- Subject: printing ddg for each basic block
Hi all:
I need to print ddg for each basic block in CFG. I used option -dv.
However, it gives a DAG for CFG where each node is a basic block. I
see a function "vcg_print_ddg(FILE* file, ddg_ptr)" in the ddg.c file.
It means that you can have a ddg for each basic block in the CVG
format. How can I activate this using gcc options like -dv etc.?
