Daniel Marjamäki 3776604f06 SymbolDatabase: Add variable in if condition 'if (auto x = bar())' 2019-10-09 15:55:54 +02:00
Steve Mokris 506a952ad2 Parse `extern "C"`, and use it to avoid FP reference warnings (#2234)
Previously, cppcheck discarded the `extern "C"` specifier.  This patch modifies cppcheck to parse each as a Scope in the symbol database, then uses that scope to avoid false positives when making recommendations about changing a function argument to be a reference (since variable references is a C++ feature, unavailable in C, and thus unavailable in `extern "C"`).

IOBYTE c32a568c1f fix #8965 ("(debug) Executable scope 'x' with unknown function." with rvalue parameter in method) (#2237)
I fixed the AST enough to pass testrunner but I don't believe it is
correct.

This code:

void Foo4(int&&b);

has this AST:

( 'void'
|-Foo4
`-&& 'bool'
  |-int
  `-b 'signed int'

but I don't believe && should have `bool`.

shaneasd 7e54f989f9 Update symbol database such that the override keyword implies that the function is also virtual (#1907)
* Update symbol database such that the override keyword implies that the function is also virtual

* Add test case for implicit override

* change isVirtual to hasVirtualSpecifier

* fix method documentation for getVirtualFunctionCalls and getFirstVirtualFunctionCallStack

* Fix isImplicitlyVirtual to consider the override keyword and document logic

* Fix getFirstVirtualFunctionCallStack and getVirtualFunctionCalls to use isImplicitlyVirtual instead of isVirtual so new test case passes

Scott Furry a195477470 Correct Zero/Null as pointer constant (#1938)
Building with enhanced clang warnings indicated a large number of
instances with the warning:

`warning: zero as null pointer constant`

Recommended practice in C++11 is to use `nullptr` as value for
a NULL or empty pointer value. All instances where this warning
was encountered were corrected in this commit.

Where warning was encountered in dependency code (i.e. external library)
no chnages were made. Patching will be offered upstream.
