The eventlog 0N/A// often provides crucial information about events leading up to the crash. 0N/A// All arguments past the format string must be passed as an intptr_t. 0N/A// To log a single event use: 0N/A// Events::log("New nmethod has been created " INTPTR_FORMAT, nm); 0N/A// To log a block of events use: 0N/A// EventMark m("GarbageCollecting %d", (intptr_t)gc_number); 0N/A// The constructor to eventlog indents the eventlog until the 0N/A// destructor has been executed. 0N/A// IMPLEMENTATION RESTRICTION: 0N/A// Max 3 arguments are saved for each logged event. 0N/A // Logs an event, format as printf 0N/A // Prints all events in the buffer 0N/A // Prints last number events from the event buffer 0N/A // log a begin event, format as printf 1879N/A#
