orbitcowboy e47b6bf862 Revert quick fix: 0ace50204b (comments) 2019-04-09 08:38:08 +02:00
orbitcowboy 0ace50204b Fixed a crash on garbage code. The test input was found by afl_cppcheck (type2). Unforunately, the cppcheck-fuzzer-client was crashing only when executing the binary input from afl-fuzz. Using the translated-input (C-code) did not lead to crash. I tested it with activated address/undefined behaviour sanitizer as well as non-instrumented source code. Since the translated output is too long (164 lines), i will not add it the testgarbage.cpp. 2019-04-07 13:27:33 +02:00

Paul Fultz II 4e147a4c59 Add a check for duplicate if statements
This will warn for this:

```cpp
int f(int val)
{
	int i = 0;
	if( val & 0xff)
		i = 1;
	if( val & 0xff)
		i = 1;
        return i;
}
```

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
}
```
