+bugprone-signed-bitwise
+=======================
+
+Finds uses of bitwise operations on signed integer types, which may lead to
+undefined or implementation defined behavior.
+
+Performing bitwise operations on signed integers can be confusing and may
+lead to undefined or implementation dependent behavior. In particular, right
+shift a signed integer is implementation dependent, while left shift a signed
+integer may result in undefined behavior.
+
+.. code-block:: c++
+
+ int main(){
+ int x = -4;
+ int y = x >> 1; // y can be -2 or 2147483646
+ }
+
+Options
+-------
+
+.. option:: IgnorePositiveIntegerLiterals
+
+ If this option is set to `true`, the check will not warn on bitwise
operations with positive integer literals, e.g. `~0`, `2 << 1`, etc.
