We should fix the pthread_exit() declaration instead, e.g.
FreeBSD
has this:
void pthread_exit(void *) __dead2;
Does that map to gcc noreturn? And does newlib have that?
Yes, or Noreturn if you use the appropriate C++ version. Needs
<sys/cdefs.h>.
That moves the noreturn warning.
/data/home/joel/test-gcc/install-head/sparc-rtems4.12/include/pthread.h:
In function 'pthread_exit':
../../../../../../rtems/c/src/../../cpukit/posix/src/pthreadexit.c:78:1:
warning: 'noreturn' function does return
}
^
Other than marking pthread_exit's return as unreachable, do you have
another suggestion?
