From e8006b060f3982a969c5170aa869628d54dd30d8 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Sun, 18 May 2008 20:47:12 +0200 Subject: [PATCH] m68k: Make gcc aware that BUG() does not return Use `__builtin_trap()' instead of `asm volatile("illegal")' in the m68k BUG() macros (as suggested by Andrew Pinski), to kill warnings in code that assumes BUG() does not return.
