Simon Martin eaaff30e65 Ticket #8878: Properly simplify typedefs within template instantiations. (#1656) 2019-02-10 09:45:33 +01:00
Daniel Marjamäki bd7790fd8c Update copyright year 2019-02-09 07:24:06 +01:00
IOBYTE 7025254c26 Fixed #8969 (syntax error: template) (#1647)
Fixed template detection to handle multi-token template parameters.
2019-02-07 08:50:49 +01:00
IOBYTE 1faae52d06 Fixed #8960 ("(debug) Unknown type 'x'." with alias in template class alias) (#1643)
* 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.

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

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.

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

however not update the description of the function, do this now.

IOBYTE fcde1d80e9 Fix #8382 (Syntax error when scanning code with template and attribute) (#1089)
* Fix #8382 (Syntax error when scanning code with template and attribute)

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.

* Remove all C++ style attributes.

Remove all C++ style attributes when C++ version is 11 or greater.
Rename simplify function to simplifyCPPAttributes.
Handle more cases of roreturn function attribute.

Alexander Mai 68eb6c4e6f Refactoring: Add Tokenizer::findGarbageCode to time report. The method now calls syntaxError instead of returning an invalid token 2018-02-05 21:47:33 +01:00

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.

David Hallas 4d18d3948f Fixes issue with case inside switch that is not a compound statement (#1031)
* 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.

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.
