[clang][analyzer] Move checker alpha.unix.StdCLibraryFunctions out of alpha. (#66207) 2023-10-16 14:51:05 +02:00

4f0436dd15 [clang][analyzer] Merge apiModeling.StdCLibraryFunctions and StdCLibraryFunctionArgs checkers into one.
Main reason for this change is that these checkers were implemented in the same class
but had different dependency ordering. (NonNullParamChecker should run before StdCLibraryFunctionArgs
to get more special warning about null arguments, but the apiModeling.StdCLibraryFunctions was a modeling
checker that should run before other non-modeling checkers. The modeling checker changes state in a way
that makes it impossible to detect a null argument by NonNullParamChecker.)
To make it more simple, the modeling part is removed as separate checker and can be only used if
checker StdCLibraryFunctions is turned on, that produces the warnings too. Modeling the functions
without bug detection (for invalid argument) is not possible. The modeling of standard functions
does not happen by default from this change on.

1ea584377e A significant number of our tests in C accidentally use functions
without prototypes. This patch converts the function signatures to have
a prototype for the situations where the test is not specific to K&R C
declarations. e.g.,

  void func();

becomes

  void func(void);

This is the ninth batch of tests being updated (there are a
significant number of other tests left to be updated).

a787a4ed16 [analyzer][StdLibraryFunctionsChecker] Use Optionals throughout the summary API
By using optionals, we no longer have to check the validity of types that we
get from a lookup. This way, the definition of the summaries have a declarative
form, there are no superflous conditions in the source code.
