Paul Fultz II d7c20b15e7 Fix FP with const argument when doing a variable and cast (#1649) 2019-02-07 14:59:09 +01:00
rikardfalkeborn 7779a9186e Use valueflow in unsigned less than zero checker (#1630)
The unsigned less than zero checker looked for patterns like "<= 0".
Switching to use valueflow improves the checker in a few aspects.

First, it removes false positives where instead of 0, the code is using
0L, 0U, etc. Instead of having to hard code the different variants of 0,
valueflow handles this automatically. This fixes FPs on the form

	uint32_t value = 0xFUL;
	void f() {
  		if (value < 0u)
		{
			value = 0u;
		}
	}

where 0u was previously not recognized by the checker. This fixes #8836.

Morover, it makes it possible to handle templates properly. In commit
fa076598ad, all warnings inside templates
were made inconclusive, since the checker had no idea if "0" came from
a template parameter or not.

This makes it possible to not warn for the following case which was
reported as a FP in #3233

	template<int n> void foo(unsigned int x) {
	if (x <= n);
	}
	foo<0>();

but give a warning for the following case

	template<int n> void foo(unsigned int x) {
	if (x <= 0);
	}

Previously, both these cases gave inconclusive warnings.

Finally, it makes it possible to give warnings for the following code:

	void f(unsigned x) {
		int y = 0;
		if (x <= y) {}
	}

Also, previously, the checker for unsigned variables larger than 0, the
checker used the string of the astoperand. This meant that for code like
the following:

	void f(unsigned x, unsigned y) {
		if (x -y >= 0) {}
	}

cppcheck would output

	[unsigned-expression-positive.c] (style) Unsigned variable '-' can't be negative so it is unnecessary to test it.

using expressionString() instead gives a better error message

        [unsigned-expression-positive.c] (style) Unsigned expression 'x-z' can't be negative so it is unnecessary to test it.

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
}

rikardfalkeborn 75caf8e4de 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.

Stas Cymbalov ff38cc5c13 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.
