Add special function to match lifetimes (#5320)
This also removes the termination checking in `valueFlowUninit` as this
causes a lot of FNs.

ValueFlow: pass `SymbolDatabase` by reference into `ValueFlow::setValues()` (#5295) 2023-08-07 18:41:50 +02:00

pass `TokenList` as reference into `ValueFlow::setValues()` (#4868)
This avoid lots of unchecked pointer dereferences.

There was a single case which checked it and that looked like a
leftover. The only way this might have been a `nullptr` pointer was
through several default constructors which were not used at all so I
removed them.

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 The version is AUR is still outdated and also doesn't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.
