IOBYTE 46b543ba27 template simplifier: stop running passes when nothing was simplified. (#1914) 2019-06-23 10:55:09 +02:00
IOBYTE 246576fceb Fixed #9178 (Assertion `brackets1.empty() == false' failed on valid C++ code) (#1905)
This fixes a nasty intrinsics related bug causing instantiations that
shouldn't happen.

Ken-Patrick 66ebc187f6 Cleanup some const_cast of Token* (#1886)
* Add non const version of some methods of Token

The aim is to reduce the (ab)use of const_cast.

* Cleanup some more const_cast in valueflow

* Remove useless const_cast

* Remove some const_cast from templatesimplifier

IOBYTE 75720528b0 template simplifier: add 2 new template parameter simplifications (#1884)
* template simplifier: add 2 new template parameter simplifications

int{} -> 0
decltype(int{}) -> int

This fixes reduced test cases like #9153.  I'm not sure they will help
real world code that much.

It was necessary to increase the pass count to 4 to get #9153 completly
simplified.

* relax decltype(type{}) simplification to any type

IOBYTE 2a4b28c267 Fixed #9155 (Syntax error on valid C++ code) (#1880)
Refactored simplifyTemplateAliases to iterate over template type aliases
rather than instantiations. This fixed template type aliases that were
not templates.

Don't instantiate templates in template type aliases. They will get
instantiated once the type alias is instantiated. This required
increasing the template simplifier pass count to 3 so one of the
existing tests continued to work.

IOBYTE 5af8beecf6 template simplifier: specialized member class not recognized causing wrong instantiation (#1876)
Specialized member classes declared outsize the class were not
recognized. This caused the the member class to be instantiated rather
than the specialized class. We already had a test for this but it was
wrong so it went unnoticed.

Paul Fultz II eb1c9ba357 Cache template name position to improve performance
This improves the performance of the templatesimplefier by caching the template name position. I am not sure if the works entirely correctly but all the tests do pass with this change. Running this with gtest headers without removing unused template headers the time went from 48s to 5s, almost a 10x improvement.

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.

IOBYTE 165cce5dcc template simplifier: fix some crashes (#1772)
Fix some crashes caused by the template simplifier generating bad code

Sorry but there are no tests because I was unable to get C-Reduce to
create examples that were not garbage code.

instantiations.

* 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.
