating objfile-owned types;
these correspond 1:1 to the already existing helper routines for creating
gdbarch-owned types, and are intended to be used instead of init_type.
A shared fragment of init_float_type and arch_float_type is extracted into
a separate subroutine verify_subroutine.
The commit also brings the interface of init_type in line with the one for
arch_type. In particular, this means removing the FLAGS argument; callers
now set the required flags directly. (Since most callers use the new
helper routines, very few callers actually need to set any additional
flags directly any more.)
Note that this means all the TYPE_FLAGS_... defined are no longer needed
anywhere; they will be removed by a follow-on commit.
All users of init_type are changed to use on of the new helpers where
possible. No functional change intended.

Currently gdb supports DW_OP_GNU_push_tls_address, but not
DW_OP_form_tls_address. I think it would be better if the toolchain
as a whole moved to using the standard opcode, and the prerequisite to
this is getting gdb to recognize it.
GCC can sometimes emit DW_OP_form_tls_address for emultls targets. As
far as I know, nobody has ever tried this with gdb (since it wouldn't
work at all).
I don't think there's a major drawback to using a single opcode for
all targets, because computing the location of a thread-local is
already target specific.
This is PR gdb/11616.
I don't know how to write a test case for this; though it's worth
noting that there aren't explicit tests for DW_OP_GNU_push_tls_address
either -- and if I change GCC, these paths will be tested to the same
extent they are now.

PR rust/20162 started life as a reminder to test gdb with versions of
rust after 1.8; but now concerns some gdb regressions seen with rust
1.10 ("beta") and 1.11 ("nightly").
The failures turn out to be a discrepancy between how rustc emits
DWARF and how gdb interprets it. In particular, rustc will emit DWARF
like:
<2><bc>: Abbrev Number: 9 (DW_TAG_structure_type)
<bd> DW_AT_name : (indirect string, offset: 0x46a): HasMethods
<c1> DW_AT_byte_size : 4
...
<3><cc>: Abbrev Number: 11 (DW_TAG_subprogram)
...
<df> DW_AT_name : (indirect string, offset: 0x514f): new
gdb wants to see a separate top-level DW_TAG_subprogram that refers to
this one via DW_AT_specification; but rustc doesn't emit one. By my
reading of DWARF 4 5.5.7, this is ok, and gdb is incorrect here.
Fixing this involved a new case in scan_partial_symbols, and then a
further change in process_structure_scope to account for the fact
that, in Rust, such functions are not methods and should not be
attached to the structure type.
Next, it turns out that rust is emitting bad values for
DW_AT_linkage_name, e.g.:
<db> DW_AT_linkage_name: (indirect string, offset: 0x422): _ZN7methods8{{impl}}3newE
The the "{{impl}}" stuff is apparently some side effect of a change to
the compiler's internal representation. Oops!
This also had a simple fix -- disregard these mangled names.
With these changes, there are no regressions in the gdb Rust tests
with either 1.10 or 1.11. 1.9, the stable release, is still pretty
broken, but I think there's nothing much to do about that.
These changes are a bit hackish, but no worse, I think, than other
kinds of quirk handling already done in the DWARF parser. I have
reported all the rustc bugs upstream. I plan to remove these hacks
from gdb some suitable time after they have been fixed in released
versions of Rust.

This patch consolidates the (possibly-questionable) spots where we
remove a declaration but continue to call some function for side
effects. In a couple of cases it wasn't entirely clear to me that
this mattered; and in some other cases it might be more aesthetically
pleasing to use ATTRIBUTE_UNUSED. So, I broke this out into a
separate patch for simpler review.

GDB: read_lexical_block_scope
/* Ignore blocks with missing or invalid low and high pc attributes. */
[...]
if (!dwarf2_get_pc_bounds (die, &lowpc, &highpc, cu, NULL))
return;
But sometimes there is:
FAIL: gcc-5.3.1-6.fc23.x86_64
<2><92>: Abbrev Number: 11 (DW_TAG_lexical_block)
<3><9c>: Abbrev Number: 13 (DW_TAG_structure_type)
<9d> DW_AT_name : (indirect string, offset: 0x3c): <lambda()>
[...]
Where DW_TAG_lexical_block has no attributes. Such whole subtree is currently
dropped by GDB while I think it should just import all its children DIEs.
It even XFAIL->XPASSes gdb.ada/out_of_line_in_inlined.exp:

It is possible to use multiple base addresses within a single address
range series, within the .debug_ranges section. The following is a
simplified example for 32-bit addresses:
.section ".debug_ranges"
.4byte 0xffffffff
.4byte BASE_1
.4byte START_OFFSET_1
.4byte END_OFFSET_1
.4byte START_OFFSET_2
.4byte END_OFFSET_2
.4byte 0xffffffff
.4byte BASE_2
.4byte START_OFFSET_3
.4byte END_OFFSET_3
.4byte 0
.4byte 0
In this example START/END 1 and 2 are relative to BASE_1, while
START/END 3 are relative to BASE_2.
Currently gdb does not correctly parse this DWARF, resulting in
corrupted address range information. This commit fixes this issue, and
adds a new test to cover this case.
In order to support testing of this feature extensions were made to the
testsuite dwarf assembler, additional functionality was added to the
.debug_line generation function, and a new function for generating the
.debug_ranges section was added.

Using the gdb.ada/var_rec_arr.exp test, where the program declares
an array of variant records...
type Record_Type (I : Small_Type := 0) is record
S : String (1 .. I);
end record;
type Array_Type is array (Integer range <>) of Record_Type;
... and then a variable A1 of type Array_Type, the following command
ocassionally trigger an internal error trying to allocate more memory
than we have left:
(gdb) ptype a1(1)
[...]/utils.c:1089: internal-error: virtual memory exhausted.
A problem internal to GDB has been detected,
[...]
What happens is that recent versions of GNAT are able to generate
DWARF expressions for type Record_Type, and therefore the record's
DW_AT_byte_size is not a constant, which unfortunately breaks
an assumption made by dwarf2read.c:read_structure_type when it does:
attr = dwarf2_attr (die, DW_AT_byte_size, cu);
if (attr)
{
TYPE_LENGTH (type) = DW_UNSND (attr);
}
As a result of this, when ada_evaluate_subexp tries to create
a value_zero for a1(1) while processing the OP_FUNCALL operator
as part of evaluating the subscripting operation in no-side-effect
mode, we try to allocate a value with a bogus size, potentially
triggering the out-of-memory internal error.
This patch avoids this issue by setting the length to zero in
this case. Until we decide to start supporting dynamic type
lengths in GDB's type struct, and it's not clear yet that
this is worth the effort (see added comment), that's probably
the best we can do.
gdb/ChangeLog:
* dwarf2read.c (read_structure_type): Set the type's length
to zero if it has a DW_AT_byte_size attribute which is not
a constant.

* testsuite/gdb.ada/var_rec_arr.exp: Add "ptype a1(1)" test.

Fortran provide types whose values may be dynamically allocated
or associated with a variable under explicit program control.
The purpose of this commit is:
* to read allocated/associated DWARF tags and store them in
the dynamic property list of main_type.
* enable GDB to print the value of a dynamic array in Fortran
in case the type is allocated or associated (pointer to
dynamic array).
Examples:
(gdb) p vla_not_allocated
$1 = <not allocated>
(gdb) p vla_allocated
$1 = (1, 2, 3)
(gdb) p vla_ptr_not_associated
$1 = <not associated>
(gdb) p vla_ptr_associated
$1 = (1, 2, 3)
Add basic test coverage for most dynamic array use-cases in Fortran.
The commit contains the following tests:
* Ensure that values of Fortran dynamic arrays
can be evaluated correctly in various ways and states.
* Ensure that Fortran primitives can be evaluated
correctly when used as a dynamic array.
* Dynamic arrays passed to subroutines and handled
in different ways inside the routine.
* Ensure that the ptype of dynamic arrays in
Fortran can be printed in GDB correctly.
* Ensure that dynamic arrays in different states
(allocated/associated) can be evaluated.
* Dynamic arrays passed to functions and returned from
functions.
* History values of dynamic arrays can be accessed and
printed again with the correct values.
* Dynamic array evaluations using MI protocol.
* Sizeof output of dynamic arrays in various states.
The patch was tested using the test suite on Ubuntu 12.04 64bit.

Note: I needed to split this patch in two, otherwise it's too big for
the mailing list.
This patch adds explicit casts to situations where a void pointer is
assigned to a pointer to the "real" type. Building in C++ mode requires
those assignments to use an explicit cast. This includes, for example:
- callback arguments (cleanups, comparison functions, ...)
- data attached to some object (objfile, program space, etc) in the form
of a void pointer
- "user data" passed to some function
This patch comes from the commit "(mostly) auto-generated patch to insert
casts needed for C++", taken from Pedro's C++ branch.
Only files built on x86 with --enable-targets=all are modified, so the
native files for other arches will need to be dealt with separately.
I built-tested this with --enable-targets=all and reg-tested. To my
surprise, a test case (selftest.exp) had to be adjusted.
Here's the ChangeLog entry. Again, this was relatively quick to make
despite the length, thanks to David Malcom's script, although I don't
believe it's very useful information in that particular case...

Most allocation functions (if not all) return a void* pointing to the
allocated memory. In C++, we need to add an explicit cast when
assigning the result to a pointer to another type (which is the case
more often than not).
The content of this patch is taken from Pedro's branch, from commit
"(mostly) auto-generated patch to insert casts needed for C++". I
validated that the changes make sense and manually reflowed the code to
make it respect the coding style. I also found multiple places where I
could use XNEW/XNEWVEC/XRESIZEVEC/etc.
Thanks a lot to whoever did that automated script to insert casts, doing
it completely by hand would have taken a ridiculous amount of time.
Only files built on x86 with --enable-targets=all are modified. This
means that all other -nat.c files are untouched and will have to be
dealt with later by using appropiate compilers. Or maybe we can try to
build them with a regular g++ just to know where to add casts, I don't
know.
I built-tested this with --enable-targets=all and reg-tested.
Here's the changelog entry, which was not too bad to make despite the
size, thanks to David Malcom's script. I fixed some bits by hand, but
there might be some wrong parts left (hopefully not).

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. For those I'll have to rely on the
buildbot or people complaining that I broke their gdb.

GDB's current behavior when dealing with non-local references in the
context of nested fuctions is approximative:
- code using valops.c:value_of_variable read the first available stack
frame that holds the corresponding variable (whereas there can be
multiple candidates for this);
- code directly relying on read_var_value will instead read non-local
variables in frames where they are not even defined.
This change adds the necessary context to symbol reads (to get the block
they belong to) and to blocks (the static link property, if any) so that
GDB can make the proper decisions when dealing with non-local varibale
references.

Here, in dwarfread.c:process_full_comp_unit:
/* Set symtab language to language from DW_AT_language. If the
compilation is from a C file generated by language preprocessors, do
not set the language if it was already deduced by start_subfile. */
if (!(cu->language == language_c
&& COMPUNIT_FILETABS (cust)->language != language_c))
COMPUNIT_FILETABS (cust)->language = cu->language;
in case start_subfile doesn't manage to deduce a language
COMPUNIT_FILETABS(cust)->language ends up as language_unknown, not
language_c. So the condition above evals false and we never set the
language from the cu's language.

This change introduces a new function, dwarf2_string_attr(), which is
a wrapper for dwarf2_attr(). dwarf2read.c has been updated to
call dwarf2_string_attr in most instances where a string-valued
attribute is decoded to produce a string value. In most cases, it
simplifies the code; in some instances, the complexity of the code
remains unchanged.
I performed this change by looking for instances where the
result of DW_STRING was used in an assignment. Many of these
had a pattern which (roughly) looks something like this:
struct attribute *attr = NULL;
attr = dwarf2_attr (die, name, cu);
if (attr != NULL && DW_STRING (attr))
{
const char *str;
...
str = DW_STRING (attr);
... /* Use str in some fashion. */
}
Code of this form is transformed to look like this instead:
const char *str;
str = dwarf2_string_attr (die, name, cu)
if (str != NULL)
{
...
/* Use str in some fashion. */
...
}
In addition to invoking dwarf2_attr() and DW_STRING(),
dwarf2_string_attr() checks to make sure that the attribute's
`form' field matches one of DW_FORM_strp, DW_FORM_string, or
DW_FORM_GNU_strp_alt. If it does not match one of these forms,
it will return a NULL value in addition to calling complaint().
An earlier version of this patch did this type checking for one
particular instance where a string attribute was being decoded.
The situation that I was attempting to handle in that earlier patch is
this:
The Texas Instruments compiler uses the encoding for
DW_AT_MIPS_linkage_name for other purposes. TI uses the encoding,
0x2007, for TI_AT_TI_end_line which, unlike DW_AT_MIPS_linkage_name,
does not have a string-typed value. In this instance, GDB was attempting
to use an integer value as a string pointer, with predictable results.
(GDB would die with a segmentation fault.)
I've added a test which reproduces the problem that I was orignally
wanting to fix. It uses DW_AT_MIPS_linkage name with an associate
value which is a string, and again, where the value is a small
integer.
My test case causes GDB to segfault in an unpatched GDB. There
will be two PASSes in a patched GDB.
Unpatched GDB:
(gdb) ptype f
ERROR: Process no longer exists
UNRESOLVED: gdb.dwarf2/dw2-bad-mips-linkage-name.exp: ptype f
ERROR: Couldn't send ptype g to GDB.
UNRESOLVED: gdb.dwarf2/dw2-bad-mips-linkage-name.exp: ptype g

Consider the following declaration:
function Foo (I : Integer) return Integer renames Pack.Bar;
As Foo is not materialized as a routine whose name is derived from Foo,
GDB currently cannot use it:
(gdb) print foo(0)
No definition of "foo" in current context.
However, compilers can emit DW_TAG_imported_declaration in order to
materialize the fact that Foo is actually another name for Pack.Bar.

This patch is mostly extracted from Pedro's C++ branch. It adds explicit
casts from integer to enum types, where it is really the intention to do
so. This could be because we are ...
* iterating on enum values (we need to iterate on an equivalent integer)
* converting from a value read from bytes (dwarf attribute, agent
expression opcode) to the equivalent enum
* reading the equivalent integer value from another language (Python/Guile)
An exception to that is the casts in regcache.c. It seems to me like
struct regcache's register_status field could be a pointer to an array of
enum register_status. Doing so would waste a bit of memory (4 bytes
used by the enum vs 1 byte used by the current signed char, for each
register). If we switch to C++11 one day, we can define the underlying
type of an enum type, so we could have the best of both worlds.
