Profiling Scalar Replacement

[ChenGuang Sun]

Hi,

    I'm trying to profile the number of allocations scalarized by
escape analysis. I modified
PhaseMacroExpand::process_users_of_allocation like follows:

  ...

  const TypeFunc *increment_call_type =
OptoRuntime::increment_alloc_count_Type();
  int size = increment_call_type->domain()->cnt();
  CallNode *call =  (CallNode*)new (C,
increment_call_type->domain()->cnt()) CallLeafNode(
        increment_call_type,
        CAST_FROM_FN_PTR(address, SharedRuntime::increment_alloc_count),
        "increment_alloc_count",
        TypeRawPtr::BOTTOM);

  // Set fixed predefined input arguments
  call->init_req( TypeFunc::Control, alloc->in(TypeFunc::Control) );
  call->init_req( TypeFunc::I_O, alloc->in(TypeFunc::I_O) );
  // Narrow memory as only memory input
  call->init_req( TypeFunc::Memory, alloc->in(TypeFunc::Memory));
  call->init_req( TypeFunc::FramePtr, top() /* frameptr() */ );
  call->init_req( TypeFunc::ReturnAdr, top() );
  call->init_req(TypeFunc::Parms+0, transform_later( new (C, 1)
ThreadLocalNode() ));
  call = (CallNode*)transform_later(call);
  /*
  if (_fallthroughcatchproj != NULL) {
    _igvn.replace_node(_fallthroughcatchproj, alloc->in(TypeFunc::Control));
  }
  if (_memproj_fallthrough != NULL) {
    _igvn.replace_node(_memproj_fallthrough, alloc->in(TypeFunc::Memory));
  }
  */
  if (_fallthroughcatchproj != NULL) {
    _igvn.replace_node(_fallthroughcatchproj, transform_later( new (C,
1) ProjNode(call, TypeFunc::Control) ));
  }
  if (_memproj_fallthrough != NULL) {
    _igvn.replace_node(_memproj_fallthrough, transform_later( new (C,
1) ProjNode(call, TypeFunc::Memory) ));
  }
  if (_memproj_catchall != NULL) {
    _igvn.replace_node(_memproj_catchall, C->top());
  }
  if (_ioproj_fallthrough != NULL) {
    _igvn.replace_node(_ioproj_fallthrough, transform_later( new (C,
1) ProjNode(call, TypeFunc::I_O) ));
  }
  if (_ioproj_catchall != NULL) {
    _igvn.replace_node(_ioproj_catchall, C->top());
  }
  if (_catchallcatchproj != NULL) {
    _igvn.replace_node(_catchallcatchproj, C->top());
  }


But the functions corresponding to the CallLeafNode is never called.
Could any one tell me what's wrong with my modification please?

Thanks,
Chenguang
