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'.
* Fixed#8960 ("(debug) Unknown type 'x'." with alias in template class alias)
This commit adds non-template type alias support to the template
simplifier. Only relatively simple type aliases are supported at this
time. More complex types will be added later.
--debug-warnings will show unsupported type aliases.
Type alias support will be removed from the symbol database in the
future. Type alias tests have been removed from the symbol database
tests.
* Add the changes.
* Fix codacy warning.
* Fix travis warnings.
* Fixed#8683 (Using deleted token with multiple template instantiations.)
* Fixed#8321 (heap use after free: templatesimplifier)
* Add a flag to Token indicating that it has a pointer to it.
* Run dmake
* Fix one source of list pointers to deleted tokens.
Refactor TemplateSimplifier class to get access to template lists.
Remove many function parameters now that they are class variables.
Fix one source of list pointers to deleted tokens.
Add tests with no output to catch crashes.
* Run dmake again.
* Make 2 more functions private.
* Make requested changes.
* Missed one change request.
* Use TokenList rather than Tokenizer.
* Move TokenAndName constructor to cpp file so token.h is not needed in header file.
* Allow syntax "typedef 'typename' unsigned 'typename' (functon_name)()" for some old libraries
https://trac.cppcheck.net/ticket/7792
* Unnecessary check of "tokOffset", match-function already checks if it is null
* add testcase ticket #7792: simplifyTypedef124
* 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
Also made sure to use the correct constructor for Token in other tests.
* 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
Renamed _listEnds to _tokensFrontBack.
* Fixing stylistic nits
Renamed _listEnds to _tokensFrontBack.
* 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.
* 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
* Removed unneeded deleteToken
* Removed extra whitespace
* Don't remove the volatile keyword so we can properly overload functions.
I fixed all the checks that had tests that use volatile. There will
probably be more changes needed due to lack of test coverage for
volatile in some checks.
* Fix unused private function warning.
* Add support for namespace aliases and C++17 nested namespaces.
These are implemented as tokenizer simplifications so changes are not
needed to the tokenizer and symbol database.
* Fix codacy warning.
