This change moves "DefaultVLIWScheduler" class declaration from
DFAPacketizer.cpp to DFAPacketizer.h.
This is needed because there is a protected class member of
type "DefaultVLIWScheduler*" in "VLIWPacketizerList" class.
The derived classes cannot use this memeber unless declaration
is available to it. More specifically :
// Without this change
class HexagonPacketizerList : public VLIWPacketizerList {
public :
HexagonPacketizerList() {
// Below line will cause incomplete class error since
// declaration was not available through header.
VLIWScheduler->schedule();
}
}
