* template simplifier: make sure all instantiations are found and expanded in #5097
* template simplifier: check output on another test
* template simplifier: add output to another test
* template simplifier: instantiate template class when something inside class instantiated.
* template simplifier: add output to another test that now works
* Fixed#8962 ("(debug) Unknown type 'T'" with template typename parameter)
Only simple one parameter template functions with one function parameter
are supported.
* Added TODO test case for FIXME.
* Fixed#8971 ("(debug) Unknown type 'x'." using alias in class members)
* template simplifier: partial fix for #8972
Add support for multi-token default template parameters.
* template simplifier: fix for #8971
Remove typename outside of templates.
* 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.
* template simplifier: fix crash on windows
Use right token when searching for template type alias to delete.
* template simplifier: fix a cppcheck warning
* out of line member functions are a namespace
* template<...> and *_cast<> can't be instantiations
* refactor code to use less function parameters
* fix instantiation scopes
* use full name with namespace when available
* fallback to just matching names when full name doesn't match
* use already cached name token rather than recalculating it
multiple times
* cache end of template parameters token and use it rather than
recalculating it multiple times
* remove unnecessary end of template token and name token checks
* remove function parameter that is already contained in another
parameter

* templatesimplifier: cleanup
since 48c960f56c showing:
lib/templatesimplifier.h:279:16: warning: private field 'mTokenizer' is not used
[-Wunused-private-field]
Tokenizer *mTokenizer;
* Code changes for Token::mImpl optimisation
* Added new TokenImpl optimisation
Moving members to the TokenImpl struct reduces the size of the Token class, which is a fairly significant optimisation. In my testing on Windows with 32-bit Release-PCRE, this change reduced the size of the Token class from 108 bits to 52 bits and reduced run-time of my test case by around 20%.
* Several optimisations
Deleted some code that ran very slowly and did nothing, as there is no need to change a Token's string to null if you are about to delete it.
Added a frontToken to simplifyCalculations to reduce the amount of work it has to do on already-simplified calculations.
Moved template removal to the end of the list as this reduces redundant iteration and saves time.
* Added tok argument to simplifyCalculations
This means callers can avoid unnecessary work if they know which tokens have already been simplified. Passing nullptr indicates the original behaviour (starting from the front of the list).
* Removed mention of member from another change
* Re-added and optimised some code deleted in error
Changing mTemplateInstantiations to a vector avoids the high cost of doing repeated linear searches. Changing how the code iterates through the array was necessary because the vector can be resized at several points during the loop, which breaks existing references and iterators.
* Changed mTemplateInstantiations to a vector
This is an optimisation that makes repeated linear searches of this collection significantly faster.
Also added a copy constructor to TokenAndName so code can make copies of these objects to keep a reference if a vector gets resized.
* A cleaner optimisation to removing template tokens
This reverts the previous change to made mInstantiatedTemplates a vector and the iterator changes to support this, and makes mTypesUsedInTemplateInstantiation so the eraseTokens logic can be unified.
* Reverted vector to list
Also made mTypesUsedInTemplateInstantiation a vector of TokenAndName objects so it can share the same logic as the other members.
* Added member for template simplifier pointer
This can be used more efficiently than marking Tokens with a flag and then searching through all templates to find the one that matches.
* Turned loop inside out
This means we only have to iterate through the std::list once. std::list is very expensive to iterate through.
* Latest code from danmar and fixed optimisations
In particular I have optimised simplifying template instantiation names as this was incredibly slow because of the number of times it had to iterate through the template instantiation list. Previous optimisations to this weren't very effective and broke some edge cases.
* Added changes from danmar
Made mExplicitInstantiationsToDelete a vector of TokenAndName to be consistent with the rest of the members, which are cleaned up very efficiently.
* Tokens can have many templateSimplifierPointers
* templateSimplifierPointers must be kept in sync
* Modify template simplifier to add forward declarations of some template functions so symbol database can make sense of the expanded templates.
* Fix travis.
It is possible to define default template parameter values in forward
declarations and not define any in the actual declaration. Cppcheck
ignores forward declarations and only uses the default values in the
actual declaration so default values in forward declarations are copied
to the actual declaration when necessary.
* Fix specialized template regression.
Only check for instantiation of template being processed rather than
count of all instantiations.
* Add 2 more tests.
