// FP value associated with _last_Java_sp:
public:
// Each arch must define reset, save, restore
// These are used by objects that only care about:
// 1 - initializing a new state (thread creation, javaCalls)
// 2 - saving a current state (javaCalls)
// 3 - restoring an old state (javaCalls)
void clear(void) {
// clearing _last_Java_sp must be first
// fence?
}
// In order to make sure the transition state is valid for "this"
// We must clear _last_Java_sp before copying the rest of the new data
//
// Hack Alert: Temporary bugfix for 4717480/4721647
// To act like previous version (pd_cache_state) don't NULL _last_Java_sp
// unless the value is changing
//
// Must be last so profiler will always see valid frame if has_last_frame() is true
}
// Always walkable
bool walkable(void) { return true; }
// Never any thing to do since we are always walkable and can find address of return addresses
