From e769f68613ee4f84c8e2aea784335df74ceea397 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 23 Mar 2015 11:06:10 +0100 Subject: armv8: semihosting: do not inline trap call The semihosting trap call does not like being inlined, probably because that will mean register reordering screwing up the return value in r0, so tag this function "noinline".
