ChangeLog:
* config/s390/linux.h (MD_FALLBACK_FRAME_STATE_FOR): For SIGSEGV and
SIGBUS signal frames, the PSW address points *to* the faulting
instruction, not after it.
libjava/ChangeLog:
* include/s390-signal.c (SIGNAL_HANDLER): Use SIGINFO-style prototype.
(struct old_s390_kernel_sigaction): Likewise for k_sa_handler.
(MAKE_THROW_FRAME): Do not modify PSW address.
(INIT_SEGV): Install SIGINFO-style signal handler.
(INIT_FPE): Likewise.
git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@84506 138bc75d-0d04-0410-961f-82ee72b054a4
