LinkedIn ------------ Bug,
I'd like to add you to my professional network on LinkedIn. - Paulo Paulo Cezar Platform Researcher and Developer at INdT São Paulo Area, Brazil Confirm that you know Paulo Cezar https://www.linkedin.com/e/-g11m92-go1e59vx-23/isd/2968180228/v_gmfnNW/ -- (c) 2011, LinkedIn Corporation -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/696834 Title: FP exception reporting not working on NetBSD host Status in QEMU: New Bug description: I recognize that NetBSD is not one of the officially supported host OS. However, qemu 0.13.0 is available in the NetBSD pkgsrc collection, and works quite well. Well, with one exception (pun intended): It seems that Floating Point exceptions don't get reported properly. The following code-snippet demonstrates the problem: volatile int flt_signal = 0; static sigjmp_buf sigfpe_flt_env; static void sigfpe_flt_action(int signo, siginfo_t *info, void *ptr) { flt_signal++; } void trigger(void) { struct sigaction sa; double d = strtod("0", NULL); if (sigsetjmp(sigfpe_flt_env, 0) == 0) { sa.sa_flags = SA_SIGINFO; sa.sa_sigaction = sigfpe_flt_action; sigemptyset(&sa.sa_mask); sigaction(SIGFPE, &sa, NULL); fpsetmask(FP_X_INV|FP_X_DZ|FP_X_OFL|FP_X_UFL|FP_X_IMP); printf("%g\n", 1 / d); } printf("FPE signal handler invoked %d times.\n"); }
