Re: how to load a cfg from a file by tree-ssa
Thanks,
that message explain how to save a cfg to a file:
Call dump_flow_info() defined in cfg.c to output the pred and succ of
each block. You can use this output to construct the CFG.
but i don't know how to load that file in a structure.
I.e. i have the file .cfg builded by gcc with the option
-fdump-tree-cfg and i want to load this file in a C structure so i can
manipulate it.
Thanks to all,
Andrea
