RTL generation ??


Hello,
While generating RTL for a function declaration tree, it generates RTL in 3 phases. One is for start of the function by calling expand_start_function(), then expand_stmt() for function body and then expand_end_function() for function exit.
But can any body tell how is the link maintained between the RTLs generated in all these phases ?? What are the functions related to keep links between the RTLs generated in diffrent phases ??

Thanks in Adv.
Mishra
