From dc66ff6220f0a6c938df41add526d645852d9a75 Mon Sep 17 00:00:00 2001 From: Roel Kluin Date: Thu, 22 Jan 2009 15:16:14 +0000 Subject: SH: fix start_thread and user_stack_pointer macros Fix macros start_thread and user_stack_pointer. When these macros aren't called with a variable named regs as second argument, this will result in a build failure.
