I broke the build with --disable-analyzer with
g:66dde7bc64b75d4a338266333c9c490b12d49825, due to:
../../src/gcc/analyzer/analyzer-pass.cc: In member function ‘virtual unsigned int {anonymous}::pass_analyzer::execute(function*)’:
../../src/gcc/analyzer/analyzer-pass.cc:86:3: error: ‘sorry_no_analyzer’ was not declared in this scope
86 | sorry_no_analyzer ();
| ^~~~~~~~~~~~~~~~~
Fixed by including the relevant header file.
Sorry about the breakage.

* analyzer-pass.cc: Include "analyzer/analyzer.h" for the
declaration of sorry_no_analyzer; include "tree.h" and
"function.h" as these are needed by it.

The overflow checks done in growslice always reported an error for the
capacity argument, even if it was the length argument that overflowed.
This change lets the code pass the current issue4085b.go test.

This patch adds a new GCC plugin event: PLUGIN_ANALYZER_INIT, called
when -fanalyzer is starting, allowing for GCC plugins to register
additional state-machine-based checks within -fanalyzer. The idea
is that 3rd-party code might want to add domain-specific checks for
its own APIs - with the caveat that the analyzer is itself still
rather experimental.
As an example, the patch adds a proof-of-concept plugin to the testsuite
for checking CPython code: verifying that code that relinquishes
CPython's global interpreter lock doesn't attempt to do anything with
PyObjects in the sections where the lock isn't held. It also adds a
warning about nested releases of the lock, which is forbidden.
For example:
demo.c: In function 'foo':
demo.c:11:3: warning: use of PyObject '*(obj)' without the GIL
11 | Py_INCREF (obj);
| ^~~~~~~~~
'test': events 1-3
|
| 15 | void test (PyObject *obj)
| | ^~~~
| | |
| | (1) entry to 'test'
| 16 | {
| 17 | Py_BEGIN_ALLOW_THREADS
| | ~~~~~~~~~~~~~~~~~~~~~~
| | |
| | (2) releasing the GIL here
| 18 | foo (obj);
| | ~~~~~~~~~
| | |
| | (3) calling 'foo' from 'test'
|
+--> 'foo': events 4-5
|
| 9 | foo (PyObject *obj)
| | ^~~
| | |
| | (4) entry to 'foo'
| 10 | {
| 11 | Py_INCREF (obj);
| | ~~~~~~~~~
| | |
| | (5) PyObject '*(obj)' used here without the GIL
|
Doing so requires adding some logic for ignoring macro expansions in
analyzer diagnostics, since the insides of Py_INCREF and
Py_BEGIN_ALLOW_THREADS are not of interest to the user for these cases.

When diffing test results, there sometimes occur spurious "New tests

The reason is that if create_gcov is not installed, then the cached

test.

dse.c:find_shift_sequence tries to represent a store and load
back as a shift right followed by a truncation. It therefore
needs to find an integer mode in which to do the shift right.
The loop it uses has the form:
FOR_EACH_MODE_FROM (new_mode_iter,
smallest_int_mode_for_size (GET_MODE_BITSIZE (read_mode)))
which implicitly assumes that read_mode has an equivalent integer mode.
As shown in the testcase, not all modes have such an integer mode.
This patch just makes the code start from the smallest integer mode and
skip modes that are too small. The loop already breaks at the first
mode wider than word_mode.

Options: -fopenmp and -fopenacc imply concurrent calls to a
procedure; now also -fopenacc implies -frecursive, disabling
that larger local const-size array variables use static memory.
Run-time recursion check: Always reset the check variable at the
end of the procedure; this avoids a bogus error with -fopenmp
when called twice nonconcurrently/nonrecursively. (Issue requires
using -fno-automatic or -fmax-stack-var-size= to trigger.)

(Build_DIC_Procedure_Body): Call Add_Parent_DICs to generate
checks for DICs associated with any parent types, implementing
the required "additive" semantics for DICs. When building a DIC
procedure body for a partial view (when Partial_DIC is True),
call Add_Own_DIC when the type has its own DIC. In the case of
"full" DIC procedures, a call is generated to any partial DIC
procedure of the type (unless the procedure has a null body),
along with checks for any DICs inherited by the full view.
(Build_DIC_Procedure_Declaration): Add handling for partial DIC

(Add_Inherited_Tagged_DIC): Remove the formals Par_Typ,
Deriv_Typ, and Obj_Id, and add formal Expr, which denotes DIC's

(Add_Inherited_DICs): New procedure to locate a DIC pragma
associated with a parent type, replace its references
appropriately (such as any current instance references), and add
a check for the DIC.
(Add_Own_DIC): Add an Obj_Id formal to allow caller to pass the
_init formal of the generated DIC procedure.
(Add_Parent_DICs): New procedure to traverse a type's parents,
looking for DICs associated with those and calling
Add_Inherited_DICs to apply the appropriate DIC checks.
(Is_Verifiable_DIC_Pragma): Treat pragmas that have an Empty
first argument the same as a pragma without any arguments
(returning False for that case).
* exp_ch3.adb (Init_One_Dimension): Generate calls to the

(Build_Array_Init_Proc): The presence of a DIC on the component
type is an additional condition for generating an init proc for
an array type.
(Build_Init_Statements): When the record component's type has a
DIC, and the component declaration does not have an
initialization expression, generate a call to the component
type's DIC procedure.
(Expand_N_Object_Declaration): Modify the call to Build_DIC_Call
to pass a new occurrence of the object's defining id rather than
the id itself.
(Freeze_Type): Only build a type's DIC procedure (if it has one)
for types that are not interfaces.
* exp_spark.adb (Expand_SPARK_N_Freeze_Type): Remove From_Freeze
actual and add a ??? comment.
(Expand_SPARK_N_Object_Declaration): Modify call to
Build_DIC_Call to pass a new occurrence of the object id rather

* sem_aggr.adb (Resolve_Record_Aggregate): Declare local flag
Is_Box_Init_By_Default and set it in cases where the component
association has a box and the component is being initialized by
default (as opposed to initialized by an initialization
expression associated with the component's declaration).
(Add_Association): If the association has a box for a component
initialized by default, the flag
Was_Default_Init_Box_Association is set on the new component
association (for later testing during expansion).
(Get_Value): Reset Is_Box_Init_By_Default to False.
* sem_ch3.adb (Build_Assertion_Bodies_For_Type): Rearrange code
