The __LINE__ macro creates challenges for binary diffing. When a .patch file adds or removes lines, it shifts the line numbers for all code below it. This can cause the code generation of functions using __LINE__ to change due to the line number constant being embedded in a MOV instruction, despite there being no semantic difference. Avoid such false positives by adding a fix-patch-lines script which can be used to insert a #line directive in each patch hunk affecting the line numbering. This script will be used by klp-build, which will be introduced in a subsequent patch.
