* Check if the tokens are the same
* Report the operator and not the expressions
* added CLion project folder to .gitignore
* adjusted project name in CMakeLists.txt
* avoid warning when compiling "Debug" with Visual Studio via CMake
There was a GCC-style compiler flag in the common flags in compileroptions.cmake which caused the following warning:
cl : Command line warning D9002 : ignoring unknown option '-O0'
* compileroptions.cmake: restored original formatting
* daca2.py: added missing import
* misra.py: removed unnecessary escaping from regular expression
* Fix issue 6856: add checks in isOppositeCond when using == and < or >
* Move tests to testcondition
* Fix some more tests
* Fix test messages
* Remove the float check
* added CLion project folder to .gitignore
* adjusted project name in CMakeLists.txt
* avoid warning when compiling "Debug" with Visual Studio via CMake
There was a GCC-style compiler flag in the common flags in compileroptions.cmake which caused the following warning:
cl : Command line warning D9002 : ignoring unknown option '-O0'
* compileroptions.cmake: restored original formatting
* some small *.py script cleanups
* Add tests for log10{,f,l} valid arguments
* Add log2{,f,l} to checkfunctions
* Add log1p{,f,l} to checkfunctions
* checkfunctions: Simplify check for log function limit out of range
The conditions for negative and non-negative int and float were
identical so the call to isNegative can be removed and the if-statements
be simplified.
* Set values in else branch even when the first branch modifies the value
* Move tests
* Add check for goto
* Remvoe todo
* Also check scope is noreturn
* Use isEscapeScope when variables are changed
* Fix issue 470: Condition is always true or false on logical operators
* Dont warn on literals
* Compute logical operators using valueflow
* Fix FP when using literals
* Always warn on subconditions that are always true
* Use percent matches first
* Add test for logical operators
* Check if parent is null
* added CLion project folder to .gitignore
* adjusted project name in CMakeLists.txt
* avoid warning when compiling "Debug" with Visual Studio via CMake

naming.py is called parallel (4 times at a time) for all *.cpp.dump files directly in gui/ and lib/.
@matthiaskrgr had the idea for it: e46c499f5a (commitcomment-29717495)
Files in gui/test are now ignored already when creating the .dump files.
According to the Travis log output these changes speed up the Travis build up to three minutes.
* 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
Following error occurs when building with MinGW 7.2.0 and Ninja on Windows:
cli/CMakeFiles/cli_objs.dir/filelister.cpp.obj: In function `MyIsDirectory':
cppcheck-1.84\build/../cli/filelister.cpp:49: undefined reference to `__imp_PathIsDirectoryA'
cli/CMakeFiles/cli_objs.dir/filelister.cpp.obj: In function `MyFileExists':
cppcheck-1.84\build/../cli/filelister.cpp:67: undefined reference to `__imp_PathFileExistsA'
collect2.exe: error: ld returned 1 exit status
This is the corresponding code in filelister.cpp:
#ifdef _WIN32
// snip
static BOOL MyIsDirectory(const std::string& path)
{
#ifdef __BORLANDC__
return (GetFileAttributes(path.c_str()) & FILE_ATTRIBUTE_DIRECTORY);
#else
// See http://msdn.microsoft.com/en-us/library/bb773621(VS.85).aspx
return PathIsDirectoryA(path.c_str());
#endif
}
static BOOL MyFileExists(const std::string& path)
{
#ifdef __BORLANDC__
DWORD fa = GetFileAttributes(path.c_str());
BOOL result = FALSE;
if (fa != INVALID_FILE_ATTRIBUTES && !(fa & FILE_ATTRIBUTE_DIRECTORY))
result = TRUE;
#else
const BOOL result = PathFileExistsA(path.c_str());
#endif
return result;
}
The else blocks assume that Shlwapi.lib is available on Windows except with Borland,
so the patch set ensures that the library is linked on the same condition.
