commad "dot" cannot show the complete the control-flow graph in the QED-CFCSS

Dear all,

I used the command “opt -view-cfg <src.bc> /dev/null” on ODROID-C2 board (armv8 architecture), however the result of cfg is not complete, it only shows control-flow-graph of one function.

Does anyone ever come across this question and just give me some suggestions? Thanks!


Do you want the control flow graph of all functions, or do you want an inter-procedural call graph (the two are not the same)? Regards, John Criswell
