Fix FP badBitmaskCheck in nested binary expressions (#5316) 
If one operand is another binary expression, recursively ensure that no
nested operands are expanded macros.

avoid some redundant and unused settings in tests among other cleanups / added and used `WARN_UNUSED` attribute (#5284) 2023-08-09 12:43:55 +02:00

cleaned up includes based on include-what-you-use / iwyu.yml: updated to yet another distro to get the latest version and updated the Chaotic-AUR key (#5267) 
This is a mess. The version is AUR is still outdated and also doesn't
install anymore. Fedora 38 carries the latest version of it so use that
now. Keep the old steps in case we need to switch again in the future.

Ignore zero valued enum entries from badBitmaskCheck (#5195) 
Usage of zero valued enum entries can be used for documenting purposes
and should be ignored just like zeroes expanded from macros.

Fix #11789 FP knownConditionTrueFalse with std::vector::size() (#5184) 
There is special handling for `size_t` in
`ValueType::fromLibraryType()`, which gets preempted if it is also
configured as a podtype.
