From 0c918e753f8c03b0308a635c0721a8c24d738d4a Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Fri, 21 Aug 2020 12:42:59 -0700 Subject: arm/build: Assert for unwanted sections In preparation for warning on orphan sections, enforce expected-to-be-zero-sized sections (since discarding them might hide problems with them suddenly gaining unexpected entries).
