cannot generate Ftargets about aflgo HOT 5 CLOSED

FYI, there are many people failed to use AFLGO with llvm-5.0, before more experienced people commenting to this post, I would suggest you trying llvm-4.0 if you tool can support it.

I used llvm-4.0 when I work with AFLGO. I use llvm-5.0 for my own tool. In both tools (my tool and AFLGO), I did a very simple thing: for each instruction, output the line number to a file. However, in AFLGO, that file does not have the line I want to reach.

Some updates: I changed my tool and used llvm-4.0 for my tool. The file with all line numbers contains the target line...

I found a solution to this problem. I commented line 217 of afl-clang-fast.c(https://github.com/aflgo/aflgo/blob/master/llvm_mode/afl-clang-fast.c). It makes sense to me to not use -O3 optimization, but I am not very familiar with AFL.

Great suggestion! Closing as fixed (in commit d98ad65).
