Valueflow: Fix right shift with more than 31 bits ( #1553 )
...
When comparing if the shift is large enough to make the result zero, use
an unsigned long long to make sure the result fits. Also, a check that
avoids setting the value if the shift is equal to or larger than the
number of bits in the operand (this is undefined behaviour). Finally,
add a check to make sure the calculated value is not too large to store.
Add test cases to cover this.
This was detected by an MSVC warning.

converted to 64 bits (was 64-bit shift intended?)

Fix issue 8910: Regression: ValueFlow: wrong conditional tokvalue
...
This fixes issue in:
```cpp
void f()
{
char stack[512];
RGNDATA *data;
if (data_size > sizeof (stack))
data = malloc (data_size);
else
data = (RGNDATA *)stack;
if ((char *)data != stack)
free (data); // <- data is not stack
}
```
It seems the `ProgramMemory` can't handle two known values(such as int and tok) together. So instead `ValueFlowAfterAssign` runs `ValueFlowForward` with tok values and then runs it with the other values.

Print test case name in assert
...
I sometimes find myself wondering which test cases I have broken when I fiddle with some check (since I then can try running these specific tests in the debugger, or make a small change and see if the tests pass). This PR adds the testclass and the test case names to the file and line number. I took special care to cover the case where an assert would be placed directly in the ```run()```-function, i.e., not inside a test case (from what I could see, no such case exists). If there is no need to handle this case, the code can be simplified (there wouldn't be need for the ```teardownTest()```-function for example).
The exact format for how to print the test name is very much up for discussion.

So this unifies the `valueFlowAfterCondition` so it re-uses more code between checking for integers and container sizes. This should make valueFlowContainer more robust.
It also extends valueflow to support container comparisons such as `if (v.size() < 3)` or `if (v.size() > 3)` using the same mechanism that is used for integers.

Add check for return value of boolean function ( #1451 )
...
* Add check for return value of boolean function
The rule for converting an integer to a boolean is that 0 is mapped to
false and everything else is mapped to true. There is nothing wrong with
the following code (according to the standards):
bool f()
{
return -1;
}
and neither gcc nor clang will warn about it. However, it's a bit
confusing. This commit adds a check that warns when a value other than 0
or 1 is returned from a boolean function (similar to the existing check
that functions with boolean arguments are only passed 0 or 1). Since the
code is perfectly legal, set the severity to "Style".
* Use early continue and remove some braces
* Add testcase with multiple returns
* Avoid null pointer dereference in case of return without operand

* #4241 : Check for address of single character passed as string
Add a check that address of a single character is not passed as argument
to argument marked as strings (using strz). The check does not warn if
the address of a character with known value '\0'.
Since ValueFlow currently does not handle global constants (see #7597 ),
do not warn if the variable is global to avoid FPs when the address of
a global variable assigned to '\0' is passed to a function expecting a
string.
Remove comment in docs saying strz is unused.

Fixed #8693 (Template specialization: Constructor detected as normal … ( #1418 )
...
* Fixed #8693 (Template specialization: Constructor detected as normal function (functionStatic error))
Refactor template simplifier to remove the existing full specialization
function expandSpecialized and allow full specializations to use the
existing function expandTemplate. The function expandTemplate was
modified to either expand the template like it originally did by copying
it or to modify the template in place. Both instantiated and
uninstantiated full specializations are modified in place. This also
fixes #8692 and probably other related tickets as well.
The function simplifyTemplates now tries twice to simplify templates so
more templates can be simplified. We should try as many times as
necessary to find all possible templates. We can't do that now because
uninstantiated templates are left unchanged. It is relatively straight
forward to have the new code also expand in place uninstantiated
templates with their symbolic types but namespaces are not handled
properly (ticket #8671 ) and it would introduce regressions.
* Fix travis warnings.

Fix #8230 : FP unknown evaluation order on comma expression in while clause ( #1415 )
...
The while part of a do-while loop looks almost like a function call, so
extend the check for function calls to ignore while-statements.
Note that there was only an FP when checking c-code, since the check is
disabled for c++-code. Therefore, make sure the test cases are run on a
c-file.

isVariableDeclaration: Handle pointer to const pointer ( #1395 )

isVariableDeclaration did not handle pointer to const pointer, or
pointer to volatile pointer. This resulted in FPs in examples like the
following:
class Fred {
public:
const char *const *data;
const char *const *getData() { return data; };
}
where cppcheck would say getData could be static, since it didn't
recognize const char *const *data as a variable declaration.

Support floats in valid config ( #1297 )
...
* Add tests for invalid ranges
* Refactor loadLibErrors
This reduces the amount of code slightly and will simplify adding
more tests.
* Handle empty valid field
Before this change, the sequence <valid></valid> in a config file would
result in a segmentation fault. Now an empty field results in the error
message:
cppcheck: Failed to load library configuration file 'mycfg.cfg'. Bad attribute value '""'
* Add support for valid for floating point arguments
Previously, it was not possible to add valid ranges to floating point
arguments since it only handled integers. This made ranges not work well
for floating point arguments since arguments were cast to integers
before the ranges were handled.
Fix this by using doubles instead of integers if the argument is a float.
Add some tests for this and make sure errors are printed with enough
precision (somewhat arbitrarily chosen).
Note that it is still only possible to add integer ranges (i.e. -1:1).
* Add support for floats in configuration valid range
Now that it is possible to handle decimal arguments, there is no reason
to not allow non-integer ranges. Take care to not allow broken
configurations.
* Move check to within if-clause
* Move asin{,f,l} and acos{,f,l} input checks to config file

Fix crash bug #8579 ( #1238 )
...
* Added declaration for deletePrevious function
* Added definition for deletePrevious function
* Fixed crash from deleteThis invalidating pointers
The crash was caused by deleteThis() invalidating the pointer to a constant variable usage. This happened when a usage followed an assignment. This fixes bug #8579 .
* Added tokensFront to match tokensBack
This means deletePrevious can set the list's front if necessary.
* Initialised tokensFront in appropriate places
* Switched to using default Token constructor
* Switched to using Token default constructor
* Switched to using default constructor for Token
* Added missing argument to Token constructor

* Added new test for deleting front Token

* Syntax error
* Replaced tokensFront and tokensBack with a struct

* Replaced tokensFront and tokensBack with a struct
* Added tokensFrontBack to destructor

* Removed unnecessary scope operator
* Added missing parentheses
* Fixed syntax error
* Removed unnecessary constructor
* Default constructor now 0-initialises everything
This is safer for not using a temporary TokensFrontBack object, and doesn't use delegating constructors which aren't supported yet.
* Fixed unsafe null check
* Added missing explicit keyword
* Fixing stylistic nits
Removed default constructor as it has been superseded by the single-argument constructor with a default argument value.
Renamed listEnds to tokensFrontBack.
Fixed if statement that was supposed to be adding safety but would actually cause a crash if tokensFrontBack was null.
* Fixing stylistic nits

(currently a useful configuration is not really possible, see ticket 8329) the
check-library message is suppressed.

tokenizer would recognise it as a syntax error, assuming that return
type *must* come after a template<> token.

This fixes ticket #7504 : Problems with the open function were not always
detected because the open function was twice in posix.cfg and only the
second configuration was used by cppcheck. Like suggested now only
one configuration is used and the third parameter has a default value
and is thereby optional.
use-retval has been removed to avoid duplicate warnings because the
alloc/dealloc configuration already warns about unused retval.
According tests to verify that open is configured
correctly now have been added to test/cfg/posix.c.

This fixes a crash when size_t is replaced with unsigned long in: using
size_t = unsigned long; by the tokenizer.
This does not fix the problem where Tokenizer::simplifyPlatformTypes()
simplifies away size_t in other cases. This is only a problem when the

Set struct size cutoff in passedByValue check to 2*sizeof_pointer
...
Struct arguments are either pushed to the stack or passed in the
registers. Since both methods operate on machine words it is logical to
tie the maximum size of a struct argument that doesn't trigger
passedByValue diagnostic to the size of the machine word.
Also guessed size of STL classes is set to 3*sizeof_pointer, this better
represents reality and ensures that structs containing them will still
trigger passedByValue.

Add internal check that checks for redundant non-nullness checks in Token::(simple)Match checks.
...
In code like
if (tok && Token::simpleMatch(tok, "bla")) {}
or
if (tok->previous() && Token::Match(tok->previous(), "foo")) {},
the first check is redundant because Token::(simple)Match already checks if the argument token is null.
