PPC has a compare-and-trap instruction that is used for NullChecks and RangeChecks. If a check fails, SIGTRAP is raised and must be handled by the signal handler of the VM. Add support for handling SIGTRAP on PPC64 to linux. ---------------------------- This is preparation for PPC64 integration: http://openjdk.java.net/jeps/175 This and following ppc64 changes will go into staging repository first and tested there: http://hg.openjdk.java.net/ppc-aix-port/stage/ http://hg.openjdk.java.net/ppc-aix-port/jdk8/hotspot/file/338e318f1e12/ppc_patches/0214_linux-Extend_signal_handler_to_catch_SIGTRAP_on_ppc.patch
