Lauri Nurmi 3bbd9fc9a4 Replace "virtual method" with "virtual function" in messages.
The term "method" is not really a part of C++ terminology.

test/cfg/runtests.sh: Qt test: Fix syntax check when "-fPIC" is required (#1600)
On linux systems (like travis) Qt often seems to be built with the option "reduce_relocations" which requires an application using it to specify the option "-fPIC".

juremenart 45def06d59 fix trailing / from CMAKE JSON file and update unittests to cover both (w and w/o cases) (#1592)
* fix for CMake compile_commands.json input - director does not include trailing / which makes include directories wrong - so add it if it doesnt exist

* fix the bugfix for trailing / in the directory name of CMAKE JSON file, add also new test case to see if it works in both cases (with and without trailing /)

* revert adding accidental new line

Sebastian 7a59949cb4 qt config test: Use pkg-config to retrieve Qt settings. (#1571)
To be able to use real Qt-Code in "test/cfg/qt.cpp" and still do a
syntax check the Qt settings are read out via pkg-config now if it is
available. This way the test now can contain Qt macros and functions and
the syntax check can still be used.
Additionally the same options as for the other tests are used now for
the Qt config tests.
Installing the package "qtbase5-dev" should be enough to enable the
syntax checks (already installed for travis tests).

This fixes valueflow to have a value for `||` operator here:

	bool a = (4 == 3); // <-- 0
	bool b = (3 == 3); // <-- 1
	return a || b; // <-- 1
}

rikardfalkeborn 13ffefc8b8 Valueflow: Fix right shift with more than 31 bits (#1553)
When comparing if the shift is large enough to make the result zero, use
an unsigned long long to make sure the result fits. Also, a check that
avoids setting the value if the shift is equal to or larger than the
number of bits in the operand (this is undefined behaviour). Finally,
add a check to make sure the calculated value is not too large to store.

Add test cases to cover this.

This was detected by an MSVC warning.

valueflow.cpp(1350): warning C4334: '<<' : result of 32-bit shift implicitly
                     converted to 64 bits (was 64-bit shift intended?)
