From 883debc22e30a947fe5858cc07ee5aebd3d07a2e Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Sun, 16 Aug 2015 20:59:56 -0700 Subject: [PATCH 5/7] Always use -O2 for compiling fork.c When compiling in thumb mode for arm with -Os gcc gives up since it can not find registers to spill. So we use -O2 option for compiling fork.c It may be addressable in gcc.
