Fix constParameterPointer regression (#5361) 
Commit 73251544a ("Fix #11842 FN constParameterPointer with library
function (#5257)") most likely introduced a regression for (C) function
pointers passed to functions provided by the standard library that
cppcheck has knowledge about.

Fix 11579: false negative: knownConditionTrueFalse with non-bool as bool parameter (#5349) 
This adds a new checker to check for pointer to bool conversions that
are always known. I removed the previous knownConditionTrueFalse checks
since this was too noisy.

Improve knownArgument to check arguments to any nary function (#5348) 2023-08-19 19:59:15 +02:00
Oliver Stöneberg bfb50ca9d8
removed unnecessary `Settings` parameter from `Check::runChecks()` and made `Tokenizer` a reference (#5308) 
There was no need for the `Tokenizer` parameter to be a pointer as it
could never be `nullptr` and was also dereferenced without checking
first.

As a reference to the `Settings` was already available via the
`Tokenizer` there was no need to pass it separately. In the production
code there will only be one instance of it but in the tests we could
have accidentally passed a different one.

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 The version is AUR is still outdated and also doesn't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