From f1a4697c236aae8f7d13042e4c6a31c228aa8595 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Tue, 7 Feb 2023 08:51:06 +0100 Subject: dump: Assert cpu_get_note_size() can't fail MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The only way cpu_get_note_size() can return a negative value is integer overflow in the non-stub versions, which is a programming error. The stub version is not actually reachable, because the cpu_get_dump_info() stub will fail first. Use assert(). This gets rid of another use of QERR_UNSUPPORTED.
