# `-allow-enabling-analyzer-alpha-checkers` should be passed to clang-tidy for CSA checkers named `clang-analyzer-alpha.*`
# `aggressive-binary-operation-simplification` should be enabled (via `-Xclang -analyzer-config -Xclang aggressive-binary-operation-simplification=true` in clang)
# there is some problem in `clang-analyzer-alpha.clone.*`, so do not enable it
# `clang-analyzer-alpha.deadcode.*` is just too verbose to enable
