This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
The new command add functionality to print out domain specific information for reporting a bug. Currently the only supported domain is stack unwinding (with "bugreport unwind") but adding new domains is fairly easy. Differential revision: http://reviews.llvm.org/D10868 llvm-svn: 241252
