From 7b4afdbe8199a85c4a187d4ee3763b09606df121 Mon Sep 17 00:00:00 2001 From: Thomas Leonard Date: Fri, 8 Aug 2014 16:47:32 +0100 Subject: [PATCH] mini-os: move poor rand function to test.c It's only used by test.c and probably isn't something that should be exposed for general use (it just calls gettimeofday). This is also useful for ARM, which doesn't use math.c, where this used to live.
