misra: Fix 8.2 false positives ( #3309 )
...
* misra: Fix 8.2 false positives
Fix false positives in rule 8.2 that occurred in cases when we have a
function definition and declaration in the same file.
For example, the following code generated false positives before this
commit:
```
void f(uint8_t * const x);
void f(uint8_t * const x)
{ (void)x; }
```
We need to distinguish the declaration and the definition, so the dump
file generation routine was extended to keep token where the definition
of the function. The analysis in the addon also been improved.

Improve support for labels in simplifyAddBraces step ( #3278 )
...
Previously only a single regular label before a compound statement was
allowed in simplifyAddBracesPair() after if/switch/do/while/for.
This patch adds support for:
* case-labels;
* labels before a single statement;
* labels before try/catch blocks;
* multiple consecutive labels.
Additionally the code for skipping a case label was extracted into a
separate function from simplifyLabelsCaseDefault() and reused in
simplifyAddBracesPair().

Fix AST for brace initialization after decltype() ( #3245 )
...
Currently sub-expressions like decltype(x){} break AST creation for
subsequent tokens in the whole expression. In some cases this triggers
validation checks in validateAst() and analysis on the file stops.
For example, code like this:
int x = decltype(0){} ? 0 : 1;
currently produces internalAstError.
To fix the issue iscpp11init_impl() was changed to recognize { preceded
by decltype(expr) as a start of C++11 brace initialization expression.

Remove unnecessary null check ( #3215 )
...
Spotted by coverity (as the condition in the `if` part `isArrayVar(tok)`
dereferences tok.
Tok can't be null here, because the condition in the `else if`on line
268 checks that there is a `%var%` following, and
`tok = Token::findmatch(tok->next(), "%var%");` simply gets this `%var%`
token.

Fix varId assignment for uses of variables declared in the if condition ( #3231 )
...
Variables declared in the if condition (or in C++17 init-statement) are
visible not only in the if body but also in the else body. But logic in
Tokenizer::setVarIdPass1() handled such variables as if they were
declared in the if body.
As the result they were removed from variablesMap by the time the else
block was parsed and their uses in the else block were either given an
incorrect varId from variables in some outer scope or not given a varId
at all.
This then resulted in false positive unreadVariable errors for variables
declared in the if condition (or init-statement) and used only in the
else block.
Simplification from "else if ..." to "else { if ... }" was moved before
setVarId() to simplify detection for ends of blocks in if-else chains.

Read error locations in the correct order from XML ( #3226 )
...
When ErrorMessage::callStack elements are serialized to XML they are
saved in the reverse order. But when they read back from XML they are
added at the end of the list. Thus the round trip via XML reverses the
order of ErrorMessage::callStack.
From the user point of view it looks like the usage of the
--cppcheck-build-dir option sometimes (when the file wasn't reanalyzed,
but that is hard to spot) results in incorrect location info for some
diagnostic messages.
Moreover, when the first location matches some suppression rule and the
last doesn't match any (or vice versa), usage of --cppcheck-build-dir
results in some diagnostic messages appearing and disappearing seemingly
at random (again, depending on whether the file was reanalyzed or not).

Improve handling of realloc in memory leak checker ( #3036 )
...
Mark realloced variables as realloced instead of freed. This allows
improved checking for code with error realloc handling.
If cppcheck finds an if-statement which checks the validity of the
allocated memory or resource, check if the memory/resource is
reallocated from another variable. If so, we can add checking of that
variable in the if-statement instead. This allows to check that variable
for memleaks and double frees.
This fixes #9292 and #9990 which both concern FPs with double frees
after correct error handling.

remove cleanupAfterSimplify from the template simplifier ( #2998 )
...
The template simplifier works well enough now so cleanupAfterSimplify is
no longer necessary. In fact cleanupAfterSimplify was introducing a bug
which improperly simplified C++ style casts.
Bugs should be exposed and fixed properly rather than just hiding them.

fix #9983 (TemplateSimplifier: template not simplified : f(0,0);) ( #2905 )
...
Currently template type deduction for functions only works for single
template argument single function argument functions with a literal
argument.
This patch starts to add support for single template argument multiple
function argument functions. It correctly handles functions with
multiple arguments of the same type. It also handles a mix of template
and non-template arguments.
It does not add support for overloading non-template arguments.
It does not add support for multiple parameter template functions.
It does not add support for type deduction from variable arguments.

Fix #9647 : Set correct enum value ( #2856 )
...
* Tokenize: Set varId for variables in enum
Set varIds in enum values. It was previously disabled in 5119ae84b8Fix #9647 : Value of enums with variables as init values
C++ allows enum values to be set using constexprs, which cppcheck did
not handle before. To solve this, add a new pass to valueflow to update
enum values after global consts have been processed. In order to do so,
I moved all settings of enum values to valueflow. After setting the enum
values, we need another call to valueFlowNumber() to actually set users
of the enums.
There is still room for improvements, since each pass of
valueFlowGlobalConstVar() and valueFlowEnumValue() only sets variables
that are possible to set directly, and not if setting the value of a
variable allows us to set the value of another. For example
constexpr int a = 5;
constexpr int b = a + 5;
enum E { X = a };
constexpr E e = X;
Here both b and e will not have their values set, even though cppcheck
should be possible to figure out their values. That's for another PR
though.
This was tested by running test-my-pr.py with 500 packages. The only
difference was one error message in fairy-stockfish_11.1, where cppcheck
now printed the correct size of an array instead of 2147483648 which I
assume is some kind of default value. In that package, using a constexpr
when setting enum values is common, but as mentioned, there was no
change in the number of warnings.

Symboldatabase: Don't set unknown enum values ( #2852 )
...
Previously, if an enum value was set to a value unknown to cppcheck, the
next enum value would erroneously be set to the last set value plus one
(or zero, if no enum value had been set before). This partially fixes
Trac ticket #9647 , in the sense that it no longer sets wrong values for
these enum values. Further improvements to this would be to set the
correct values instead. It also fixes the false positive mentioned in the
comments in the ticket.

Fix false positives with condition with || and &&
...
The value of something in the middle of a condition with mixed || and &&
gives no information on which branch will be taken.
For instance with:
```
int f(int a, int b, bool x) {\n"
if (a == 1 && (!(b == 2 && x))) {
} else {
if (x) {
}
}
return 0;
}
```
We can enter the if part whether x is true or false, and similarly,
enter the else part whether x is true or false. Same thing with the
value of b.
This fixes the following false positive with above code:
```
:4:13: style: Condition 'x' is always true [knownConditionTrueFalse]
if (x) {
^
:2:33: note: Assuming that condition 'x' is not redundant
if (a == 6 && (!(b == 21 && x))) {
^
