- InsTrim: three bug fixes:
1. (minor) no pointless instrumentation of 1 block functions
2. (medium) path bug that leads a few blocks not instrumented that
should be
3. (major) incorrect prev_loc was written, fixed!
- afl-clang-fast:
- show in the help output for which llvm version it was compiled for
- now does not need to be recompiled between trace-pc and pass
instrumentation. compile normally and set AFL_LLVM_USE_TRACE_PC :)
