- all queue, hang and crash files now have their discovery time in their name
- if llvm_mode was compiled, afl-clang/afl-clang++ will point to these
instead of afl-gcc
- - added gcc_plugin which is like llvm_mode but for gcc. This version
- supports gcc version 5 to 8. See gcc_plugin/README.gcc
- (https://github.com/T12z/afl)
- added instrim, a much faster llvm_mode instrumentation at the cost of
path discovery. See llvm_mode/README.instrim (https://github.com/csienslab/instrim)
- added MOpt (github.com/puppet-meteor/MOpt-AFL) mode, see docs/README.MOpt
