utils.h: added `startsWith()` and started using it (#5381)
This makes the code much more readable. It also makes it less prone to
errors because we do not need to specify the length of the string to
match and the returnvalue is clear.

The code with the bad returnvalue check was never executed and I added a
test to show that.

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.

Fix #11579 FN knownConditionTrueFalse with non-bool as bool parameter / #9450 string literal to bool conversion in function call (#5338) 2023-08-18 10:32:52 +02:00
Oliver Stöneberg 3cf9100198
fixed #6316 (Use std::to_string() in place of MathLib::toString() ...) - deleted default implementation of `Mathlib::toString()` (#5341)
It was also used inconsistently and seemed to imply there is some
special handling which wasn't the case. It was just an alias for
`std::to_string()` for non-`double` types. So there was no need for it.
