/* This testcase originally provoked an unaligned access fault on Alpha. Since Digital Unix and Linux (and probably others) by default fix these up in the kernel, the failure was not visible unless one is sitting at the console examining logs. So: If we know how, ask the kernel to deliver SIGBUS instead so that the test case visibly fails. */ #if defined(__alpha__) && (defined(__linux__) || defined(__osf__)) #ifdef __linux__ #include <asm/sysinfo.h> #include <asm/unistd.h> static inline int setsysinfo(unsigned long op, void *buffer, unsigned long size, int *start, void *arg, unsigned long flag) { syscall(__NR_osf_setsysinfo, op, buffer, size, start, arg, flag); } #else #include <sys/sysinfo.h> #include <sys/proc.h> #endif static void __attribute__((constructor)) trap_unaligned(void) { unsigned int buf[2]; buf[0] = SSIN_UACPROC; buf[1] = UAC_SIGBUS | UAC_NOPRINT; setsysinfo(SSI_NVPAIRS, buf, 1, 0, 0, 0); } #endif /* alpha */ void foo(char *a, char *b) { } void showinfo() { char uname[33] = "", tty[38] = "/dev/"; foo(uname, tty); } int main() { showinfo (); exit (0); }
