More signal cleanups. Mostly tested by temporarily adding an abort, divide by zero, undefined instruction, null dereference, within the implementation of a guest syscall to induce an error.Changes for v5: * Remap guest abort, which means we need to try less hard on the host side to handle assertion failures. * Drop the backtrace. Since backtrace_symbols only looks at the dynamic symbol set, we don't much that's useful -- we still need to use the debugger. r~ Helge Deller (1): linux-user: Detect and report host crashes Richard Henderson (8): linux-user: Split out die_with_signal linux-user: Exit not abort in die_with_backtrace linux-user: Only register handlers for core_dump_signal by default linux-user: Map unsupported signals to an out-of-bounds value linux-user: Simplify signal_init linux-user: Split out host_sig{segv,bus}_handler linux-user: Detect and report host SIGILL, SIGFPE, SIGTRAP linux-user: Remap guest SIGABRT linux-user/signal.c | 452 +++++++++++++++++++++++++++++--------------- 1 file changed, 296 insertions(+), 156 deletions(-)
