bwoester 9b28499412 Import BCB6 projects (#1245)
* added support for reading borland c++ builder 6 projects

* add: fetch sysdefines from project
add: start providing bcb6 predefines (WIP)

* configure all the internal defines for BCB6

* make sure define strings don't start with ';'

* improvements on bwoesters BCB6 project support

- improved `*.bpr` XML handling by reducing the number of loops
- added `const` where aplicable
- optimized compiler argument parser performance
- reformatted code with provided astyle config

* - undo looping (keep it the same as the other implementations)
- keep parsing of cflags simple and separate from the synonym cleanup (no need for micro optimization in this place)
- move input validation to FileSettings::setDefines
- re-run astyle

* use [] instead of at() when comparing characters

* Remove duplicate namespace aliases so they don't produce syntax errors.

DACA2 results showed new SymbolDatabase syntax errors when duplicate
namespace aliases were simplified improperly. The solution is to remove
them in the tokenizer when found.

* Add tests for deleting namespace aliases at end of token list.

* Use eraseTokens to delete multiple tokens at once.

rebnridgway cf6e72b150 Optimised simplifyKnownVariables (#1205)
* Optimised simplifyKnownVariables

Changed the check for references to constant variables so instead of iterating through all tokens looking for references (which is very slow for large files), usages of each known variable are recorded so each usage can be checked for whether or not it is a reference.  Just checking known usages is a lot quicker than checking through all tokens.

* Fixed test error caused by incorrect code

* Fixes to constant variable simplification optimisation

Indexing variables by varId is easier than by Token pointer, but means we also have to store a reference to the constant variable Token in another collection.
Switched to using unordered_map over map as it has slightly better find performance.

* Fixed incorrect simplification behaviour

This should remove constant variables correctly and efficiently.  Requires additional functions, Token::deleteThisInPlace() and TokenList::front(Token*).

* Added setter for TokenList::first

This allows code that adds and removes Tokens from the list to do so without copying nodes into other nodes, which sometimes create difficulties.

* Added deleteThisInPlace function

This allows a token to delete itself without invalidating pointers to the node after it.  If this token is the first or last in a list the calling code will have to remember to change the list's front or back.

* Added declaration for deleteThisInPlace()

* Removed premature MatchCompiler optimisation

* Added and removed some functions

Added declaration for deleteToken(Token*) which deletes a single token from the list
Removed public front(Token*) because it broke encapsulation

* Implemented deleteToken(Token*) function

* Removed 'delete this' from deleteThisInPlace

* Switched to using safer function

TokenList::deleteToken is better than calling straight into Token::deleteThisInPlace because it doesn't call delete this and doesn't break the TokenList's encapsulation.

* Replace constant variables in reverse order

This fixes the problem where you have two constant value assignment statements in a row.  Replacing and deleting them in reverse order means we avoid the problem of deleteThis() potentially invalidating the pointer to the start of the next assignment statement

* Removed unneeded and unsafe deleteThisInPlace

* Removed unneeded and unsafe deleteThisInPlace

* Removed unneeded deleteToken

saved incomplete. This fix searches for the second instead of the last
colon and uses the data after the second colon as the path of the source
file.

rebnridgway 995b496ddf Add suppressions to the XML dump (#1166)
* Added parsing suppressions from dump xml.

* Added code to dump suppressions to an xml file

* Added declaration for dump function

* Suppressions will now be written to the xml file when a dump is requested

* Fixed syntax error

* Removed excess whitespace

* Fixed indentation to be consistent

* Fixed indentation to be consistent

* Fixed indentation to be consistent

* Added missing include for ErrorLogger::toXml

* Fixed suggestions from pull request #1166

Switched to using ranged for loop to iterate through suppressions.
Made the line number attribute optional, rather than 0 if not specified.  This means when Python deserialises it it will be None, which is more pythonic.

* Implemented checking suppressions in reportError

This modification expects suppressions and a function to be called to write a line of output to be passed in.  The function checks if any of the suppressions match the warning (with the new Suppression.isMatch function) and if so returns None.  This change maintains the old behaviour of returning the warning text, but adds the possibility of returning None if the warning was suppressed.

* Fixed code quality warnings

* Removed more extraneous whitespace

rikardfalkeborn 57019c0128 Fix comment in Tokenizer::simplifyMathFunctions (#1179)
In 9cea2d6df, simplifications were removed for a number of functions
which should instead be handled with configurations. The commit did
however not update the description of the function, do this now.

Also sin() and sinh() and their float and long double versions were
missing from the comment so add these as well.

This commit only addresses #8382. There are issues concerning which
versions of C++ should be supported and also generic C++ 14 attribute
support which can be revisited later.

Jørgen Kvalsvik a61f21d1b6 Accept nested templates in tokenizer-simplify (#1070)
The following snippet triggerd the error:

template<typename DerivedT>
template<typename T>
auto ComposableParserImpl<DerivedT>::operator|( T const &other ) const -> Parser {
    return Parser() | static_cast<DerivedT const &>( *this ) | other;
}

Whenever simplifyFunctionParameters was called on a templated class'
templated member function (and probably any nested template), the
tokenizer would recognise it as a syntax error, assuming that return
type *must* come after a template<> token.

symboldatabase: Fix potential null pointer dereference (#1072)
There is a  potential `nullPointer` dereference in symboldatabase. This PR attempts to fix this. Additionally, this could be detected by Cppcheck as well. 

Here is a reduced and compilable testcase, where Cppcheck fails to detect a potential `nullPointer` dereference:

```
class Scope
{
public:
    bool bar();
    int *definedType;
};

int f(Scope *new_scope)
{
    int ret = 1;
    if (new_scope)
    {
        if (new_scope->bar())
        {
            if (!new_scope->definedType) {} // check for null
            ret = *new_scope->definedType; // dereference
        }
    }
    return ret;
}
```

* Fixes issue with case inside switch that is not a compound statement was treated as garbage

This fixes an issue with the check for case keywords outside of switch
detection that would treat a case statement inside a switch that is not
a compound statement as garbage, but this is perfectly valid C++. This
construct is used in several libraries, i.e. Google Test.

* Tweak check and handle missing semicolon

Tweaks the check with feedback from danmar.
Handle the case where there is no semicolon and document it with a unit
test.
