[llvm-commits] [PATH] Add an api to disable PrettyStackTrace

[Zoltan Varga]

Hi,

  The PrettyStackTrace class adds signal handlers for various signals to be
able to catch fatal signals. This causes problems for
host applications which handle signals their own way, like vm's/gc's. The
attached patch adds a global to switch off the
registration of signal handlers.

                                  Zoltan
