Ken-Patrick LEHRMANN a923115710 Add missing operators <<= and >>=
This fixes issues (at least false positives) in code using them.
For instance:

```
unsigned compute(unsigned long long a) {
    unsigned num = 0;
    while (a > 0xFFFFFFFF) {
      a >>= 32;
      num += 32;
    }
    if (a > 0xFFFF) {
      a >>= 16;
      num += 16;
    }
    if (a > 0xFF) {
      num += 8;
    }
    return num;
}
```

would give false positive:
```
cppcheck --enable=style  sl3.cpp
Checking sl3.cpp ...
sl3.cpp:11:11: style: Condition 'a>0xFF' is always false [knownConditionTrueFalse]
    if (a > 0xFF) {
          ^
sl3.cpp:3:14: note: Assuming that condition 'a>0xFFFFFFFF' is not redundant
    while (a > 0xFFFFFFFF) {
             ^
sl3.cpp:11:11: note: Condition 'a>0xFF' is always false
    if (a > 0xFF) {
          ^

Ken-Patrick Lehrmann 61ccf888b3 Fix some false positives when the same expression at different places does not have the same value
Typically with
```
int F(int *f);
void F2(int *a, int *b) {
  int c = *a;
  F(a); // modifies *a
  if (b && c != *a) {}
}
```
we would get the following FP:
```
[test.cpp:3] -> [test.cpp:5]: (style) The comparison 'c != *a' is always false because 'c' and '*a' represent the same value.\n
```

I guess it boils down to isSameExpression only checking that the
expression is the same (in the above case, "*a" and "*a" are indeed the
same), but there's not real check on the values.
So the patch here is a bit hackish, and we still have false negatives in
cases with dereferenced pointers.

2020-07-08 15:10:41 +02:00
Rikard Falkeborn 4996ec190e Fix #9652 (fp memleak with function call with cast)
When the first argument was (void *)(1), at the start of the second
iteration, arg was pointing to the "1", which caused problems for
nextArgument(), which saw the ")" as the next token and returned
nullptr, signalling that there are no more arguments.

Instead, save the first token in the argument, which makes
nextArgument() do the right thing.

Ken-Patrick Lehrmann 5a3789a23f 9769: Improve value flow for ternary operator
In some cases, the condition of the ternary operator is assigned a known

take the opportunity to assign a value to the ternary operator (and to
the other parents in the ast).
This patch adds this capability.

9768: Fix ast with throw in the middle of return (#2678)
* 9768: Fix ast with throw in the middle of return

```
int f(bool x)
{
    return x ? 0 : throw 0;
}
```

The `throw` part was not included in the ast, leading to an invalid
ternary operator.

* 8526: Fix ast construction for ternary operator

This tries to decide a bit more properly when ':' can be part of a
ternary operator. More precisely, there are some times when we want to
delay the construction of the ast for ':', so that it is place
accordingly to the matching '?'.

Typically, this fixes an issue with
`return val < 0 ? throw 1 : val;`,
where the ast for ':' would be constructed during as part of the
`throw`, and the ast for `?` would be invalid.

This patch is a bit of a hardcode, stating that we don't expect ':'
inside a throw, unless there is a complete ternary operator in there
(there can't be a range based for loop, a case in a switch). When we
reach ':', we know we are and the end of the `throw`.

"void", then later "void" is removed and we have an internal error.

Fix some false positive in loop forward analysis (#2669)
* Fix some false positive in loop forward analysis

In cases like:
```
bool b();
void f()
{
    int val[50];
    int i, sum=0;
    for (i = 1; b() && i < 50; i++)
        sum += val[i];
    for (; i < 50; i++)
        sum -= val[i];
}
```
The forward analysis assumed the second loop was entered, and we ended
up with false positive in it:
 `Array 'val[50]' accessed at index 50, which is out of bounds`

* Fix style

gtk.cfg: Fix syntax errors and false positives (#2552)
A missing definition for g_assert_cmp*() causes syntax errors if code
like g_assert_cmpint(a, ==, b); is encountered.
The function g_hash_table_iter_replace() does not have to be marked
with leak-ignore since the memory could be freed later if corresponding
functions are present in the GHashTable. Since we can not know if this
is the case we have to assume that the memory is freed to avoid false
positives. The same is true for g_hash_table_insert() and
g_hash_table_replace().
