Daniel Marjamäki bc34f0239d Disable the subfunction value flow analysis. It does not work well and needs to be rewritten. There are false positives. 2018-12-18 14:36:49 +01:00

Paul Fultz II 34330b51d1 Fix issue 8905: Condition 'a==0' is always false

Paul Fultz II 025881cf35 Fix issue 8829: Condition '...' is always true (int buf[42]; if(buf != NULL){})
This makes arrays non-null in valueflow, so it can catch comparisons against null that is always true:

```cpp
void f(void) {
   int buf[42];
   if( buf != 0) {;} // << always true
}
```

Paul Fultz II 9b973e652c Issue 8830: New check: Function argument evaluates to constant value
Add a check for function arguments that can be constant:

```cpp
extern void bar(int);
void f(int x) {
   bar((x & 0x01) >> 7); // function 'bar' is always called with a '0'-argument
}
```

Paul Fultz II 45dcfad9f9 Fix issue 8899: False positive returnDanglingLifetime when returning by value
This fixes the FP from:

```cpp

        public:
        MyString(char* source)
        {
                length = strlen( source );
                buffer = new char[length+1];
                if( buffer )
                {
                        strcpy( buffer, source );
                }
        }

        char* buffer;
        int length;
};

MyString Foo()

        printf(str.buffer);
}
