GCC's treatment of functionpointers here is just WRONG.There are a couple of issues. The most serious is the following:We have the following code from __pthread_sigaction in the .i file: if (old == ((__sighandler_t) 1) || old == ((__sighandler_t) 0) || old == ((__sighandler_t) -1)) __sighandler[sig].old = (arch_sighandler_t) act->__sigaction_handler.sa_handler;This is what the above turns into in the tree dump filebug321785.c.t02.original: if ((void (*<T2bd>) (int)) old - 2B > -4B) { __sighandler[sig].old = (void (*<T431>) (int, struct sigcontext *)) act->__sigaction_handler.sa_handler; }I don't believe that the transformation is valid.
hmm, looks like another build_range_test bug. -- Pinski
