+# Inline Assembly Safety Directive
+
+## Overview
+
+The `.inline_asm_mode` directive provides enhanced safety for inline assembly blocks by warning about potentially unsafe label usage. This directive helps prevent common errors where programmers create non-local labels in inline assembly that could be inadvertently jumped to from external code.
+
+## Syntax
+
+```assembly
+.inline_asm_mode strict   # Enable strict mode - warn on non-local labels
+.inline_asm_mode relaxed  # Disable strict mode (default)

I'm especially willing to consider a better name for this directive.
