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
* Changed to use default constructor for Tokens
* Switched to using default constructor for Tokens
* Switched to using default constructor for Token
* Added new test for deleting front Token
Also made sure to use the correct constructor for Token in other tests.
* Syntax error
* Replaced tokensFront and tokensBack with a struct
This decreases the size of the Token class for performance purposes.
* Replaced tokensFront and tokensBack with a struct
* Added tokensFrontBack to destructor
* Reworked to use TokensBackFront struct
Also ran astyle.
* Reworked to use TokenList's TokensFrontBack member
* Reworked to use TokensFrontBack struct
* Reworked to use TokensFrontBack struct
* Reworked to work with TokensFrontBack struct
* 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
Removed default constructor and replaced it with a single-argument constructor with a default value.
* Fixing stylistic nits

templated member function (and probably any nested template), the
tokenizer would recognise it as a syntax error, assuming that return
type *must* come after a template<> token.

posix.cfg: access(): Removed redundant configuration, added tests ( #1048 )
...
I intentionally removed the second access() configuraion because it was
missing the use-retval attribute. But calling access() without using the
return value is absolutely senseless.
I added tests to posix.c to verify the correct configuration of
access().

Fix #7504 : posix: open() was twice in configuration file ( #1032 )
...
* Fix #7504 : posix: open() was twice in configuration file
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.
* posix.cfg: open(): Add TODO for use-retval configuration

Add support for simple c++ 11 type ailases like: using INT = int; ( #1024 )
...
* Add support for simple c++ 11 type ailases like: using INT = int;
Only types supported by ValueType are supported. Complex types like
function pointers are not supported. Template type aliases are not
supported.
* Fix crash when type in using type alias is simplified away.
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
new type is different from the platform type.
