Hi, all

At the end of the link belows,
http://gcc.gnu.org/onlinedocs/gccint/Maintaining-the-CFG.html#Maintaining-the-CFG
It says,
"Note that at present, the representation of control flow in the tree
representation is discarded before expanding to RTL. Long term the CFG
should be maintained and "expanded" to the RTL representation along
with the function tree itself."
Does this mean in the end of GCC compilation, the CFG information is
lost? Thanks!
