From 5ba3602e4580d6b65dacf4292a031627f93e1167 Mon Sep 17 00:00:00 2001 From: Taylor Beebe Date: Wed, 28 Feb 2024 10:47:23 -0800 Subject: BaseTools: Use Stronger Matching for NULL Linked Libraries To prevent the possibility that a library with a name like NULLTestLib is interpreted as a NULL linked library, use more explicit pattern matching to ensure that the library name follows the pattern NULL%d.
