From 2b22a99c65c437891ab88703dff25e256f78c21f Mon Sep 17 00:00:00 2001 From: Sjoerd Simons Date: Fri, 4 Dec 2015 23:27:38 +0100 Subject: [PATCH] lib: Split panic functions out of vsprintf.c To allow panic and panic_str to still be used when using tiny-printf, split them out into their own file which gets build regardless of what printf implementation is used.
