(jdk10) RFR(xxs): 8176872: [s390] wrong pc shown in error logs
by Thomas Stüfe 04 Apr '17

Hi all, please take a look at this tiny fix. It fixes the pc shown as faulting address for SIGILL and SIGFPE in hs_err files. https://bugs.openjdk.java.net/browse/JDK-8176872 http://cr.openjdk.java.net/~stuefe/webrevs/8176872-s390-wrong-pc-in-errorlo… When determining the crash pc, in all posix platform signal handlers pc is taken from the context. However, context.pc on zlinux points to the instruction *after* the faulting op. The correct way, according to POSIX, would be to take the address from siginfo_t->si_addr for signals SIGILL, SIGFPE. (actually, this patch would make sense for all POSIX platforms, but only s390 seems to show this error, so I leave the patch local to s390.) Kind Regards, Thomas
