misra: Add support for expected suppressions in header files in -verify mode (#3252) 
This commit allows to specify expected suppressions in the included
header files. This is necessary to verify MISRA checkers, which make
requirements for header files. For example, Rule 8.2 requires adding
prototypes for each function to the header files.

misra: Fixed a crash in rule 8.2 (#3208) 
Due to incorrect indentation, we return "None" instead of an empty list,
which causes the crash.

The problem was reported on the forum: https://sourceforge.net/p/cppcheck/discussion/general/thread/e146b8d779/

22727ee3ab Addons; split up possible/known values and impossible values. This is inconsistent with core Cppcheck, however the addons do not handle impossible values in general. A future improvement might be to clarify this somehow, maybe renaming Token.values. 2021-02-23 22:40:49 +01:00

cppcheckdata: Use instance attributes in Cppcheckdata (#3029) 
This commit makes CppcheckData class to use instance attributes instead
of class attributes.

Since class attributes are mutable (list), when you append to them, they
don't promote to instance variable which means when you call parsedump()
multiple times data just gets appended to them.

misra.py: Treat enum constants as constant known at compile time (#2823) 
C89 standard defines enum members as enumeration contants at ch.
6.4.4.3, and they are always known at compile time.

This commit fix false positives for rule 18.8 (and possible other rules
that check "constentess") with enumeration members.

misra.py: Fix 12.3 FP for variables defined in headers (#2773) 
When we include the header file with variables definitions, Cppcheck
will write `variables` entries with line numbers from the header to the
dump file.

If the line number in the header file and the source file are equal,
misra.py performs an additional check what leads to false positives.

Minimal example that demonstrates the problem:

`misra_fp.c`:
```c
void test_12_3_fp(void)
{
    //Initialize the events queue
    QEQueue_init(&me->deferred_event_queue, me->deferred_events_queue_buf, Q_DIM(me->deferred_events_queue_buf));
}
```

`misra_fp.h`:
```c

static const uint32_t timer_max_blocking_call_us;
```

This commit closes trac ticket 9874.
