Hi Evgeny,
Thanks for looking into the patch. I think the reason dom frontier is deprecared is that it is costly to calculate the same.. im not sure as well though.
Im currently using postdom frontier to get the basic block boundry till which a store might overwrite a memory location making it dead. Dead store elimation without having postdom seems to be a bit tough especially given the overhead it would require without postdom.
Thanks
Karthik
