This commit tweaks the interface of `CheckerRegistry::addChecker` to
make it more practical for plugins and tests:
- The parameter `IsHidden` now defaults to `false` even in the
non-templated overload (because setting it to true is unusual,
especially in plugins).
- The parameter `DocsUri` defaults to the dummy placeholder string
`"NoDocsUri"` because (as of now) nothing queries its value from the
checker registry (it's only used by the logic that generates the
clang-tidy documentation, but that loads it directly from `Checkers.td`
without involving the `CheckerRegistry`), so there is no reason to
demand specifying this value.
In addition to propagating these changes, this commit clarifies,
corrects and extends lots of comments and performs various minor code
quality improvements in the code of unit tests and example plugins.
I originally wrote the bulk of this commit when I was planning to add an
extra parameter to `addChecker` in order to implement some technical
details of the CheckerFamily framework. At the end I decided against
adding that extra parameter, so this cleanup was left out of the PR
https://github.com/llvm/llvm-project/pull/139256 and I'm merging it now
as a separate commit (after minor tweaks).
This commit is mostly NFC: the only functional change is that the
analyzer will be compatible with plugins that rely on the default
argument values and don't specify `IsHidden` or `DocsUri`. (But existing
plugin code will remain valid as well.)
Well, yes. It's not pretty.
At least after this we would have a bit more unique pointers than
before.
This is for fixing the memory leak diagnosed by:
https://lab.llvm.org/buildbot/#/builders/24/builds/5580
And that caused the revert of #127409.
After these uptrs that patch can re-land finally.
This commit deletes the "simple" constructor of `CallDescription` which
did not require a `CallDescription::Mode` argument and always used the
"wildcard" mode `CDM::Unspecified`.
A few months ago, this vague matching mode was used by many checkers,
which caused bugs like https://github.com/llvm/llvm-project/issues/81597
and https://github.com/llvm/llvm-project/issues/88181. Since then, my
commits improved the available matching modes and ensured that all
checkers explicitly specify the right matching mode.
After those commits, the only remaining references to the "simple"
constructor were some unit tests; this commit updates them to use an
explicitly specified matching mode (often `CDM::SimpleFunc`).
The mode `CDM::Unspecified` was not deleted in this commit because it's
still a reasonable choice in `GenericTaintChecker` and a few unit tests.
This avoids recomputing string length that is already known at compile time.
It has a slight impact on preprocessing / compile time, see

This a recommit of e953ae5bbc313fd0cc980ce021d487e5b5199ea4 and the subsequent fixes caa713559bd38f337d7d35de35686775e8fb5175 and 06b90e2e9c991e211fecc97948e533320a825470.
The above patchset caused some version of GCC to take eons to compile clang/lib/Basic/Targets/AArch64.cpp, as spotted in aa171833ab0017d9732e82b8682c9848ab25ff9e.
The fix is to make BuiltinInfo tables a compilation unit static variable, instead of a private static variable.

`CallDescriptions` deserve its own translation unit.
This patch simply moves the corresponding parts.
Also includes the `CallDescription.h` where it's necessary.

`PathSensitiveBughReport` has a function to mark a symbol as interesting but
it was not possible to clear this flag. This can be useful in some cases,
so the functionality is added.
