The patch to make GDB stop assuming functions return int left GDB with
an inconsistency. While with normal expression evaluation the
"unknown return type" error shows the name of the function that misses
debug info:
(gdb) p getenv ("PATH")
'getenv' has unknown return type; cast the call to its declared return type
^^^^^^
which is 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 commit builds on the new OP_VAR_MSYM_VALUE to fix it, by making
OP_FUNCALL extract the function name from the symbol stored in
OP_VAR_VALUE/OP_VAR_MSYM_VALUE. We now get the same error in "print"
vs "ptype":
(gdb) ptype getenv()
'getenv' has unknown return type; cast the call to its declared return type
(gdb) p getenv()
'getenv' has unknown return type; cast the call to its declared return type

The previous patch left GDB with an inconsistency. While with normal
expression evaluation the "unknown return type" error shows the name
of the function that misses debug info:
(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 commit is a step toward fixing it.
The problem is that while evaluating the expression above, we have no
reference to the minimal symbol where we could extract the name from.
This is because the resulting expression tree has no reference to the
minsym at all. During parsing, the type and address of the minsym are
extracted and an UNOP_MEMVAL / UNOP_MEMVAL_TLS operator is generated
(see write_exp_elt_msym). With "set debug expression", here's what
you see:
0 OP_FUNCALL Number of args: 0
3 UNOP_MEMVAL Type @0x565334a51930 (<text variable, no debug info>)
6 OP_LONG Type @0x565334a51c60 (__CORE_ADDR), value 140737345035648 (0x7ffff7751d80)
The "print" case finds the function name, because
call_function_by_hand looks up the function by address again.
However, for "ptype", we don't reach that code, because obviously we
don't really call the function.
Unlike minsym references, references to variables with debug info have
a pointer to the variable's symbol in the expression tree, with
OP_VAR_VALUE:
(gdb) ptype main()
...
0 OP_FUNCALL Number of args: 0
3 OP_VAR_VALUE Block @0x0, symbol @0x559bbbd9b358 (main(int, char**))
...
so I don't see why do minsyms need to be different. So to prepare for
fixing the missing function name issue, this commit adds a new
OP_VAR_MSYM_VALUE operator that mimics OP_VAR_VALUE, except that it's
for minsyms instead of debug symbols. For infcalls, we now get
expressions like these:
0 OP_FUNCALL Number of args: 0
3 OP_VAR_MSYM_VALUE Objfile @0x1e41bf0, msymbol @0x7fffe599b000 (getenv)
In the following patch, we'll make OP_FUNCALL extract the function
name from the symbol stored in OP_VAR_VALUE/OP_VAR_MSYM_VALUE.
OP_VAR_MSYM_VALUE will be used more in a later patch in the series
too.

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.

(Ref: https://sourceware.org/ml/gdb/2017-06/msg00020.html)
Assuming int_t is a typedef to int:
typedef int int_t;
gdb currently loses this expression's typedef:
(gdb) p (int_t) 0
$1 = 0
(gdb) whatis $1
type = int
or:
(gdb) whatis (int_t) 0
type = int
or, to get "whatis" out of the way:
(gdb) maint print type (int_t) 0
...
name 'int'
code 0x8 (TYPE_CODE_INT)
...
This prevents a type printer for "int_t" kicking in, with e.g.:
(gdb) p (int_t) 0
From the manual, we can see that that "whatis (int_t) 0" command
invocation should have printed "type = int_t":
If @var{arg} is a variable or an expression, @code{whatis} prints its
literal type as it is used in the source code. If the type was
defined using a @code{typedef}, @code{whatis} will @emph{not} print
the data type underlying the @code{typedef}.
(...)
If @var{arg} is a type name that was defined using @code{typedef},
@code{whatis} @dfn{unrolls} only one level of that @code{typedef}.
That one-level stripping is currently done here, in
gdb/eval.c:evaluate_subexp_standard, handling OP_TYPE:
...
else if (noside == EVAL_AVOID_SIDE_EFFECTS)
{
struct type *type = exp->elts[pc + 1].type;
/* If this is a typedef, then find its immediate target. We
use check_typedef to resolve stubs, but we ignore its
result because we do not want to dig past all
typedefs. */
check_typedef (type);
if (TYPE_CODE (type) == TYPE_CODE_TYPEDEF)
type = TYPE_TARGET_TYPE (type);
return allocate_value (type);
}
However, this stripping is reachable in both:
#1 - (gdb) whatis (int_t)0 # ARG is an expression with a cast to
# typedef type.
#2 - (gdb) whatis int_t # ARG is a type name.
while only case #2 should strip the typedef. Removing that code from
evaluate_subexp_standard is part of the fix. Instead, we make the
"whatis" command implementation itself strip one level of typedefs
when the command argument is a type name.
We then run into another problem, also fixed by this commit:
value_cast always drops any typedefs of the destination type.
With all that fixed, "whatis (int_t) 0" now works as expected:
(gdb) whatis int_t
type = int
(gdb) whatis (int_t)0
type = int_t
value_cast has many different exit/convertion paths, for handling many
different kinds of casts/conversions, and most of them had to be
tweaked to construct the value of the right "to" type. The new tests
try to exercise most of it, by trying castin of many different
combinations of types. With:
$ make check TESTS="*/whatis-ptype*.exp */gnu_vector.exp */dfp-test.exp"
... due to combinatorial explosion, the testsuite results for the
tests above alone grow like:
- # of expected passes 246
+ # of expected passes 3811
You'll note that the tests exposed one GCC buglet, filed here:

In almost all contexts (except for overload resolution rules and expression
semantics), lvalue and rvalue references are equivalent. That means that in all
but these cases we can replace a TYPE_CODE_REF check to a TYPE_IS_REFERENCE
check and, for switch statements, add a case label for a rvalue reference type
next to a case label for an lvalue reference type. This patch does exactly
that.

This patch makes parse_expression and friends return a unique_ptr
instead of raw pointer [1]:
typedef gdb::unique_malloc_ptr<expression> expression_up;
and then adjusts the codebase throughout to stop using cleanups to
manage lifetime of expression pointers.
Whenever I found a structure owning an expression pointer, I made it
store a unique_ptr instead of a raw pointer, which then requires using
new/delete of the holding structure, instead of XNEW/xfree.
[1] - I'd like to set the rule that types named with an "_up" suffix
are unique_ptr typedefs.
Note I used gdb::unique_xmalloc_ptr instead of gdb::unique_ptr, simply
because we still use xmalloc instead of new to allocate expression
objects. Once that's changed, all we need to do is change the
expression_up typedef and the smart pointer will then call delete
instead of xfree.

GDB computes structure byte offsets using a 32 bit integer. And,
first it computes the offset in bits and then converts to bytes. The
result is that any offset that if 512K bytes or larger overflows.

Assume that we have a C program like this:
struct foo_type
{
int var;
} foo;
struct foo_type *foo_ptr = &foo;
int
main ()
{
return foo_ptr->var;
}
Then GDB should be able to evaluate the following, however, it currently
does not:
(gdb) start
...
(gdb) whatis &(foo_ptr->var)
Attempt to take address of value not located in memory.
The problem is that in EVAL_AVOID_SIDE_EFFECTS mode,
eval.c:evaluate_subexp_standard always returns a not_lval value as the
result for a STRUCTOP_PTR operation. As a consequence, the rest of
the code believes that one cannot take the address of the returned
value.
This patch fixes STRUCTOP_PTR handling so that the VALUE_LVAL
attribute for the returned value is properly initialized. After this
change, the above session becomes:
(gdb) start
...
(gdb) whatis &(foo_ptr->var)
type = int *
This commit is largely the same as commit 2520f728b710 (Forward
VALUE_LVAL when avoiding side effects for STRUCTOP_STRUCT) but applied
to STRUCTOP_PTR rather than STRUCTOP_STRUCT. Both of these commits are
building on top of commit ac1ca910d74d (Fixes for PR exp/15364).

* eval.c (evaluate_subexp_standard): If EVAL_AVOID_SIDE_EFFECTS

This patch adds support for TYPE_CODE_ENUM values to be supplied
as right-hand side operand of the BINOP_REPEAT (@) operator. The
following should now work:
enum {
sz = 17
};
int
main ()
{
int arr[sz + 1] = { 0 };
return 0; /* line 9 here */
}
(gdb) b 9
(gdb) r
(gdb) p arr@sz
$1 = {0 <repeats 17 times>}
(gdb)
A couple of tests is also included in this patch to demonstrate that it is
working as intended.

Assume foo_array is a pointer to a C structure. GDB must evaluate the
following expression properly, but it does not currently:
(gdb) print 1 && &foo_array[1].a
Attempt to take address of value not located in memory.

eval.c:evaluate_subexp_standard always returns a not_lval value as the
result for a STRUCTOP_STRUCT operation. As a consequence, the rest of

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.

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.

As Pedro suggested on gdb-patches@ (see
https://sourceware.org/ml/gdb-patches/2015-05/msg00714.html), this
change makes symbol lookup functions return a structure that includes
both the symbol found and the block in which it was found. This makes
it possible to get rid of the block_found global variable and thus makes
block hunting explicit.

This is a patch I extracted from Pedro's C++ branch. It contains the
most trivial enum fixes, where an integer type/value was used instead
of the appropriate enum type/value. It fixes many C++ errors, since
in C++ you can't mix integers and enums implicitely.
Regardless of the C++ conversion, I think this is a good cleanup to make
use of the appropriate enum types.
Regression-tested on native x86_64.

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.

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++.

A recent change to eval.c triggered a GCC bug that causes a false positive
"may be used uninitialized" warning in evaluate_subexp_standard. This seems
to be triggered by a specific CFG constructed via setjmp and gotos.
While the GCC bug is in the process of being fixed, there are released
compiler versions (in particular GCC 4.9) in the field that show this
problem. In order to allow compiling GDB with one of those compilers,
this commit slightly reworks the CFG (in an equivalent way) of the
affected function, so that the GCC bug is no longer triggered.

BINOP_RANGE was added by the following commit for chill language.
commit badefd2800f5ee2dc6a0eef870771af9dc29bba7
Author: Per Bothner <per@bothner.com>
Date: Wed Nov 29 22:59:31 1995 +0000
* expression.h (enum exp_opcode): Add BINOP_RANGE.
* expprint.c (dump_expression): Support BINOP_RANGE.
* eval.c (evaluate_subexp_standard): Handle BINOP_RANGE (as error).
(case MULTI_SUBSCRIPT): Fix broken f77 value->int ad hoc conversion.
* ch-lang.c (chill_op_print_tab): Support BINOP_RANGE.
(evaluate_subexp_chill): Error on BINOP_COMMA.
Chill language is no longer supported, so we can remove BINOP_RANGE too.
This patch is to remove BINOP_RANGE.

Return void. The list of matching source methods is returned in
"fn_list" and a vector of matching debug method workers is
returned in "xm_worker_vec". Update all callers.
(value_find_oload_method_list): Likewise.
(find_oload_champ): Add "xm_worker_vec" parameter. If it is
non-NULL, then the index of the best matching method in this

The c99 standard in "6.5.3.4 The sizeof operator" states:
If the type of the operand is a variable length array type, the operand
is evaluated;[...]
This patch mirrors the following c99 semantic in gdb:
1| int vla[n][m];
2| int i = 1;
3| sizeof(vla[i++][0]); // No sideffect
4| assert (i == 1);
5| sizeof(vla[i++]); // With sideffect
6| assert (i == 2);
Note: ptype/whatis still do not allow any sideeffects.
This patch was motivated by:
https://sourceware.org/ml/gdb-patches/2014-01/msg00732.html
gdb/ChangeLog:
* eval.c (evaluate_subexp_for_sizeof): Add enum noside argument.
(evaluate_subexp_standard): Pass noside argument.
(evaluate_subexp_for_sizeof) <BINOP_SUBSCRIPT>: Handle subscript case
if noside equals EVAL_NORMAL. If the subscript yields a vla type
re-evaluate subscript operation with EVAL_NORMAL to enable sideffects.
* gdbtypes.c (resolve_dynamic_bounds): Mark bound as evaluated.
* gdbtypes.h (enum range_flags): Add RANGE_EVALUATED case.

This patch enables the sizeof operator for indirections:
1| void foo (size_t n) {
2| int vla[n];
3| int *vla_ptr = &vla;
4| }
(gdb) p sizeof(*vla_ptr)
yields sizeof (size_t) * n.
gdb/ChangeLog:
* eval.c (evaluate_subexp_for_sizeof) <UNOP_IND>: Create an indirect
value and retrieve the dynamic type size.
|
|
In C99 the sizeof operator computes the size of a variable length array
at runtime (6.5.3.4 The sizeof operator). This patch reflects the semantic
change in the debugger.
We now are able to get the size of a vla:
1| void foo (size_t n) {
2| int vla[n];
3| }
(gdb) p sizeof(vla)
yields N * sizeof(int).
gdb/ChangeLog:
* eval.c (evaluate_subexp_for_sizeof) <OP_VAR_VALUE>: If the type
passed to sizeof is dynamic evaluate the argument to compute the length.

This patch enables the sizeof operator for indirections:
1| void foo (size_t n) {
2| int vla[n];
3| int *vla_ptr = &vla;
4| }
(gdb) p sizeof(*vla_ptr)
yields sizeof (size_t) * n.
* eval.c (evaluate_subexp_for_sizeof) <UNOP_IND>: Create an indirect
value and retrieve the dynamic type size.
|
|
In C99 the sizeof operator computes the size of a variable length array
at runtime (6.5.3.4 The sizeof operator). This patch reflects the semantic
change in the debugger.
We now are able to get the size of a vla:
1| void foo (size_t n) {
2| int vla[n];
3| }
(gdb) p sizeof(vla)
yields N * sizeof(int).
* eval.c (evaluate_subexp_for_sizeof) <OP_VAR_VALUE>: If the type
passed to sizeof is dynamic evaluate the argument to compute the length.

This patch changes a few minimal symbol lookup functions to return a
bound_minimal_symbol rather than a pointer to the minsym. This change
helps prepare gdb for computing a minimal symbol's address at the
point of use.
Note that this changes even those functions that ostensibly search a
single objfile. That was necessary because, in fact, those functions
can search an objfile and its separate debug objfiles; and it is
important for the caller to know in which objfile the minimal symbol
was actually found.
The bulk of this patch is mechanical.
