#11134 Fix broken AST with (designated) initializers (#4550) 
* Make control flow a bit easier, and more similar to previous code

Made similar to around line 790

* In a cpp11init, always parse only the corresponding } (#11134)

- _always_, because in some cases this was omitted (around line 790) or too strict (around line 860)
- _only_, and not following tokens which happen to be } as well (around line 1030)

* Fix unit tests: AST was incorrect, now is fixed

auto var{ {{},{}}, {} };

Old AST:
```
{
|-var
`-{
  `-,
    |-,
    | |-{
    | `-{
    `-{
```
New AST:
```
{
|-var
`-,
  |-{
  | `-,
  | | |-{
  | | `-{
  `-{
```
Compare the same example, but with `X{}` instead of just `{}`:
`auto var{ a{b{},c{}}, d{} };`
```
{
|-var
`-,
  |-{
  | |-a
  | `-,
  | | |-{
  | | | `-b
  | | `-{
  | | | `-c
  `-{
    `-d
```
This structure is similar to that of the new AST, not the old AST

* Fix unit tests: another AST was incorrect, now is fixed

Code: `auto var{{1,a::b{2,3}}, {4,a::b{5,6}}};`

Old AST:
```
{
|-var
`-{
  `-,
    |-,
    | |-1 'signed int'
    | `-{
    | | |-::
    | | | |-a
    | | | `-b
    | | `-,
    | | | |-2 'signed int'
    | | | `-3 'signed int'
    `-{
      `-,
        |-4 'signed int'
        `-{
          |-::
          | |-a
          | `-b
          `-,
            |-5 'signed int'
            `-6 'signed int'
```
New AST:
```
{
|-var
`-,
  |-{
  | `-,
  | | |-1 'signed int'
  | | `-{
  | | | |-::
  | | | | |-a
  | | | | `-b
  | | | `-,
  | | | | |-2 'signed int'
  | | | | `-3 'signed int'
  `-{
    `-,
      |-4 'signed int'
      `-{
        |-::
        | |-a
        | `-b
        `-,
          |-5 'signed int'
          `-6 'signed int'
```

* Fix unit tests: missing ; after class, resulting in incorrectly being marked as cpp11init

Because of the missing `;` after the class declaration, it was marked as a cpp11init block.
Which it isn't, and which now throws an exception

* Fix cpp11init to let unit tests pass again

The following unit tests failed on the newly introduced throws, because the code for these tests incorrectly marked some tokens as cpp11init:
TestVarID::varid_cpp11initialization
TestTokenizer::checkRefQualifiers

* Fix typo

* Improve check for void trailing return type

Observation: the only function body _not_ containing a semicolon, is a void function: something like
   auto make_zero(ini& i) -> void {
     while(--i > 0) {}
   }
Non-void function? Then it must return a value, and thus contain a semicolon, which is checked for a few lines later.

* Fix cpp11init with templated trailing return type

In the following example, vector was marked as cpp11init due to the mismatch of `%any% {`
auto f() -> std::vector<int> { return {}; }

I made the assumption that whenever "%any% {" matches, endtok must be set too.
If this assumtion doesn't hold (so "%any% {" matches, but endtok == nullptr), then the for-loop would search all the way to the end of stream. Which I guess was not the intention.

* Remove comments

Fix #11351 Assert failure in templatesimplifier.cpp (#4552) 2022-10-16 19:34:25 +02:00
gerboengels 221873e69f
Fix #11319 (#4549) 
In this example:
```
//template<std::same_as<int> T> // <= works
template<same_as<int> T>        // <= didn't work
void f()
{}
```
the changed line used to match to `< same_as <`, therefore skip creating links.
The `%op% %name% <` already feels a bit like a workaround. So adding the condition that $op$ shouldn't be a comparison operator, but part of the template, seemed reasonable to me

Fix defaulted and deleted functions (#4540) 
* Fix 9392, but for destructors: out-of-line defaulted destructors skipped everything after

Context:
```
struct S {
    ~S();
};

S::~S() = default;

void g() {
    int j;
    ++j;
}
```
Everything after `S::~S() = default;` was skipped, so the uninitialized variables in g() weren't found.

Out-of-line destructors are useful e.g. when you have a forward declared unique_ptr in the .h,
and `= default` the destructor in the .cpp, so only the cpp needs to know the header for destructing
your unique_ptr (like in the pImpl-idiom)

* Fix unit test, by correctly fixing 10789

Previous commit broke this test, but also provided the tools for a cleaner fix

* Document current behaviour

* Rewrite control flow

* Fix deleted functions, which skipped everything after

`a::b f() = delete` triggered the final else in SymbolDatabase::addNewFunction,
which sets tok to nullptr, effectively skipping to the end of the stream.

* Remove troublesome nullptr, which skips every analysis afterwards

It was introduced in 0746c241 to fix a memory leak.
But setting tok to nullptr, effectively skipping to the end, seems not needed.

Previous commits fixes prevented some cases where you could enter the `else`.
This commit is more of a fall back.

* fixup! Fix deleted functions, which skipped everything after

`a::b f() = delete` triggered the final else in SymbolDatabase::addNewFunction,
which sets tok to nullptr, effectively skipping to the end of the stream.

* fixup! Fix deleted functions, which skipped everything after

`a::b f() = delete` triggered the final else in SymbolDatabase::addNewFunction,

* Make it heard when encountering unexpected syntax/tokens
