From a1b73c18724eb8cb75f7a60d851578d933c78095 Mon Sep 17 00:00:00 2001 From: "Andrew F. Davis" Date: Mon, 11 Jun 2018 14:04:17 -0500 Subject: [PATCH] arm: Do not clear LR on exception in SPL When an exception or interrupt occurs the link register (LR) may contain the source of the exception, although we do not print the value it may still be extracted with a debugger. When in SPL we loop on getting and exception, but use a linking branch, which over-writes the LR value, use a regular branch instruction here. Signed-off-by: Andrew F.
