Denis 68e6a440ff Fix adding unescaped slash token when splitting gcc case range. (#1987)
* Fix adding unescaped slash token when splitting gcc case range.

Construction like case '!'...'~' converted to a list of separate case
tokens. When slas '\' symbol appears as a part of this list it was added
"as is", but it should be escaped like '\\' to be valid c++ code.

* Add test for switch-case range with slash

IOBYTE 9569fa1374 Partial fix for #9191 (simplifyTypedef: Problem when namespace is used) (#1952)
* Partial fix for #9191 (simplifyTypedef: Problem when namespace is used)

This fixes simplifyUsing which has the same problem as simplifyTypedef.

simplifyUsing was designed to support using namespace but it was never
implemented. The changes are minor to add it.

simplifyTypedef requires much more work to support using namespace.

* reduce scope of variable

rebnridgway 0d7836f3a0 Calculate token scopes in advance rather than as the tokenlist is iterated (#1882)
* Added scopeinfo member to token class

Moved ScopeInfo2 declaration here as well because that's where it needs to be now.

* Added scopeinfo accessors and declaration to class

* Add new method for calculating scopes

This replaces the methods in the TemplateSimplifier which calculate the current scope as the token list is iterated.  The old method required checking if the scope had changed for every token multiple times (for multiple iterations), which was surprisingly costly.  Calculating scopes in advance like this decreases runtime on a worst-case file by around thirty percent.
ScopeInfo objects are disposed of when the TemplateSimplification is done as they are not used later.

* Add calculateScopes method to header

* Removed code that calculated current scope

This has been replaced by code that calculates the scopes up front and stores them with each token, which is much faster.

* Fixed compile errors from extra parentheses

* Added missing code to fix memory leak

* Added code to actually clean up ScopeInfo structs

* Tidy up a dodgy for loop

* Convert argument to const ref

* Calculate missing scopes

As the templatesimplificator expands templates and does multiple passes it needs to make sure all scopes are calculated.

* Remove copying the scope to the next token

This is now done properly when scopes are calculated.

* Remove call to calculateScopes

This is now done by the TemplateSimplifier.

* Recalculate scopes for every pass of simplifyTemplates

* Add code to calculate extra scopes as they are added

I thought that this might be useful for calculating scopes when Tokens are created, but as there are several ways of creating Tokens that don't guarantee that they are placed in a list it is easier to just calculate scopes when you know you have a list and when you know you're adding to a list.

* Fix several bugs and poorly designed code

Remove the global scopes collection, and clean them up instead by iterating through the tokenlist to find them.  This means scopes can be calculated by functions in the Token class as well as in the Tokenizer class without leaking the scope object.
Fix a couple of bugs in the calculateScopes method and make it more efficient.

* Remove unnecessary calls to calculateScopes

* Move brace to correct position

Calculating scopes during insertToken only needs to happen if we created a new Token.

* Handle 'using namespace' declarations separately

This fixes a bug caused by a statement matching 'struct B < 0 > ;'

* Fix argument name mismatch

* Actually use newScopeInfo when inserting Token

* Switch to using shared_ptr to hold scopeInfos

This means ScopeInfo2 objects get properly cleaned up when they are no longer needed.

* Change ScopeInfo member to be a shared_ptr

* Update code to use shared_ptr

* Add missing include for shared_ptr

* Remove unnecessary cleanup code

This has been replaced by shared_ptr for ScopeInfo2 objects

IOBYTE e786c6b7d4 partial fix for #8663 (Stack overflow with template disambiguator) (#1801)
This fixes simplifyUsing to remove 'typename' and 'template' from type
aliases of the form: using T3 = typename T1::template T3<T2>;

This lets the template simplifier instantiate the type alias which will
then remove the using type alias.

The crash will still happen if there is no instantiation because the
type alias will not be removed.  The type alias is what cppcheck is
crashing on after the template simplifier and that still needs fixing.

This handles concatenated strings and characters from simplecpp.
Previously, L'c' would be preprocessed to the tokens  "L" and "'c'".
cppcheck would then remove the "L" token and set "'c'" to be a wide
character literal. Now, it needs to remove the prefix instead.

When doing this, add handling of utf32 encoded literals (U) and UTF-8
encoded literals (u8).

rikardfalkeborn dc4e7cef88 Run simplifyPlatformTypes on library return types (#1672)
Add a call to simplifyPlatformTypes() in
SymbolDatabase::setValueTypeInTokenList() to simplify return types of
library configured functions. This fixes the FN in #8141. Regression
tests are added, both for the original issue and another FN in the comments.

In order to do that, move simplifyPlatformTypes() to TokenList from Tokenizer.
This is a pure refactoring and does not change any behaviour. The code was
literally copy-pasted from one file to another and in two places
'list.front()' was changed to 'front()'.

When adding the call to simplifyPlatformTypes(), the original type of
v.size() where v is a container is changed from 'size_t' to 'std::size_t'.
Tests are updated accordingly. It can be noted that if v is declared as
'class fred : public std::vector<int> {} v', the original type of 'v.size()'
is still 'size_t' and not 'std::size_t'.

This commit adds non-template type alias support to the template

rebnridgway 42a65c5160 Fix crash bug #8579 (#1238)
* Added declaration for deletePrevious function

* Added definition for deletePrevious function

* Fixed crash from deleteThis invalidating pointers

The crash was caused by deleteThis() invalidating the pointer to a constant variable usage.  This happened when a usage followed an assignment.  This fixes bug #8579.

* Added tokensFront to match tokensBack

This means deletePrevious can set the list's front if necessary.

* Initialised tokensFront in appropriate places

* Switched to using default Token constructor

* Switched to using Token default constructor

* Switched to using default constructor for Token

* Added missing argument to Token constructor

* Changed to use default constructor for Tokens

* Switched to using default constructor for Tokens

* Switched to using default constructor for Token

* Added new test for deleting front Token

* Syntax error

* Replaced tokensFront and tokensBack with a struct

This decreases the size of the Token class for performance purposes.

* Replaced tokensFront and tokensBack with a struct

* Added tokensFrontBack to destructor

* Reworked to use TokensBackFront struct

Also ran astyle.

* Reworked to use TokenList's TokensFrontBack member

* Reworked to use TokensFrontBack struct

* Reworked to use TokensFrontBack struct

* Reworked to work with TokensFrontBack struct

* Removed unnecessary scope operator

* Added missing parentheses

* Fixed syntax error

* Removed unnecessary constructor

* Default constructor now 0-initialises everything

This is safer for not using a temporary TokensFrontBack object, and doesn't use delegating constructors which aren't supported yet.

* Fixed unsafe null check

* Added missing explicit keyword

* Fixing stylistic nits

Removed default constructor as it has been superseded by the single-argument constructor with a default argument value.
Renamed listEnds to tokensFrontBack.
Fixed if statement that was supposed to be adding safety but would actually cause a crash if tokensFrontBack was null.

* Fixing stylistic nits

Removed default constructor and replaced it with a single-argument constructor with a default value.

* Fixing stylistic nits

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

IOBYTE cefb2131c7 Add support for simple c++ 11 type ailases like: using INT = int; (#1024)
* Add support for simple c++ 11 type ailases like: using INT = int;

Only types supported by ValueType are supported. Complex types like
function pointers are not supported. Template type aliases are not
supported.

* Fix crash when type in using type alias is simplified away.

This fixes a crash when size_t is replaced with unsigned long in: using
size_t = unsigned long; by the tokenizer.

This does not fix the problem where Tokenizer::simplifyPlatformTypes()
simplifies away size_t in other cases.  This is only a problem when the
new type is different from the platform type.
