From 0da91df25d2425c96f308296ccebe08829d962f8 Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Thu, 23 Mar 2023 13:50:35 +0100 Subject: tests: py: extend test-cases for mark statements with bitwise expressions Add more tests to cover bitwise operation. Shift operations are used on constant value which are reduced at evaluation time. Shift takes precendence over AND and OR operations, otherwise use parens to override this.
