The experiments can be used to evaluate potential optimizations that remove instrumentation (assess false negatives). Instead of completely removing some instrumentation, you set Exp to a non-zero value (mask of optimization experiments that want to remove instrumentation of this instruction). If Exp is non-zero, this pass will emit special calls into runtime (e.g. __asan_report_exp_load1 instead of __asan_report_load1). These calls make runtime terminate the program in a special way (with a different exit status). Then you run the new compiler on a buggy corpus, collect the special terminations (ideally, you don't see them at all -- no false negatives) and make the decision on the optimization. The exact reaction to experiments in runtime is not implemented in this patch. It will be defined and implemented in a subsequent patch. http://reviews.llvm.org/D8198 llvm-svn: 232501
