Add noreturn function attribute
Introduce noreturn attribute and attach it to cpu_loop_exit as well as interrupt/exception helpers for i386. This avoids a bunch of gcc4 warnings. [ Note that this patch comes with a workaround to include qemu-common.h even in cases where is currently causes conflicts with dyngen-exec.h. I've been told that these conflicts will get resolved in the future (/me will try to have a look as well - as time permits). ] Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6303 c046a42c-6fe2-441c-8c8c-71466251a162
