Re: [Open64-devel] Is there critical edges existed in wopt?

[Hucheng Z. <zho...@gm...>]

I have checked the code, as following:

 if (WOPT_Enable_Edge_Placement && phase == MAINOPT_PHASE) {
    INT count = comp_unit->Cfg()->Remove_critical_edge();

So it seems that critical edge won't exists in WOPT,
if WOPT_Enable_Edge_Placement is TRUE.

Thanks.
