* [ClangTidy] Separate tests for infrastructure and checkersDmitri Gribenko2019-10-111-468/+0
| | | | | | | | | | | | | | | | | | | | Summary: This change moves tests for checkers and infrastructure into separate directories, making it easier to find infrastructure tests. Tests for checkers are already easy to find because they are named after the checker. Tests for infrastructure were difficult to find because they were outnumbered by tests for checkers. Now they are in a separate directory.

* [clang-tidy] Resubmit hicpp-multiway-paths-covered without breaking testJonas Toth2018-03-211-0/+468
| | | | | | | | | | | | | | | | | | | | | | | | The original check did break the green buildbot in the sanitizer build. It took a while to redroduce and understand the issue. There occured a stackoverflow while parsing the AST. The testcase with 256 case labels was the problem because each case label added another stackframe. It seemed that the issue occured only in 'RelWithDebInfo' builds and not in normal sanitizer builds. To simplify the matchers the recognition for the different kinds of switch statements has been moved into a seperate function and will not be done with ASTMatchers. This is an attempt to reduce recursion and stacksize as well. The new check removed this big testcase. Covering all possible values is still implemented for bitfields and works there. The same logic on integer types will lead to the issue. Running it over LLVM gives the following results: Differential: https://reviews.llvm.org/D40737 llvm-svn: 328107
* [clang-tidy] revert hicpp-multiway-paths-coveredJonas Toth2017-11-201-467/+0
| | | | | | | | The address sanitizer found a stackoverflow with this patch. There is no obvious fix. This patch will be reapplied when the problem is found. llvm-svn: 318670
* [clang-tidy] Add new hicpp-multiway-paths-covered check for missing branchesJonas Toth2017-11-181-0/+467
Summary: This check searches for missing `else` branches in `if-else if`-chains and missing `default` labels in `switch` statements, that use integers as condition. It is very similar to -Wswitch, but concentrates on integers only, since enums are already covered. The option to warn for missing `else` branches is deactivated by default, since it is very noise on larger code bases. Running it on LLVM: {F5354858} for default configuration {F5354866} just for llvm/lib/Analysis/ScalarEvolution.cpp, the else-path checker is very noisy!
